Preface
Revised: February 2016
Cisco Videoscape Distribution Suite (VDS) Transparent Caching (TC) Analytics provides visibility into
network performance, subscriber trends, and cache content. This business intelligence engine leverages
industry leading technology for the monitoring, reporting, and analysis of key performance indicators
(KPIs) with unique insight from the Cisco VDS TC cache engines.
The core of the Cisco VDS TC Analytics solution consists of KPIs and a Cache Detail Record (CDR)
database, which the VDS TC Analytics server uses to collect and store information from the Cisco VDS
TC cache engines. Cisco VDS TC systems on the network are connected to the foundation over the ISP
management network. Details from these cache engines are aggregated and analyzed to enable a
network-wide view of traffic, as it is delivered from the perspective of the VDS TC cache engines.
Administrators access this information through a central Cisco VDS TC Analytics server by viewing
dashboards and pre-defined reports, and can perform on-demand analysis of the network.
Analysis is delivered for all levels of the organization in a variety of displays. Different report packages
are available for various levels of the organization:
•
Network engineers obtain the details required for managing and expanding their networks.
•
The finance department can gain visibility into savings and growth planning.
•
Executives can draw summaries based on media trends and subscriber patterns
•
The marketing team can acquire insight necessary to develop new products and services.
Information is presented as webpage dashboards, which provide quick access to information, or in PDF
and HTML formats.

Overview
Cisco VDS TC Analytics provides a high quality and rich variety of marketing and network engineering
performance reports. These dashboard reports provide the most important and valuable performance
KPIs that give a clear view of the business status. By just clicking the main window, the user has access
to the Dashboard Reports Navigation.

Preface
Cisco VDS TC Analytics Navigational Overview
The VDS TC Analytics data collection engine and data intelligence system produces custom reports
about the media that flows through the entire pipeline. These reports are designed to provide analytical
answers to key business questions, such as content type distribution, the percentage of users driving
bandwidth growth, new and potential services, P2P class of service, the popularity of users by protocols
or services, individual system output, cache consumption, the IP addresses of the highest volume users,
services that are consumed by the highest volume users, weight items and number of requests, overall
load balance, and so on.
VDS TC Analytics translates the data that is generated by VDS TC cache engines and displays it in
charts and data tables designated according to specific Cisco Analytics user groups, such as network
engineers and operators, marketing personnel, and executives.
For each organizational user group, VDS TC Analytics presents pertinent information in predefined sets
of displays. The At a Glance dashboard is the summary page that opens for each of the organization user
groups, delivering an immediate overview at patterns and trends. At a Glance reports present the daily
summaries for the time frame you select, according to daily average values, breaking down the
information by services and protocols. Plotted comparisons of information visually convey the behavior
of traffic, as it is served from the VDS TC cache engine (cache traffic) and from the world (clear traffic).
You can easily list all charted data in numerical values to enhance your insight.
From this personalized dashboard look, you can drill down for more detailed analysis available through
the Data Mining dashboard. The Data Mining reports offer advanced filtering capabilities, according to
five minute polling, for the comparison of KPIs across services and protocols over any time frame.
Aggregate views for the entire network can be compared by IP address, zone, POP, or individual VDS
TC systems.
You can save or print every chart and data table in PDF or HTML format.
Cisco VDS TC Analytics Navigational Overview
Cisco VDS TC Analytics has an easy to use GUI to help you navigate to the various dashboards and
reports, which are accessed through the main menu of the VDS TC Analytics user interface (UI).
Clicking each choice allows the user to adjust what they view and how they view it.

Terminology
The VDS TC Analytics Terminology table describes terms and concepts that apply to the VDS TC
Analytics Software.
Table 2
VDS TC Analytics Terminology
Term
Description
AVG
Average
Bytes Hit Ratio (BHR)
The number of bytes of cached out traffic divided by the total number of
bytes of traffic, whether it was cached or not. For example, a 60% bytes hit
ratio means that 60% of the overall bandwidth came from the cache and
40% came from the world.
cache in
A connection where the object requested by a subscriber does not exist in
the cache (which creates a “miss”), and the requested incoming data from
the world is stored in the cache.
cache
Traffic served only from VDS TC.
cache out
A connection where the object requested by a subscriber exists in the cache
(which creates a “hit”), and the request is served from the cache as outgoing
traffic to the subscriber.
cache productivity
The total cached out traffic divided by the total cached in traffic.
cache quality of
experience (QoE)
The average delivery speed of traffic that is served from VDS TC per active
subscriber. QoE is analyzed by comparing cache QoE with clear QoE.
CDR
Cache/Content Data Record
clear
The status of a subscriber request when the requested file segment does not
exist in the cache. Subsequently, this object is either cached in or forwarded.
It is considered as traffic that is delivered directly from the Internet.
clear QoE
The average delivery speed of traffic served directly from the Internet (VDS
TC clear) per active subscriber. QoE is analyzed by comparing clear QoE
with cache QoE.
CLI
command-line interface
CMDB miss
The status of a subscriber request when the requested file segment does not
exist in the cache due to an unexpected deletion or corruption.
data
A connection where P2P or HTTP file segments are transferred.
downstream
Objects transmitted from the world to the subscriber. Also called W2I.
forward
The process of forwarding an object directly to its requesting subscriber
without caching it. This is applied to an object that does not yet exist in the
cache. At this stage, it is only listed in the cache, according to the predefined
license rules of the platform (see verify), and will only be cached upon
future request.
hit
The status of an ISP subscriber request when the requested file segment
exists in cache. Subsequently, this object is cached out.
hit miss ratio
The number of hits divided by the number of misses.
I2W
Upstream data flowing from the ISP to the world.

Quality of Experience : The Quality of Experience report allows analysis and comparison of the
quality of experience of the network. QoE is measured by comparing the speed of content served
from Cisco Analytics (Cache) with the speed of content arriving directly from the World Wide Web
(Clear). QoE is presented for the entire network.
Data Mining for Marketing
The Data Mining Marketing reports provide an inclusive filtering mechanism that allows you to gather
specific information, uncovering traffic, domain, and IP patterns for individual systems. Data Mining is
intended for drilling-down into the performance of specific systems, top subscribers, and top domains,
by services or protocols. Data Mining presents five minute polling values (At a Glance charts are based
on daily average values), arranged in the following charts and data tables.
•

General Notes for Charts and Reports
•
Current day information not available: Because IP information is collected between 00:01 and
24:00 each day, and only analyzed after it is collected, no information is available for the current
day for reports that require IP address and domain information. Therefore you can only present
information up to the previous day. IP and domain information for the current day can only be
presented the day after.
•
Selected time frame determines granularity: The selected time frame determines the chart
granularity. A chart or report with a time frame of up to and including 3 days, displays five minute
polling values. A chart or report with a time frame from 4 days to 30 days displays hourly average
points, which calculate all the five minute samples in each hour. A chart or report that has a time
frame of over 30 days displays only daily average values.
Content Analysis
The Content Analysis reports enable you to analyze the subscriber traffic patterns, by default filtered by
services, for the selected time frame, which by default is the last seven days. Information can be
displayed for a specific user, by either services or protocols. You can also filter the information that is
displayed based on systems, zone, POP, domain, subscriber IP, and host IP. By default, information is
displayed as numerical values. You can also choose to display information is as a pie chart and bar charts.
In this tab, the default Filter By preferences are set to display the previous seven days for the entire
network by services, sorted by Subscribers Popularity. You can filter information by a specific user, by
either services or protocols, and you can filter out several systems

General Notes for Charts and Reports
•
Current day information not available: Charts that rely on information for IPs and domains
require an additional day for analysis. Because IP information is collected between 00:01 and 24:00
each day, and only analyzed after it is collected, no information is available for the current day,
therefore you can only present information up to the previous day. IP information for the current day
can only be presented the day after.
Traffic Analysis
The Traffic Analysis tab delivers immediate visibility of the system performance, based on the selected
time frame, which by default is the current week. This summarized view focuses on the overall
subscriber consumption, or total downstream traffic, in comparison with the cached out traffic. This tab

stands for “million”. In this chart protocols are represented by different colors and overlaid on each
other.
Peak Traffic Analysis
The Peak Traffic Analysis reports provide visibility into the values of network downstream traffic during
the peak bandwidth, for each day. The charts compare various views of the peak subscriber consumption,
or peak total downstream traffic, and cache out traffic, and of peak byte hit ratio and cache productivity
ratio. Peak BHR is analyzed by comparing total downstream traffic and cache out traffic. Peak cache
productivity is analyzed by comparing downstream incoming traffic and downstream cache out traffic.
By default, information is displayed as a chart. You can generate a data table to list the plotted values.

In the charts, the total downstream traffic and cache out downstream capacity are presented in bps for
the selected time frame, where M in the Y axis stands for “million”. For the default time period of one
week, each line is plotted between points that represent the daily average value. If you select a shorter
time frame, such as one or two days, the curve is then plotted between points that represent 5 minute
average values.

systems. Augmenting the At a Glance panel that provides an immediate overview of the entire network,
Data Mining is intended for drilling-down into the performance of specific systems, top subscribers and
top domains, by services or protocols. The Data Mining tabs present five minute polling values (At a
Glance charts are based on daily average values), arranged in the following tabs:

General Notes for Charts and Reports
•
Current day information not available: Because IP information is collected between 00:01 and
24:00 each day, and only analyzed after it is collected, no information is available for the current
day for reports that require IP address and domain information. Therefore you can only present
information up to the previous day. IP and domain information for the current day can only be
presented the day after.
•
Selected time frame determines granularity: The selected time frame determines the chart
granularity. A chart or report with a time frame of up to and including 3 days, displays five minute
polling values. A chart or report with a time frame from 4 days to 30 days displays hourly average
points, which calculate all the five minute samples in each hour. A chart or report that has a time
frame of over 30 days displays only daily average values.
Content Analysis
The Content Analysis reports enable you to analyze subscriber traffic patterns, filtered by services (the
default in this tab), for the selected time frame, which is the last seven days by default. You can filter the
information for a specific subscriber IP, by either services or protocols, and you can filter traffic based
on the zone, POP, and system. Information is displayed in numerical values and with horizontal bars to
provide visualize comparisons within each column. You can also choose to view the data in charts as
well.
In this tab, the default Filter by preferences are set to display information for all subscribers, for all
systems, by services. You can filter information by a specific IP address, select only services or

Policy Reports
The Policy Analysis Dashboard provides an assortment of comprehensive reports that capture the
statistics about traffic based on the rules, policies, and categories the traffic fall into.
All explicitly created policies are global and are not connected to any configuration. If a global policy
is changed, it will be changed in all of the configuration versions. All implicitly created policies are
connected to their rules; they are not shown in the policies list and are deleted together with the rules.
This chapter describes the information that can be viewed from the Policy Analysis Dashboard and
contains these sections:

•
Current day information not available: Because IP information is collected between 00:01 and
24:00 each day, and only analyzed after it is collected, no information is available for the current
day, therefore you can only present information up to the previous day. IP information for the current
day can only be presented the day after.
•
Selected time frame determines granularity: The selected time frame determines the chart
granularity. A time frame of less than 3 days displays five minute polling values. A time frame of
over 3 but less than 33 days, displays hourly average points, calculating all of the five minute
samples in each hour. A time frame of over 32 days reduces chart granularity to display only daily
average values.
Categories Analysis
The Categories Analysis reports provide visibility into content compared by the category that the traffic
falls into displayed as both a daily average and as a total for the time frame that is selected. It displays
information for total traffic, cache traffic, and clear traffic broken down by both requests and capacity.

Reports
The QoE Analysis tab displays the following reports:
•
Quality of Experience for Entire Traffic: This chart presents the QoE, calculated across all
systems for all services and protocols. You can use the Filter By section to determine which services
or protocols to include in the calculation. QoE is indicated by comparing between Cache QoE and
Clear QoE, for the selected time frame. The lines are plotted according to daily average polling
values, and presented in Mbps. The higher the Cache QoE line is above the Clear QoE line, the
higher the QoE, with a higher level of network traffic being delivered faster by VDS TC. To display
the information in the chart as a data table, from the Detailed Analysis drop-down list choose Data
Table.
To present a generalized view of this information, by daily average polling values, see the Quality
of Experience Comparison by Protocol chart on the Network Engineering > At a Glance, Services
QoE tab. To drill down into the information by individual systems, see the Systems Quality of
Experience by Service chart on the Network Engineering > Data Mining, Systems QoE Analysis tab.
•
Network Acceleration Ratio for Entire Traffic: This report presents the QoE as a single Ratio line
between cache and clear, calculated across all systems for all services and protocols. You can use
the Filter By section to determine which services or protocols to include in the calculation. Improved
acceleration is indicated by VDS TC servicing traffic faster than the speed of traffic arriving from
the world.
To present a generalized view of this information, by daily average polling values, see the Quality
of Experience Comparison by Protocol chart on the Network Engineering > At a Glance, Services
QoE tab and choose Ratio in the For drop-down list. To drill down into the information by individual

Frequently Asked Question
Revised: February 2016
This appendix provides answers to some frequently asked questions about VDS TC Analytics.
Time Frame
What is the default time frame for the reports?
The default time from for reports vary, although most of the reports have a default time from of the
last seven days. You can change the time frame at anytime. In the Filter By section enter the From
and To dates that you want, or use the calendar to select them, and then click Apply. The dates
appear in MM/DD/YY format. The chart or report is regenerated for the new time frame and the time
frame is displayed in brackets in the chart or report title bar. The new time frame that you enter is
passed on to the other tabs in the same dashboard.
Does the selected time frame change the plotted value and chart granularity?
In Data Mining, the selected time frame determines chart granularity. A chart or report with a time
frame of up to and including 3 days, displays five minute polling values. A chart or report with a
time frame from 4 days to 30 days displays hourly average points, which calculate all the five minute
samples in each hour. A chart or report that has a time frame of over 30 days displays only daily
average values.
How do you determine the time frame to be displayed?
You can change the time frame at any time and in any report, using the Filter By section of each tab.
The filtering preferences that are set in one tab are automatically carried on to all of the other tabs
in that specific dashboard.
Why is there no information displayed for the current day?
Because content information is collected between 00:01 and 24:00 each day and only then analyzed,
information for the current day is unavailable in some tabs. Although the last seven days is the
default Data Mining time frame, in the Top Subscribers, Top Contents, and Traffic Distribution tabs
you can only present information up to the previous day. Current day IP or domain information can
only be presented the day after.

Appendix A
Frequently Asked Question
Filtering
Why is there a discrepancy in traffic patterns?
If traffic patterns do not make sense, it could be because the clocks of the VDS TC Analytics Server
and the VDS TC cache engines are not synchronized, causing a time mismatch.
Is daylight savings time automatically supported?
Daylight savings time is not supported. You must resynchronize the VDS TC Analytics clock and
the VDS TC cache engine clocks, to ensure accurate display of information.
Filtering
How is data filtered for display?
In each tab, Filter By settings define the data querying preferences. You can change filtering
preferences at any time and in any tab. Filtering preferences are carried on to all of the other tabs in
a dashboard, but not between dashboards.
At a Glance provides simplifies filtering options that only allow time frame filtering. Data Mining
provides in-depth filtering options, allowing you to set specific systems criteria and display either
services or protocols. Note that you must click Apply to refresh the page and display the information
according to what you selected in Filter By.
Note
Different reports in the Data Mining tabs will have different Filter By options, depending on what the
report is showing.
Why is no information presented for the current day?
Charts that rely on data of IPs and domains require an additional day for analysis. Because
information is collected between 00:01 and 24:00 each day, and then analyzed, no information is
available for the current day. Even when the default time frame includes the current day, you can
only present information up to the previous day for charts that rely on data from IPs or domains.
Current day IP or domain information can only be presented the day after.
Why is the display not refreshed to show latest filtering selection?
After making a new selection in the Filter By section, you must always click Apply. Clicking Apply
refreshes the charts to present the newly selected filtering criteria.
Data Collection
How is data collected by Analytics?
VDS TC Analytics retrieves information from SNMPs that are generated and controlled by your
Cisco Analytics management server(s). Upon installation, the VDS TC Analytics architecture and
collector parameters are set using the Configuration tab.
How to change SNMP poll intervals and CDR data collection?
SNMP polling and CDR data collecting parameters are defined in the Configuration tab. By default,
SNMP polling intervals are every 5 minutes. To change these values you must be assigned to either
the Admin or User group and you must be assigned the Network Engineering Values package.
