spirent network impairment emulators

SPIRENT NETWORK IMPAIRMENT EMULATORS
VALIDATING FCOE SOLUTIONS
Spirent Network Impairment Emulators enable users to validate and evaluate new products
and technologies by accurately emulating the delays and impairments that occur over live,
or production, Ethernet networks.
APPLICATIONS
•
Characterize Fibre Channel throughput in the presence of
converged traffic and Ethernet impairments
•
Validate Fibre Channel over Ethernet implementations with
full line rate 10Gb/s Ethernet network emulation
•
Characterize the performance of new technologies required to
support Fibre Channel transport over Ethernet
The imperative to achieve time-to-market (TTM) advantage in the
highly competitive Fibre Channel over Ethernet market creates
significant challenges for companies that design and develop
FCoE products. FCoE equipment manufacturers and service
providers need to be able to:
•
Duplicate real-world network conditions dynamically in a
consistently reproducible and controlled environment
Stress the addressing scheme (SPMA or FPMA) by corrupting
or modifying MAC addresses
•
Flexibility to test standards-based or proprietary
implementations while standards are not finalized
Verify proper support for IEEE 802.3x PAUSE and prioritybased flow control
•
Test FCoE links at full-line rate 10Gb/s full-duplex for
comprehensive testing and validation of products
•
Rapidly reproduce field issues in the test lab for swift
troubleshooting and fast problem resolution
•
Verification of QoS enforcement in the presence of congestion

NETWORK IMPAIRMENT EMULATORS
Spirent’s 10G Ethernet network emulator (XGEM) offers users a
proven solution to these challenges - providing the flexibility and
repeatability needed to ensure performance issues can be readily
tested and issues quickly addressed throughout the development
or deployment process. Specifically, the Spirent XGEM Network
Impairment Emulator platform provides users with the ability to:
•
Perform testing at full line-rate 10 Gb/s
•
Target specific packets for impairment based on Ethertype,
FCoE, FIP, FC or other header fields
•
Filter on any data in the PDU for impairment or modification to
facilitate functional testing and feature validation
•
Analyze bidirectional responses to corrupted or dropped
packets
•
•
Validate proper enforcement of Fibre Channel lifetime
requirements
Ensure Fibre Channel lifetime requirements are not enforced
on IP traffic
•
Verify priority-based flow control, congestion management
and enhanced transmission selection capabilities
•
Validate support for Jumbo packets of 2.5KBytes and larger
•
Utilize the programmable filter library to provide bandwidth
statistics per application type
•
Capture incoming packets at 10Gig line rate for analysis—including
bidirectional time correlation—based on filters and triggers
FEATURES
•
Support for all proprietary and standard L3—L7 protocols
including IPv6
•
Jumbo frame support—infinite size (12K bytes for reorder and
duplication)
•
Multi-protocol support (SONET, SDH, OTN, Fibre Channel,
CPRI, and Ethernet) on the same chassis; grow easily as
needs change
BENEFITS
•
Reduce risk and time to market by validating performance
under real world conditions with precise and reproducible
results prior to first customer shipment
•
Realistic problem replication for troubleshooting
•
Improves Proof of Concept testing and customer demonstrations
•
Dynamically changing impairment profiles
•
Easy configuration with standards-based models
•
Field programmable architecture protects investment
•
Multi protocol support (Ethernet, SONET/SDH, OTN, CPRI
and Fibre Channel)
TECHNICAL SPECIFICATIONS
Network Profiles
•
Support for up to 16 distinct network profiles emulating 16
“network clouds” per blade
•
Define bandwidth, delay and impairments for each profile
•
Each profile can be defined by any combination of VLAN tag,
MPLS label, MAC or IP address TCP/UDP port or any value up
to 2000 bytes deep within the Ethernet frame
•
Hardware-based architecture provides maximum accuracy and
repeatability
•
100% line rate (up to 11.3Gbps) capable even with minimum
size frames
•
Precisely emulate delays and impairments that occur over
Ethernet networks including:
•
Emulates static or variable delay occurring during
transmission of Ethernet data through a network
•• Static and Variable Delay (Packet Jitter)
•
Introduce frame or packet delay variation (jitter)
•
Optional delay extenders are available for extra delay
Delay
•• Packet Corruption, Drop, Reorder, Duplication, Modification
•• 10-bit domain line bit errors, LOS, comma aligner bit rotation
•
•
•
Define up to 16 network profiles per interface with separate
delay, bandwidth and impairments for emulating different
classes of service or multiple paths through a network
Ability to dynamically change impairment profile without data
loss or test restart
Standards-based Network Impairment Models per TIA-921
and ITU-T G.1050 MEF-18/G.8621
