FLEXIBLE TRAFFIC MAPPING
QOS
ETHERNET OAM
Traffic is mapped to the Ethernet flows
(EVCs) using very flexible classification
criteria that can be combined, for
example:
Different service types require different
levels of QoS to be provided end-to-end.
QoS can be defined per subscriber as well
as per service. QoS has three aspects: rate
limitation, traffic shaping, and traffic
prioritization.
Featuring ultra fast, hardware-powered
processing, ETX-203A performs OAM and
PM measurements in line rate with
maximum precision, offering the following
powerful benefits:
•
VLAN + VLAN priority
•
VLAN + IP precedence
•
VLAN + DSCP
•
Ether Type
•
IP/MAC source/destination address
•
Untagged.
More classification criteria and
combinations can be found in the user
manual.
HIERARCHICAL SCHEDULING AND
SHAPING PER FLOW
Every flow has its own queues and
scheduler. ETX-203A supports up to
192 flows, and a total of 16 or 30 queue
blocks per network port. Each queue block
is a group of eight queues per CoS. Each
flow can be bound to each queue block.
Traffic policing is applied per flow or group
of flows, and operates according to the
dual token bucket mechanism based on
user-configurable CIR + CBS and EIR + EBS.
Traffic can be limited to the line rate or
the data rate.
For prioritizing user traffic, ETX-203A
maps user traffic to up to eight separate
queues per service. Each can be
configured as strict priority queues or
weighted fair queues (WFQ).
Immediate detection of loss of
continuity (LOC), ensuring under 50ms
protection switching
•
Highly accurate frame loss
measurements with live traffic testing
•
Flow-level monitoring, enabling
simultaneous processing of hundreds
of OAM sessions
•
Loopback testing at line rate.
ETX-203A provides these types of
Ethernet OAM:
•
Single-segment (link) OAM according
to IEEE 802.3-2005 (formerly 802.3ah)
for remote management and fault
indication in active and passive mode,
including remote loopback, dying gasp,
and MIB parameter retrieval.
•
End-to-end connectivity OAM based on
IEEE 802.1ag-D8 that enables Ethernet
service providers to monitor their
services proactively and guarantee that
customers receive the contracted SLA
•
End-to-end service and performance
monitoring based on ITU-T Y.1731.
Fault monitoring and end-to-end
performance measurement include
frame delay, frame delay variation,
frame loss and availability.
The queues handle traffic with different
service demands, such as real-time traffic,
premium data, or best-effort data.
The device uses the WRED policy to
ensure that in case of congestion, green
packets are not dropped (yellow packets
may be dropped).
TYPICAL APPLICATIONS
ETX-203A is used in the following
MEF-defined applications:
•
Figure 1. Ethernet Virtual Private Line
•
Ethernet Private Line (EPL) –
Site-to-site connectivity over
dedicated bandwidth without service
multiplexing (see Figure 1)
•
Ethernet Virtual Private Line (EVPL) –
Site-to-site connectivity over shared
bandwidth with service multiplexing
(see Figure 3)
•
Ethernet LAN – Site-to-site
connectivity over dedicated bandwidth
with or without service multiplexing.
RFC-2544
The device provides a built-in RFC-2544
wirespeed traffic generator and analyzer
for unidirectional and bidirectional testing
of throughput, latency and frame loss. The
tests are done over any Layer-2, based on
standard OAM messages.

NETWORK INTERFACE RESILIENCY
FAULT PROPAGATION
SECURITY
Flow-based resiliency on uplinks is
provided, as well as G.8031 – Ethernet
linear protection on the network ports.
The unit provides a user-configurable fault
propagation mechanism in the
network-to-user or user-to-network
direction. When a link failure is detected
or OAM failure received, ETX-203A can
shut down the affected port or forward
the OAM failure message. The fault
propagation mechanism enables routers
and switches connected to both ends of
the link to reroute the traffic to the
redundancy path.
The following security protocols are
provided by ETX-203A to ensure client
server communication privacy and correct
user authentication:
ETX-203A implements EPS Ethernet Path
protection according to ITU-T G.8031.
The device can protect one or multiple
EVCs in the network via standard APS
messages and via OAM ETH AIS/LOC
criteria, ensuring protection switching
under 50 msec. The protected EVC can run
over one uplink or dual uplinks per
customer requirement.
•
RADIUS (client authentication)
•
TACACS+
•
SSH for Secure Shell communication
session.
Pay-us-when-your-customers-pay-you
business model:
The protection is available for the
following topologies:
The unit can be managed using the
following ports and applications:
•
End-to-end EPS path protection for
one or multiple EVCs transported over
MPLS/VPLS access network
•
Local management via an ASCII
terminal connected to the RS-232 port
•
Opposite standard PE supporting
G.8031 EPS.
•
Additionally, the following protection
methods are provided via port-based
resiliency on the network ports:
Remote inband management via user
or network ports routed via separate
VLANs, Telnet, or a third-party OSS
system
•
Out-of-band management via a
dedicated management port
•
Link aggregation (LAG) based on
802.3ad
•
SFTP – Secure File Transfer Protocol.
•
Dual homing (1:1), allowing ETX-203A
to be connected to two different
upstream devices.

INTEGRATED SMART SFP SUPPORT
Integrated management of smart
MiRIC/MiRICi SFPs provides E1/T1/E3/T3
STM1 or OC3 Eth over PDH or SDH legacy
networks. The ETX-203A management
includes MiRIC/MiRICi configuration and
statistic collection.
The VLAN priority bit in Ethernet frames
can be modified at network ingress
according to the ‘color’ of the frame. This
allows service consistency and QoS
continuity across color-aware (Drop
Eligible-enabled) as well as color-unaware
networks.

LAYER-2/ LAYER-3 LOOPBACK WITH
MAC AND IP ADDRESS SWAPPING
As services and networks become more
complex, tracking service and network
faults is very important for conforming to
the SLA. Therefore it is vital that the
service provider can perform network
loopbacks to easily track failures. Layer-2
and/or layer-3 network integrity can be
tested by a non-disruptive loopback
performed per flow, with swapping of
MAC address and optionally IP address.
When the loopback is activated, ETX-203A
exchanges the source and destination
MAC/IP addresses of the incoming
packets. This loopback passes through
Ethernet bridges (MAC address) and
routers (IP address).
DYING GASP
ETX-203A reports power failures to
defined network management stations by
sending an IEEE 802.3-2005 message and
trap, thus enabling the unit to properly
disconnect from the network with
notification of the reason for the service
problem.
L2CP HANDLING
DHCP
ETX-203A can be configured to pass
through Layer-2 control frames (including
other vendors’ L2CP frames) across the
network, to peer supported protocols
(IEEE 802.3-2005 and LACP), or to discard
the L2CP frames.
IP address, IP mask, and default gateway
can be automatically obtained using DHCP.
COMMAND LINE INTERFACE
JUMBO FRAMES AND EGRESS MTU
Databases and scripts of commonly used
commands can be easily created and
applied to multiple units using command
line interface.
The unit supports large frames of up to
12 Kbytes.
UNIVERSAL POWER SUPPLY
COMPACT SIZE
The ETX-203A power supply inlet can be
connected to AC or DC power.
The unit is supplied in a compact 8.5-inch
1U high enclosure.
MOUNTING OPTIONS
ETX-203A can be rack mounted with a
dedicated RM kit (see ordering options) or
can be wall mounted (see user manual for
instructions).
