SANTA CLARA, California,
December 16, 2010 /PRNewswire/ --
Aviat Networks, Inc. (Nasdaq: AVNW), a leading wireless expert in
advanced IP migration solutions, today announced the release of its
DAC GE3 module and confirmed delivery of first shipments to
multiple leading mobile network operators and other early access
customers. The DAC GE3 provides the most advanced Carrier Ethernet
switch subsystem available in a microwave backhaul platform today.
Featuring higher capacity and an impressive breadth of new
capabilities, this third-generation design sets a new benchmark for
resilient wireless access and aggregation networks:
- To ensure and protect the QoS of real-time traffic while guaranteeing
adequate bandwidth for best effort traffic, a fully configurable Strict
Priority (SP) and Deficit Weighted Round Robin (DWRR) hybrid scheduler
with eight hardware transmission queues is employed. Prioritization of
traffic can be enabled at the physical, data link, MPLS, or IP network
layer, and a proprietary dynamic shaping algorithm instantly adapts the
switch to the bandwidth variations of Adaptive Coding and Modulation
(ACM) microwave links.
- With multiple synchronization schemes for IP networks on the market,
the DAC GE3 card has been tested along with equipment from other
vendors at the European Advanced Testing Center and Carrier Ethernet
World Congress in 2010. In these tests, the viability of Synchronous
Ethernet and IP microwave technologies were determined together for
their suitability in 4G/LTE backhaul applications. The DAC GE3 is
designed to support synchronization through multiple input methods,
Stratum 3 level holdover, and propagation of the signal via the Eclipse
Distributed Sync(TM) feature.
- Carrier grade packet buffers and an extended number of ports and
transport channels provide the ability to act as a traffic concentrator
for purposes of aggregation, and offer superior performance in handling
the transport of excessively bursty traffic.
- Support for bi-directional 1+1 protection switching provides high
availability and service continuity for mission-critical applications
with no single point of failure present in the system.
- Additional Carrier Ethernet features including an integrated Service
OAM MEP (Operation, Administration & Maintenance End Point), Link
Aggregation (LAG), and ring protection mechanisms are scheduled to be
released in early 2011 via software upgrade.
"Initial customer interest in the DAC GE3 has far exceeded our
expectations," said Shaun McFall,
senior vice-president and chief marketing officer of Aviat
Networks. "It has been extremely well received by customers who
have evaluated it, including tier-1 national carriers."
As a plug-in module to the Eclipse Packet Node modular indoor
unit, the DAC GE3 builds on Aviat Networks' field-proven experience
and leadership in delivering versatile and scalable Hybrid and
all-Packet microwave backhaul solutions since the introduction of
the Eclipse nodal wireless system in 2004. It provides a seamless
upgrade for operators around the world who have already deployed
Eclipse, and a high-performance solution for the eventual migration
to an all-IP 4G/LTE (Long Term Evolution) network
infrastructure.
