New DragonWave pseudowire
solution enables migration to packet-based networks and
future-proofs for changes in traffic mix
Ottawa, Canada -- DragonWave Inc. (AIM/TSX: DWI), a leading global
supplier of next-generation wireless networks, today announced its
Service Delivery Unit (SDU) product portfolio, enabling carriers to
efficiently converge Time Division Multiplexing (TDM) and Internet
Protocol (IP) services on a cost-effective, flexible Ethernet
network foundation. In the migration to carrier Ethernet,
DragonWave’s new pseudowire solution fosters a simplified,
future-proofed, packet-based network that is significantly more
affordable to build, power, support and maintain. |

DragonWave will show its new SDU portfolio in Booth 5852 at CTIA
Wireless® in the Las Vegas Convention Center, April 1-3.
“The SDU offers service providers a compelling path
to full-blown carrier Ethernet,” said Todd Graetz, CEO for
Montana-based Cutthroat Communications, a transAria company. “The
ability to convert to packets at the edge of the network and then
pass though intermediate sites as a single, converged, IP-based
stream reduces network costs and significantly simplifies
operations. With the SDU, DragonWave is future-proofing our network
for changes in traffic mix moving forward.”
The new SDU pseudowire solution is another DragonWave tool for
enabling carriers to converge TDM and IP traffic across a single,
wireless Ethernet infrastructure. With the SDU providing both
pseudowire and Ethernet switching functionality, a carrier reduces
investment by deploying a single box for these two functions in its
network.
“The benefits of carrier Ethernet are well understood, but carriers
need the flexibility to make incremental steps in convergence,” said
Emmy Johnson, Principal Analyst with Skylight Research. “They seek
to continue to benefit from legacy investment, even while evolving
for support of new Ethernet services—all while holding capital and
operational expenditures in check.”
There are three versions of the SDU: a 16-port T1/E1 version, a
two-port DS3 version and a one-port OC3/STM1 version. In addition to
supporting point-to-point TDM transport, the SDU can provide virtual
aggregation, further cutting carrier costs by reducing the
requirement for TDM cross-connects in the network; a carrier could
deploy the T1/E1 version of the SDU at multiple remote locations and
aggregate the traffic with the DS3/OC3 version for delivery into the
network core. The DragonWave solution supports up to six Gigabit
Ethernet ports, in addition to the TDM ports. The SDU provides key
carrier-grade features, such as traffic prioritization, Virtual
Local Area Network (VLAN) tagging, Ethernet demarcation and full
redundancy. Up to three SDUs can be deployed in a single standard
carrier equipment rack unit.
“Carriers need tools for keeping their cost of churn low, and we
engineered the SDU with that goal in mind,” said Alan Solheim, Vice
President of Product Management at DragonWave. “The SDU enables
carriers to gradually and cost-effectively migrate more of their
network from TDM circuits to packet-based traffic and realize the
benefits of true network convergence. With network operations and
management so simplified, this enables carriers to more aggressively
address new markets.”
