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. |

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.”
