Plotting its next big market thrust, PMC-Sierra Inc. this week will roll out a chipset that promises to deliver the long-awaited convergence of LAN and WAN on the network.
The new Chess (Channelizer Engine for SONET/SDH) chipset supports a variety of network protocols-including ATM, Internet Protocol (IP), SONET/SDH, and others-in a single multiservice switch, router, or related system.
Designed to aggregate and manage network traffic running at transmission speeds up to OC-48, the Chess chipset is said to deliver a total throughput of more than 160 Gbits/s.
The chipset is also aimed at attacking the trouble spot on the WAN-the metropolitan-area network (MAN), according to Steve Perna, vice president and general manager of the Transmission Switching Division at PMC-Sierra, Burnaby, British Columbia.
In the MAN, as in the WAN, "carriers are also rapidly moving from OC-3 to OC-48 networks," Perna said. "What we've done is develop a chipset that addresses [the bandwidth bottlenecks] in the MAN."
The company is also developing products to address long-haul WAN applications, where carriers are migrating from OC-48 to OC-192. "In this space, we'll make an announcement in the near future," Perna said.
The Chess chipset was developed in order to design a single multiservice switch for the MAN, which, in theory, could replace a multitude of systems on the edge of the network, he added.
The chipset enables a system to take data from a network and then channelize, aggregate, and transform the traffic into a wide range of services at different speeds.
Chess consists of the Spectra-2488 and Spectra-4 X 155 framers; the S/UNI-MACH48 mapper; an STS-1 cross-connect chip, dubbed TSE; and the TBS backplane serializer. Using the Spectra family of framers enables network traffic to be channelized at smaller bandwidth increments, while the S/UNI MACH48 chips provide ATM and SONET mapping functions.
Another key chip is the TSE STS-1 cross-connect device, which provides a nonblocking, single-stage switch fabric. Supporting a number of line rates, the device delivers an aggregate bandwidth of up to 40 Gbits/s. Up to four TSEs can be cascaded for a total throughput of 160 Gbits/s.
Pricing is $395 for the Spectra-2488, $324 for the Spectra-4 ?? 155, $505 for the TSE, $396 for the S/UNI-MACH48, and $79 for the TBS.
The TBS and TSE chips are sampling, with the remaining products slated for production in the third quarter.
