TERAWAVE INTRODUCES HIGH DENSITY PON-BASED LAN-SWITCH MODULE.
VLANs form an important element of any IT group's administrative strategy. In today's highly mobile computing environment, employees are often required to connect into their company's network from remote sites. Also, cross-functional teaming requires many employees to be part of diverse departmental sub-networks at different moments in time. Terawave's VLAN implementations offer a solution for just this problem. By using Terawave's TW-300 LAN-Switch Module (LSM), tracking and ensuring zero downtime for a worker's connectivity is no longer a logistical nightmare for the IT department. The TW-300 LSMs can enable tracking of workstation movements without requiring manual reconfiguration of IP addresses, and also allow creation of closed user groups and broadcast domains.
Based on the IEEE's 802.1Q standard, Terawave's LSM is an elegant application of the TeraPON technology suite for VLAN scenarios. By marrying the bandwidth flexibility offered by Terawave's SALSA technology with VLAN functionality, the PON- based LSM solution can offer superior QoS performance and increased service options for the Service Provider. "The inherent burstiness of LAN traffic allows us to exploit statistical multiplexing across the entire GigaPON. Our SALSA technology ensures that a particular VLAN port has sufficient instantaneous bandwidth when required," states Don Stalter, vice president of marketing at Terawave Communications. The PON-based LSM allows VLAN definition by port groups and MAC addresses, and also supports the 802.1Q fully tagged frame formats, which enable port membership in multiple overlapping VLANs.
In addition, the PON-based LSM supports traffic filtering based on source and destination MAC addresses, using static and dynamic network address learning rules. This allows the Service Provider to create sophisticated Service Level Agreements (SLAs) in which traffic from certain subscribers can be preferentially treated over others. This enables service differentiation for performance based Quality of Service (QoS), as well as SLA policy based rules.
Finally, Terawave's PON-based LSM brings extremely low-cost, high-speed Internet access to the consumer by allowing LAN extension across local and wide-area networks. Terawave's LSM opens the road to commoditizing bandwidth hungry applications such as Internet based video services by eliminating the current bottlenecks associated with DSL technology. By using the ubiquitous LAN interface, specialized DSL modems are also eliminated.
