10-Gbps Traffic Manager Solution
The value of bundling services is accelerating carrier investment in triple-play networks. Managing these (voice, video, and data) services on a common Internet protocol (IP) network leads to a dramatic reduction in operational expenses. In addition, this migration to IP networks enables carriers to offer enhanced services to drive increased revenues. These emerging services are the key to carrier growth and sustainability in the future. Supporting these future services requires a solution that meets today’s stringent quality of service (QoS) requirements, yet is flexible enough to adapt to tomorrow’s changing requirements.
Traffic Manager Solution Overview
Altera has a working 10-Gbps traffic manager solution (see Figure 1) targeting Stratix® II FPGAs. The inherent programmability of the FPGA allows the traffic manager to be adapted to support changing carrier requirements or emerging services. This traffic manager solution meets guaranteed line-rate performance for Ethernet, packet over SONET/SDH, multiprotocol label switching (MPLS), and Asynchronous Transfer Mode (ATM) traffic.

The ability to utilize individual modules, such as the scheduler, queue manager, policer, and memory controllers allows you to target the traffic manager to your specific application requirements. Figure 2 shows an example application for a GPON OLT card.

Demonstration Board
Altera built a traffic manager demonstration board (see Figure 3) to showcase the functionality of the solution. The demonstration board contains two Stratix II FPGAs, one serving as the traffic manager and the other as the traffic generator. The demonstration can exist in a stand-alone environment, or the traffic generator can be bypassed with external test equipment generating traffic. To find out more information about Altera’s traffic manager solution, contact your local Altera sales representative.
