Abstract(in English) | This paper proposes a scalable multi-QoS IP+ATM switch router architecture. The proposed switch router is based on a core ATM switching system with multi-QoS capability. Forwarding engines (FEs) and routing engine (RE) are attached in front of the line cards of the ATM switching system. FEs and RE are inter-connected with each other via internal VCs. A novel longest matching algorithm is employed at the FE to achieve wire-speed packet forwarding for a long network address like IPv6. Wire-speed unicast and multicast packet forwarding are implemented by using point-to-point (p-p) and point-to-multipoint (p-mp) VCs in a unified way. Bacause FEs and RE are decoupled from the base ATM switching system, full spectrum of ATM QoS capability is nicely applied for IP QoS control with a packet classification at the edge of the network. The core switching fabric is scalable from 40 Gb/s to 160 Gb/s capacity (371 MPPS in terms of packet forwarding throughput). An feedback rate control is employed at each line card to eliminate congestion in the high-speed core switching fabric, in which only small amount of buffer is feasible. |
