Forwarding Engine for MPLS LER using Programmable Ethernet Packet Processors

摘要

As the amount of Internet traffic is dramatically increasing, the forwarding engine becomes a bottleneck for an label edge router in MPLS network to process IP datagram. We design and implement a forwarding engine to process IP traffic through ATM Layer using programmable ethernet packet processors. The performance of the forwarding engine is enhanced by reducing the number of instruction on processing IP packets and amount of overhead on looping IP packet back in an ethernet packet processor.
