WebbFor example, a 1-Gb/s Ethernet interface can deliver anywhere between 81,274 and 1,488,096 p/s. By comparison, a 10-Gb/s Ethernet interface can deliver packets at 10 times these rates– between 812,740 and 14,880,960 p/s. That is, a 10x change in bandwidth (b/s) has the same 10X change in packet rate (p/s). Other Performance Metric Relationships WebbShared memory packet interface (memif) library.

WebbRouter Interface Queues. In most cases, switches and routers are configured for "best-effort" packet forwarding. This means that the router forwards all packets it receives to the best of its ability. The router forwards a packet as soon as it can perform the table lookup necessary to determine the appropriate egress interface(es) for the packet.
