Systems and methods, consistent with the present invention, provide a
high-speed line interface for networking devices. Such an interface may
be used in networking devices, such as routers and switches, for
receiving data from, and transmitting data to, high-speed links, such as
those lines carrying data at rates of 2.5 Gbit/sec, 10 Gbit/sec, and 40
Gbit/sec and more. In a preferred embodiment, the interface deserializes
data from an incoming data stream onto a multi-line bus so that the data
may be processed at a lower clock speed. Packets are extracted from the
data on the multi-line bus and distributed among a plurality of
switching/forwarding modules for processing.
