US 9,178,806 B2 · High-speed content routing

Abstract

Various exemplary embodiments relate to a method and related network node including one or more of the following: receiving, at a first input line card of the network device, a message, the message including a destination address; transmitting the message, by the first input line card, to the second input line card based on the determination that the second input line card is configured with routing information related to the destination address; determining, by the second input line card and based on the routing information related to the destination address, that the message should be forwarded via a first output line card of the network device to another network device; transmitting the message, by the second input line card, to the first output line card based on the determination that the message should be forwarded; and transmitting the message, by the first output line card, to another network device.

Dependent claims

A method performed by a network device for forwarding a message, the method comprising:

receiving, at a first input line card of the network device, a message to be forwarded toward a destination, the message including a destination address;
determining, by the first input line card, that a second input line card of the network device is configured with routing information related to the destination address;
transmitting the message, by the first input line card, to the second input line card based on the determination that the second input line card is configured with routing information related to the destination address;
determining, by the second input line card and based on the routing information related to the destination address, that the message should be forwarded via a first output line card of the network device to another network device;
transmitting the message, by the second input line card, to the first output line card based on the determination that the message should be forwarded via a first output line card of the network device to another network device;
and
transmitting the message, by the first output line card, to another network device.

4 more elements

A network device for forwarding a message, the network device comprising:

a first input line card that stores a first set of forwarding information;
and
a second input line card that stores a second set of forwarding information different from the first set of forwarding information,
wherein the first input line card is configured to:
receive a message to be forwarded toward a destination, the message including a destination address,
determine that the second input line card is configured with routing information related to the destination address, and
transfer the message to the second input line card based on the determination that the second input line card is configured with routing information related to the destination address,
wherein the second input line card is configured to
determine, based on the second set of forwarding information, that the message should be forwarded via an output line card,
forward the message to the output line card based on the determination that the message should be forwarded via the output line card, and
wherein the output line card is configured to transmit the message to another network device.
