Abstract: A method implemented in a node to forward data packets via a communication link to another node. The method includes receiving an indication of a resource level associated with one or more ports among the other node's ingress and egress ports. The indication to be received via a side-band communication link coupled to the other node. The method further includes forwarding one or more data packets associated with data to the other node based on the indicated resource level received via the side-band communication link.

Abstract: A method includes storing an address in an entry of a first memory device that is accessible by an address manager while the address is being stored in an entry of a second memory device included in a packet-forwarding device.

Abstract: An address lookup device provides information for a lookup value. A lookup value based on a network address in a received packet is received by a discriminant bits search device. A discriminant bits pattern is used to determine a location in an address lookup table based on the lookup value. The discriminant bits search device determines whether the lookup value is located in the location in the address lookup table. The discriminant bits search device outputs next hop information if the lookup value is located in the location in the address lookup table, and outputs default information if the lookup value is not located in the location in the address lookup table.

Abstract: A lookup table is modified by either the insertion or deletion of an address. A lookup table modification device receives an update instruction and determines a selected memory section of the lookup table and an address to which the update instruction relates. The selected memory section is updated. The lookup table modification device determines succeeding non-selected memory sections to which the update instruction does not relate, and modifies contents of one address in each of the succeeding non-selected memory sections. The lookup table modification device changes the logical origin of each of the succeeding non-selected memory sections.
