Abstract
A network processing device includes multiple control processors or applications. One or more of the multiple processors generates an address resolution request. A network interface is adapted to detect a reply to the address resolution request and broadcast the detected address resolution reply to the multiple control processors in the network processing device.
Claims19
A network processing device, comprising:
- packet processing circuitry adapted to receive an address request from any one of multiple processors in the network processing device, the packet processing circuitry adapted to output the address request to a network and to receive an address reply to the address request;
- and
- the packet processing circuitry adapted to multicast the address reply to multiple ones of the processors at the same time.
A method for updating addresses, comprising:
- sending the packet out with the first address to another network device;
- receiving an address request from one or more of the applications or processors for a second address associated with the first address;
- sending the address request over a network;
- receiving an address reply from the network identifying the second address associated with the first address;
- and
- broadcasting the address reply to multiple ones of the applications or processors at the same time.
3 more elements
A network processing device, comprising:
- multiple processors for controlling operations in the network processing device;
- and
- packet processing circuitry adapted to detect unicast control packets from a network and convert a detected unicast control packet into a multicast control packet that is relayed in parallel to the multiple processors at the same time.
