Topology Discovery in a Computing System

摘要

A computer network may comprise a plurality of computing devices. In one example, a method may be provided for discovering topology of the computer network. The method may comprise sending, by a host computing device of the computing network, a neighbor discovery packet to each network interface of the host that has a connection, receiving a reply packet responding to the neighbor discovery packet, building a neighbor map for all neighbor computing devices to the host, sending a connection discovery packet to each network interface of the host that has a connection, receiving reply packets responding to the connection discovery packet, and building a connection map for connections among computing devices based on the information in the reply packets.

1. A method for discovering topology of a computer network that has a plurality of computing devices, comprising:
sending, by a host of the computing network, a neighbor discovery packet to each network interface of a plurality of network interfaces, including sending a first neighbor discovery packet to a first network interface; receiving a first neighbor discovery reply packet responsive to the first neighbor discovery packet; building a neighbor map for all neighbor computing devices to the host using the first neighbor discovery reply packet; sending a connection discovery packet to each network interface of the host that has a connection, including sending a first connection discovery packet to the first network interface; receiving a first connection discovery reply packet responsive to the first connection discovery packet; and building a connection map for connections among computing devices using the information in the first connection discovery reply packet.
