METHOD, DEVICE, AND SYSTEM FOR PACKET ROUTING IN A NETWORK

摘要

A method for distributed routing of a packet in a network is provided. The network includes a controller, a first server, a second server, and a first switch. The method includes: obtaining identifiers of the two servers in the network and network connection information; determining whether the two servers are in two different subnets of the network and whether the two different subnets are configured on a same router according to the identifiers of the two servers and the network connection information of the two servers; when it is determined that that the two servers are in two different subnets of the network and the two different subnets are configured on a same router, instructing the first switch to modify a packet header of a packet sent by the first server to the second server and forward the modified packet to the second server.

1. A method for packet routing in a network, comprising:
obtaining, by a controller, identifiers of two servers in the network and network connection information of the two servers; determining, by the controller, whether the two servers are in two different subnets of the network and whether the two different subnets are configured on a same router according to the identifiers of the two servers and the network connection information of the two servers; when it is determined that the two servers are in two different subnets of the network and the two different subnets are configured on a same router, instructing, by the controller, a first switch to: modify a packet header of a packet sent by a first server to a second server and forward the modified packet to the second server; wherein the network comprises the controller, the two servers, and the first switch, and wherein the two servers comprise the first server and the second server, the controller is connected to the first switch, the first server is directly connected to the first switch, the first server belongs to a first subnet of the network, and the second server belongs to a second subnet of the network.
