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.
