Abstract: A method for packet routing in a network is disclosed. The network includes a network controller, a first switch connected to the network controller, a first server directly connected to the first switch, and a second server. The network controller obtains network connection information of the two servers. The network connection information indicates that the first server belongs to a first subnet and the second server belongs to a second subnet, the first subnet and the second subnet are two different subnets, and the two different subnets are configured on a same router. The network controller sends configuration information to the first switch. The configuration information configures the first switch to modify a packet header of a packet sent from the first server to the second server, and forward the modified packet to the second server.

Abstract: 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.

Abstract translation: 提供了一种用于网络中分组路由分发的方法。 网络包括控制器，第一服务器，第二服务器和第一交换机。 该方法包括：获取网络中的两台服务器的标识符和网络连接信息; 根据两台服务器的标识符和两台服务器的网络连接信息确定两台服务器是否在两个不同的网络子网中，以及两台不同的子网是否在相同的路由器上配置; 当确定两个服务器在网络的两个不同子网中并且两个不同的子网被配置在同一路由器上时，指示第一交换机将由第一服务器发送的分组的分组报头修改为第二服务器 并将修改的分组转发到第二服务器。
