Abstract: A method and an apparatus for cross-service-zone communication, and a data center network. When a first virtual machine in a server sends a packet to a second virtual machine, the server determines, through searching, whether a routing table of a tenant to which the first virtual machine belongs exists on the server; when the routing table of the tenant to which the first virtual machine belongs does not exist on the server, send the packet to a gateway; receive the routing table of the tenant to which the first virtual machine belongs sent by the gateway through a service zone manager; and forward a subsequent packet of the first virtual machine according to the routing table; where the first virtual machine and the second virtual machine are located in different service zones.

Abstract translation: 一种用于跨服务区域通信的方法和装置，以及数据中心网络。 当服务器中的第一虚拟机向第二虚拟机发送分组时，服务器通过搜索确定服务器上是否存在第一虚拟机所属租户的路由表; 当第一个虚拟机所属租户的路由表不存在于服务器上时，将数据包发送到网关; 接收由网关通过服务区域管理器发送的第一虚拟机所属租户的路由表; 并根据路由表转发第一虚拟机的后续分组; 其中第一虚拟机和第二虚拟机位于不同的服务区域中。
