Abstract: Embodiments of the present disclosure provide a resource allocation method, a packet communication method, and an apparatus. The resource allocation method includes: dividing, by a controller, a cloud data center network into multiple independent logical zones; allocating a corresponding tunnel label range to each logical zone; when a virtual network request for allocating a resource to a tenant is received, searching the logical zones to obtain a logical zone that meets the virtual network request; and allocating a tunnel label to the tenant according to a tunnel label range corresponding to the logical zone that meets the virtual network request. Because each logical zone is independent, during tunnel label range allocation, a same tunnel label range can be allocated to different logical zones. In this way, a same tunnel label can be allocated to different switches in different logical zones, implementing reuse of the tunnel label.

Abstract translation: 本公开的实施例提供资源分配方法，分组通信方法和装置。 资源分配方法包括：由控制器将云数据中心网划分成多个独立的逻辑区; 向每个逻辑区域分配相应的隧道标签范围; 当接收到向租户分配资源的虚拟网络请求时，搜索逻辑区域以获得满足虚拟网络请求的逻辑区域; 并根据与满足虚拟网络请求的逻辑区域相对应的隧道标签范围向租户分配隧道标签。 由于每个逻辑区域是独立的，在隧道标签范围分配期间，相同的隧道标签范围可以分配给不同的逻辑区域。 这样，可以在不同逻辑区域中的不同交换机上分配相同的隧道标签，实现隧道标签的重用。
