Abstract: An embodiment method of loop suppression in a layer-two transit network with multiprotocol label switching (MPLS) encapsulation includes receiving a packet at a provider edge (PE) router for the layer-two transit network. The packet is stored in a non-transitory memory on the PE router. The packet is stored according to a packet data structure having an MPLS label field and a layer-two header. A time-to-live (TTL) attribute is then determined for the packet. The TTL attribute is written to the non-transitory memory in the MPLS label field. The packet is then routed according to information in the layer-two header.

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: A service description may be used in network virtualization in order to specify requirements of an application. In order to provide network virtualization for generic networking components, including legacy networking components, the service description is mapped to a logical network implementation and then subsequently mapped to a physical implementation.
