Data center networks

摘要

Measures for establishing connectivity in a data center network are provided. A virtual connection is created between a virtual system hosted on a server in a data center network, and a packet forwarding function in that server. Additionally, an entry is populated in a packet forwarding data store in the server, which includes an internet protocol (IP) address of the virtual system and an associated identifier for the created virtual connection. The packet forwarding data store is accessed by the packet forwarding function when making forwarding decisions for received data packets.
