Title: METHOD AND APPARATUS FOR IMPLEMENTING INTERWORKING BETWEEN VIRTUAL PRIVATE CLOUD NETWORK AND EXTERNAL NETWORK
Abstract:
A method and apparatus for implementing interworking between a virtual private cloud network and an external network. The method comprises: a virtual extensible local area network (Vxlan) gateway receives data from a router, finds a third flow entry and a fourth flow entry that correspond to the data from a first flow table, and searches in a network address translation (NAT) table for a NAT entry corresponding to the data according to the third flow entry; the Vxlan gateway sends the data to an external network according to the found NAT entry; the Vxlan gateway mirrors the data according to the fourth flow entry; the Vxlan gateway searches in a second flow table for a fifth flow entry corresponding to the mirrored data, searches in a NAT rule table for a NAT entry corresponding to the mirrored data according to the found flow entry, and delivers the found NAT entry to the NAT table.
