Abstract: The present application discloses a method and apparatus for establishing a virtual network communication link. A specific implementation of the method includes: determining no flow table being detected; and determining sending of a data packet according to information about the data packet. This implementation implements automatic flow table repair, ensures an SLA for a virtual network communication link, and improves the disaster tolerance capability of the communication link.

Abstract: The present application discloses a communication processing method and apparatus. A specific implementation of the method includes: receiving, through a tunnel bridge to a first physical machine, a packet sent from a virtual machine, the first physical machine being a host machine of the virtual machine; determining whether the packet is an Address Resolution Protocol (ARP) request packet, and obtaining a destination address of the packet; if the packet is the ARP request packet and a destination address of the packet is not an address of a virtual machine in the first physical machine, writing a predetermined pseudo physical address into an ARP response and returning the ARP response; and if the packet is not the ARP request packet, sending the packet to a terminal associated with the destination address of the packet. This implementation reduces load of network nodes.
