1. one kind use in the data center with tenant for carrying out route internet protocol version four (IPv4) method of dividing into groups as IPv6 grouping on IPv 6 (IPv6) network, described internet protocol version four (IPv4) grouping has pay(useful) load and comprises the header of IPv4 source and destination way address, and described IPv6 grouping has header and pay(useful) load, described method comprises:

  • -the IPv4 received from the first virtual machine associated with the first tenant divides into groups, and described IPv4 grouping is addressed to the second virtual machine associated with the second tenant;

    -generating the header that described IPv6 divides into groups, the header of described IPv6 grouping comprises the IPv6 address determined by one of them the application reversible transformation to following item;

    The combination of the identifier of described IPv4 source address and described first tenant, andThe combination of the identifier of described IPv4 destination-address and described second tenant;

    -based on receive IPv4 grouping pay(useful) load generate described IPv6 divide into groups pay(useful) load;

    -assembling to generate described IPv6 by pay(useful) load of being divided into groups by generated IPv6 with the IPv6 packet header generated divides into groups;

    And-on described IPv6 network by generated IPv6 grouping queries to described second virtual machine.
