Updating networks with migration information for a virtual machine

A computer program product comprising:

• a computer readable storage medium readable by one or more processor and storing instructions for execution by the one or more processor for performing a method comprising:
• updating, by the one or more processor, a source network with migration information of a virtual machine to redirect network traffic for the virtual machine to a destination network;
• and
• providing, by the one or more processor, at least one remote network with virtual machine migration information, wherein the providing comprises providing the at least one remote network with the migration information of the virtual machine, wherein a plurality of clients of the at least one remote network are currently connected to the virtual machine, and wherein the providing comprises providing migration information to a limited subset of the plurality of clients currently connected to the virtual machine so that clients of the plurality of clients other than the limited subset of the plurality of clients are allowed to drop traffic.

A network authority device comprising:

• a memory;
• and
• one or more processor in communication with the memory, wherein the network device is configured to perform a method, the method comprising:
• updating, by the one or more processor, a source network with migration information of a virtual machine to redirect network traffic for the virtual machine to a destination network;
• and
• providing, by the one or more processor, at least one remote network with virtual machine migration information, wherein the providing comprises providing the at least one remote network with the migration information of the virtual machine within a time interval, the time interval selected to reduce redirecting of network traffic by the source network, wherein a plurality of clients of the at least one remote network are currently connected to the virtual machine, and wherein the providing comprises providing migration information to a limited subset of the plurality of clients currently connected to the virtual machine so that clients of the plurality of clients other than the limited subset of the plurality of clients are allowed to drop traffic.
