Abstract
A method, system and apparatus for routing of data transmitted from a mobile electronic device to a first host of a plurality of hosts in a communication network using a Border Gateway Protocol (BGP) is provided. It is determined, at a network element having a same address as a first host of a plurality of network hosts, that the first host has failed via receipt of BGP (Border Gateway Protocol) rerouted data, the BGP rerouted data originally transmitted to the first host from a communication device. A negative acknowledgement (NACK), identifiable as having been transmitted by the network element, is transmitted to the communication device to trigger the communication device to transmit data that was to be transmitted to the first host to another of the plurality of network hosts.
