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 that the first host has failed via receipt of BGP rerouted data at least one network element, the BGP rerouted data originally intended for the first host. A negative acknowledgement (NACK) is transmitted to the mobile electronic device from the at least one network element, the NACK enabled to trigger the mobile electronic device to transmit data that was to be transmitted to the first host to another of the plurality of hosts and wherein the NACK is identifiable by the mobile electronic device as having been transmitted by the at least one network element.
