A change in a client device is detected (306) during a transmission of a plurality of packets destined to at least one first destination used by at least one packet session. In response to the change, a determination (312) is made as to whether some but not all of the plurality of packets should be redirected to at least one second destination based, at least in part, on at least one predefined criterion. Accordingly, some but not all of the plurality of packets is redirected (316) to the at least one second destination when the some but not all of the plurality of packets should be redirected according to the at least one predefined criterion.

1. A method for data packet transmission on a network, the method comprising the steps of: detecting a change in a client device during a transmission of a plurality of packets destined to at least one first destination used by at least one packet session;responsive to the change in the client device, determining whether some but not all of the plurality of packets should be redirected to at least one second destination based, at least in part, on at least one predefined criteria;redirecting the some but not all of the plurality of packets that were destined to the at least one first destination, to the at least one second destination; andwhile redirecting the some but not all of the plurality of packets to the at least one second destination, continuing to redirect remaining packets of the plurality of packets that were destined to the at least one first destination and that are not the some but not all of the plurality of packets, to the at least one first destination. 2. The method according to claim 1, wherein the predefined criteria comprises any one or more selected from a group of movement of a device served by the client device out of the first destination, an instruction by a user of the client device, a connection of the client device to a new access network, loss of at least a portion of communication links, a detection of proximity of alternative terminal, change in client device usage of the at least one packet session, transfer sessions between the client device and another client device, and a reduction of power consumption. 3. The method according to claim 1, wherein the first destination comprises any one or more selected from a group of at least one Internet Protocol address, at least one label, at least one port, at least one flow identifier, at least one virtual circuit, and at least one frame header. 4. The method according to claim 1, wherein the second destination comprises any one or more selected from a group of at least one Internet Protocol address, at least one label, at least one port, at least one flow identifier, at least one virtual circuit, and at least one frame header, an analog input, an analog output, a digital input, and a digital output. 5. The method according to claim 1, wherein detecting the change in the client device further comprises: receiving an indication of the change from the client device. 6. The method according to claim 1 further comprising: receiving, by a network element, all of the plurality of packets destined to the at least one first destination used by the at least one packet session. 7. The method according to claim 1 further comprising: assessing the some but not all of the plurality of packets that should be redirected based, at least in part, on at least one predefined parameter. 8. The method according to claim 7, wherein the at least one predefined parameter is selected any or more from a group of at least one source Internet Protocol address, at least one source port identifier, at least one destination port identifier, a session indicator, a flow indicator, a transport protocol type, and a transport protocol session. 9. The method according to claim 1 further comprising: selecting the at least one second destination based, at least in part, on a predefined parameter. 10. The method according to claim 9, wherein the predefined parameter comprises any or more selected from a group of the second destination provided by the client device, the second destination provided by another client device, the second destination provided by a network infrastructure, a detection of the second destination assigned to the another client device, an assignment of the second destination as the location of the client device changes, and a request of a media conversion device. 11. The method according to claim 1, wherein redirecting the some but not all of the plurality of packets that were destined to the at least one first destination, to the at least one second destination further comprises: substituting the at least one first destination with the second destination. 12. The method according to claim 1, wherein redirecting the some but not all of the plurality of packets that were destined to the at least one first destination, to the at least one second destination further comprises: tunneling the some but not all of the plurality of packets that were destined to the at least one first destination, with the at least one second destination. 13. The method according to claim 1, wherein redirecting the some but not all of the plurality of packets that were destined to the at least one first destination, to the at least one second destination further comprises: duplicating the some but not all of the plurality of packets that were destined to the at least one first destination, using the at least one second destination. 14. A method for data packet transmission on a network, the method comprising the steps of: detecting a change in a client device during a transmission of a plurality of packets destined to at least one first destination used by at least one packet session;in response to detecting the change in the client device, redirecting all of the plurality of packets to a network element that: determines whether some but not all of the plurality of packets should be redirected to at least one second destination based, at least in part, on at least a predefined criteria, redirects the some but not all of the plurality of packets that were destined to the at least one first destination, to the at least one second destination, and while redirecting the some but not all of the plurality of packets to the at least one second destination, continuing to redirect remaining packets of the plurality of packets that were destined to the at least one first destination and that are not the some but not all of the plurality of packets, to the at least one first destination. 15. The method according to claim 14, wherein the at least one predefined criteria comprises any one or more selected from a group of movement of the client device out of the first destination, an instruction by a user of the client device, a connection to a new access network, loss of a communication tool, a detection of proximity of alternative terminal, change in client device usage of the at least one packet session, and transfer sessions between the client device and another client device. 16. An apparatus for data packet transmission on a network, the apparatus comprising: a controller circuit that detects a change in a client device during a transmission of a plurality of packets destined to at least one first destination used by at least one packet session, the controller circuit determines whether some but not all of the plurality of packets should be redirected to at least one second destination based, at least in part, on at least one predefined criteria;a transceiver circuit operably coupled to the controller circuit, wherein the transceiver circuit redirects the some but not all of the plurality of packets that were destined to the at least one first destination, to the at least one second destination and while redirecting the some but not all of the plurality of packets to the at least one second destination, continuing to redirect remaining packets of the plurality of packets that were destined to the at least one first destination and that are not the some but not all of the plurality of packets, to the at least one first destination.
