Abstract:
1. A method for switching from an established media path to a new media path for packets transmitted between first and second end points in a packet based network, the method comprising: transmitting, by a network element, an instruction to the second end point instructing it to set up a new receiving channel for receiving packets transmitted from the first end point over the new media path; transmitting, by the network element, an instruction to the first end point instructing it to configure a sending channel to send packets over the new media path for reception on the new receiving channel of the second end point; wherein the first endpoint, after being informed by the network element that the new receiving channel is setup, reconfigures the sending channel to begin sending packets over the new media path for reception on the new receiving channel of the second end point to remove the network element from a media path between the first and second end points; and wherein for a time period, the second end point monitors for packets simultaneously on both its new receiving channel and an established receiving channel configured to receive packets transmitted from the first end point over the established media path.
