Distributed Coordination of Network Elements for Packet Encapsulation

摘要

In one embodiment, an encapsulator device receives a source stream of encoded packets in a first transport format and converts the source stream to packets of an output stream in a second transport format for communication over a data network. The encapsulator device generates a mapping stream with information indicating which packets in the source stream are used to generate the output stream. The output stream of the encapsulator device is coordinated with the output stream of other encapsulator devices by sending the mapping stream to the other encapsulator devices in the network. The other encapsulator devices use the mapping stream to generate identical output streams.

1. A method comprising:
at an encapsulator device, receiving a source stream of encoded packets in a first transport format; converting the encoded packets of the source stream to packets of an output stream in a second transport format for communication over a data network; generating a mapping stream that comprises information indicating which ones of the encoded packets of the source stream are used to generate the output stream; and coordinating the output stream with output streams of other encapsulator devices by sending the mapping stream to the other encapsulator devices in the network so that the other encapsulator devices can use the information in the mapping stream to generate identical output streams.
