Packet traffic class prioritization method for telecommunication network, involves providing error signal to nodes and transmitting classes of real time and fail-safe and best effort and fail-safe with high priority in error operation

摘要

The method involves assigning packets to traffic classes of real time and fail-safe, real time and non fail-safe, best effort and fail-safe and best effort and non fail-safe. The classes are coded in an internet protocol (IP) header. The classes of real time and fail-safe and real time and non fail-safe are subjected to access control and are transmitted with high priority in error-free operation of a network. An error signal is provided to nodes of the network, and the classes of real time and fail safe and best effort and fail-safe are transmitted with high priority in case of error operation.
