COMPUTER IMPLEMENTED METHOD, A SYSTEM AND COMPUTER PROGRAMS FOR CONGESTION CONTROL IN A TRANSPORT NODE OF A COMMUNICATION NETWORK

摘要

The method comprises identifying and classifying, by a classification unit (102), received data packets flows between fixed bit rate data packets flows (FB) and variable bit rate data packets flows (VB); sending the identified and classified fixed bit rate data packets flows (FB) to a pacer unit (103) spacing the transmission of the fixed bit rate data packets flows (FB) towards an egress port of the transport node (100); and sending the configuration parameters relating to the variable bit rate data packets flows (VB) to a virtual queue unit (104), said virtual queue unit (104) including a processor running an algorithm to activate one or more congestion correction procedures, wherein in case the result obtained by said algorithm being over, or equal, at least one threshold activating a corresponding congestion correction procedure.

1. A computer implemented method for congestion control in a transport node of a communication network, the method comprising:
identifying and classifying, by a classification unit (102), received data packets flows between fixed bit rate data packets flows (FB) and variable bit rate data packets flows (VB), said classification being performed upon the classification unit (102) having checked a plurality of configuration parameters concerning the data packets flows; sending the identified and classified fixed bit rate data packets flows (FB) to a pacer unit (103) spacing the transmission of the fixed bit rate data packets flows (FB) towards an egress port of the transport node (100); and sending the plurality of configuration parameters relating to the identified and classified variable bit rate data packets flows (VB) to a virtual queue unit (104), said virtual queue unit (104) including a processor running an algorithm to activate one or more congestion correction procedures, wherein in case the result obtained by said algorithm being over, or equal, at least one threshold activating a corresponding congestion correction procedure.
