Control of data flows over transport networks

摘要

A method of preparing data packets for transport over a telecommunications transport network is disclosed. The data packets relate to different ones of a plurality of services. The method includes inspecting each of the data packets to identify the service to which the data packet relates. The identified service of the packet is mapped to a Quality of Service (QoS) type. A bandwidth profiling scheme is applied to the data packets, the profiling scheme identifying and marking each data packet according to whether or not the data packet conforms with a predetermined committed information rate for the QoS type. The marked data packets are forwarded for transport through the transport network. Related devices are also disclosed.

1. A method of preparing data packets for transport over a telecommunications transport network, wherein the data packets relate to different ones of a plurality of services, the method being implemented by a first network node and comprising:
inspecting each of the data packets within a given bearer that includes data packets for multiple services, wherein the inspecting comprises, for each of the data packets, identifying the service to which the data packet relates; mapping the identified service of each data packet to a Quality of Service (QoS) type; applying a bandwidth profiling scheme to the data packets, the profiling scheme identifying and marking each data packet according to whether or not the data packet conforms with a predetermined committed information rate (CIR) for the QoS type of its identified service; and forwarding the marked data packets in a single bearer for transport through the transport network, thereby enabling a second network node that is different from the first network node to selectively drop data packets at the transport network that do not conform with their associated CIR based on the marking.
