US 2013/0259472 A1 · METHOD AND NETWORK NODE FOR CONFIGURING A NETWORK FOR OPTIMIZED TRANSPORT OF PACKET TRAFFIC

Abstract

In order to configure a network for optimized transport of packet data traffic, a first packet node determines whether a traffic volume to be forwarded to a remote second packet node exceeds a predefined bypass threshold. If that is the case, the first packet node sends a bypass request towards the remote second packet node. An intermediate third packet node processes the request and determines, whether it locally has an interfering second bypass request and in this case, determines which of the two requests has a higher weight. The bypass request or, in case of an interfering second bypass request, the one with the higher weight, is then forwarded to the remote second packet node. Upon receipt thereof, the second packet node determines whether the received bypass request can be served. It that is the case, the bypass will be executed by sending a trigger to a service layer network to establish a bypass connection in accordance with the bypass request.

Dependent claims

A method of configuring a network for optimized transport of packet data traffic by dynamically creating an optical bypass between remote network nodes;

comprising
at a first packet node, determining whether a traffic volume to be forwarded to a remote second packet node exceeds a predefined bypass threshold;
if said traffic volume exceeds said bypass threshold, sending from said first packet node via an intermediate third packet node a bypass request towards said remote second packet node;
at said intermediate third packet node, processing said request and determining, whether said intermediate third packet node has an interfering second bypass request and if that is the case, which of the two requests has a higher weight;
forwarding either said bypass request or, in case of an interfering second bypass request, the one with the higher weight to said remote second packet node;
and
at said second packet node, determining whether said bypass request can be served and if so, triggering in a service layer network to establish a bypass connection in accordance with said bypass request.

4 more elements

A packet node, comprising a processing device for processing data packets to be forwarded and deciding based on address information contained in each data packet and locally stored routing information to which next hop to forward each data packet;

and at least one transport interface for connection to a network node of service layer network;
wherein said processing device is operable to determine whether a traffic volume to be forwarded to a remote second packet node exceeds a predefined bypass threshold;
and if so, to send a bypass request towards said remote second packet node;
said bypass request comprising a weight indicative of an amount of header processing the requested bypass, when established in said service layer network, would save at intermediate packet nodes.
