Abstract
The present application discloses a method and system of sharing reserved bandwidth among several connections issuing from a same physical port in an origin node of a packet switching communication network comprising a plurality of nodes interconnected with transmission links. At each request for establishing a connection i from an origin node to a destination node, the dependent connection management process:selects for connection i a routing path comprising one or a plurality of links from the origin node to the destination node:identifies on the selected path all consecutive links starting from the origin node and shared with another connection issuing from the same physical port;reserves on each link of these identified consecutive links an aggregate bandwidth for all connections issuing from the same physical port, said aggregate bandwidth being less than the sum of the bandwidth reserved for each connection considered individually.
