Abstract:
An internetworking device which connects a first network to a second network through a transport network that conforms to SONET or SDH standards, the transport network being assigned a predetermined amount of SONET or SDH path resources, the internetworking device comprising:network interface means for providing a communication interface to link with the first network; traffic monitoring means for monitoring data traffic from the first network to the second network; bandwidth resource information storage means for storing information on path resources of the transport network; bandwidth allocating means for dynamically increasing bandwidth of the transport network by allocating an additional path to the transport network, consulting said bandwidth resource information storage means, when said traffic monitoring means detects increasing data traffic from the first network; and communication control means for controlling data transport from the first network to the second network using the increased bandwidth of the transport network.
