ABSTRACT:
Data transmission system for transmitting packets of data from a source workstation (10) to a destination workstation (40) wherein the packets of data are transmitted over at least a first IP network (14) and a second IP network (30) between an ingress node (20) connected to the source workstation in the first network and an egress node (38) connected to the destination workstation in the second network. The system comprises a local reservation server (26) in the first network accessible by the source workstation and a remote reservation server (42) in the second network accessible by the local reservation server. The local reservation server includes connection setup means for setting up a virtual connection meeting a predefined requirement of Quality of Service from the ingress node to the egress node in response to a request from the source workstation and bandwidth request means for requesting additional bandwidth in the second network to the remote reservation server.
