Abstract

The invention relates to the field of network communication in a wide area, where a local network of a first type has a sending station that communicates with a receiving station in a local network of a second type. A network of a third type is in between the two networks and provides virtual private networking between the two local networks. The network of the first type supports a fine grained QoS, whereas the network of the third type supports a coarser grained QoS. In one example the network of the first type is RSVP capable and the network of the second type is an MPLS network.The invention resides in a component called RSVP-MPLS proxy that maps the RSVP resource advertisements and reservations within an RSVP-aware customer network to an MPLS network, whereby the receiver side doesn't participate in the RSVP communication process.
