Network traffic from a central device across a communication link to a remote device is controlled based upon central traffic management resources in the central device. The central traffic management resources are coupled to a communication link and monitor data packets received across the communication link to learn characteristics of the remote network. Based on the learned characteristics, traffic management messages are generated in the central traffic management resources. These messages are forwarded to an interface device on the remote network, where traffic on the communication link is controlled in response to the traffic management messages. Thus, the remote interface is configured automatically by central traffic management resources running in the central device without human intervention at the remote network. The traffic management messages manage traffic across a communication link of two packets to be forwarded from the remote interface across the communication link. Second, traffic management messages identify types of packets to be composed by the remote interface for communication to users of the remote network. Thus, packages originating on the remote network are filtered so that only necessary packets are forwarded to the central site. Similarly, packets which normally originate from the central site are "spoofed" at the remote site in response to management messages generated at the central site. The central traffic management resources execute a transport protocol for the traffic management messages which are independent of a network address for the remote interface.
On contrôle le trafic de réseau entre un dispositif central et un dispositif éloigné par l'intermédiaire d'une liaison d'intercommunication en fonction de ressources de gestion du trafic centrales (60) dans le dispositif central. Les ressources de gestion de trafic centrales (60) sont couplées à une liaison d'intercommunication et surveillent les paquets de données reçus par l'intermédiaire de ladite liaison de manière à collecter des caractéristiques sur le réseau éloigné. En fonction de ces caractéristiques collectées, des messages de gestion de trafic sont générés dans les ressources de gestion de trafic centrales (60). Ces messages sont envoyés à un dispositif d'interface (67) sur le réseau éloigné, le trafic sur la liaison d'intercommunication étant modulé en réponse aux messages de gestion de trafic. Ainsi, l'interface éloignée (67) est configurée automatiquement par les ressources de gestion de trafic centrales (60) exploitées dans le dispositif central, sans intervention humaine au niveau du réseau éloigné.
