| 摘要 |
The invention comprises a method and a system for peer-to peer communication in an aggregation network, said network having end user devices (D 1,D2), said end user devices capable of acting as a source device and/or a target device, each connected via an access node (AN1, AN2,...) to said network (10), a gateway (30) for communication outside (30) of said network. Use is made of a Downstream ARP proxy, and a respective ARP Cache in several of the access nodes (D1, D2), and where the Downstream ARP proxy of said nodes on interception of an Downstream ARP request for a target end device controls whether said target device is present in the ARP Cache, and wherein an ARP reply giving the MAC address of the target device if present is sent, and if not present no ARP reply is sent. The invention further comprises the use of an enhanced upstream ARP proxy. |
