BROADBAND NETWORK ACCESS

摘要

A method and Access Network Node (15) for handling dissimilar protocols when a Host (11) accesses a Broadband Network. The Access Network Node includes a protocol converter (37) for interworking between the Neighbor Discovery, ND, protocol and the Dynamic Host Configuration Protocol, DHCP. When an ND Router Solicitation message (21) is received from a Host that does not support DHCP, the converter converts the ND message to a DHCP Solicit message (22) and forwards it to a Broadband Network Gateway, BNG, (14) together with a port ID. When the Access Network Node receives a DHCP Reply message (25) from the BNG destined for the same Host (11), the converter converts the DHCP Reply message to an ND Router Advertisement message (26) before sending it to the Host.
