Abstract

The invention discloses an interconnection method of IPoA and IPoE, wherein at the ascending direction of IPoA-IPoE conversion, a wideband access device recombines an ATM signal unit received from user interface into an IP report, processes MAC package on the IP report, adds a virtual local network mark, and sends an Ethernet data pack to network interface, and at the descending direction of IPoE-IPoA conversion, the wideband access device receives an Ethernet data pack from network interface, based on a virtual local network mark searches a transfer list, judges that the Ethernet data pack is not ARP pack, extracts an IP pack transparently, uses an ATM SAR module to process the IP pack segmented into ATM signal units, and sends the ATM signal units to user interface, and answers the ARP pack. The invention realizes the intercommunication between IPoA interface and IPoE interface, which can resolve the interconnection problem between prior ATM network and Ethernet.

Description

technical field

[0001] The invention relates to the technical field of network interfaces, in particular to a method for realizing the interconnection of IPoA and IPoE. Background technique

[0002] There are mainly two kinds of Gigabit Ethernet and ATM suitable for LAN backbone technology nowadays.

[0003] Gigabit Ethernet is one of the recognized technical development directions in the network industry. It is an extension of the successful 10Mbps and 100Mbps IEEE802.3 Ethernet standards. It still uses the Ethernet IEEE802.3 frame format, full-duplex operation and flow control method. . To sum up, the advantages of Gigabit Ethernet are: the network technology is reliable, easy to manage, and scalable, and its price level is much lower than that of ATM; the disadvantage is that some standards are not uniform.

[0004] ATM (Asynchronous Transfer Mode) is a fast packet switching technology widely used in telecommunication networks. It adopts fixed cell length and connection...
