peer access
2.The concrete implications of the network interfusion and the ways to realize that are analyzed; the two possible methods of the integration of ATM(asynchronous transfer mode)and IP(internet protocol),the overlay method and the peer method,are discussed; and that the access network technique would possibly be the first to break through the barriers to the network interfusion and interconnection is infered.
3.Because Chord is a typical distributed structured peer-to-peer (P2P) system based on overlay network, the distance between two adjacent peers may be very far on IP network, and the network access speed is greatly reduced.
