Abstract: This disclosure discloses a broadband network system and an implementation method thereof. The method comprises the steps that: a terminal transmits an IP address request message to the network side (S10); after receiving the IP address request message, the network side returns the non-IP-address EID of the terminal (S20); the terminal uses the received EID as the address to transmit and receive packets (S30). With this disclosure, the demands of the broadband network on the IP address are reduced.

Abstract: A method for implementing Identity and Locator Split is provided. The method is applied in a MPLS network. ITR and ETR are also LERs in the MPLS network. The method includes: establishing a point to point LSP tunnel between ITR and ETR by running a MPLS signaling protocol; the ITR storing an EID of endpoint and RLOC mapping as well as a RLOC and outer MPLS label mapping, and forwarding the endpoint's data packets in the MPLS network based on the outer MPLS label corresponding to the RLOC. A data encapsulation method for Identity and Locator Split and a LER device in the Identity and Locator Split network are also provided in the present invention. The present invention greatly improves the encapsulation and transmission efficiency of LISP data packets in the MPLS network.

Abstract: The invention discloses a system for network deployment and a method for mapping and data forwarding thereof. The system for network deployment comprises Distributed Hash Table (DHT) servers and DHT border servers, wherein at least one DHT border server and one DHT server are connected to form a server ring which constitutes a distributed mapping database used for storing a mapping relationship between Endpoint Identifiers (EIDs) and Routing Locators (RLOCs), and the server rings are connected with each other through the DHT border servers, wherein the DHT border server is configured to notify the EID prefix information in a present server ring to other server rings and monitor the DHT messages of the distributed mapping database. By the present invention, the network deployment and cross-domain data forwarding based on the DHT are achieved.
