A mobile network-based tenant network service implementation method and system and network elements are disclosed. The method includes: an MME of a mobile network performing identity authentication of a tenant network to which UE belongs on the UE; after the UE passes the identity authentication of tenant network, the MME selecting a local exchange node for the UE; the MME transmitting a creation/update message of a local exchange forwarding table to the local exchange node; the local exchange node creating or updating the local exchange forwarding table and generating a forwarding table entry of UE, wherein the forwarding table entry comprises identification information of UE; after UE bearers establishment are completed, the local exchange node writing UE bearer information into the forwarding table entry of UE; and the local exchange node implementing message forwarding of the tenant network according to the local forwarding table, thereby implementing a tenant network service.

Mobile network-based tenant network service implementation method, system, and network element

A virtual network (VN) realization method and system are provided. The method includes setting a VN-AP in a data center network and/or a broadband network. A service deployment and management function entity receives a VN service request from a user to generate feature information of the VN; a PC/VM automatically discovers the VN-AP, the automatically discovered VN-AP generates the VN forwarding table entry of the PC/VM after the PC/VM passes the identity authentication of the VN, and performs tunnel encapsulation according to the VN forwarding table entry to forward a packet from the PC/VM. By discovering a VN-AP for processing a VN automatically, the disclosure realizes the automatic and rapid deployment of the VN.

Method and system for realizing virtual network

A virtual network auto-discovery and auto-configuration method and device thereof are provided. The method includes a tenant end system automatically discovering network virtualization edges (NVEs), the NVE initiating a VN identity authentication of the tenant end system, and the NVE automatically configuring a VN forwarding table of the VN after the tenant end system passes the VN identity authentication. The method and device solve the technical problem that virtual network configuration efficiency is low due to manually configuring the virtual network, and achieve the technical effect of improving the virtual network configuration efficiency.

Method and device thereof for automatically finding and configuring virtual network

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 (S); after receiving the IP address request message, the network side returns the non-IP-address EID of the terminal (S); the terminal uses the received EID as the address to transmit and receive packets (S). With this disclosure, the demands of the broadband network on the IP address are reduced.

Broadband network system and implementation method thereof

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.
