Problems solved by technology

[0007] At present, the existing mobility scheme based on LISP protocol does not solve the problems of large delay in the registration process of the mobile node and more packet loss in the handover process.

Embodiment Construction

[0025] A non-limiting embodiment is given below in conjunction with the accompanying drawings to further illustrate the present invention.

[0026] The present invention provides a location identification switching method for intra-domain and inter-domain switching, including:

[0027] When the node MN enters a new network, it receives a notification from an access router, and the notification includes the identifiers of the Map Server and the gateway router.

[0028] If the ID of the advertised Map Server is the same as the ID of the last advertised Map Server, but the ID of the access router is different, it indicates that an intra-domain handover occurs. The uplink notification is the notification when the mobile node accesses the network last time, and the mobile node stores the notification identifier of the last network access.

[0029] When an intra-domain handover occurs, the handover uses a fast handover mechanism.

[0030] When the MN moves, it constantly detects t...

Abstract

The invention discloses a mobile node switching method based on a locator and identifier separation protocol. The mobile switching process is divided into intra-domain switching and inter-domain switching. A rapid switching mechanism is adopted for intra-domain switching, an enhanced cache management rapid switching mechanism is adopted for inter-domain switching, MNs (mobile nodes) send identifications to an ingress router, an EID (electronic identification) and the ingress router form a routing locator and identifier mapping relation, and the ingress router sends the mapping relation to a mapping server for storage. By the mobile node switching method, packet loss and time delay in the switching process can be obviously reduced.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a LISP (Locator / ID Separation Protocol, location identification separation protocol) mobile node switching method. Background technique [0002] In the traditional Internet architecture, the IP address is used not only as a node's location identifier but also as a node's identity identifier. When a node changes its IP address, the transport layer connection is interrupted and needs to be re-established. Therefore, the traditional Internet architecture is difficult to support node mobility. [0003] At present, IETF (Internet Engineering Task Force, Internet Engineering Task Force) proposes an idea of ​​LISP (Locator / ID Separation Protocol, Location Identification Separation Protocol) to solve current Internet problems. The problem of mobility support is solved by introducing the concepts of Locator and Identifier to represent location and node identifier respectiv...
