Problems solved by technology

[0004] 1. After the active / standby device switchover of the MS or the restart of the active MS, the registration information in the MS is lost, and the MS can only passively wait for the ETR to re-register, otherwise the corresponding protocol work cannot be completed;
[0005] 2. The MS lacks a mechanism to notify the ETR of re-registration. ETR cannot perceive the change of the MS status and can only rely on the periodic registration of the ETR. The registration period of the ETR is 1 minute, which takes a long time, resulting in a prolonged MS data recovery time ;
[0006] 3. During the recovery of the MS data, due to the lack of EID registration information, the Map-Request mapping request message cannot be processed and forwarded normally, resulting in the ITR not being able to request the Map-Cache entry for a long time, and unable to communicate with the remote LISP site

Embodiment Construction

[0033] The technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Apparently, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, other embodiments obtained by those skilled in the art all belong to the protection scope of this application.

[0034] LISP is a network construction idea that separates location and identification, forming two independent address spaces EID and RLOC (Routing Locator, routing location address), EID is the host address of the communication endpoint, used to identify the identity of the host, and RLOC is the LISP router The address can be routed and forwarded in the Internet, can be routed globally, and can be aggregated according to the network topology. Communication packets between EIDs are encapsulated by LISP according to the route of the Map-Cache mapping table entries, and f...

Abstract

The invention discloses a quick recovery method for an MS server. The quick recovery method is used in an LISP network. After the MS server undergoes main and standby switching, a standby MS server becomes a main MS server or the MS server reboots. The quick recovery method comprises the steps that: the MS server sends re-registered notification messages to site equipment according to prestored basic routing information of EID; the MS server receives registration messages sent by the site equipment according to the notification messages; and the MS server updates registration information of the EID according to the received registration messages, so as to complement the registration information of each EID. The quick recovery method and the quick recovery equipment achieve the purposes of notifying the target side equipment to re-register and recovering data quickly according to the basic routing information of the EID prestored in the MS server.

Description

technical field [0001] The present application relates to the field of network technology, in particular to a method and device for quick restoration of an MS server. Background technique [0002] When the existing communication between sites is performed based on LISP (Locator Identity Separation Protocol, location and identification separation protocol), the ETR (Engress Tunnel Router, tunnel router) in the site equipment periodically registers the Map-Register message to MS (Map-Server, mapping server) registers local EID (EndPoint Identifiers, communication terminal) routing information, after described MS receives the mapping request Map-Request message that site equipment sends, described MS will according to the registration information of EID The mapping request Map-Request packet is forwarded to the ETR of the destination site device. [0003] In the process of implementing the present application, the inventor found that the prior art has at least the following pr...
