Problems solved by technology

[0004] In the LISP network, when a virtual machine migration occurs, the xTR that first detects the virtual machine migration event notifies other xTRs in the data center of the virtual machine migration event by multicasting three map notification (map notify) messages. Therefore, when When the data center has a new online xTR after the virtual machine migration event, the new online xTR will not be aware of the virtual machine migration, resulting in traffic failure

Embodiment Construction

[0022] figure 1 It is a schematic diagram of a processing process when a virtual machine migration event occurs in a LISP network.

[0023] Such as figure 1 As shown, when the virtual machine VMB is migrated from data center 1 (DataCenter1, DC1) to data center 2 (DataCenter2, DC2), the processing process includes the following steps:

[0024] Step 101, after the virtual machine VMB is migrated from DC1 to DC2, it sends a data packet.

[0025] In step 102, xTR2 of DC2 receives the data message of VMB, thus detecting that the virtual machine VMB migrates in.

[0026] Step 103, after xTR2 detects that the VMB has migrated in, it will issue a 32-bit VMB host route, and register the 32-bit host route 10.17.1.65 / 32 of the migrated VMB with MS / MR.

[0027] Step 103, xTR2 sends a multicast map notify to notify other xTRs that the virtual machine has been migrated in, and the multicast map notify will be retransmitted 3 times.

[0028] Such as figure 1 As shown, there are currentl...

Abstract

The invention discloses an information processing method and device for virtual machine migration in an LISP (locator identity separation protocol) network. The method comprises steps as follows: when an online TR (tunnel router) detects virtual machine migration, whether the online TR firstly learns information of virtual machine migration or not is judged, and identity information is set in a virtual machine migration routing list and used for recording a judgment result; the online TR receives an online notification message which is sent by another online TR online; the online TR inquires the virtual machine migration routing list, screens out the firstly learned information of virtual machine migration according to the identity information in the virtual machine migration routing list, carries the firstly learned information of virtual machine migration in an online notification response message and feeds back the online notification response message. With the application of the method and the device, the problem of blocked flow due to the fact that a new online xTR cannot perceive virtual machine migration after virtual machine migration can be solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for processing virtual machine migration information in a LISP network. Background technique [0002] Locator Identity Separation Protocol (LISP) is a network construction idea that separates location and identity. LISP network forms two independent address spaces, namely Endpoint Identifier (EID) space and Router Location (Routing Locator, RLOC) space. Wherein, EID is the host address of the communication endpoint, which is used to identify the identity of the host. In the LISP network, EID can be migrated independently of RLOC; the EID address of the migrating host remains unchanged during the migration process. RLOC is the address of the LISP router, which can be routed and forwarded in the existing Internet. The packets communicated between EIDs are encapsulated by LISP according to the LISP map cache (Map Cache) route, and the packets are forwar...
