Embodiment 1

[0053] Embodiment 1 of the present invention provides a method for deploying logical nodes with a successor backup relationship, such as figure 1 shown, including:

[0054] Step 101, obtaining the logical node to be allocated and the physical node carrying the logical node;

[0055] Step 102, for any physical node carrying multiple logical nodes, configure the successor backup relationships of the multiple logical nodes carried on it to point to different physical nodes respectively.

[0056] After step 101, before step 102, also include:

[0057] Step 103, judging whether the relationship between the number of physical nodes and the number of logical nodes is satisfied: n≤m(m-1), wherein n is the number of logical nodes, and m is the number of physical nodes;

[0058] When the judgment result is satisfied, step 102 is executed.

[0059] The method also includes:

[0060] When the judgment result in step 103 is unsatisfactory, the logical nodes that do not have the success...

Embodiment 2

[0075] Embodiment 2 of the present invention provides a logical node deployment method, which is applied to figure 2 The system shown is described as an example, and the logical node is described by taking a virtual node as an example.

[0076] figure 2 The platform resource fusion architecture of China DSN is located at the infrastructure layer below the core function layer, including the DSN core function node management system, the DSN virtual resource management system and the joint strategy library:

[0077] Among them, the core function layer: includes several abstract telecommunication service capabilities (DSN distributed switching network, intelligent media routing and content switching network, etc.), and provides upward calling interfaces for various telecommunication application software. For example, voice services represented by VoIP, content sharing services represented by Streaming, etc. Each core function system uses distributed technology such as P2P to d...

Embodiment 3

[0109] Embodiment 3 of the present invention provides a logical node deployment method. Considering that the resource capacity of each physical node in the actual system is limited, combined with the total amount and distribution of currently available physical resources in the actual system, the requirements of the integrated business system are given A method for deploying a logical node. The logical node is still described using the virtual node in Embodiment 2 as an example.

[0110] The virtual node deployment method in the third embodiment includes a node deployment algorithm alg_lb(n, m, P, p) that integrates load balancing requirements.

[0111] The starting point of the alg_lb algorithm is to achieve the goal of improving system reliability. Based on the principle of physical resource scheduling that averages the load pressure of physical nodes as much as possible, in step 3 of alg_core, according to the successor relationship (x, y) of the current deployment node and ...

Abstract

The embodiment of the present invention discloses a method and equipment for deploying a logical node with a successor backup relationship. The method includes: step 1, obtaining the logical node to be allocated and the physical node carrying the logical node; step 2, for any bearer The physical nodes of the plurality of logical nodes are configured to carry the subsequent backup relationship of the plurality of logical nodes to point to other different physical nodes respectively. The invention solves backup failure and avalanche effect caused by physical node failure.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for deploying logical nodes with a successor backup relationship. Background technique [0002] Since Amazon launched the "elastic computing cloud" platform EC2 (Elastic Compute Cloud) in 2006 and achieved great success, the industry has widely begun to provide data center infrastructure internal integration (private cloud) or external leasing services based on virtualized elastic resource pools Research on this new business model (public cloud of IaaS model). [0003] As the core component of cloud computing resource pool, although it provides many features such as dynamic deployment and virtual machine management, automatic load balancing, server integration, and dynamic resource scaling and division for upper-layer (third-party) business systems using IaaS services, it is aimed at large-scale data The existing virtualized infrastructure management system in th...
