Embodiment

[0054] figure 1 It is a flowchart of a specific embodiment of the cross-data center virtual network mapping method of the present invention;

[0055] In this example, if figure 1 As shown, the virtual network mapping method across data centers of the present invention, the specific steps of its implementation include:

[0056] S101. Determine the survivability requirements s of the virtual network V : virtual node n V mapped on physical node n S The above is expressed as: n V →n S :M(n V ) = n S ,n V ∈V V ,n S ∈V S ;

[0057] When M(n V ) = n S when x(n V ,n S ) is 1, otherwise x(n V ,n S ) is 0, then the viability constraint is:

[0058] Σ n V ∈ V V x ( n V , n S ) ...

Abstract

The invention discloses a virtual network mapping method for a cross-data center. Under the condition that survival capability demands and reliability of a virtual network are ensured, first of all, partition is performed on virtual nodes in the virtual network through virtual node group partition (VNGP), based on current packets, all node pair sets among the different packets are searched for, final partition is determined, and then the virtual network after the partition is mapped to a bottom-layer data center network through a GVNM sub-algorithm. According to the invention, under the condition that the survival capability demands are ensured, the virtual nodes are mapped to the same data center, such that communication resources are saved. Besides, a reliability enhancement method in the data center is also employed, such that the reliability of the virtual network is ensured, and at the same time, the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of Internet communication, and more specifically relates to a cross-data center virtual network mapping method. Background technique [0002] At present, the Internet has achieved great success in the model of the way information is acquired and exchanged. Over the past three decades, the Internet has proved the value of its own structure by supporting a large number of decentralized applications and a large number of different network technologies. However, the Internet The widespread use of the Internet has also become the biggest obstacle to its further development. Due to its multi-vendor nature, adding new structures or adjustments to the existing structure of the Internet requires the common approval of all operators, so the current network structure is limited. Only slow and simple updates can be carried out, but rapid changes cannot be carried out. [0003] Network virtualization, as a technical mea...
