Virtual network mapping method based on business merging

Abstract

The invention discloses a virtual network mapping method based on business merging. The method mainly comprises the following steps of merging two business requests bm and bn which are reached adjacently according to operation time; establishing a logic network VN1 according to the business bm, establishing a logic network VN2 according to the business bn, and then merging the VN1 and the VN2 through a virtual chain with a bandwidth of zero, namely overlapping the businesses bm and bn; allocating a bottom-layer physical network to establish a logic network to meet the demands of a merged business requirement; if the merging cannot be succeeded due to insufficient resource of the bottom-layer physical network, establishing a logic network for the business bm independently, and trying to merge the business bn with a next adjacent business b3. According to the method provided by the invention, as two or more adjacently reached businesses are merged, the business request acceptation rate and the balance of the bottom-layer network resource are improved, and the mapping successful rate of the virtual network is improved.

Description

technical field [0001] The invention relates to the field of network virtualization, in particular to a virtual network mapping method based on business combination. Background technique [0002] With the continuous emergence and change of new features and requirements of the Internet, it is required to transform the existing network architecture so that it can be flexible enough to respond quickly to new services and requirements, but the transformation can only rely on the The existing network architecture needs to be upgraded and expanded, and the cost of doing such operations on the huge network system of the Internet is very high; in addition, our network resources are shared, and the services deployed on it are likely to interfere with each other. In order to break this deadlock in Internet technology, network virtualization is one of the effective solutions. Network virtualization is a software-based approach to separating required network traffic from physical n...
