Embodiment Construction

[0011] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] The invention discloses a method for dynamic bandwidth allocation based on SDN multi-service, which specifically includes the following steps: the first type of SDN service (in SDN, when applying for a service flow, parameters such as service priority will be carried, and the parameter is used to judge that it is the first Several types of SDN business)) have the highest priority, first assign fixed bandwidth to it (generally 60% of the total bandwidth in the current network); then non-SDN business (design the data from the SDN northbound interface as SDN business; The data coming from the SDN southbound interface, that is, the data coming through the link discovery protocol packet in is called non-SDN business) to reserve a part of the minimum bandwidth (generally 5-6% of the total bandwidth); and then according to the ca...

Abstract

The invention relates to the technical field of bandwidth allocation. The invention discloses an SDN-based multi-service dynamic bandwidth allocation method, which includes the following steps: Step 1. The first type of SDN service has the highest priority, and a fixed bandwidth is allocated to it first. Step 2. In the case of reserving a part of the minimum bandwidth for non-SDN services, dynamically allocate bandwidth for the second priority SDN services according to the calculated current maximum bandwidth quantity and the weight of each service. Step 3: After allocating bandwidth for the first two services, allocate the remaining bandwidth to non-SDN services in proportion to demand. The method of the invention can effectively improve business service quality and system bandwidth utilization rate, ensure the bandwidth guarantee of high-priority SDN business, and each SDN business with different priority can obtain different degrees of bandwidth resources. At the same time, it ensures that non-SDN services will not be denied service in SDN, and meets the common needs of all services.

Description

technical field [0001] The present invention relates to the technical field of network resource allocation, in particular to a method and system for dynamic bandwidth allocation based on SDN multi-service. Background technique [0002] Software-defined networking (SDN) is a new type of network architecture, which realizes the possibility of flexible control of the network through software by separating the forwarding and control planes of the network. In the current diversification of SDN services and non-SDN services, there is a lack of corresponding processing methods for how to allocate bandwidth resources according to the different requirements of SDN services and non-SDN services. [0003] CN201310363478.6 discloses a public network resource allocation method and system, the method includes: receiving a user service demand access request message, and obtaining the user service demand type; according to a preset service type priority parameter, obtaining the user The pr...
