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, and discloses a multi-service dynamic bandwidth allocation method based on an SDN (Software Defined Network). The method comprises the following steps: I, firstly, allocating fixed bandwidths to first-type SDN services with a highest priority; II, under the situation of reserving a part of minimum bandwidths for non-SDN services, dynamically allocating bandwidths to SDN services of a second-type priority according to a calculated current maximum bandwidth quantity and weights of the services; and III, after allocation of the bandwidths to the first two types of services, allocating the remaining bandwidths to the non-SDN services according to a demanded proportion. Through adoption of the method, the service quality and the system bandwidth utilization ratio can be improved effectively; the bandwidths of high-priority SDN services are ensured; and the SDN services of different priorities can acquire bandwidth resources of different degrees. Meanwhile, rejection of services for the non-SDN services in the SDN is avoided, and common demands of the services are met.

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...
