Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the disadvantage that the existing shared network bandwidth resources cannot be shared fairly, and propose a method and system for realizing the fair allocation of multi-user bandwidth in optical networking. The new business of the user provides redundant resources; in the case of congestion, the bandwidth resources are allocated to the new business reasonably, thus improving the bandwidth utilization of the optical network

Embodiment Construction

[0028] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] figure 1 Is the flow chart of the embodiment of the method of the present invention.

[0030] 101. When a new service requirement appears, according to the bandwidth information identified at the UNI interface, the occupancy of link bandwidth resources is counted.

[0031] 102. Determine whether the link will be congested in order to meet the new service requirement. The so-called congestion means that the bandwidth required by new services is greater than the idle bandwidth currently existing in the optical network.

[0032] If it is judged that there is no congestion, then enter step 105, and allocate bandwidth resources to the new business to meet the needs of the business;

[0033] If it is judged that there is congestion, then enter step 103;

[0034] 103. Calculate the bandwidth occupancy of users including the new service ...

Abstract

In order to overcome the shortcoming that existing shared network bandwidth resources cannot be shared fairly, the present invention proposes a method and system for realizing fair distribution of multi-user bandwidth in optical networking. The method of the present invention comprises the following steps: when a new business requirement occurs, count the occupancy of the link bandwidth resource (ODUk), judge whether the link is congested, and if so, perform bandwidth processing on users whose occupancy exceeds the weight ratio to generate idle bandwidth resources until the idle bandwidth resources meet the new business needs. The system of the present invention includes a control layer device and an optical network device connected with the control layer device. The method and system of the present invention realize rapid deployment of services under the condition of optical network bearing packet network, satisfy fairness under multi-user multiplexing conditions, realize control of bandwidth resource allocation of optical network equipment, and improve bandwidth utilization rate of optical network resources.

Description

technical field [0001] The embodiments of the present invention relate to the field of network technologies, and in particular to a method and system for fairly allocating bandwidth of an optical network bearer packet network. Background technique [0002] In the environment where the optical network carries the packet network, the service requirements in the packet network change dynamically, and the bandwidth occupied by each service link changes statistically. [0003] In an optical network, bandwidth resources allocated to users are fixed for a long period of time. If the weight is used to measure the qualification of the user to enjoy the bandwidth service, how much bandwidth resource is allocated to the user can be determined by the weight of the customer. For example, users who pay more should get more bandwidth than users who pay less, and users who pay the same amount should have the same service blocking rate. Therefore, users with higher weights will be allocated...
