Abstract

The invention provides a method for equitably distributing multi-user bandwidth in an optical network to overcome the defect that existing shared network bandwidth resources cannot be shared equitably. The method comprises the following steps that when a new service requirement occurs in the network, whether service blockage exists or not is judged, and when service blockage is found, the equitable degree of a user dealing with the new service is calculated; the equity of resource distribution is judged; whether the user dealing with the new service is a super-equitable user or not is judged, if yes, the service is refused, and if not, the user with the largest equitable degree value is a target user, the bandwidth occupied by the target user is adjusted, the equitable degree of the target user approaches the ideal level, and idle spectrum resources are produced; whether the idle spectrum resources meet the new added service requirement or not is judged, if yes, the process is ended, and if not, the target user is changed. According to the method, due to the fact that the technical measure of network bandwidth equity calculation is taken, the effect that multiple users share the network resources equitably is achieved.

Description

technical field

[0001] The invention relates to the field of network technology, in particular to a method for fairness among multiple users of a data center in an optical network. Background technique

[0002] With the development of cloud computing and multiple cloud services, data centers are faced with the situation that multiple users share computing resources (CPU and RAM), storage resources and network resources. With the help of virtualization products, the multi-user environment of the data center provides the choice of CPU frequency and memory size, but cannot provide bandwidth guarantee and fairness strategy. In the data network, fairness can be defined in many ways. For example, users who pay more should get more bandwidth than users who pay less, users who pay the same should have the same service blocking rate, and so on. In the network, users' eligibility for services is measured by their "weight".

[0003] In IP networks, there are many studies on fair shar...
