Research On Network Resource Allocation Based On Fake Information

With the development of the Internet,more and more different types of business needs to be carried on the same network,which makes the way of resource allocation entirely by the network becomes more and more difficult to meet the requirements.The reason for this result has two factors that can not be ignored.First,the user experience(QoE)is difficult to accurately converted into QoS.And the traditional QoS guarantee program need to be reported bandwidth,delay and other indicators in advance.Second,the majority of modern applications in the entire life cycle of the demand for network resources is dynamic.Unless the resources asked by demands are configured,it is unrealistic to determine the amount of resources required before demands running.For this reason,a better way of allocating resources is to allow the application to participate in the process of resource allocation,so that the network can make resource allocation decisions with applications together.However,the cooperation between the network and applications in the resources allocation is more unstable and more uncontrollable for conflicts.In order to develop a more stable application and network cooperation strategy,this thesis will provide false information as the main means to coordinate profits between the network and applications.And try to achieve mutual compromise while both the network and applications are in pursuit of their own interest.The main contents of this thesis are the improvement of routing problems or charging problems in traditional networks,SDN networks and inter-datacenter networks.In the traditional network,this thesis provides false network topology by Fibbing technology to affect the network routers' routing table.Which lead to load balancing,and the reduce of the average business delay.In the SDN network,the routing power is given to the applications,but the network is allowed to provide false information of network link parameters which would influence the application decision.The trade-off between the network benefit and the application benefit is restricted by the limiting range of the network falsification parameters.In inter-datacenter network,this thesis inherit the false parameter algorithm and reduce the network cost.
