【摘要】：随着互联网的深入发展,越来越多不同类型的业务需要在同一个网络上承载,这使得完全由网络进行的资源分配的方式变得越来越难以满足要求。导致这一结果的原因有两个不可忽视的因素。首先,用户体验的指标(Qo E)折算成网络层可控制的QoS指标是难以精确的。而传统的QoS保障方案恰恰需要应用预先明确报告带宽、延迟等指标。其次,现代的大多数应用在整个生命期内对网络资源的需求是动态变化的。除非过配置资源,否则要求运行前即确定所需资源量是不现实的。由于这样的原因,一种更好的资源分配方式是让应用参与到资源分配过程中,与网络共同进行资源分配决策。而网络与应用合作进行资源分配与已有的网络控制资源分配方案相比,具有更多的不稳定性和对于冲突的不可控性。本文为了发展更稳定的应用和网络进行合作策略,将提供虚假信息作为主要协调手段,力求让网络和应用在各自追求自身利益最佳的情况下仍然能够达到相互折衷的目的。本文研究的主要内容是传统网络、SDN网络和数据中心间网络的路由问题或收费问题改进。其中在传统网络中借助Fibbing技术,通过虚假的网络拓扑影响网络路由器路由表,实现了负载均衡,并减小了平均业务时延。在SDN网络中,通过将路由的决策权交给应用,然后赋予网络提供虚假网络链路参数信息的权力影响应用决策,并通过限制网络谎报参数的范围进行网络与应用利益间的折衷。之后将SDN网络中的谎报策略借用到数据中心间网络的收费问题中,进行更加具体化的利益划分,并降低了数据中心间网络的成本消耗。
[Abstract]:With the further development of the Internet, more and more different types of services need to be carried on the same network, which makes it more and more difficult to meet the requirements of the resource allocation completely carried out by the network. There are two factors that can not be ignored. First of all, it is difficult to convert the user experience index (QO E) into a network layer controllable QoS index. However, the traditional QoS guarantee scheme just needs to apply explicit reporting bandwidth, delay and other indicators. Secondly, the demand for network resources in most modern applications is dynamic throughout the lifetime. Unless resources are configured, it is not realistic to determine the amount of resources required before running. For this reason, a better way to allocate resources is to let applications participate in the process of resource allocation and make resource allocation decisions with the network. Compared with the existing network control resource allocation scheme, network and application cooperation resource allocation has more instability and uncontrollability to conflict. In order to develop more stable application and network cooperation strategy, this paper takes the provision of false information as the main means of coordination, and makes every effort to make the network and application achieve the goal of compromise while pursuing their own best interests. The main content of this paper is the improvement of routing problem or charging problem between traditional SDN network and data center network. With Fibbing technology in traditional network, the routing table of network router is affected by false network topology, which realizes load balancing and reduces the average service delay. In SDN networks, the decision power of routing is handed over to the application, and the power of providing false network link parameter information is given to the network to influence the application decision, and the tradeoff between the network and the application benefits is made by limiting the range of false network parameters. Then, the false report strategy in SDN network is borrowed to the problem of data center network charge, and the benefits are divided more concretely, and the cost consumption of data center network is reduced.
