为了解决服务链部署中的路径循环和源地址绑定问题,首先,提出一种新的服务链部署方法,该方法利用OpenFlow多级流表标识服务链及服务顺序,从而使数据分组按照需求的服务顺序正确处理;其次,提出服务链部署算法以实现服务路径到流表规则的映射;最后基于NetFPGA-10G完成了原型系统实现。仿真结果表明,该部署方法具备可行性,并降低了流表数量和时间开销。
Aiming at the path cycle and source address binding problem in middlebox service chain deployment,a service chain deployment approach by combining the OpenFlow mechanism and NetFPGA was proposed.First of all,the OpenFlow multi-flow table was used for marking service chains and labeling service sequences so that data packets could be processed correctly according to desired service order;secondly,the service chain deployment algorithm was designed to achieve the mapping relationship between the service path and flow table rules;thirdly,a prototype system was implemented based on the hardware platforms of NetFPGA-10G.Finally,experimental results show that the proposed method have the advantage of feasibility and outperforms compared methods in the aspect of the flow table number and time overhead.
