优化EPON对本地P2P业务承载能力的研究
发布时间：2018-10-16 23:03
【摘要】：P2P流量已成为网络中的主要流量,但现有EPON系统不能很好的承载本地P2P业务。文中从MPCP协议的角度对逻辑链路标签及其过滤规则进行扩展,使本地P2P数据包不需经OLT端二层交换即可实现下行转发,从而大大改善了P2P业务的QoS。并以此方案为基础,提出改进EPON的DBA算法,设置专门的P2P时隙,实现P2P业务的全光域转发。两种方案的建模仿真结果表明,两者均能明显改善EPON对本地P2P业务的承载能力。
[Abstract]:P2P traffic has become the main traffic in the network, but the existing EPON system can not carry the local P2P services well. In this paper, the logical link label and its filtering rules are extended from the point of view of MPCP protocol, so that the local P2P packets can be transmitted downlink without the need of OLT two-layer switching, thus greatly improving the QoS. of P2P services. On the basis of this scheme, an improved DBA algorithm of EPON is proposed, and a special P2P time slot is set up to realize the all-optical forwarding of P2P services. The modeling and simulation results of the two schemes show that both schemes can obviously improve the bearing capacity of EPON to local P2P services.
