摘要:
IP组播是一种有效的数据传输方式,在过去几年中,组播传输机制已经成为一个活跃的研究领域。但由于其自身特性决定了在组播中实现可靠性和拥塞控制非常困难,组播的拥塞控制问题一直没能得到很好的解决,这成为了其发展的瓶颈,不断增加的UDP数据流恶化了TCP控制拥塞的能力,而且是引起高丢包率的原因之一。文中提出了一种可以对局域网内IP分配固定带宽的扩展令牌桶算法,扩展了令牌桶个数,一个令牌桶控制一个IP,消除了共享带宽的缺点,并通过设计电路,建模仿真结果表明可以对路由器交换节点的组播达到准入控制,防止造成网络拥塞,最大限度保证网络Qos,并且设计的电路占用硬件资源少,能够应用于高速电路当中
Abstract:
IP multicast is an effective data transmission,over the past few years,the multicast transmission mechanism has become an active area of research.However,it is very difficult to realise reliability and to achieve in multicast congestion because of its characteristics,multicast congestion control issues have not been able to get a good solution,it has become a bottleneck in its development.The increasing deterioration of the UDP data stream aggravates the ability of TCP congestion control,and it is one of the reasons to cause high packet loss rate.It presents a way to assign a fixed IP on the LAN bandwidth expansion token bucket algorithm,extends the number of token bucket,a token bucket control of an IP,eliminating the shortcomings of shared bandwidth,and through the design of circuits,modeling and simulation results show it can control the access of multicast and ensure the Qos of network and the design of the circuit occupies less hardware resources,which can be used in high speed circuits
