摘要
基于以太网的组播速率较低,无法满足实时系统,且无拥塞控制机制,易出现丢包、乱序等现象;同时,基于以太网组播的应用程序不能直接移植到反射内存网。针对上述问题,提出了一种基于反射内存网的组播实现方案,将组播技术与反射内存网技术相结合,实现了参与组播的各节点间的高速通信。该方案的实现,不仅提高了节点间的通信的可靠性,还提高了基于以太网组播的应用程序的可移植性。
The rate of the Ethernet-based multicast is too slow to apply to real-ime systems. And it also has no congestion control mechanism, which leads to packet-loss and out-of-order. Besides, the application of Ethernet-based multicast can＇t be ported to reflective memory network directly. Aiming at solving the problems above, a reflective memory network-based multicast implementation was developed, which combined muhicast with reflective memory network to accomplish high-speed communications among nodes involved in muhieast, With the implementation of reflective memory network-based multieast, both the reliability of communication among nodes and the portability of applications based on Ethernet muhicast are improved greatly.
