Optimized Strategy of Broadcast and Multicast in Virtual Network Based on Pipeline Thinking
Ming Liu · Jisuanji gongcheng · 2011
Broadcast and multicast application based on TCP/IP protocol in link layer and realization of virtual network device,for multi-processors environment,based on shared memory under VxWorks are introduced.A contrast of physical and link layers is made between the Ethernet and the virtual networks device upon broadcast and multicast.The virtual network device's drive for VxWorks with its operation on the broadcast and multicast is analyzed.And an optimized scheme on broadcast and multicast on multi-Longson 2E processors parallel signal processing mainboard pointed to virtual network device's physical character is designed and realized which is based on pipeline thinking.The real time performance,balance of the net node load and the transmission efficiency are improved greatly.
