VppCOM 是一个分布式数据通信中间件，吸收了高层体系结构 HLA 的公布订购思想，具有可重用性、可扩展性好的特点；VppCOM 通信中间件仅包含 6 个服务，使用简捷、方便，可广泛应用于陆海空天等不同软件系统间的互联和数据通信。在很多情况下，它可取代RTI 等软件来高效快捷地开发一个分布应用系统。

共享以太网：在共享网络环境中，所有的主机都连接到同一条总线并且与其他的主机竞争带宽。这意味着在这样的环境中，发给某个主机的数据包也会被其它所有的机器收到。因此在这样的环境中，任何设置成混杂模式的主机，将可以捕获发送给其它主机的数据包，从而窃听网络上的所有通信。 -Ethernet sharing : sharing network environment, all of the hosts connected to a bus with other mainframe competition bandwidth. This means that in such an environment, to a host of data packets will be all other machines received. In such an environment, any set pattern of mixed mainframe, will be sent to the capture of other mainframe data packets, thereby tapping on the network for all communications.

A basic exemple on how-to use "Winsock2" with Visual-C++ 6 to sniff the network without Winpcap. Also you can see how is the implementation of "WSAIoctl()" with the SDK2003. In this code, we analyse the TCP trame and show information about the ip header and contained data.-A basic exemple on how-to use "Winsock2" with Visual-C++ 6 to sniff the network without Winpcap.
