NETWORK A friend was having trouble when his roomates were using every one's favriote peer to peer program, and he asked me look at what was going on. After recieving a pcap file showing the internals of the network, it showed that there was an insane amount of multicasts from a protocol called ssdp. I hadn't heard of ssdp and I did a little reasearch. I determined that either Upnp or p2p had to go. I wasn't satisfied with my determination because I didn't feel confident enough to validate myself. After a few quick searches I found a blog that seemed accurate and made me feel confident enough to propose my theory Lee. He reccomended checking out Steve Gibson's site grc.com.
