# SSDP - Simple Service Discovery Protocol - easy discovery of network devices # Pattern attributes: good slow notsofast # Protocol groups: networking ietf_draft_standard # Wiki: http://www.protocolinfo.org/wiki/SSDP # This pattern was tested only by listening to a Linksys WRT54G. However, # I expect it works in general given the simplicity of the protocol. # SSDP packets should _always_ be sent to the multicast address # 239.255.255.250, making this pattern irrelevant. (Moreover, SSDP # packets should be resitricted to local networks that have plenty of # bandwidth.) However, Microsoft, as usual, has other ideas, so maybe # it could be useful. Can't hurt, anyway. :-) # # http://www.upnp.org/download/draft_cai_ssdp_v1_03.txt # http://msdn.microsoft.com/library/default.asp?url=/library/en-us/randz/protocol/ssdp.asp ssdp ^notify[\x09-\x0d ]\*[\x09-\x0d ]http/1\.1[\x09-\x0d -~]*ssdp:(alive|byebye)|^m-search[\x09-\x0d ]\*[\x09-\x0d ]http/1\.1[\x09-\x0d -~]*ssdp:discover
