guidance for proxies to limit the number of concurrently registered CIDs #109

Open ehaydenr opened 1 month ago

A client can send many bogus REGISTER_TARGET_CID/REGISTER_CLIENT_CID capsules. A proxy has to maintain the forwarding / port demultiplexing rules for each of the registered CIDs it acknowledges. Should proxies signal some limit? Or should they merely CLOSE_CLENT_CID/CLOSE_TARGET_CID when the limit is exceeded?
