This problem is about query flooding in p2p networks. here, we explore the reverse-path routing of the queryhit messages in gnutella. suppose that alice issues a query message. furthermore, suppose that bob receives the query message (which may have been forwarded by several intermediate peers) and has a file that matches the query. 5.1. as we know when a peer has a matching file, it sends a queryhit message along the reverse path of the corresponding query message. an alternative design would be for bob to establish a direct tcp connection with alice and send the queryhit message over this connection. what are the advantages and disadvantages of such an alternative design?
