Abstract
Network and host efficiencies are improved by reducing the overhead associated with establishing virtual circuits. In one approach, a request for information from a client is sent to a server using a connectionless protocol such as UDP. If the requested information satisfies a policy for return by the connectionless protocol, the response is sent that way. If the policy is not satisfied, the server may reply with a message to try a connection oriented protocol such as TCP. If no response is received at all after a certain number of tries, the client will try a connection using a connection oriented protocol. In a second approach, when a request from a client is sent using a connectionless protocol, the state information for a transaction TCP (T/TCP) connection is set up in the client, giving the server the option of responding either using the connectionless protocol or using T/TCP. Transparent proxies can be conveniently implemented which will handle asymmetric connections and efficiently return cached information.
