7 DISCUSSION AND
CONCLUSIONS
Our proposed extensions to the SOCKS protocol
could lead to a new version of the protocol, which
when implemented, would greatly enhance the
capabilities of the protocol in securing and auditing
application layer traffic. With the convergence of
voice, video and data and the global adoption of IP as
a low cost medium for conducting multimedia
communications, it is highly valuable to add
multicast capabilities to a proven protocol like
SOCKS. While the new features we are
implementing will add value to the protocol, the
performance of the system will only be limited by the
network with no additional performance overhead
added by the new extensions. The application of
security policies and the initial setup of the channel
through socks might cause some delay in the setup
phase when an acpplication is reaching out to the
socks server to cross the network boundary but once
authenticated and authorized, there will be no further
delays added by socks. We expect the proposed
multicast relay process in socks to improve the
performance of multicast routing within the network
compared to other schemes where multicast packets
would need to be routed in a unicast fashion to
listeners in the protected network. We expect the
benefits of adding UDP tunneling and multiple TCP
and UDP bind support in the protocol to be well
received in a variety of application domains,
especially in the N-tier application server domains
and IP telephony.
