Proxies
Proxies are systems that behave like servers, yet pass the work on to
other network systems using the same protocol. They appear to be a
server to their client, and as a client to their upstream server.
Proxies are useful for several reasons:
- They can distribute administration of systems to a configurable
grouping, including the maintenance of security associations,
- They can be used for concentration of requests from an number of co-
located or distributed NAS equipment sets to a set of like user
groups
- They can do value-added processing to the requests or responses
- They can used for load balancing,
- A complex network will have multiple authentication sources, they can
sort requests and forward towards the correct target
