router vs packet forwarding [7:50471]

2002-08-01 Thread John Green

what is the difference between router and a device
that does packet forwarding between its interfaces.

example:
can a plain NT box with two network cards (with IP
forwarding enabled) be called as a router ? or it is
just doing packet forwarding. 
in my understanding even routers like say cisco router
does such packet forwarding though it can make a
decision on such packet forwarding based on a routing
protocol. would that be correct to say ?

In a sense the NT box is acting as a router...  I think by default it
would only know the two networks that are attached (like a router would) but
you can add your own routes to an NT/2000/XP box, effectively you could use
it as a router that only understands static routes (although I think you
could use RIP with them I'm not sure if I'm confusing NT/2000 with another
OS)...

Partially marketing, partially an ability to scale (general purpose os'
generally tend to get burdened with tasks that deprive the routing threads
of vital system resources).

As a device that passes data between two L3 networks, and makes decisions
based upon L3 header information, you can call it a router.

As a device that is dedicated to, and designed for, routing, you probably
wouldn't want to.

They both forward packets.

Well to tell you the truth a NT box with IP forwarding enabled and dual NIC
cards is truely a router with L3 functinality. But Cisco or Juniper or
Nortel add a lot of extra features in to the boxes to enhance the routing
performance features like latency, QoS and stuff like that.
These boxes are made to do only L3 functionailty not a NT box with 2 E or FE
ports. A router can have virtually any kind of interface that can be thought
off. A router has a much faster RAM called the Flash (expensive too).
Now I would anyday use a NT box for computing only anad a specialist router
to do L3 routing between networks. I am sure the amount of traffic that can
pass through the L3 devices in todays networks (20/80 rule) will toast the
NT box.
