Novell Routing Concept
Novell IPX Routing
Network number
assignment
A globally unique network number must be assigned to each network connection
of a NetWare* server. Servers and router links attached to the same physical net-
work must be configured with the same network number. To simplify network
management, only servers and routers must be configured with a network num-
ber, as workstations automatically get their network number assigned by the
server (connection to local server) or router (connection to remote server).
Sockets reserved by
Novell
Each service reserved is allocated to a specific socket number. The following
sockets are reserved by Novell:
Novell Metrics
Delays and hops The Novell metrics are used to calculate the optimal route between networks (for
IPX RIP) and services (for IPX SAP). Novell metrics use the following to calcu-
late the best routes:
Delays (Ticks)
The delay is the time associated with sending data via a route, that is, if alterna-
tive routes are available the data packet is transmitted via the route that takes the
least time.
The delay is measured in time ticks where 1 second = 18.21 time ticks.
Hops
The hops is the number of intermediate networks that must be passed in order to
reach the destination network. Hops are only used in the unlikely event that two
routes have an identical time tick; the route with the least number of hops is then
be used.
