Dynamic
Network Routing (DNR) is a network service that routes incoming phone calls to
different phone numbers and locations, based on the day of week. It allows
routers to choose paths according to real-time logical network layout
variations. Based on a company’s business hours, customers’ phone calls are
routed and forwarded to another facility. Routing allows calls to be sent to
different extensions based on the day of the week.
Dynamic
network routing is also known as adaptive routing. This networking technique
provides optimal data routing. Unlike static routing, dynamic routing enables
routers to select paths according to real-time logical network and layout
changes. Routing protocols are used to facilitate the exchange of routing
information between routers. Routing protocols allow routers to dynamically
learn information about remote networks and automatically add this information
to their own routing table.
In dynamic
routing, the routing protocol operating on the router is responsible for the
creation, maintenance and updating of the dynamic routing table, whereas in
static routing, all these jobs are manually done by the system administrator.
Dynamic routing is done without any help of human intervention, it
automatically make changes and provides the best path for data transmission. As
routers share updates, it consumes more bandwidth than static one.
DNR consists
of several routers and automatically determines better routes, if there is any
change in the topology. It is independent of network size. With possible change
in the routes, dynamic routing protocol allows changes. Dynamic Routing
protocols are grouped according to characteristics including RIP, IGRP, EIGRP,
OSPF, IS-IS, and BGP. DNR is easy to configure on large networks and it is
readily accepted by almost all call center
services.
Functions of
Dynamic Network Routing
·
Dynamically

Dynamic routing
protocol has two types of routing protocols; one, Interior Gateway Protocol
(IGP); and second, Exterior Gateway Protocol (EGP).
