What is Dynamic Network Routing?

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 shares information among routers

· With the change in topology, routing tables are automatically updated

· Finds out best path to the destination

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