Advantages of Routers | disadvantages of Routers
This page covers advantages and disadvantages of Routers. It mentions Routers advantages or benefits and Routers disadvantages or drawbacks. It also describes Routers basics.
What is Router?
This networking device provides interconnection between two dissimilar networks. It operates at layer-3 of OSI stack and takes care of routing of packets based on routing table. It uses IP addressing for routing the packets.
The figure-1 depicts router used to connect ATM and LAN networks. Various algorithms such as RIP, OSPF, BGP are used as router protocols for various functionalities in addition to routing. Refer What is Router >>.
Benefits or advantages of Routers
Following are the benefits or advantages of Routers:
➨It provides connection between different network architectures such as ethernet & token ring etc.
➨It can choose best path across the internetwork using dynamic routing algorithms.
➨It can reduce network traffic by creating collision domains and also by creating broadcast domains.
➨It provides sophisticated routing, flow control and traffic isolation.
➨They are configurable which allows network manager to make policy based on routing decisions.
Drawbacks or disadvantages of Routers
Following are the disadvantages of Routers:
➨They operate based on routable network protocols.
➨They are expensive compare to other network devices.
➨Dynamic router communications can cause additional network overhead. This results into less bandwidth for user data.
➨They are slower as they need to analyze data from layer-1 through layer-3.
➨They require considerable amount of initial configurations.
➨They are protocol dependent devices which must understand the protocol they are forwarding.
