The link that has a higher transfer rate like gigabit is preferred over the link that has the lower capacity like 56 kb. The bandwidth is measured in terms of bits per second. Bandwidth: The capacity of the link is known as a bandwidth of the link.The path having the lowest delay value will be considered as the best path. The protocols use this metric to determine the delay values for all the links along the path end-to-end. Delay: It is a time taken by the router to process, queue and transmit a datagram to an interface.If the routing protocol considers the hop as a primary metric value, then the path with the least hop count will be considered as the best path to move from source to the destination. Hop count: Hop count is defined as a metric that specifies the number of passes through internetworking devices such as a router, a packet must travel in a route to move from source to the destination.The most common metric values are given below: For some protocols use the static metrics means that their value cannot be changed and for some other routing protocols use the dynamic metrics means that their value can be assigned by the system administrator. Metrics are the network variables used to determine the best route to the destination. The factors used by the protocols to determine the shortest path, these factors are known as a metric. Routing metrics and costs are used for determining the best route to the destination. The routing algorithm initializes and maintains the routing table for the process of path determination.used by the routing algorithm to determine the optimal path to the destination. The metric is the standard of measurement such as hop count, bandwidth, delay, current load on the path, etc. The routing protocols use the metric to determine the best path for the packet delivery.The routing algorithm is nothing but a software responsible for deciding the optimal path through which packet can be transmitted. The routing algorithms are used for routing the packets.

A router is a networking device that forwards the packet based on the information available in the packet header and forwarding table.

A Router works at the network layer in the OSI model and internet layer in TCP/IP model.

Routing is performed by a special device known as a router.

A Router is a process of selecting path along which the data can be transferred from source to the destination.
