Packet forwarding is the relaying of packets from one network segment to another by nodes in a computer network. The network layer in the OSI model is responsible for packet forwarding. However, other forwarding strategies are commonly used. Broadcasting requires a packet to be duplicated and copies sent on multiple links with the goal of delivering a copy to every device on the network. In practice, broadcast packets are not forwarded everywhere on a network, but only to devices within a broadcast domain , making broadcast a relative term. Less common than broadcasting, but perhaps of greater utility and theoretical significance, is multicasting , where a packet is selectively duplicated and copies delivered to each of a set of recipients.

Login Now. The mobile i. CN may not know the exact location of MN. The internet, which does not have any information of the current location of MN, routes the packet to the router responsible for the home network of MN. This is done using the standard routing mechanisms of the internet. The packet is not forwarded into the subnet as usual, but encapsulated and tunnelled to the COA. Again, for the MN mobility is not visible.

Packet goes from routers to routers. □ For indirect delivery. ▫ The sender uses the destination IP address and a routing table to find the next router's IP address.

It is valid for all types of engineers including entry-level network engineers, network administrators, network support engineers and network specialists. It helps to become familiar with broad range of networking concepts like OSI models, IP addressing, Network security, etc. It is estimated that more than 1 million CCNA certificates have been awarded since it was first launched in It helps candidates to study CCNA fundamentals and prepare for the latest network technologies they are likely to work on.

In the seven-layer OSI model of computer networking , the network layer is layer 3. The network layer is responsible for packet forwarding including routing through intermediate routers. The network layer provides the means of transferring variable-length network packets from a source to a destination host via one or more networks.
