Routing information protocol (RIP) is a routing protocol that lets routers of an autonomous system inform each other about the changes inside the network. It is an intra-domain routing protocol as it updates the routing tables of routers inside an autonomous system. Routing specifies all those protocols that define the route of packets from source to destination across multiple … [Read more...] about Routing Information Protocol
Address Mapping
Address mapping is a process of determining a logical address knowing the physical address of the device and determining the physical address by knowing the logical address of the device. Address mapping is required when a packet is routed from source host to destination host in the same or different network. Why Address Mapping? We know that the Internet is a collection of … [Read more...] about Address Mapping
IP Over ATM
IP over ATM is the transmission of IP datagram over a switched network such as ATM (Asynchronous Transfer Mode). In our few earlier contents, we have seen transmission of IP datagram over the connectionless LAN and point-to-point WAN that uses the available line to communicate. In this section, we will discuss the transmission of IP datagram over the switched ATM WAN network … [Read more...] about IP Over ATM
Fragmentation in Networking
Fragmentation is a technique implemented on a datagram at the network layer if the size of the datagram is larger than the size of the datagram that the corresponding network can forward. This technique involves the division of the large size datagram into smaller fragments. In this section, we will study all about the fragmentation of datagram in the network … [Read more...] about Fragmentation in Networking
Network Layer Functions
The network layer function is to provide end-to-end communication between the two computers where the source and the destination computers may be in the different networks. When the source and destination computers communicate with each other the packet from the source has to travel through several LANs or WANs to reach the destination. As the packet travels across different … [Read more...] about Network Layer Functions
