In link-state routing protocols, the primary path attribute used to choose the best path to a destination network is the cost or metric associated with each path. This cost is typically based on factors like bandwidth, delay, or other criteria defined by the network administrator. The protocol calculates the shortest path using algorithms like Dijkstra's algorithm, selecting the route with the lowest total cost.
Which routing protocol depends on the DUAL algorithm to calculate the shortest path to a destination
Layer N in the model accepts data from the next higher layer, layer N+1, in the form of a block of data known as a service data unit (SDU). To deliver this SDU to the destination system, a layer N protocol is used between the layer N entity in the source system and the layer N entity in the destination system. The source protocol entity encapsulates the SDU by adding a header and possibly a trailer, containing protocol control information, such as source and destination address and error check codes. The SDU plus header and trailer is known as a protocol data unit (PDU). An SDU may be broken up into multiple chunks and sent out in multiple PDUs, or multiple SDUs may be aggregated and send out in a single PDU, if the protocol allows it.
data reassembled at the destination =))
DHCP
protocol is a connection establishment between the source computer to destination computer ex: tcp / ip protocol
Internet destination refers to the location that a process is aimed to get to. This part of the internet control message protocol with the destination expected to decode the message.
IP (Internet Protocol)
The protocol responsible for directing data to its destination is the Internet Protocol (IP). IP handles addressing and routing, ensuring that packets of data are sent from the source to the appropriate destination across networks. It operates at the network layer of the OSI model and works in conjunction with other protocols, such as TCP or UDP, to facilitate reliable communication.
The details vary enormously from protocol to protocol, but the basics are the same for all of them. A stream of data is split into packets, the packet has a header which contains (amongst other things) the destination for the packet. The network uses the destination address to deliver the network to the correct destination.
Point-to-Point Protocol.
the primary weakness in the ICMP protocol is that, it does provide authentication to verify the destination address.
Yes protocol is need for every transmission so that any trasmitted data can surely reach to there destination.........
