Network Protocols Layer Wise

A network protocol is an established set of rules that determine how data is formatted transmitted and received between devices across networks. While OSPF and EIGRP are popular for internal routing enterprise-to-enterprise and enterprise-to-Internet routing always fall to one popular protocol BGP which is universally used across the Internet.

Unless theres a very specific reason to stray from OSPF or EIGRP such as routing non-IP traffic it is wise to avoid alternative Layer 3 protocols for internal network routing.

Network protocols layer wise. The networks are organized and arranged as different layers or levels simply to reduce and minimize complexity of design of network software. While TCP is designed to provideconnection-oriented delivery of packets UDP implements a connectionless orunguaranteed delivery mechanism that is suitable for a number of upper layerapplications. The common protocols at this layer are IP which is paired with TCP at the transport layer for Internet network and IPX which is paired with SPX at the transport layer for some older Macintosh Linus UNIX Novell and Windows networks.

Below is diagram representing a five-layer network. Protocols at the network layer are also responsible for route selection which refers to determining the best path for the data to take throughout the network. To effectively send and receive information devices on the two sides of a communication exchange must follow protocols.

For some applications the overhead of TCP such as handshakingis not required. The data stream is passed through a number of layers from one host to other. Network Protocols are a set of guidelines governing the exchange of information in a simple dependable and secure way.

The network layer is in charge of routing network messages data from one computer to another. File Transfer Protocol FTP 20 and 21 TCP It is a protocol that carries. 32 rows 1.

The User Datagram Protocol or UDP is the other most commonly used Trans-port layer protocol found within the Internet. A network protocol is essentially a language that two devices can both understand in order to communicate with each other regardless of internal process infrastructure or design disparities. Network protocols are formal standards and policies comprised of rules methodology and configurations that define communication between two or more devices over a network.

In contrast to the data link layer which uses MAC addresses to communicate on the LAN network layer protocols. The diagram shows communication between Host 1 and Host 2.
