The layered network
The layered network will be essential to network engineer since it’s categorized as the third level of the Open system Interconnection model. Also, the layer is of importance in providing the data routing paths for network communication. An open system interconnection model in the network layout gives the description and the functionality in the communication system using the abstract layers. However, the networking link layer is equal to the hardware devices and the interface card. Depending on the type of link layer, the data packets have variations in performance and style.
The network engineer will benefit from managing the transformation of packets around the network, which involves the IP, ICMP, and IGMP. These are responsible for ensuring the packages in the system reach the destination and then report the errors if they cannot make it. In the transport layer, the mechanism to be used among the computers in exchanging the data regarding the software to be used has protocols that include the TCP and UDP.
The network engineer will enjoy using FTP, Telnet, and BOOTP to support the various services. The engineer can define its data structure using the network layered in communicating with the client so long they use the serving machine which comprehends the protocol.
