Network management protocols help define the policies and procedures used to monitor, manage and maintain your computer network, and help communicate these needs across the network to ensure stable communication and optimal performance across the board. Show
Generally, network managers can use a management protocol to troubleshoot connections between host and client devices. Management protocols provide network managers with the host connection's status, availability, packet or data loss, and other related information about the health of the network connection. The policies managed by management protocols can be applied to all devices on the network, including computers, switches, routers and even servers. Two of the most common types of network management protocols include Simple Network Management Protocol (SNMP) and Internet Control Message Protocol (ICMP).
Here, hierarchical means that each upper-layer protocol is supported by two or more lower-level protocols. Functions of TCP/IP layers:Network Access Layer
Internet Layer
Following are the protocols used in this layer are:IP Protocol: IP protocol is used in this layer, and it is the most significant part of the entire TCP/IP suite. Following are the responsibilities of this protocol:
ARP Protocol
ICMP Protocol
Transport LayerThe transport layer is responsible for the reliability, flow control, and correction of data which is being sent over the network. The two protocols used in the transport layer are User Datagram protocol and Transmission control protocol.
Application Layer
Following are the main protocols used in the application layer: HTTP: HTTP stands for Hypertext transfer protocol. This protocol allows us to access the data over the world wide web. It transfers the data in the form of plain text, audio, video. It is known as a Hypertext transfer protocol as it has the efficiency to use in a hypertext environment where there are rapid jumps from one document to another.SNMP: SNMP stands for Simple Network Management Protocol. It is a framework used for managing the devices on the internet by using the TCP/IP protocol suite.SMTP: SMTP stands for Simple mail transfer protocol. The TCP/IP protocol that supports the e-mail is known as a Simple mail transfer protocol. This protocol is used to send the data to another e-mail address.DNS: DNS stands for Domain Name System. An IP address is used to identify the connection of a host to the internet uniquely. But, people prefer to use the names instead of addresses. Therefore, the system that maps the name to the address is known as Domain Name System.TELNET: It is an abbreviation for Terminal Network. It establishes the connection between the local computer and remote computer in such a way that the local terminal appears to be a terminal at the remote system.FTP: FTP stands for File Transfer Protocol. FTP is a standard internet protocol used for transmitting the files from one computer to another computer.What is TCP IP protocol in computer network?TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet. TCP/IP is also used as a communications protocol in a private computer network (an intranet or extranet).
Which TCP IP based management protocol implemented on routers provides for security?The Internet Protocol Security (IPsec) authentication and encapsulation standard is widely used to establish secure VPN communications. The use of IPsec can secure transmissions between critical servers and clients. This helps prevent network-based attacks from taking place.
Which of the following TCP IP protocols exist at the transport layer of the TCP IP reference model choose two?User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) exist at the transport layer.
Why are PCS installed with TCP IP protocols?TCP/IP provides facilities that make the computer system an Internet host, which can attach to a network and communicate with other Internet hosts.
