The Bare Bone Protocols of Network Monitoring

The Bare Bone Protocols of Network Monitoring

What happens when the internet connection is down? Who is actually enabling connection to from computer to internet? Protocols are the elves in our cables linking us to the world via internet.

FREMONT, CA: A network protocol is a group of directions and instructions that enable the devices on a network to interact with one another. These protocols comprise methods for machines to recognize themselves and interpret the functions of other devices on the network. Without these protocols, the network hardware cannot function or handle the data transmissions or communicate with each other. The important protocols are:

SNMP Monitoring:

For a device to connect to a network, the Simple Network Management Protocol (SNMP) compatibility should exist. SNMP uses a call-and-response system to interact with various devices and check status conditions. An SNMP manager can send out requests for specific information to analyze. 

TCP and IP Monitoring:

The internet protocol suite is a combination of two protocols, the TCP and IP, which allows the networks of devices to lay out connections with each other devices to transfer data through the connections.

The Transmission Control Protocol (TCP) is an essential protocol for networks to function correctly, as it controls the data transfers. Internet Protocol (IP) formulates unique addresses for every single device and generates network routes for data transmissions.

HTTP Monitoring:

Hyper Text Transfer Protocol (HTTP) monitoring can mainly cross-verify the availability of websites and deliver information when the mission-critical services are down. The protocol monitors the delays between the request access and when the request is fulfilled. 

FTP Monitoring:

File Transfer Protocol (FTP) acts as a connector between the computer and a server for file transfers. The FTP requests data from server-based downloads and the network delivers it.

ICMP Monitoring:

When a device in the network web is subjected to an error, it depends on the Internet Control Management Protocol (ICMP) to generate messages to depict error. It shows the messages to devices the requests have originated from, such as the website or file.

POP3, IMAP, and SMTP Monitoring:

In the case of incoming messages or a request, post office protocol 3 (POP3) or Internet Message Access Protocol (IMAP) enables the native mail servers to receive and stock emails. For the outgoing messages, Simple Mail Transfer Protocol (SMTP) can be implemented for monitoring as it guarantees the delivering of the messages. The three protocols are more often used in conjunction with each other, to enable the verification of incoming and outgoing emails immediately.
