Together, they form theInternet protocol suite, also known as TCP/IP.
On the destination computer, TCP reassembles the packets and forwards the message to the intended target software.
For example, web browsers use HTTP on top of TCP for communication with web servers.
TLS/SSL are cryptographic protocols for secure communication over computer networks.
They are based on the exchange of X.509 certificates and public keys for encrypting and decrypting messages.
Digital certificates are issued by a certificate authority (CA) trusted by both parties involved in the communication.
As a transport layer protocol, TCP uses ports, which are tool-specific endpoints in online grid communication.
When added to an IP address, the port number completes the address for a TCP/IP connection.
Port numbers are bound to specific processes on the destination computer.
Port numbers are 16-bit unsigned integers ranging from 1 to 65535.
Some well-known ports are reserved for the most common services.
This helps you monitor both the reachability and the performance of your critical web connection services.
Long timeouts can greatly affect the quality of services you provide to your customers.
If the server uses TLS/SSL security, it is also important to monitor the certificate expiration date.
