DevOps - Step By Step Learning : Part 19 (TCP and UDP Are The Backbone of Transport Layer)
Other Parts of This Series: Part 18: DevOps - Step By Step Learning : Part 18 (NAT, PAT For Inner Private with Outer Public Network Handshaking) Part 20: DevOps - Step By Step Learning : Part 20 (Hands On Networking Commands, Practically Connect The Theory) DevOps Networking TCP & UDP (Photo Credit: Unsplash) Story: Till now Rasel explored how data move host to host over the OSI or TCP/IP model by utilizing all the parties/parts like networking devices and protocols. He understood how source and destination IPs resolved in the application layer using DHCP and DNS, respectively. Also, he tried to realize how the logical address, like IP, makes a connection with the physical address, like the MAC address, using ARP the bridge between the data link and network layers. Besides all of these, Rasel explored how do using mechanisms like NAT/PAT overcome IPv4 limitations and private-public IP mapping in the transport and network layers. All the points were served via MAC address table, routing table, ARP table/cache, NAT mapping table, etc. ...
