TCP Connection in BGP πŸš€
1️⃣ Establishing the Connection

BGP must establish a TCP connection between peers using TCP port 179. Initially, BGP establishes the TCP connection before sending any BGP messages.
2️⃣ Transmission Control Block (TCB)

A router maintains a Transmission Control Block (TCB) table to store information about each TCP connection.
What is TCB?
The Transmission Control Block (TCB) is a fundamental data structure used by the TCP protocol to store information about each active TCP connection.
3️⃣ 3-Way Handshake 🀝

To establish a TCP connection, the router performs a 3-way handshake by exchanging three TCP packets with the SYN, SYN-ACK, and ACK flags set.
4️⃣ Random Source Port Number 🎲

The device initiating the TCP connection uses a random source port number, while the destination device uses the BGP port number 179.
5️⃣ Message Exchange πŸ“§

Once the TCP connection is established, the router will exchange other types of messages.
How Does TCP Select the Random Port Number? πŸ€”
1️⃣ The initiating device picks its random port number from a specific range (usually between 49152 and 65535).

2️⃣ To pick this number, it uses a method similar to rolling dice but more sophisticated. This method is called a pseudorandom number generator (PRNG). The PRNG ensures that the port number chosen is unpredictable and reduces the chances of port conflicts.

3️⃣ Algorithm Name: One common method used for generating this random port number is called the Linear Congruential Generator (LCG). LCG is like a complex mathematical formula that helps the device pick a random number quickly and efficiently.
