TCP Handshake Details | Dataford Interview Questions

What are the 3 parts of a TCP handshake?

Implement build_tcp_handshake(client_isn, server_isn). Given the initial sequence numbers for both endpoints, return the three handshake packets in order. Each packet must include its direction, flags, sequence number, and acknowledgment number. Use null for the acknowledgment number when the packet does not acknowledge prior data.

Constraints

client_isn and server_isn are integers
0 <= client_isn, server_isn <= 2^31 - 1
Return exactly three packets in handshake order
Sequence and acknowledgment arithmetic does not wrap within the test inputs

Function Signature

def build_tcp_handshake(client_isn, server_isn):

Whenever you're ready, walk me through your approach or go straight to the code. The requirements are in the Question tab.
