A client needs to send 4000 bytes of data to a database server. The client divides the data into packets of 500 bytes each. The sequence number of the first packet is 3001. After 2500 bytes have been successfully sent, 2 packets are lost/failed.
Assuming TCP cumulative ACK, complete the following table:
| SL | Client Packet Sequence No. | DB Server Sequence No. | ACK Sequence No. |
Assumption:
The first 5 packets (2500 bytes) are sent successfully. Packets 6 and 7 are lost, while packet 8 arrives. The server sends a cumulative ACK for the next byte it is expecting.
Find the missing values in the table. You are free to add necessary rows if needed.
