Question 1 |
On a TCP connection, current congestion window size is Congestion Window=4 KB. The window size advertised by the receiver is Advertise Window=6 KB. The last byte sent by the sender is LastByteSent=10240 and the last byte acknowledged by the receiver is LastByteAcked=8192. The current window size at the sender is
2048 bytes | |
4096 bytes | |
6144 bytes | |
8192 bytes |
Question 1 Explanation:
Corrent sender window
= min (4KB, 6KB)
= 4KB
= min (4KB, 6KB)
= 4KB
