Question 2

An LTM device is load balancing telnet and ssh applications in a client/server environment experiencing significant packet delay.

Which setting in the TCP profile should reduce the amount of packet delay?

    Correct Answer: B

    Disabling Nagle's Algorithm reduces the amount of packet delay in environments where applications like telnet and ssh which are sensitive to latency are being used. Nagle's Algorithm attempts to minimize the number of small packets on the network by combining a number of small outgoing messages and sending them all at once. While this is useful for reducing network congestion, it can introduce latency on connections where immediate transmission of small messages is preferred.

Discussion
gasukoOption: B

Nagle's algorithm is used to optimize the data transfer by consolidating multiple small request bytes into a single TCP segment so that the ratio of header data to payload is more efficient.

GVKDOption: B

B - Correct. A TCP profile setting such as Slow Start or Nagle's Algorithm can introduce latency when this type of traffic is being processed. https://my.f5.com/manage/s/article/K7399
