set service

Chapter 2 Command Descriptions 119

nodelay={on|off}

Used to allow unacknowledged or smaller than maximum segment sized

data to be sent.

Note: The “nodelay” option disables Nagle’s algorithm, which is on by

default, for some TCP services. The purpose of Nagle's algorithm is to

reduce the number of small packets sent. Briefly Nagle's algorithm says

to hold on to outgoing data when there is either unacknowledged sent

data or there is less than maximum segment size (typically around 1500

bytes for Ethernet) worth of data to be sent. It does a good job at keeping

transmission efficient, but there are times where it is desirable to disable

it.

Examples Disable service

set service

Displaying an entry in the service table

In this example, the set service command displays a range of entries in the

service table.

set service range=2-4

Allow outgoing data that is either unacknowledged or is less than maximum

segment size
