A system of standard packet sizes and letter codes (borrowed from Y.1564) is used
for all regimes. These are shown below:
Code
Packet Size (bytes)
a
64
b
128
c
256
d
512
e
1024
f
1280
g
1518
2048
4000
6000
8000
10000
h
MTU - the service MTU size
u
User - a user-defined size
Packet sizes may be entered as letter codes or (for the fixed sizes) as numbers. In
keeping with Y.1564, multiple sizes may be entered as a string of letter codes with
no space between them. They may also be entered as a list of numbers, separated
by commas. For example,
abc
is equivalent to
64,128,256
.
Note that the jumbo sizes have no letter codes and must be entered as numbers.
