Tos Prioritization; Included With Traffic Prioritization - RuggedCom RuggedRouter RX1000 User Manual

TOS Prioritization

The priority of an IP packet can be derived from its Type of Service field. The TOS
field has the following format:
7
+---+---+---+---+---+---+---+---+
|
|PRECEDENCE |MD
|
+---+---+---+---+---+---+---+---+
The four TOS bits (the 'TOS field') are defined as:
MD - Minimize Delay,
MT - Minimize Throughput,
MR - Maximize Reliability,
MMC - Minimize Monetary Cost
As any (or all) of these bits may be set in a packet at a time, there are 16 possible
combinations. The router maps these combinations into the high, normal and low
priority queues as shown in the following table:
MD
