CDM-570A/570AL Satellite Modem with Optional Packet Processor
Revision 5
Advanced Quality of Service (QoS) Option L–3 MN-CDM570A
QoS Rules having the same amount of defined variables are sorted as follows:
1. Having a Protocol defined:
Service Announcement Protocol
Simple Mail Transfer Protocol
Hypertext Transfer Protocol
Simple Network Management Protocol
Internet Control Message Protocol
Structured Query Language Protocol
Transmission Control Protocol
All Non-Internet Protocol
Real Time Protocol Signaling
2. Source IP Address or subnet defined.
3. Destination IP Address or subnet defined.
4. Source Port defined (lowest Port number first).
5. Destination Port defined (lowest Port number first).
The IP Packet Processor will sort each QoS rule as they are added and the QoS Configuration
display will be updated to reflect the order with which rules are matched.
QoS Statistics – Every defined QoS Rule can be monitored to see the traffic flow for each
queue. These statistics display the traffic sent in each queue, the amount of dropped traffic, and
the number of Active Flows.
Protocol and Port Number Considerations – When defining QoS Rules, it is important to be
aware of specifics of the traffic for which the rule is intended. When selecting a protocol for a QoS
Rule, be aware that the IP Packet Processor allows for a very broad selection (such as IP) or a
very specific protocol. For example, RTP traffic can consist of UDP portion (for voice or video)
and a TCP portion (for RTP signaling). These could have separate QoS Rules created or all be
included in a single Rule by selecting RTP as the protocol.
