CDM-570/570L Satellite Modem with Optional IP Module
Ethernet IP Module Interface
•
Any packet that does not meet a QoS Rule is assigned to the Default Rule and is assigned
a Priority of 9
Maximum Bandwidth – This can also be assigned to a flow to restrict the Maximum Bandwidth
that any particular flow will utilize; otherwise, the default of no bandwidth restriction can be
selected.
Filtering – QoS also allows specific flows to be designated as "filtered," so the IP Module will
discard traffic that is otherwise not wanted for forwarding over a satellite link.
QoS Rule Hierarchy – It is quite possible to have traffic that meets the definitions of several
QoS Rules. All traffic will be classified into the first QoS Rule that is a match, or fall into the
Default Rule. The most specific QoS Rule will always be first. For example, a QoS Rule that
identified a Source and Destination IP Address would be assigned ahead of a rule that just defined
RTP protocol. QoS Rules that have the same amount of variables defined are sorted as follows:
1. Having a Protocol defined:
Protocol Priority
CTRX
FTP
HTTP
ICMP
IP
N-IP
ORCL
RTP
RTPS
SAP
SMTP
SNMP
SQL
TCP
TELN
UDP

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).
