Table 3-14 Local Congestion Options Elements
| Element | Description |
|---|---|
| Maximum SS7 Process CPU Utilization |
The SS7 process is responsible for all SS7 processing on an MP. Thresholds for minor, major and critical alarms are based on a fixed percentage of this maximum value. Default: 90% |
| Maximum Ingress Message Rate |
The ingress message rate measures the data messages (SI > 0) per second that the MP receives from the network. Thresholds for minor, major and critical alarms are based on a fixed percentage of this maximum value. Default: 15,000 msgs/sec. |
| Maximum PDU Buffer Pool Size for ANSI |
A Protocol Data Unit (PDU) buffer is allocated for each ANSI message that arrives at an MP and is de-allocated when message processing completes. Thresholds for minor, major and critical alarms are based on a fixed percentage of this maximum value. Default: 11000 PDUs |
| Maximum PDU Buffer Pool Size for ITUI/ITUN/ITUN24 |
A Protocol Data Unit buffer is allocated for each ITUI message that arrives at an MP and is de-allocated when message processing completes. Thresholds for minor, major and critical alarms are based on a fixed percentage of this maximum value. Default: 11000 PDUs |
| Maximum SCCP Stack Event Queue Size |
The internal event queue to the SCCP Stack which is responsible for all SCCP sublayer processing. Thresholds for minor, major and critical alarms are based on a fixed percentage of this maximum value. Default: 4,000 events |
| Maximum M3RL Stack Event Queue Size |
The internal event queue to the M3RL stack, which is responsible for all M3RL non-management (SI > 0) processing. Thresholds for minor, major and critical alarms are based on a fixed percentage of this maximum value. Default: 4,000 events |
| Maximum M3RL Network Management Event Queue Size |
The internal event queue to M3RL Network Management which is responsible for all M3RL management (SI = 0) processing. Thresholds for minor, major and critical alarms are based on a fixed percentage of this maximum value. Default: 1000 events |
| Maximum M3UA Stack Event Queue Size |
The internal egress event queue to the M3UA Stack which is responsible for all M3UA Stack processing. Thresholds for minor, major and critical alarms are based on a fixed percentage of this maximum value. Default: 2,000 events |
| Maximum SCTP Single Association Writer Queue Size |
The internal egress event queue to an SCTP Association Handler which is responsible for all non-Linux SCTP sublayer processing for a individual SCTP association. Thresholds for minor, major and critical alarms are based on a fixed percentage of this maximum value. Default: 1,000 events |
| Maximum SCTP Aggregate Association Writer Queue Size |
The internal egress event queue used to limit the maximum number of egress messages queued on all SCTP Association Handler Threads. Thresholds for minor, major and critical alarms are based on a fixed percentage of this maximum value. Default: 10,000 events |
| CL1 Message Treatment - Normal |
Percentage of ingress messages that receive normal processing treatment when the local MP congestion level is CL1. Default: 80% |
| CL1 Message Treatment - Discard & Respond |
Percentage of ingress messages that are discarded and an SCCP UDTS/XUDTS response is sent (when requested by the originator) when the local MP congestion level is CL1. Default: 10% |
| CL1 Message Treatment - Discard Only |
Percentage of ingress messages that are discarded without any further processing when the local MP congestion level is CL1. Default: 10% |
| CL2 Message Treatment - Normal |
Percentage of ingress messages that receive normal processing treatment when the local MP congestion level is CL2. Default: 70% |
| CL2 Message Treatment - Discard & Respond |
Percentage of ingress messages that are discarded and an SCCP UDTS/XUDTS response is sent (when requested by the originator) when the local MP congestion level is CL2. Default: 10% |
| CL2 Message Treatment - Discard Only |
Percentage of ingress messages that are discarded without any further processing when the local MP congestion level is CL2. Default: 20% |
| CL3 Message Treatment - Normal |
Percentage of ingress messages that receive normal processing treatment when the local MP congestion level is CL3. Default: 60% |
| CL3 Message Treatment - Discard & Respond |
Percentage of ingress messages that are discarded and an SCCP UDTS/XUDTS response is sent (when requested by the originator) when the local MP congestion level is CL3. Default: 0% |
| CL3 Message Treatment - Discard Only |
Percentage of ingress messages that are discarded without any further processing when the local MP congestion level is CL3. Default: 40% |
