Configuring HPC/GETS Feature#EMS RAMP Configuration

The steps mentioned below are not strictly sequential. However, Ribbon recommends executing them in the order mentioned in this document.

% set profiles sipCacProfile <profile_name>
	hpcCallLimits
		maxCalls <unlimited | blockAll | 1-1000> 
		maxIngressRate <unlimited | 1-2000> 
		ingressRateInterval <1-30> 
		bucketSize <1-4000> 

For more information on configuring hpcCallLimits, refer to the section "HPC Call Limits" of the page SIP CAC Profile - CLI.

% set profiles sipCacProfile testSipCacProfile hpcCallLimits maxCalls 500 maxIngressRate 50 ingressRateInterval 10 bucketSize 32

For more information on configuring dscpProfile, refer to DSCP Profile - CLI.

% set system media mediaPortRange highPriorityPortRangeLocation bottom highPriorityPortRangeSize 10
% commit

The percentage specified as highPriorityPortRangeSize is used as the High Priority reserve for both Media Port Range (MPR) and LIF bandwidth. For more information on Media Port Range, refer to Media System - CLI.

The configuration for the parameters highPriorityPortRangeLocation and highPriorityPortRangeSize defines the High Priority Media Port Range (HPMPR) as a subset of the overall MPR. The SBC uses the configuration to quickly identify UDP packets (both media and non-media) arriving within the overall MPR, and prioritizes them while processing ingress UDP packets. For GETS/HPC applications, Ribbon recommends reserving 10% of the MPR as HPMPR. If additional SIP Signaling Ports (besides the default port 5060), and/or other Control UDP ports are within the overall MPR, Ribbon recommends configuring them within the HPMPR. Such configuration ensures that during congestion, they are prioritized while processing ingress packets.

For example, if the overall MPR is defined as 1024-65535, and the High Priority Port Range is 10% (starting with the lower limit of MPR), then the HPMPR is 1024-7475. Ribbon recommends configuring additional SIP Signaling and other Control UDP ports within the range 1024-7475. In case of congestion, such configuration ensures that while processing ingress packets, packets received at ports within the range configured for HPMPR are prioritized. Normal calls are allocated local UDP ports ranging from 7476-65535, and GETS/HPC calls are allocated local UDP ports ranging from 1024-7475.

% set profiles services hpcCallProfile <profile_name> 
	dscp <egress | ingress> 
	useRecvdValue <disabled | enabled>

The SBC supports configuring up to 256 HPC Call Profiles.

For more information on configuring hpcCallProfile, refer to HPC Call Profile - CLI.

The prerequisite step is OPTIONAL; implement it based on the configuration requirement.

For more information on configuring hpcCallProfile queue, refer to HPC Call Profile - CLI.

For more information on configuring HPC callQueuing at a global level, refer to Call Queuing - Global - CLI.

Do not enable HPC call queuing for ingress and egress trunk groups simultaneously.

The rph configuration mentioned above shows only a minimal configuration. It assumes default values for all other parameters and flags. For more information on configuring hpcCallProfile rph, refer to HPC Call Profile - CLI.
