Oracle SBC Security Guide

 max-sustain-rate—maximum rate of session invitations allowed within the current window for

this constraint

 max-inbound-sustain-rate—maximum inbound sustain rate (of session invitations allowed

within the current window) for this constraint

 max-outbound-sustain-rate—maximum outbound sustain rate (of session invitations allowed

within the current window) for this constraint

 min-seizures—minimum number of seizures for a no-answer scenario

 min-asr—Enter the minimum ASR in percentage

 time-to-resume—number of seconds after which the SA (Session Agent) is put back in service

(after the SA is taken out-of-service because it exceeded some constraint)

 in-service-period—Enter the time in seconds that elapses before an element (like a session

agent) can return to active service after being placed in the standby state

 ttr-no-response—Enter the time delay in seconds to wait before changing the status of an

element (like a session agent) after it has been taken out of service because of excessive

transaction timeouts

 burst-rate-window—Enter the time in seconds used to measure the burst rate

 sustain-rate-window—Enter the time in seconds used to measure the sustained rate

Oracle recommends use of session constraints on external SIP interfaces to limit the total number of

sessions and / or traffic bursts that the combined configured session agents can handle for that service.

Additionally, having multiple public SIP interfaces defined can limit the resources a particular SIP

interface can provide based on service level agreements or the trust level of the endpoint.

Rate constraints

The rate-constraints sub-element is configurable under both the session-constraints and session-agent

configuration elements (though they are not shared). It allows configuration of rate limiting based on

specific method types. These further restrict any defined constraints of the parent, so they cannot exceed

the rates defined at the level under which they are set.

 method—the SIP method name for the method to throttle, possible values are: NOTIFY,

OPTIONS, MESSAGE, PUBLISH, REGISTER

 max-inbound-burst-rate—For the SIP method configured in the method parameter, this

number will restrict the inbound burst rate on the SIP interface.

 max-outbound-burst-rate—For the SIP method configured in the methods parameter, this

number will restrict the outbound burst rate on the SIP interface.

 max-inbound-sustain-rate—For the SIP method configured in the methods parameter, this

number will restrict the inbound sustain rate on the SIP.

 max-outbound-sustain-rate—For the SIP method configured in the methods parameter, this

number will restrict the outbound sustain rate on the SIP interface.

Each rate constraint configured for a SIP method maintains its own counters. For example, if a rate

constraint for the PUBLISH method is configured, the burst and sustain rates set for it apply only to the

PUBLISH method and not to any other methods.

The SBC captures statistics for SIP methods that have already been throttled by rate constraints for SIP

interfaces and session agents; it does not capture these statistics for the global SIP configuration. SIP

interfaces have two states: “In Service” and “Constraints Exceeded.” When any one of the constraints is

exceeded, the status of the SIP interface changes to “Constraints Exceeded” and stops accepting traffic. It

remains in that state until the time-to-resume period ends. The session constraint timers that apply to the

SIP interface are the time-to-resume, burst window, and sustain window.
