SIP faces with overload issue recently due to its popularity.  Build-in overload mechanism cannot prevent potential overload collapse effectively. Therefore, IETF SIP Overload Control (soc) Working Group is working on IETF RFC "SIP Overload Control" currently.

Redundant Retransmission Ratio Control (RRRC, implicit SIP overload control) algorithm has been quickly adopted by The Central Weather Bureau of Taiwan for their early earthquake warning system.

Round-Trip Delay Control (RTDC, implicit SIP overload control) algorithm has been recommended as White Paper by TechRepublic (CBS Interactive)

Control theorectic approaches have been applied to model the interactions between an overloaded SIP server and its upstream servers as a feedback control system in two different scenarios - Round-Trip Delay Control (IEEE ICC 2011) and Redundant Retransmission Ratio Control (IEEE Globecom 2010).

Journal paper (implicit SIP Overload Control) published by Springer Telecommunication Systems OnlineFirst this July not only conducts more theoretical analysis of Round-Trip Delay Control (RTDC) and Redundant Retransmission Ratio Control (RRRC), but also discusses how to apply RTDC algorithm to mitigate SIP overload for both SIP over UDP and SIP over TCP (with TLS).

Implicit SIP overload control solution using control theorectic approaches can be regarded as an engineering applications of control theory, see the discussion on control system design in the answers to the following two ResearchGate(RG) questions. ResearchGate is the largest social network for research scientists and engineers in the world.

RG Question #1: "What are trends in control theory and its applications in physical systems (from a research point of view)?"
https://www.researchgate.net/post/What_are_trends_in_control_theory_and_its_applications_in_physical_systems_from_a_research_point_of_view2

RG Question #2: "What are the latest problems to be solved in "control of nonlinear systems"?"
