“…In Liao et al and Wang et al, if the network is overloaded, the 503 responses are delayed; then, the entity reacts with a lag. In Khazaei and Mozayani, a window‐based end‐to‐end mechanism is offered to control and manage overload in SIP networks. Holonic multiagent system is used by the due method and named window‐based holonic overload control (WHOC).…”

“…When offered load is greater than the network capacity, HOC presents adequate and relatively constant goodput. The reasons are as follows: in WHOC, window size is determined based on a negotiation and prediction process . Because these two processes are approximate, there is a slight inherent error in allocating windows to edge servers.…”

“…This algorithm calculates the window size based on previous observations. Therefore, entering extra offered load to the network is not allowed . In HOC, the superholons react quickly to a sudden increase in the offered load and control it from the sources.…”

Summary Session initiation protocol (SIP) is a widely used standard protocol for multimedia applications and IP multimedia subsystems. Internet protocol multimedia subsystem was introduced by the 3GGP signaling foundation as part of a set of next generation network architectures. Despite having useful practical features, SIP does not have suitable mechanisms to handle overload. This challenge creates a sharp drop in quality of service for next generation network users. Because a distributed SIP network is a complex system composed of subsystems interacting with one another, multiagent system is an appropriate method to model network interactions and to solve overload in SIP networks. In this paper, holonic organization is applied to reduce the multiagent system complexity in modeling a large SIP network. Holonic organization is a hierarchical structure in which each holon covers a geographical area of the SIP network at the first level. At the second level, upper‐level holons control the first‐level holons, and so on. Overload control is achieved by communication and the exchange of knowledge between the intelligent holons. Experimental results show that the proposed method prevents overload in the SIP network. The method also increases total throughput, reduces delay, and considers fairness in the SIP network.
