Title
On Locating Loss Links of Signaling Messages in SIP-Based Services
Abstract
The number of SIP-based services provided by network service providers (NSPs) is increasing. SIP allows NSPs to collect the information on traffic control and charging fees for their customer communications. Monitoring SIP signaling messages (exchanged between SIP servers and user terminals) is vital for providing stable SIP-based services. One of the keys to monitoring SIP messages is quickly to determine a fault location where SIP messages are lost. If network operators can determine that there is a fault location somewhere between SIP nodes, they can quickly treat with the fault. The existing methods require abundant computing resources to support these procedures because of inspecting all the SIP messages. This paper proposes a lightweight method for determining the location of SIP message loss by focusing on the retransmission mechanism of SIP messages. Analyzing the retransmission mechanism, we reveal that the proposed method can determine the fault location by counting the number of the retransmitted messages on the limited SIP messages. The evaluation with a mathematical model shows that the proposed method can locate loss links of SIP messages with a sufficiently low probability of failure.
