Automatic Alarm-giving on Detecting Network Abnormality: a SIP-based Approach

Abstract

本文提出一個以SIP語音服務為基底的自動警示系統SIP-AG。當SIP-AG偵測到網路服務有異常狀況時，可根據網管人員的需求選擇以手機或網路電話來接收由SIP-AG發出的語音警訊。網管人員收到警訊後必須回覆特定的代碼，以完成警示程序；否則系統會持續不斷地重送警訊。本文提供壓力測試的數據，可作為系統建置和評估的參考。

SIP, the session initiation protocol, is a new signaling protocol developed to set up, modify, and tear down voice session over the Internet. In this paper, we present a SIP-based alarm-giving system named SIP-AG. On detecting network abnormality, SIP-AG can make a phone call to the on-duty administrator, and play the pre-recorded warning message in the call. We implement the SIP-AG in Asterisk, and give the alarm-giving overhead, as well.
