As a reaction to large-scale SIP deployment experiences in the field and the need to implement high availability and reliability within these new networks, the focus of SIP extension standardization has shifted from adding new SIP signaling functionality to operational and maintenance aspects, a particular importance being attributed to overload control. Overload denotes a situation in which the traffic injected into a system exceeds the system\u2019s designed capacity. The authors present a detailed categorization of overload architectures and outline main reasons why SIP-based networks are at high risk to collapse when operating at overload. Using measurements in a real SIP infrastructure this paper compares the performance of two overload protection schemes, namely implicit and explicit overload protection, against the performance of non-protected systems. The measurement results recommend overload protection as a mandatory component of commercial SIP deployments to safeguard operation and prevent system collapse in case of overload.<\/p>","DOI":"10.4018\/ijmtie.2011100102","type":"journal-article","created":{"date-parts":[[2012,6,28]],"date-time":"2012-06-28T11:49:18Z","timestamp":1340884158000},"page":"12-27","source":"Crossref","is-referenced-by-count":1,"title":["An Architectural and Evaluative Review of Implicit and Explicit SIP Overload Handling"],"prefix":"10.4018","volume":"1","author":[{"given":"Marco","family":"Happenhofer","sequence":"first","affiliation":[{"name":"Vienna University of Technology, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joachim","family":"Fabini","sequence":"additional","affiliation":[{"name":"Vienna University of Technology, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Egger","sequence":"additional","affiliation":[{"name":"Vienna University of Technology, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Hirschbichler","sequence":"additional","affiliation":[{"name":"Vienna University of Technology, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"ijmtie.2011100102-0","doi-asserted-by":"crossref","unstructured":"Campbell, B., Rosenberg, J., Schulzrinne, H., Huitema, C., & Gurle, D.
