Two methods \u2013 a closed form one based on the use of the pseudo\u2010inverse matrix and an iterative one \u2013 are examined in network scenarios of varied size and connectivity under different congestion levels. In addition, a criterion based on a Bayesian approach is proposed for initializing the iterative method. It is shown that the iterative method is affected by lower estimation errors than the pseudo\u2010inverse method, and that the iterative method's performance is further enhanced by the employment of the Bayesian initialization criterion. Some tentative relationships are provided between the estimation accuracy and the network size and connectivity. The improvement in the estimation accuracy is accompanied by an even more pronounced reduction in the computational load. The use of the iterative method with Bayesian initialization requires in fact running times even two orders of magnitude lower than those needed by the pseudo\u2010inverse method, the gap being larger the larger the network and the higher the connectivity.<\/jats:p>","DOI":"10.1002\/ett.4460100504","type":"journal-article","created":{"date-parts":[[2008,9,12]],"date-time":"2008-09-12T13:50:39Z","timestamp":1221227439000},"page":"497-504","source":"Crossref","is-referenced-by-count":1,"title":["Estimation of Point\u2010to\u2010Point Traffic in Circuit\u2010Switched Networks"],"prefix":"10.1002","volume":"10","author":[{"given":"Milena","family":"Butt\u00f2","sequence":"first","affiliation":[]},{"given":"Pietro Giulio","family":"Conversi","sequence":"additional","affiliation":[]},{"given":"Maurizio","family":"Naldi","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2008,9,12]]},"reference":[{"key":"e_1_2_1_2_2","volume-title":"Routing and Dimensioning in Circuit\u2010Switched Networks","author":"Girard A.","year":"1990"},{"key":"e_1_2_1_3_2","unstructured":"N.Kim A point\u2010to\u2010point traffic estimation from trunk\u2010group and office measurements for large networks.
