We argue that offensive, proactive, system-level adaptation deserves not less attention. If a distributed multimedia system cares for overall, end-to-end quality of service then it should provide a meaningful combination of both. We introduce an adaptive multimedia server (ADMS) and a supporting middleware which implement offensive adaptation based on a lean, flexible architecture. The measured costs and benefits of the offensive adaptation process are presented. We introduce an intelligent video proxy (QBIX), which implements defensive adaptation. The cost\/benefit measurements of QBIX are presented elsewhere [1]. We show the benefits of the integration of QBIX in ADMS. Offensive adaptation is used to find an optimal, user-friendly configuration dynamically for ADMS, and defensive adaptation is added to take usage environment (network and terminal) constraints into account.<\/jats:p>","DOI":"10.2298\/csis0401045t","type":"journal-article","created":{"date-parts":[[2009,3,27]],"date-time":"2009-03-27T07:28:13Z","timestamp":1238138893000},"page":"45-73","source":"Crossref","is-referenced-by-count":3,"title":["Offensive and defensive adaptation in distributed multimedia systems"],"prefix":"10.2298","volume":"1","author":[{"given":"Roland","family":"Tusch","sequence":"first","affiliation":[{"name":"Institute of Information Technology, Klagenfurt University, Klagenfurt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L\u00e1szl\u00f3","family":"B\u00f6sz\u00f6rm\u00e9nyi","sequence":"additional","affiliation":[{"name":"Institute of Information Technology, Klagenfurt University, Klagenfurt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bal\u00e1zs","family":"Goldschmidt","sequence":"additional","affiliation":[{"name":"Department of Control Engineering and Information Technology, Budapest University of Technology and Economics, Budapest"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hermann","family":"Hellwagner","sequence":"additional","affiliation":[{"name":"Institute of Information Technology, Klagenfurt University, Klagenfurt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Schojer","sequence":"additional","affiliation":[{"name":"Institute of Information Technology, Klagenfurt University, Klagenfurt"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1078","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/76.736724"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/93.682522"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/93.556538"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/MIC.2002.1036038"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1145\/306549.306582"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1023\/A:1011498424351"}],"container-title":["Computer Science and Information Systems"],"original-title":[],"language":"en","deposited":{"date-parts":[[2023,5,29]],"date-time":"2023-05-29T08:29:11Z","timestamp":1685348951000},"score":1,"resource":{"primary":{"URL":"https:\/\/doiserbia.nb.rs\/Article.aspx?ID=1820-02140401045T"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004]]},"references-count":6,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2004]]}},"URL":"https:\/\/doi.org\/10.2298\/csis0401045t","relation":{},"ISSN":["1820-0214","2406-1018"],"issn-type":[{"value":"1820-0214","type":"print"},{"value":"2406-1018","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004]]}}}
