Although both are complementary technologies, the integration of the two technologies is a non-trivial task due to architectural conflicts between multicasting and DiffServ. We propose a protocol for member join/leave in a DiffServ network that is scalable in terms of group size, network size, and number of groups. We detail our join/leave protocol for both intra-domain and inter-domain routing as well as the various different types of multicast trees (single source tree, shortest path tree, shared tree, many-to-many tree). Finally, we present simulation studies regarding the performance of our join/leave protocol.","PeriodicalId":213526,"journal":{"name":"Proceedings LCN 2001. 26th Annual IEEE Conference on Local Computer Networks","volume":"31 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130807748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SRP is a MAC layer protocol for ring based media (e.g., optical rings) that can carry IP and ATM client (prioritized) traffic (see Tsiang, D. and Suwala, G., \"The Cisco SRP MAC Layer Protocol\", RFC 2892, 2000). This protocol is one basis for the evolution of the currently standardized resilient packet ring, IEEE 802.17 (see http://www.ieee802.org/rprsg/). We develop approximative formulae for the transfer delay on a SRP ring and determine the maximum network throughputs for a traffic pattern. The formulae are instrumental in performance considerations and in quasi-validations of simulators.","PeriodicalId":213526,"journal":{"name":"Proceedings LCN 2001. 26th Annual IEEE Conference on Local Computer Networks","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126490057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
