However, such mechanisms usually supervise the bandwidth consumption of per-flow, and are good for nothing while P2P flows dominate the traffic of Internet. In this paper, we propose a Token-Based Congestion Control, which limits the access token resource consumed by every subscriber, and provides substantial fairness in P2P networks. In this congestion control system, there are three important devices: core routers, edge routers, terminals. Core routers measure congestion level, and convey it to terminals along with dataflows. Terminals label the Token- Level on sent packets according to the Congestion-Index in the transport path, and regulate the average speed of output tokens, which are the multiplication of the packet size and the Token-Level. Edge routers police the input token rate of every terminal. We present simulations and analyses on the performance of this approach at last.","PeriodicalId":417810,"journal":{"name":"2008 First ITU-T Kaleidoscope Academic Conference - Innovations in NGN: Future Network and Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130590346","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}

The state-of-the-art in co-ordination between different (types of) standards bodies is discussed, and some improvements to the current situation are proposed. SSBs need to be flexible enough to constantly adapt to their stakeholders needs. Division of labour and improved transposition processes might help improve the current situation.

The architecture follows a model more similar to Internet open architecture than to IMS: it provides to the end user a clear interface that allows it to request (without changing its application signaling protocol) which kind of service is required, regardless of the service provider particular policies (meeting regulators' and Internet users' net neutrality requirement). This allows the network operator to take advantage of the new Internet Services as the driver for a new commercial offer based on advanced connectivity to the end user.

The existing flow control scheme adopted by IrSimple protocol consumes a considerable amount of energy and resources by retransmitting large sized Information frame in case the receiving secondary station remains busy due to handling other tasks and therefore can not send the acknowledgement of received frames. In our previous work, we proposed an efficient flow control scheme which effectively reduces the redundant data retransmissions by using receiver ready (RR) supervisory frames and assumed all the frames are received error free during flow control procedure. In this paper, we examine in detail all possible cases where Information frames or Supervisory frames may be lost at different stages of flow control to investigate the effectiveness of our proposed flow control scheme. Furthermore, we investigate the long distance capability of current IrDA links which is another future challenge to enhance IrSimple protocol applications.","PeriodicalId":417810,"journal":{"name":"2008 First ITU-T Kaleidoscope Academic Conference - Innovations in NGN: Future Network and Services","volume":"74 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120981082","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}

Optical packet switches with many-wavelength packets can be constructed with reasonable number of optical switches and FDLs (fiber delay lines) of reasonable lengths, in which switches can be controlled electrically with header information encoded in a few wavelengths to route each packet to a proper FDL or an output port. Standardization is important for format of many-wavelength packets, because they will be used at the backbone beyond multiple network operators purely optically without being converted to electric packets.","PeriodicalId":417810,"journal":{"name":"2008 First ITU-T Kaleidoscope Academic Conference - Innovations in NGN: Future Network and Services","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130328099","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}

Within service management admission control has been recognized as a convenient mechanism to provide high-quality communication by ensuring resources availability. It represents a meaning in fulfilling the contracted service level agreement (SLA) between the user and the network provider. This paper provides a thorough analysis on different classification approaches for admission control techniques, while identifying their characteristics, differences and analogies. Currently, there is no standardized classification of admission control in the standards bodies. It further gives a more detailed analysis on the measurement-based admission control based on performance analysis, and introduces an admission control approach based on measurements. The performance of this algorithm is illustrated through simulation results.","PeriodicalId":417810,"journal":{"name":"2008 First ITU-T Kaleidoscope Academic Conference - Innovations in NGN: Future Network and Services","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133538825","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}
