The developed system is co-designed with both hardware and software to optimize an architecture of a router for highly functional traffic engineering (TE). To speed up the shortest path calculation, we employ a dynamically reconfigurable processor, IPFlex DAPDNA-2, as a hardware off-loader, and newly structured a novel high-speed parallel shortest path algorithm, called MPSA (Multi-route Parallel Search Algorithm). The proposed algorithm consists of simple processing, in which multiple paths are simultaneously searched by multiple processor element (PE) of DAPDNA-2. Therefore, it reduces the execution time of shortest path calculation to 2.8% compared with the popular shortest path algorithm, Dijkstrapsilas algorithm. Our prototype works together with a famous software-based router, GNU Zebra, on commodity Linux PC. The proposed architecture and prototype system can be applied to future network sophisticated TE.","PeriodicalId":130484,"journal":{"name":"2008 International Conference on High Performance Switching and Routing","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132822977","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}

Its topologic structure is such that electronic edge nodes are always connected to each other through a single core switch, and that the core switches are disconnected. The aim is to simplify the traffic engineering and the upgradeability of core networks. In its regular form, this architecture suffers from high fiber cost and low utilization. A recent work tackles the problem of directly designing a quasi-regular composite-star structure, showing that the network cost can get more than halved and that the resources utilization can be significantly improved. In this paper, we compare the quasi-regular composite-star structure to classical irregular multi-hop structures. We show that increasing the weight of a propagation delay virtual cost in the design dimensioning objective function, multi-hop core networks tend to assume a quasi-regular composite-star like topologic structure, with a few core fibers. This suggests that such an architecture is the natural solution whether length-dependent additive costs are considered as part of the design dimensioning objective.","PeriodicalId":130484,"journal":{"name":"2008 International Conference on High Performance Switching and Routing","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132284561","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}

Efficient broadcasting, however, is one of the main problems facing dynamic channel assignment. It is easy to send broadcast packets in a network that is always connected due to the broadcast property of wireless channel. The broadcast property, however, may be unavailable when the radios on nodes can dynamically switch to different channels. In this paper, we present a scheme to support efficient broadcasting in interface switching wireless networks, where the nodes demand channel reassignment whenever they start new communications. In these scenarios, traditional broadcasting protocols do not work owing to the absence of permanent connections. One advantage of our proposed scheme is that it does not need additional radio or special channel to transmit broadcast packets. Second, it reduces the broadcast redundancy by establishing a broadcast tree that minimizes the number of relay nodes. NS2 results show that the proposed broadcast ensures that the network achieves better performance and adapts quickly to flows change.","PeriodicalId":130484,"journal":{"name":"2008 International Conference on High Performance Switching and Routing","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114708436","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}
