An accurate experimental analysis of the main GMPLS features, such as the different reliability solutions, is then required. In this paper, we present the experimental implementation of different reliability solutions in the Metrocore/VESPER field trial, the high-performance network infrastructure located in Pisa, Italy. Protection and restoration schemes are investigated both at the IP/MPLS and physical layer.","PeriodicalId":299180,"journal":{"name":"First International Conference on Testbeds and Research Infrastructures for the DEvelopment of NeTworks and COMmunities","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128197577","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}

Given the challenges that have arisen in construction, deployment and maintenance of wireless mesh networks, we outline a broad experimental research program in the area of medium-to-large scale community wireless networks. Our research is conducted in the context of an operational community network built in our test bed laboratory with continual plans to expand to the town of Troy, NY (up to hundreds of nodes in a 1-2 mile radius around RPl campus). Leveraging Global Positioning System (GPS) receivers and Geographic Distributed Addressing (GDA), a novel and intuitive addressing assignment, geographic-based forwarding algorithms such as GPSR and TBF can be easily tested and traffic engineering theories implemented in a real-world environment. Our paper documents several design considerations and contributions in implementing community wireless networks including autoconfiguration, addressing structure and antenna characteristics among other items, in addition to describing our novel test bed lab where RF effects of distances of thousands of meters can be simulated with server, antenna and variable attenuator clusters.","PeriodicalId":299180,"journal":{"name":"First International Conference on Testbeds and Research Infrastructures for the DEvelopment of NeTworks and COMmunities","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134284978","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 Global X-Bone (GX-Bone) augments the X-Bone software system, enhancing its coordination mechanisms to support deployment of local overlays to world-wide, shared infrastructure. The GX-Bone is based on the X-Bone's Virtual Internet Architecture which extends the Internet for both concurrent, parallel and recursive overlays and provides decentralized, automated deployment and management. GX-Bone supports host visualization through the NetFS file system, granting individual users compartmentalized access and control of host and router configuration and the DataRouter extension to IP loose source routing that supports application control of network-layer forwarding. GX-Bone can be installed on user-modified kernels, uniquely supporting both conventional kernel-level protocol development and coordinated global infrastructure sharing.","PeriodicalId":299180,"journal":{"name":"First International Conference on Testbeds and Research Infrastructures for the DEvelopment of NeTworks and COMmunities","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127755223","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}
