A compute server which consists of a dedicated workstation with a link to the vector processor is used to provide the vector processor service. Implementations are developed for each model and are tested using alternative transport protocols, namely TCP (transport control protocol) and UDP (user datagram protocol). Experimental results indicate that the vector processor service suffers negligible degradation due to the network communication overhead in comparison to stand-alone operation. A model based on remote execution is slightly faster than a model based on remote procedure call due to less communication overhead.<<ETX>>","PeriodicalId":274297,"journal":{"name":"Proceedings of TRICOMM `91: IEEE Conference on Communications Software: Communications for Distributed Applications and Systems","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132542688","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}

Furthermore, Montage is designed to be runtime extensible to novel media types by its users. Thus the system does not have to know ahead of time all the possible media users may want to send. The system is built on top of existing mail transport protocols for flexibility and portability. A discussion is presented of the design of the mailer along with experiences gained from its implementation.

The communications architecture (by which the authors refer to the protocols and supporting network management system) is based around the DARPA Internet Protocol suite, but with certain enhancements to support real time traffic. The CODEC runs a standard bitstream encoding of video, and this is packetized by the PC. However, this is not sufficiently flexible a protocol to traverse the Internet. The stream protocol (ST) gateway then runs two further protocols to carry the video and voice: (1) packet video protocol (PVP) and (2) voice traffic protocol (VT). Each of these is tuned to the special requirements of video and voice. To carry these in a reasonably consistent fashion, the gateways then run the ST. The performance of the system is limited mainly by the bandwidth of the first few hops of the path.<<ETX>>","PeriodicalId":274297,"journal":{"name":"Proceedings of TRICOMM `91: IEEE Conference on Communications Software: Communications for Distributed Applications and Systems","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114741371","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}
