One segment of the DDN, the MILNET, will include 250 packet switching nodes by the end of 1987 and as many as 700 by 1991. One obstacle that must be overcome to allow this growth is the overhead associated with the current ARPANET dynamic routing mechanism. Both link utilization due to routing updates and routing computational load are roughly proportional to network size. This paper presents three approaches to reducing routing overhead and includes both modifications to the existing routing scheme and a design for a hierarchical extension.","PeriodicalId":126184,"journal":{"name":"MILCOM 1986 - IEEE Military Communications Conference: Communications-Computers: Teamed for the 90's","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134310491","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 results show the sensitivity of an unprotected radio to small changes in amplitude distortion of the received signal. Static m-curve signatures are also presented. The need to simulate the dynamics of frequency selective fading is described. Small changes to the simulator which will provide such dynamic operation are planned.","PeriodicalId":126184,"journal":{"name":"MILCOM 1986 - IEEE Military Communications Conference: Communications-Computers: Teamed for the 90's","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121960729","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}

This paper illustrates the generality of burst switch hardware and software architectures that makes interfacing to two complex military terminations--the SB-3614 Tactical Switchboard and the Digital Nonsecure Voice Terminal (DNVT)--nearly as straightforward as to interfacing an ordinary voice telephone. Brief descriptions of the SB-3614 and the DNVT are given. The elements of distributed control in burst switch networks are described as principal factors in the architecture. The same basic port hardware configuration, now in discrete logic for experimental demonstration, is used for all port types, with only the electrical interfaces differing among them. Port software is written in a switching-oriented language and employs universal command messages for interprocessor communications. Partitioning of the port software into processes common to all interfaces and those unique to a specific interface simplifies software implementation. The architectural approach makes it possible to specify and incorporate future interfaces with relative ease.","PeriodicalId":126184,"journal":{"name":"MILCOM 1986 - IEEE Military Communications Conference: Communications-Computers: Teamed for the 90's","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129562403","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}

It is shown how ionospheric measurements from a network of ionospherit sounders can be used to update sunspot number or solar 10.7 cm flux inputs to a climatological MUF prediction model, MINIMUF in this case, which is then used to predict MUFs on paths throughout the region. Analysis of mid-latitude oblique-incidence sounder data sets indicates the advantage gained from single-path sounder updates of flux for MUF predictions on adjacent paths. Under specified conditions a further dramatic improvement in MUF prediction accuracy is found from spatial interpolation of sounder-updated flux values. MUF prediction accuracies within 0.5 MHz are obtained for fairly modest sounder network deployments, in which the sounder midpath point distributions and updating frequency satisfy particular requirements.","PeriodicalId":126184,"journal":{"name":"MILCOM 1986 - IEEE Military Communications Conference: Communications-Computers: Teamed for the 90's","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124565533","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}

In view of the computational time requirements, ultimately the topological design cost of such large-scale networks would grow exponentially with the size of the network. Therefore, efficient procedures for the cost-effective design and operation of large-scale networks are required. In this paper, a multi-level hierarchical approach is presented for the topological design of a large-scale communication network employing both terrestrial and satellite links. Given the large-scale nodal switching computer locations, such nodes are decomposed into an M-level Hierarchical clustering (MHC) structure. Then, an M-level Hierarchical Topological (MHT) structure is constructed over the MHC structure. Finally, an M-level Hierarchical Routing (MHR) scheme is presented for routing the messages between any source-destination node-pair. Also, an expression for the average time delay of a message in an M-level hierarchically clustered and topologically structured communication network is given.","PeriodicalId":126184,"journal":{"name":"MILCOM 1986 - IEEE Military Communications Conference: Communications-Computers: Teamed for the 90's","volume":"367 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115275934","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 algorithm has a very simple implementation and it allows evaluation of the probability of outage for different modulation techniques.
