The need to reduce space operations costs, the expected availability of distributed communications architectures within space vehicles, and the design of increasingly complex space constellations have generated civil and military requirements to provide functions such as end-to-end networking, data protection, reliable delivery and file handling. Under a joint technical effort by the US Department of Defense (DoD) and the National Aeronautics and Space Administration (NASA), space data communications protocols are being developed to provide these functions. The capabilities needed to be provided in these protocols are very much influenced by space communications constraints in areas such as computing resources, data rates, contact time, delay and transmission errors. These new space protocols have been submitted to both the US government and the Consultative Committee for Space Data Systems (CCSDS) for approval as standards. The commercial space, military tactical, and wireless personal communications communities, which have system and environment constraints similar to those encountered in space data communications, may also benefit from the technology of these space protocols.","PeriodicalId":351392,"journal":{"name":"MILCOM 97 MILCOM 97 Proceedings","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123300231","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}

These technology improvements, using commercial-off-the-shelf (COTS) and/or government-off-the-shelf products, is part of a long term Department of Defense cost reduction strategy for modernizing currently fielded tactical systems. The goal is to acquire commercially based C4I systems that can be expeditiously deployed to warfighting elements. This broad strategy allows DOD services and agencies to deploy current, standards based, commercial technologies with a minimum of up-front development effort and associated costs. During JWID, high speed digital services were extended beyond the traditional DISN boundary in support of forward deployed JTF using the state-of-the-art commercial switching equipment. The COTS products used in this demonstration served as a proof of concept for using commercial technologies for tactical multimedia applications. The network consisted of four mobile switching nodes forming a meshed backbone linking demonstration sites at MacDill AFB, Ft. Bragg, Ft. Gordon, and Shaw AFB. The enabling technologies are ATM cell switching, ISDN telephony, and transparent ATM support for legacy IP router networks. ATM switches interfaced with three types of ISDN PABXs. The PABXs in turn interoperated with a wide range of voice terminals (analog, tactical, digital, ISDN, STU-III), computer terminals, and ISDN desktop products.","PeriodicalId":351392,"journal":{"name":"MILCOM 97 MILCOM 97 Proceedings","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124735162","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}

Motorola Space and Systems Technology Group, Radio Systems Operation is currently exploring techniques to enable the application of virtual prototyping to reduce risks and cost for concept exploration, requirements analysis, design and development of military mobile distributed wireless terrestrial communications systems and networks technologies. Existing \"state of the art\" commercially available communications systems and network modeling tools do not support representation of mobile distributed wireless terrestrial communications systems and networks using distributed interactive simulation (DIS) protocols which are the current basis for development of virtual battlefield simulations. Also its uncertain when and/or whether the evolving high level architecture (HLA) standards defined by DoD will be supported by commercially available tools. Researchers in the DIS domain have focused primarily upon the communications infrastructure required to support DIS versus how they can use the DIS environment to conceptualize, analyze, design, and prototype future communications systems and networks. This paper describes a virtual prototyping methodology and toolset requirements needed to provide a virtual prototyping environment for mobile distributed wireless communications.","PeriodicalId":351392,"journal":{"name":"MILCOM 97 MILCOM 97 Proceedings","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129582219","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 Interoperability Program is an umbrella effort to develop interoperability requirements for the family of encryption products providing the security of the network infrastructure. The initial output of this effort is the Interoperability Functional Requirements Criteria. The document was created to provide guidelines and requirements on classes of security products which will operate over the evolving commercial infrastructure. It was developed by a working group including representatives from DOD and commercial companies. Encryption classes were defined at the link, network and application layers. Based upon the expected evolution of the commercial architecture approaches were developed to both provide heterogeneity of equipment and extend transparency of needed security services across all layers. Important areas of inclusion in the specification are: (1) the establishment of the Internet Security Association and Key Management Protocol (ISAKMP) as the security management protocol, (2) definition of a transition from the Security Association Management Protocol (ISAMP) to ISAKMP, and (3) the establishment of an interpretable Domain of Interpretation (DOI). Along with this, common encryption data handling and voice algorithms were defined to insure a least common denominator mode with heterogeneity between equipment.","PeriodicalId":351392,"journal":{"name":"MILCOM 97 MILCOM 97 Proceedings","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129655429","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}
