Telecommunications Infrastructure for Electronic Delivery 3
Telecommunications Infrastructure for Electronic Delivery 3 SUMMARY The telecommunications infrastructure is vitally important to electronic delivery of Federal services because most of these services must, at some point, traverse the infrastructure. This infrastructure includes, among other components, the Federal Government’s long-distance telecommunications program (known as FTS2000 and operated under contract with commercial vendors), and computer networks such as the Internet. The tele- communications infrastructure can facilitate or inhibit many op- portunities in electronic service delivery. The role of the telecommunications infrastructure in electronic service delivery has not been defined, however. OTA identified four areas that warrant attention in clarifying the role of telecommunications. First, Congress and the administration could review and update the mission of FTS2000 and its follow-on contract in the context of electronic service delivery. The overall perform- ance of FTS2000 shows significant improvement over the pre- vious system, at least for basic telephone service. FTS2000 warrants continual review and monitoring, however, to assure that it is the best program to manage Federal telecommunications into the next century when electronic delivery of Federal services likely will be commonplace. Further studies and experiments are needed to properly evaluate the benefits and costs of FTS2000 follow-on options from the perspective of different sized agencies (small to large), diverse Federal programs and recipients, and the government as a whole. Planning for the follow-on contract to FTS2000 could consider new or revised contracting arrangements that were not feasible when FTS2000 was conceived. An “overlapping vendor” ap- proach to contracting, as one example, may provide a “win-win” 57 58 I Making Government Work situation for all parties and eliminate future de- national infrastructure will be much stronger if bates about mandatory use and service upgrades. -

CS5865 Laboratory #1 Notes File Transfer Protocols
1 CS5865 Laboratory #1 Notes File Transfer Protocols - An Overview Dr. B.J. Kurz XMODEM (Ward Christensen, 1970), one of the earliest ‘industry standard’ file transfer protocols in the public domain. HDX operation, character (byte)-oriented, fixed-length 128-byte blocks, 8-bit characters (bytes), 8-bit BCC = sum-mod256, stop-wait ARQ, block counts, binary data capability. Poor error detection capability, typically 95%. data block format: SOH/count/1’s compl. count/ user data/BCC control block format: ACK or NAK (or C), EOT Several later versions of XMODEM are in use: XMODEM-CRC same as regular XMODEM above except uses 8-bit BCC = CRC-8 (some implementations use 16-bit BCC = CRC-16). Better error detection capability, typically 99.97% (for CRC-8). Some versions negotiate the error character generation method: the sender first tries sum- mod256 BCC, then switches to CRC-8 BCC after three unsuccessful attempts indicated by NAKs from the receiver. XMODEM-1K same as XMODEM-CRC except uses 1024-byte blocks for better throughput (fewer line- turn-arounds), but slightly degraded error detection performance. WXMODEM a sliding-window version of XMODEM. Group size is fixed as 4 blocks. Much improved throughput. FDX capable lines needed if continous-ARQ error recovery used. YMODEM (Chuck Forsberg) a variation of XMODEM-1K. Supports two block lengths of 128 bytes and 1024 bytes, uses 2-byte CRC-16, excellent error detection capability, typically 99.99%. KERMIT (Frank de Cruz, Columbia Univ. Comp. Center, N.Y), most popular file transfer protocol, copyrighted, over 200 implementations for various systems. This is a comprehensive 2 remote communications package including terminal emulators, storage-to-storage transfer, not only a file transfer protocol. -
Application Research and Evaluation Methods of Instant Messaging Software
International Journal of Multimedia and Ubiquitous Engineering Vol.11, No.7 (2016), pp.279-290 http://dx.doi.org/10.14257/ijmue.2016.11.7.28 Application Research and Evaluation Methods of Instant Messaging Software Sun Beibei Zibo Vocational Institute, Zibo, China, 255314 [email protected] Abstract With the rapid development of computer and communication technology, instant messaging software has become more and more important communication platform, but because of the diversity of the instant communication software, there have not unified specification management, lack of evaluation research for the system. Aiming at finding instant messaging software how to affect the use factors of the user, this paper uses the hierarchy analytic process (hap) and Delphi method, established the application evaluation system of instant messaging software, the usage of instant messaging software and services function be researched. Keywords: Instant messaging software; Delphi method; Hierarchy Analytic process (hap); Evaluation system 1. Introduction Instant messaging (IM) refers to a business that can carry on the Internet information to send and receive instantly, communication instantly [1]. Since 1998, IM obtained the swift and violent development, its function also more and more perfect, such as have blogs, search, music, games, etc. IM started only simple chat, now it has developed into a comprehensive information platform, integrated with news and information, communication, electronic commerce, entertainment, search, office collaboration and enterprise customer service, etc. all kinds of information. E-mail as a communication tool, but it has its own disadvantages, such as ductility flawed, however IM just make up for the shortcomings, makes the terminal capable of communications at any time, contact at any time to view the status information. -

Trojans and Malware on the Internet an Update
Attitude Adjustment: Trojans and Malware on the Internet An Update Sarah Gordon and David Chess IBM Thomas J. Watson Research Center Yorktown Heights, NY Abstract This paper continues our examination of Trojan horses on the Internet; their prevalence, technical structure and impact. It explores the type and scope of threats encountered on the Internet - throughout history until today. It examines user attitudes and considers ways in which those attitudes can actively affect your organization’s vulnerability to Trojanizations of various types. It discusses the status of hostile active content on the Internet, including threats from Java and ActiveX, and re-examines the impact of these types of threats to Internet users in the real world. Observations related to the role of the antivirus industry in solving the problem are considered. Throughout the paper, technical and policy based strategies for minimizing the risk of damage from various types of Trojan horses on the Internet are presented This paper represents an update and summary of our research from Where There's Smoke There's Mirrors: The Truth About Trojan Horses on the Internet, presented at the Eighth International Virus Bulletin Conference in Munich Germany, October 1998, and Attitude Adjustment: Trojans and Malware on the Internet, presented at the European Institute for Computer Antivirus Research in Aalborg, Denmark, March 1999. Significant portions of those works are included here in original form. Descriptors: fidonet, internet, password stealing trojan, trojanized system, trojanized application, user behavior, java, activex, security policy, trojan horse, computer virus Attitude Adjustment: Trojans and Malware on the Internet Trojans On the Internet… Ever since the city of Troy was sacked by way of the apparently innocuous but ultimately deadly Trojan horse, the term has been used to talk about something that appears to be beneficial, but which hides an attack within. -
The Kermit File Transfer Protocol
THE KERMIT FILE TRANSFER PROTOCOL Frank da Cruz February 1985 This is the original manuscript of the Digital Press book Kermit, A File Transfer Protocol, ISBN 0-932976-88-6, Copyright 1987, written in 1985 and in print from 1986 until 2001. This PDF file was produced by running the original Scribe markup-language source files through the Scribe publishing package, which still existed on an old Sun Solaris computer that was about to be shut off at the end of February 2016, and then converting the resulting PostScript version to PDF. Neither PostScript nor PDF existed in 1985, so this result is a near miracle, especially since the last time this book was "scribed" was on a DECSYSTEM-20 for a Xerox 9700 laser printer (one of the first). Some of the tables are messed up, some of the source code comes out in the wrong font; there's not much I can do about that. Also (unavoidably) the page numbering is different from the printed book and of couse the artwork is missing. Bear in mind Kermit protocol and software have seen over 30 years of progress and development since this book was written. All information herein regarding the Kermit Project, how to get Kermit software, or its license or status, etc, is no longer valid. The Kermit Project at Columbia University survived until 2011 but now it's gone and all Kermit software was converted to Open Source at that time. For current information, please visit the New Open Source Kermit Project website at http://www.kermitproject.org (as long as it lasts). -

Imperial College of Science and Technology, University of London, Department of Computing. HIGH EFFICIENCY, CHARACTER-ORIENTED, LOCAL AREA NETWORKS by Martin Cripps This thesis is submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy and the Diploma of Imperial College of Science and Technology, January 1988. For Clare Attempt the end His reasons are as two grains of wheat but never stand to doubt hid in two bushels of chaff. nothing's so hard You shall seek all day ere you find them but search and when you have found them will find it out they are not worth the search. Robert Herrick (1591-1674) William Shakespeare (1564-1616) 1 ABSTRACT This thesis explores the problem of interconnecting character-oriented devices over local area networks by investigating significant aspects of hardware, software, protocol and operational factors. It proposes effective and efficient solutions which were tested during a full-scale experiment The results of that experiment demonstrate convenient, cost-effective and reliable operation. The novelty of this investigation arises from its character-oriented approach. Much work has been carried out by others on local area networks which transfer blocks of data efficiently, however, a large majority of installed devices operate on a character-by-character basis and will continue so to do for some considerable time. This study is approached through analysis of the low efficiency of international standard networks for this class of device which defines the scope of this work. An original analysis of the potential mechanisms which can be used to give high efficiency and low delay for this class of transfer is then derived.
