ConneXions now online

ConneXions – The Interoperability Report was published monthly from 1987 through 1996. The Charles Babbage Institute at the University of Minnesota has scanned the complete collection of ConneXions (117 issues) and it is now available here.

The Internet Protocol Journal is intended to serve as an informational and educational resource for engineering professionals involved in the design, development, and operation of public and private internets and intranets. It does not promote any specific products or services, but focuses on issues facing the network designer or operator. The journal carries tutorial articles ("What is...?") as well as implementation/operation articles ("How to..."). It provides readers with technology and standardization updates for all levels of the protocol stack and serves as a forum for discussion of all aspects of internetworking.

Topics include but are not limited to:

  • Access and infrastructure technologies such as: ISDN, Gigabit Ethernet, SONET, ATM, xDSL, cable, fiber optics, satellite, wireless, and dial systems.
  • Transport and interconnection functions such as: switching, routing, tunneling, protocol transition, multicast, and performance.
  • Network management, administration, and security issues, including: authentication, privacy, encryption, monitoring, firewalls, troubleshooting, and mapping.
  • Value-added systems and services such as: Virtual Private Networks, resource location, caching, client/server systems, distributed systems, network computing, and quality of service.
  • Application and end-user issues such as: E-mail, Web authoring, server technologies and systems, electronic commerce, and application management.
  • Legal, policy, and regulatory topics such as: copyright, content control, content liability, settlement charges, "modem tax," and trademark disputes in the context of internetworking

In addition to feature-length articles, IPJ contains standardization updates, overviews of leading and bleeding-edge technologies, book reviews, announcements, opinion columns, and letters to the Editor.


At this time, Cisco Systems, Inc. has decided not to continue publishing The Internet Protocol Journal (IPJ) effective immediately.

Cisco wishes to thank Ole Jacobsen, the Editor and Publisher of IPJ for his tireless and professional efforts to inform the community of the Internet, its varied protocols, and its impact upon the world through this publication. Cisco also wishes to thank the authors of the published articles, and all those who submitted articles. A special note of thanks goes to the IPJ Editorial Advisory Board and the article reviewers who have helped to maintain the very high standards of journalistic and technical quality of IPJ.

The online version of the Internet Protocol Journal will remain available for reference here, including all back issues in PDF and HTML format as well as the index files. The new IPJ website can be found at:
