Internet Protocol Forum

by Kunjal Trivedi, Cisco Systems and Damien Holloway, Juniper Networks

As transport becomes a commodity, service providers are seeking new revenue sources and new ways to differentiate themselves. Managed security services address a growing market because business customers are struggling to comply with regulatory requirements such as the Payment Card Industry-Data Storage Standards (PCI-DSS), the Sarbanes-Oxley Act, the Gramm-Leach Bliley Act, Health Insurance Portability and Accountability Act (HIPAA), Directive 2002/58/EC, and the Asia-Pacific Economic Cooperation-Organization for Economic Cooperation and Development (APEC-OECD) initiative on regulatory reform. Increasingly, business customers recognize that outsourcing network security is less costly than staffing with highly specialized security personnel who can provide 24-hour incident detection and response. Another incentive for outsourcing is to free existing IT resources to focus on the core business.

In September 2005, The Internet Protocol Journal published an article about the IPv4 address space consumption [1]. At that time, projections done by Geoff Huston and Tony Hain varied widely, because the number of /8 address blocks in use had gone up sharply in early 2005. So what has happened since then, and what can we expect for the not-too-distant future?

IPv4 has proven to be exceedingly popular, so it should be no surprise that the time is rapidly approaching when the last /8 block will be allocated and the Internet Assigned Numbers Authority’s (IANA’s) free pool of address space will be empty. At the time of writing, Geoff Huston of the Asia Pacific Network Information Centre (APNIC) is projecting the IANA free pool will run out in mid-2010. Unfortunately, it is possible that some of these remaining /8s may cause problems for enterprise and Internet Service Provider (ISP) network operators when they are put back into use. These blocks are not the /8s that have been returned to IANA by the original registrants; they are previously unassigned address blocks.

Uncommon Sense: Out of the Box Thinking for An In the Box World, By Peter Cochrane Review by Edward Smith, BT, UKA series of articles published in silicon.com form the basis for this book, which looks at the effect that new technology has on business and its implications for society. In many ways it attacks conventional wisdom and forces a reevaluation of the effect of technology, often exposing flaws in the business logic that lead to many investments and decisions.

The book is aimed at technologists, managers, and professionals who are interested in change and progress, offering them a glimpse of the future. It is easy to read, with liberal use of figures and tables to aid understanding.

The Internet Protocol Journal (IPJ) is published quarterly by Cisco Systems. The journal is not intended to promote any specific products or services, but rather 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. 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.
