I. Keene, B. Hafner Research Note 23 December 2002 Commentary The Telecommunications and Networking Hype Cycle New networking technologies and services continue to stream into the telecommunications marketplace. The hype cycle illustrates forthcoming technologies and services and how long it will be before they provide real value. The telecommunications and networking hype cycle in (Figure 1) is a consolidation of the primary technologies and services that are aggressively marketed (that is, "hyped") to service providers and enterprises. Gartner has attempted to put context and timeframes around each, allowing individuals to determine the amount of effort and time they should spend to monitor, evaluate, or implement the technology or service.

The Five Stages of the Hype Cycle Technology trigger: An event that generates significant press and industry interest, such as a breakthrough, invention, discovery, public demonstration or product launch. Peak of inflated expectations: During this phase of over enthusiasm and unrealistic projections, a flurry of well-publicized activity by technology leaders results in some successes, but more failures, as the technology is pushed to its limits. The enterprises that make money during this phase are generally conference organizers, magazine publishers and consultants. Trough of disillusionment: The technology does not live up to inflated expectations, and, as a result, it rapidly becomes unfashionable, and the press abandons the technology or touts its failure to meet expectations. Slope of enlightenment: Focused experimentation and solid hard work by an increasingly diverse range of organizations leads to a true understanding of the technology's applicability, risks and benefits. Commercial off-the-shelf methodologies and tools become available to ease the development process and application integration. Plateau of productivity: The real-world benefits of the technology are demonstrated and accepted. Tools and methodologies are increasingly stable as they enter their second and third generations. The final height of the plateau varies according to whether the technology is broadly applicable or benefits only niche markets. Networking Technologies Asymmetric digital subscriber line (ADSL) deployment continues to grow, connecting millions of small offices, remote workers and consumers to broadband services. Many network service providers have multiprotocol label switching (MPLS) services, and enterprises are starting to move from frame relay to MPLS. Voice over IP (VoIP) the transport of packetized voice over an IP network has been successfully used in core networks for several years and is integrated into routers and private branch exchanges. IP telephony as a user application has yet to climb the slope of enlightenment. Application service provider (ASP) services remain in the trough of disillusionment, but this will change as a result of the expanding use of broadband services provided by Ethernet metropolitan area networks (MANs) during 2004 to 2007. Next-generation carrier infrastructure technologies such as softswitches, optical switching and general MPLS (GMPLS) are at least two years away from implementation, as carriers move the focus of their investments. version 6 of IP (IPv6) has been on the horizon for years but the ubiquity of IPv4 has made many nervous of the move. We believe that service providers will have a need for IPv6, but enterprises will not have a need for at least the next five years. Content delivery networks (CDNs) fulfill enterprises' drive to provide increasing amounts of content. However, enterprises are only starting to understand what they need from, and how to implement, CDNs. Wireless Technologies Wireless LAN (WiFi) moved through the hype cycle quickly during 2001 and 2002. Standard 802.11b is established in many enterprises, while 802.11a and 802.11g products are forecast to see high-volume adoption from the second half of 2003 onward. WiFi public "hot spots" are for early adopters, but it will reach the plateau of productivity within two to five years. Third-generation (3G) cellular networks are in 23 December 2002 3
the trough of disillusionment; cellular operators first need to prove their ability to run profitable general packet radio service (GPRS) data services. Although there are now a large number of Bluetooth-enabled devices on the market (particularly in cellular phones), problems remain with inconsistent interoperability of products, limiting the use of Bluetooth as a personal-area network technology. Location-aware services will continue to improve dramatically during 2003 and 2004. By 2007, high-accuracy services will become mainstream. Security and Storage Technologies The emergence of new security technologies continues. While IP security (IPSec) is being adopted by more enterprises, denial of service (DoS) will be a technology only for the early adopters for the next one to two years. Intrusion prevention and "in the cloud" (in the WAN) security services (contained within carrier networks) are two to five years away from mainstream adoption. While networked attached storage (NAS) is accepted by enterprises, fiber channel storage area networks (FC SANs) are still climbing the slope of enlightenment. The alternative IP small computer system interface (iscsi) SAN technology, is very much at the early adopter stage. Market Downturn Affects the Hype Cycle The downturn in start-up activity since mid-2000, has resulted in fewer technologies to the left of the "peak of inflated expectations" than in the previous five years. Although opportunities to invest in both start-ups and small vendors still abound, in general, investors are skeptical. Those that are considering investment are researching their candidates far more carefully and tend to look toward building strong companies as opposed to strong stocks. Seed funding in particular has dropped dramatically. This would be a good opportunity for the large and established telecommunications and networking vendors to have a more significant role in innovation. Unfortunately, most of these companies are scaling back and focusing on immediate issues and the development of existing products. This situation is expected to continue until the end of 2004, by which time the telecommunications and networking market will need new technologies, but organizations with those new technologies and funding abilities will be rare and sought after. This will generate a new cycle of investment and a potential change in the vendor landscape. Moving Through the Cycle Technologies move through the hype cycle at different speeds and these speeds are rarely constant. The trough of disillusionment can be a particular bottleneck. For technologies to reach the plateau of productivity within the next five years, they must either leverage previous investments or need a relatively low-level of investment for implementation. The technologies that move through the hype cycle at the fastest rate will be those that either enable new revenue streams, decrease operating expenses or increase productivity.
