I uncovered a lot of latent hostility last week, after writing about research on the Internet transmission delays known as "latency." The research by Sanford C. Bernstein analyst Zhiping Zhao argues that incipient rises in Internet latency mean that network operators will have to start buying components from firms such as JDS Uniphase and Agere Systems. As JDS Uniphase shares jumped from 2.90 to more than 4 last week, and Agere shares rose from 1.84 to 2.70, rival analysts called latency a fallacy and warned investors about the stocks. Let me add my warning that even if Zhao's right on the money, four bucks is a lot to pay today for the 26 cents Zhao says JDS will earn in the year ending June 2005. Zhao confessed that she couldn't tell whether latency was caused by congestion in the optical layer of networks supplied by JDS, or in the electrical switches known as routers. George C. Notter, telecommunications-equipment analyst at Deutsche Bank's San Francisco office, says the congestion is in the routers. Any spending to reduce latency, Notter argues, will first benefit router makers like Cisco Systems and Juniper Networks and, much later, the optical firms like Ciena, Lucent Technologies and Nortel Networks that are JDS's customers. Meanwhile, carriers have equipment from underused links that they can redeploy to links where traffic's growing. Capital budgets continue to decline at telecom carriers, says Morgan Stanley networking analyst David A. Jackson. "In the post-bubble world," Jackson said in a report Thursday, "corporate investment is no longer driven by traffic growth, page views, minutes of use or number of subscribers. We believe spending is driven by one metric only: expected return on investment." Like Bernstein's Zhao, Raymond James analyst Todd Koffman has been studying network links. For a year, the St. Petersburg, Fla., analyst has measured traffic on a half-dozen network links of Metromedia Fiber. That network's AboveNet unit discloses network data at the Website west-boot.mfnx.net/traffic. Koffman reports that peak utilization on those pipes is down to mid-20% levels -- around half the level of a couple of years ago. "It remains our view that excess capacity in the network remains," Koffman wrote Thursday, "and a large-scale network upgrade is now at least 4.3 years away." Bernstein's Zhao says she welcomes the debate, and she's sticking to her guns. Latency delays will anger business customers, she argues. AT&T business customers pay extra for quality-of-service guarantees that include low latency levels. And if AT&T suddenly begins ignoring customer complaints -- as some fear it will, now that WorldCom is out of the picture -- it won't be able to ignore latency problems because delays would mess up the network's operation. Even carriers in bankruptcy, such as Europe's KPNQwest, will spend money to prevent network deterioration. The Bernstein analyst concedes that demand will remain a long way off for purely optical components that have long shelf lives and high prices. Such products are made by Corning, and to a lesser extent, by JDS Uniphase. Continued advances in electronics, however, will sustain demand for the products of JDS and Agere that are known as transceivers. "This idea of looking at latency is something new," she admits. "Let's all see if it works."
