zdnet.com Rescuing lost e-dollars Developers ready tools that speed sites, hold customers By Paula Musich, Scot Petersen and John Rendleman October 25, 1999 9:00 AM ET As e-commerce sales soar, Web performance is becoming a critical issue that has a direct impact on a company's online bottom line. For IT managers charged with not only keeping Web sites operating but operating fast, ensuring availability is no longer enough. "Performance is a growing concern," said Doug Williams, senior vice president of technology at Family Education Co., in Boston. "If I have users saying the system is down, that keeps me from sleeping at night. Going forward, the next thing that'll keep me up at night is a slow system." To address this issue, vendors including Cisco Systems Inc., Response Networks Inc., Quantum Bridge Technologies Inc. and Storm LLC are readying products that attack different pieces of the Web site performance conundrum. Cisco this week will address the load balancing piece of the puzzle with new MNLB (Multinode Load Balancing) technology that integrates some load balancing functions into Cisco switches and routers. The technology separates load balancing into two pieces: One is implemented as a software option for Cisco's existing Local Director load balancing device; the other is a feature of Version 12.05T of Cisco's IOS control software for the San Jose, Calif., company's routers and switches. With Local Director, the software decides which server in a data center will satisfy a particular user request. The IOS software then shuttles packets between the designated server and the client requesting the data or executing the transactions. MNLB also adds more mechanisms for making decisions about which servers will satisfy certain requests.
