Cisco Systems LocalDirector is a high-availability, scalable load balancing solution for TCP/IP and User Datagram Protocol (UDP) traffic across multiple servers and mainframe computer platforms. By providing a unified virtual image to service requestors, LocalDirector enables continuous access to multiple redundant servers for Internet-based e-commerce applications.A sophisticated server connection management system, LocalDirector enables administrators to direct TCP traffic to different servers based on service requested, distribution method, and server availability. All FTP requests can be sent to one cluster of servers while web requests are forwarded to another cluster of servers. LocalDirectors Session Distribution Algorithm (SDA) enables proportionate forwarding of traffic based on weights and maximum number of open connections, ensuring that servers do not fail from traffic overload. LocalDirctor can also probe server applications to determine real-time availability.LocalDirector 430 includes 384 MB of RAM, 2 MB of Flash memory, one 4-port 10/100 Ethernet interface card, optional FDDI, 19-in. rack-mount enclosure, DB-9 EIA/TIA-323 console interface port and 3.5-in. diskette drive.
