LocalDirector is a hardware and software solution offered by Cisco Systems; it has a secure, real-time, embedded operating system that intelligently load balances TCP/IP traffic across multiple servers. Delivering very fast performance by distributing client requests across a cluster of low-cost servers, LocalDirector dramatically reduces the cost of providing large-scale Internet services, and speeds user access to those applications.

The load-balancing options of Local Director provides a flexible and adaptable method for directing TCP/IP traffic. You can configure LocalDirector to maximize the number of TCP/IP connections a server farm can manage. TCP/IP traffic is directed to dif ferent servers based on service, speed, or quantity of connections.

LocalDirector is a high-performance Internet appliance with over 45-Mbps throughput. It supports a combined total of 8000 virtual IP addresses and real servers. The real servers can be a collection of heterogeneous hardware platforms and operating syst ems. Quick setup with no network address changes reduces system administration time.

Ideal for mission-critical applications, LocalDirector provides the capability to build a highly redundant and fault-tolerant server system. Servers are automatically and transparently placed in and out of service, providing fault tolerance for servers . LocalDirector itself is equipped with an optional hot-standby failover mechanism, building increased redundancy for the server system.
