Embodiment Construction

[0016] Figure 1 schematically shows a system environment 10 of the present invention, in which traffic through an Internet server farm 20 can be regulated by a load regulator 12, known as a Web Load Regulator or WWR. In FIG. 1 , incoming traffic (web load) 14 representing IP packets of all client applications (including existing TCP connections and TCP connection requests) enters WWR 12 . The WWR 12 regulates the flow of TCP connection request packets, while transparently passing (admitting) other IP packets (eg, packets for existing TCP connections and packets for non-TCP connections). The admitted traffic (which also includes admitted TCP connection request packets (in the manner described below)) is sent to the load balancer 18 via a high-speed LAN (HS-LAN) 16 . Any rejected TCP connection request packets are processed by the WWR wizard 34, which sends the rejected packets to the outbound link 22. Outgoing link 22 may also be via HS-LAN 16 or other high speed LAN. The bal...

Abstract

A system and method for controlling the rate at which a set of servers accept application load (eg, TCP connection requests). It operates in an environment where each customer has a load-based SLA for each application type that the provider resides on and that the customer uses. The system and method can support (min, max) TCP connection requests to multiple clients and applications. By using a load conditioner to guarantee, control, and deliver load SLAs based on TCP connections for clients whose applications reside on server farms, the load conditioner operates as follows: only condition new TCP connection request packets, while transparently Pass received existing TCP connection packets and other request packets. The regulator also operates by regulating the flow of incoming TCP connection requests applied to each client business activity by applying an admission rate to requests and by dropping (or rejecting) requests to ensure the promised service level to client applications, to ensure that previously The level of service promised to each customer.

Description

technical field [0001] The present invention relates generally to the World Wide Web, and more particularly to the World Wide Internet, and various owned Internet World Wide Web (WWW) sites residing on service providers using a set of servers that seek to satisfy established service level. Background technique [0002] The Internet is the largest network in the world, and it has become indispensable to academic institutions and many small, medium and large businesses, as well as individual users. Many enterprises have begun to outsource their application (business and business) processing to service providers, rather than running and maintaining application software on their own servers. These service providers are called Application Service Providers (Application Service Providers, ASP). Each ASP installs a set of servers (called a server farm) that can be used to run many different business applications for various clients. These customers (ie, "cu...
