Abstract: The present solution allows users, such as administrators to configure slow start parameters for new services. These slow start parameters specify a rate at which requests should be given to a newly added or up service. The users can also chose to automatically increase the load in multiples of the chosen rate by specifying an increment interval. The services are given the configured rate for the interval, and once the interval is reached, the next multiple of the rate of requests is given. The increase of rate of requests is done automatically until an existing service request rate is reached. At that point in time this functionality is disabled and the existing and new services are treated the same.

Abstract: The present invention provides a system and a method for global server load balancing of a plurality of sites based on a number of Secure Socket Layer Virtual Private Network (SSL VPN) users. The SSL VPN users may access servers at each of the plurality of sites. A global server load balancing virtual server (GSLB) may receive a request to access a server. The GSLB virtual server may load balance a plurality of sites wherein each of the plurality of sites may further comprising a load balancing virtual server load balancing users accessing the server accessing servers via an SSL VPN session. GSLB may receive from a first load balancing virtual server at a first site, a first number of current SSL VPN users accessing servers from the first site via SSL VPN sessions. The GSLB may also receive from a second load balancing virtual server at a second site, a second number of current SSL VPN users of the users accessing servers from the second site via SSL VPN sessions. GSLB may determine to forward the request to one of the first load balancing virtual server of the first site or the second load balancing virtual server of the second site by load balancing SSL VPN users across the plurality of sites based on the first number of current SSL VPN users and the second number of current SSL VPN users.

Abstract translation: 本发明提供了一种基于多个安全套接层虚拟专用网（SSL VPN）用户的多个站点的全局服务器负载平衡的系统和方法。 SSL VPN用户可以访问多个站点中的每个站点上的服务器。 全局服务器负载平衡虚拟服务器（GSLB）可能会收到访问服务器的请求。 GSLB虚拟服务器可以负载平衡多个站点，其中多个站点中的每个站点还可以包括负载平衡虚拟服务器负载平衡通过SSL VPN会话访问服务器访问服务器的用户的负载。 GSLB可以从第一站点的第一个负载平衡虚拟服务器接收，第一个当前SSL VPN用户通过SSL VPN会话从第一个站点访问服务器。 GSLB还可以从第二站点的第二负载平衡虚拟服务器接收第二数量的用户通过SSL VPN会话从第二站点访问服务器的当前SSL VPN用户。 GSLB可以基于当前SSL的第一数量来负责平衡多个站点中的SSL VPN用户，来将请求转发到第一站点的第一负载平衡虚拟服务器或第二站点的第二负载平衡虚拟服务器之一 VPN用户和第二个当前SSL VPN用户数。
