Understanding VPN Load Balancing
VPN load balancing is a specially designed configuration for effective VPN load balancing on a given Content Switching Module or CSM. VPN load balancing is basically a mechanism that very sophisticatedly distributes the various VPN sessions among a set of dedicated VPN concentrators or VPN head-end components.
VPN load balancing is adopted and implemented for a number of industry specific applications. The need to deploy the technology of VPN load balancing includes the need to overcome limitations on the vital performance and scalability within operations on VPN devices. These include the devices like 'packets per second' and 'connections per second', to effectively remove any single point of failure.
Within the system:
Within the system is the Novell Access Manager 3. This is a dedicated access control solution that is comprehensive and offers users seamless and single sign-on access across various defined technical and organizational boundaries. The access provided is based upon the Identity Federation standards stressed upon by the industry. VPN load balancing is a technology that combines advanced wireless capabilities like the multi-factor authentication and user specific data encryption, the single sign on facility that is clientless and SSL VPN that provides secured access from any location. These features are offered in addition to the simplified deployment and administration, which are in a way the trademarks of the technology. VPN basics: VPN load balancing technology is basically designed and configured to provide the users with dedicated and secured access to non-HTTP based applications, within the corporate network. The technology is promoted as 'combined with the quality and sturdy identity services of the Access Manager'. This combination has resulted in the much needed authentication of the technology deployed and secured access to all the resources at hand. The industry dedicated VPN load balancing technology comprises of two distinct components that are designed to handle the specific user sessions, especially the Tomcat servlet and the in-built connection manager. The former feature receives the specific session request from the proxy and validates the requested attributes. The technology then 'informs' or wires the specifications to the dedicated connection manager and this results in the timely delivery of the SSL VPN client component to the end user's computing machine. VPN configuration:
The VPN load balancing technology can also be configured for effective load balancing among more than one SSL VPN connection managers. This is achieved with the use of the Session Persistence feature within the Access Gateway. The prerequisites specified for effective deployment of the technology includes (1) Access Gateway, either Linux or NetWare (2) Identity Server (3) SSL VPN Servlets (4) SSL VPN Server, including the dedicated connection manager, SOCKS Server and the special Stunnel Server. The VPN load balancing technology has enabled many end users to successfully apply the enhanced access to a myriad of business operations.
