19 Jun 1997TL;DR: In this article, a message dispatch system is provided for a multi-computer server having a number of server computers connected via respective server network links, which is connectable to an external telecommunications network.
Abstract: A message dispatch system is provided for a multi-computer server having a number of server computers connected via respective server network links. The message dispatch system, which is connectable to an external telecommunications network, includes a message dispatcher configured to receive external client requests for the multi-computer server from the external telecommunications network and to dispatch the client requests to selected server computers via the server network links. The message dispatcher is configured to determine a server to which an external client request is to be dispatched in response to parameters representative of message traffic volume on the server network links. Load balancing is performed based on parameters representative of the server network link loading, rather than, or possibly in addition to measurements on processor loading. Suitable network loading parameters can be derived by monitoring packets passing from and/or to the individual server computers. The monitoring can be performed in the dispatcher, or in a switch or a separate traffic monitor between the dispatcher and the server network links, for example.

TL;DR: In this article, various techniques for allowing non-secured clients to access secured data of an enterprise from a public network without compromising security integrity of the enterprise are disclosed, where the interface server is analogously placed in a "Demilitarized Zone" and referred to as a DMZ server.
Abstract: Various techniques for allowing non-secured clients to access secured data of an enterprise from a public network without compromising security integrity of the enterprise are disclosed. According to one embodiment, a server, referred to as an interface server, is designated to interface with non-secured clients and coupled between a private network and a public network. The server can be one of local servers in a security system employed in an enterprise. In certain respect, the interface server is analogously placed in a “Demilitarized Zone”, hence also referred to as a DMZ server. Through the DMZ server, some of the secured data in the enterprise can be accessed by the non-secured clients without compromising the security integrity of the enterprise.

15 Nov 2005TL;DR: In this paper, the authors describe a method and system for seamless roaming of a mobile node during a VPN session, where the mobile node is established and synchronized with at least one fail-over VPN server in the network.
Abstract: Described are a method and system for seamless roaming of a mobile node during a VPN session. A VPN session between the mobile node and a current VPN server in a network is established and synchronized with at least one fail-over VPN server in the network. An address change message is sent to the current VPN server and the fail-over VPN servers upon roaming of the mobile node. A fail-over VPN server responds with a reply message and is registered as a current VPN server for continuation of the VPN session. To load balance, a load query message is sent to the current VPN server and the fail-over VPN servers. Reply messages include server performance characteristics of the VPN servers. The VPN session can be transferred from the current VPN server to a fail-over VPN server in response to the server performance characteristics.
