摘要： A technique for adaptively distributing a web server request in a system having a plurality of web servers is disclosed. In one embodiment, the technique is realized by first generating a web server request distribution function for each of the plurality of web servers based upon performance measures of each of the plurality of web servers, wherein each of the plurality of web servers is assigned a respective probability range based upon each respective web server request distribution function. A random probability number is then generated for a web server request. The particular probability range encompassing the random probability number is then determined so as to identify the corresponding web server to which the web server request is to be distributed.

摘要： A method for preventing information losses due to network node failure is disclosed. The method comprises the steps of operatively connecting at least one backup node to a primary node, followed by synchronizing the at least one backup node and the primary node. Next, the method comprises receiving, from a first endpoint, ingress traffic in the primary node and replicating the ingress traffic to the at least one backup node. Next, the method outputs, from the primary mode, primary egress traffic and outputs, from the at least one backup node, backup egress traffic. The method then determines if the primary node has failed. Then, the method transmits, to a second endpoint, the primary egress traffic if it is determined that the primary node has not failed, and transmits, to the second endpoint, the backup egress traffic from a selected one of the at least one backup nodes if it is determined that the primary node has failed.
