Latest Patents
One of his latest patents is for a global server load balancing (GSLB) switch. This invention serves as a proxy to an authoritative DNS and communicates with numerous site switches connected to host servers that serve specific applications. The GSLB switch receives operational information from site switches regarding host servers in its vicinity. When a client program requests a resolution of a host name, the GSLB switch returns one or more ordered IP addresses based on metrics that include the information collected from the site switches. In this instance, the GSLB switch prioritizes the address deemed 'best' at the top of the list.
Another notable patent is for connection rate limiting for server load balancing and transparent cache switching. This invention allows each service in a computer network to have a connection rate limit. The number of new connections per time period can be limited using a series of rules. In a specific embodiment, a counter is increased each time a server is selected to handle a connection request. This method tracks incoming connections without needing to examine the source of connection-request packets, thus saving significant time in processing requests.
