  • Network address cache apparatus and method
    Patent number: 7552237
    Abstract: Cached information that includes multiple network addresses is delivered in a manner that changes the order of the network addresses each time the cached information is delivered to a client, thereby achieving load balancing in a manner that reduces network traffic and improves system performance. In the preferred embodiments, the user defines a minimum time to live (TTL) and one or more order change criteria. When a query is made to a DNS, the DNS returns an answer that includes a time to live (TTL). This answer may be stored in a cache, and may include multiple network addresses. If the TTL for the answer received from a DNS is less that the minimum TTL, the TTL for the answer is set to the minimum TTL before storing the answer in the cache.
