DOMAIN NAME SERVER (DNS) PROTOCOL REQUEST TRACKER

Abstract

Assisting in the alleviation of Domain Name Service (DNS) request saturation by tracking and identifying DNS queries sent from a server to at least one target server and DNS answers sent from the at least one target server to the server in response to the DNS queries. In response to identifying the DNS queries and DNS answers, (i) destination ports are determined for each DNS answer, with each destination port being associated with a network source, (ii) the network source associated with each destination port is identified, and (iii) the number of connections made between each destination port and the at least one target server is determined. Determining the number of connections between each destination port and the at least one target server can be used, along with DNS caches, to consolidate multiple connections between a destination port and the at least one target server into one persistent connection.
