  • Method and computer readable medium for DNS dynamic update to minimize client-server and incremental zone transfer traffic
    Patent number: 6411966
    Abstract: The invention reduces network traffic between client computers and DNS server computers by allowing client computers to send information to DNS server computers that have implemented protocols RFC 2136 and RFC 1995. Network traffic is-minimized in DNS database updates between client computers and server computers by sending a small amount of data. The invention also minimizes the replication of DNS updates between DNS server computers in the face of protocol RFC1995 and defeats Windows Internet Naming System (WINS) referral by its ability to update DNS server computers that emulate WINS server computers and have WINS referral capabilities. Thus, when a client computer's data changes, updates to the DNS database are performed with the minimum number of activities so that the database reaches a desired state, where the minimum amount of data will replicate by sending the minimum content of data replication from one DNS server computer to another.

  • Method and computer readable medium for discovering master DNS server computers for a given domain name in multiple master and multiple namespace configurations
    Patent number: 6381627
    Abstract: The invention detects multiple master DNS server computers and handles multiple namespaces. In traditional DNS, each zone or domain has a primary or master server computer as well as one or more slave server computers. Both the master server computer and the slave server computers have complete information regarding a particular zone. The master server computer is distinct in that it receives changes made by a client. The slave server computers periodically update their own information from the master server computer. In multiple master DNS, each server computer is essentially a primary server computer in that any server computer may accept updates from a client. This information is then distributed to the other multiple master server computers.
