  • Supporting DNS security in a multi-master environment
    Patent number: 8681995
    Abstract: Multiple peer domain name system (DNS) servers are included in a multi-master DNS environment. One of the multiple peer DNS servers is a key master peer DNS server that generates one or more keys for a DNS zone serviced by the multiple peer DNS servers. The key master peer DNS server can also generate a signing key descriptor that identifies the set of one or more keys for the DNS zone, and communicate the signing key descriptor to the other ones of the multiple peer DNS servers.
    Type: Grant

    Date of Patent: March 25, 2014
    Assignee: Microsoft Corporation

  • Method and system for detecting a dead server
    Patent number: 7395328
    Abstract: Method and system for detecting a dead server in a multi-server environment. A virtual ring structure is used in which each server in a server pool is only required to monitor the status of two other servers in the server pool. Thus, a server need only transmit ping signals to two other servers (its buddies) in the server pool at any given time. Because each server maintains the status of only two other servers at any given time, the size of the server pool is not limited by the ability of each server to send and process ping signals. The two servers which are monitored by any given server in the server pool are referred to as the “buddy A” server and the “buddy B” server. When the monitoring server determines that one of its buddy servers is down, the monitoring server reports the status of the down server to a SQL server that maintains a server table. The server table maintains a list of each “live” server and the buddy servers assigned to that server. Down servers are removed from the server table.
