Latest Patents

One of his latest patents is titled "Method and system for generating data frames for asynchronous over TCP/IP protocol." This invention describes a method and system for generating an asynchronous data frame. A character received from an asynchronous device is buffered. Each additional character from the asynchronous device is buffered if the additional character is received before the expiration of a predetermined interval measured from a time when the last buffered character was received. The one or more buffered characters are assembled as a data frame after the expiration of the predetermined interval if no additional character is received from the asynchronous device before the expiration of the predetermined interval. An encapsulated TCP packet that includes the data frame is generated for transmission across a TCP/IP network to a remote device.

Another notable patent is "Method and apparatus for defining failover events in a network device." This invention defines a critical interface for a network device such that if the critical interface goes DOWN, the network device will perform a forced failover. IP addresses are assigned to interface groups, and interface groups are assigned to a critical interface. The critical interface will go DOWN if any one of the interface groups goes DOWN. However, the interface groups will not go DOWN unless all members' IP addresses assigned to the interface group go DOWN. By configuring the critical interface in this manner, the network manager has increased flexibility in defining which events should and should not trigger failover of the network device.
