With a total of 3 patents to his name, Venkateswaran's work has had a lasting impact on the efficiency of information transport in communication networks.

Latest Patents

One of his latest patents is a technique for efficiently transporting information through an ATM communications system. In this innovation, all ATM switches in a multicast connection perform virtual path (VP) switching, except for merge points that perform virtual channel (VC) switching to avoid VCI collisions. The merge points are ATM switches that can merge ATM traffic from at least two incoming links into an outgoing link. In a second approach, each merge point in a multicast connection performs VP switching and dynamically dispenses VC switching when a VCI collision is detected. Specifically, to prevent further VCI collisions, incoming ATM cells indicated by an odd VPI value are VC switched by the merge point, while those indicated by an even VPI value are VP switched.

Another significant patent involves a dynamic distributed multicast routing protocol. This innovation enhances the distribution of multicast information in a communications network formed from multiple communications nodes, such as ATM switches. It provides an efficient mechanism for routing a request to join a multicast connection to its originator and efficiently connects the requester to the multicast connection.
