P K Chidambaran, Thomas A Hoch, John Patrick Jones, Andrew A Long, Prasasth R Palnati, Ronald M Parker, Raymond J Schmidt: Apparatus and method for redundancy of processing modules interfaced to a switching core. Lucent Technologies, Matthew J Hodulik, May 17, 2005: US06894969 (21 worldwide citation)

The present invention is a core interface mechanism that permits 1:N type port protection on the core side of the switch such that core bandwidth is not wasted by the direct connection of service cards to the switching core. In an exemplary embodiment, a core interface module supports up to two acti ...

Prasasth R Palnati: Management of free space in an ATM virtual connection parameter table. Ascend Communications, Weingarten Schurgin Gagnebin & Hayes, May 28, 2002: US06396838 (18 worldwide citation)

Port cards in an ATM switch store parameters for virtual channel connections (VCCs) and virtual path connections (VPCs) in separate areas of a virtual connection parameter table (VCPT), the areas being defined by a VCC pointer and a VPC pointer. Also, a number of “free lists” are used to identify un ...

Deepak Garg, Prasasth R Palnati, Prince Samar: Dynamic modification of route update protocols. Airvana Networks Solutions, Fish & Richardson P C, December 27, 2011: US08085696 (14 worldwide citation)

A radio access network dynamically modifies a route update protocol of an access terminal in an active state that is in communication with the network, such that the access terminal reports a route update message upon satisfaction of a condition. The condition may be related to an inter-revision har ...
