Introduction

Antoni Bronislaw Przygienda is a notable inventor based in Sunnyvale, CA, with a remarkable portfolio of 15 patents. His work primarily focuses on advancements in network security and topology, contributing significantly to the field of telecommunications.

Latest Patents

One of his latest patents is titled "Secure network topology." This invention describes a secure IGP topology or other link state topology that can be implemented by a network security unit operating in a centralized environment on servers separate from the network associated with the IGP topology. The network security unit acquires topology information, participates in IGP, or utilizes border gateway protocol with link state (BGP-LS). It detects potential network problems, including indicators of possible network attacks. Upon detection, the unit identifies the compromised node and can report it for manual or automated intervention. Additionally, it can isolate the compromised node by shutting down links connected to it. Another significant patent is "Defining non-forwarding adjacencies in bipartite networks, such as Clos networks, having a level 2 backbone and level 1 nodes." This invention addresses challenges in providing a large Clos network with at least one top of fabric (ToF) node, multiple internal nodes, and several leaf nodes. It proposes solutions such as providing L2 tunnels between leaf nodes and ToF nodes to ensure a non-partitioned IGP L2 backbone while identifying these tunnels as non-forwarding adjacencies in the link state topology information.
