Latest Patents

One of Dean Cheng's latest patents is titled "Interior Gateway Protocol Flood Minimization." This patent discloses a mechanism for implementing link state flooding reduction in an IGP network. The mechanism involves receiving data that indicates the connectivity of multiple nodes within the network. A flooding topology is constructed based on this connectivity, which includes selecting a root node and building a tree of links that connect the root node to the other nodes. This flooding topology is then stored in memory, allowing for efficient flooding of link state messages over the established topology.

Another notable patent is "System and Method for Handling IGP Flooding Topology Inconsistency." This patent describes a network node that manages IGP flooding topology inconsistencies by obtaining a new flooding topology and setting a flag in a data packet to indicate the status of links between nodes. The node transmits this data packet to another node, which then checks for inconsistencies in the flooding topology. If discrepancies are found, the node sets a field in a link state packet to indicate the inconsistency, ensuring that the network maintains accurate and reliable communication.
