Latest Patents

One of Cheng's latest patents is titled "Preserving Quality of Service Across TRILL Networks." This invention describes systems and techniques for processing and forwarding packets. An ingress switch utilizes a Quality of Service (QoS) mapping mechanism to translate a first set of QoS bits from a customer packet into a second set for use in a Transparent Interconnection of Lots of Links (TRILL) packet. This innovation ensures that the TRILL packet can be processed and forwarded based on the second set of QoS bits, ultimately preserving the original QoS bits when the packet reaches the customer's network.

Another notable patent is the "Method and System for Link Aggregation Across Multiple Switches." This invention provides a switch that includes a forwarding mechanism and a control mechanism. The forwarding mechanism operates based on Ethernet headers, while the control mechanism allows the switch to function alongside a separate physical switch as a single logical entity. This system assigns a virtual switch identifier associated with a link aggregation group, enhancing network efficiency.
