Patent number: 10778814Abstract: A system and method for classifying packets according to packet header field values. Each of a set of subkey tables is searched for a respective packet header field value; each such search results in a value for a subkey. The subkeys are combined to form a decision key. A decision table is then searched for the decision key. The search of the decision table results in an action code and a reason code, one or both of which may be used to determine how to further process the packet.Type: GrantFiled: January 24, 2018Date of Patent: September 15, 2020Assignee: Rockley Photonics LimitedInventors: Chiang Yeh, German Rodriguez Herrera, Bhaskar Chowdhuri

Patent number: 10678599Abstract: A system and method for selecting a resource from among a plurality of resources. A total range of numbers is divided into a plurality of sub-ranges, each associated with a respective one of the resources. An indexing number, e.g., a random number, is generated and, when it falls within the total range of numbers, the resource associated with the sub-range into which the indexing number falls is selected. When the indexing number falls outside of the total range, a resource associated with the difference between the indexing number and the greatest number in the total range is selected.Type: GrantFiled: August 31, 2017Date of Patent: June 9, 2020Assignee: Rockley Photonics LimitedInventors: Bhaskar Chowdhuri, Chiang Yeh, Cyriel Johan Agnes Minkenberg, Guy Regev

Patent number: 10205664Abstract: A system and method for routing. A packet includes a stack of one or more headers, such as a stack of Multiprotocol Label Switching headers, that determines the path that the packet will take, through a sequence of switches, from its source to its destination. Each header in the stack contains an output port identifier that identifies an output port of a corresponding switch in the path. Each switch, upon receiving the packet, removes the first header to form a shortened packet, and routes the shortened packet to the output port identified by the output port identifier.Type: GrantFiled: September 28, 2016Date of Patent: February 12, 2019Assignee: Rockley Photonics LimitedInventors: Nathan Farrington, Chiang Yeh, Bhaskar Chowdhuri

Patent number: 9942027Abstract: A system and method for measuring propagation delays and other delays in an optical switching system. A transmitter is connected, through a circuit switch, to a receiver. To measure the propagation delay between the transmitter and the receiver, the transmitter sends one or more time-tagged ranging messages and the receiver calculates a propagation delay from the difference between the time of receipt and the time of transmission. In another embodiment, a time delay between message transmission and transition of a CDR of the receiver to a fast acquisition mode is adjusted, by trial and error, to find a range of such time delays for which transmission is successful. A time delay between the transmitter and the switch is measured by establishing or breaking the connection and determining, for various tentative time delay values, whether transmission succeeds.Type: GrantFiled: March 22, 2017Date of Patent: April 10, 2018Assignee: Rockley Photonics LimitedInventors: Guy Regev, Daniel Brunina, Nathan Farrington, Thomas Pierre Schrans, Chiang Yeh

Publication number: 20160088001Abstract: A system for collaborative deep packet inspection in a network uses a coarse grain mechanism to perform deep packet inspection on sample packets sampled from a plurality of traffic flows received at a network device using a plurality of signatures and develop a profile of the network and a fine grain mechanism to perform real-time inspection of a traffic flow against a small set of the signatures that is updated based on the profile. The fine grain mechanism further enables at least one policy action to be applied to a traffic flow when the traffic flow matches one of the signatures in the set of signatures.Type: ApplicationFiled: September 22, 2014Publication date: March 24, 2016Applicant: ALCATEL-LUCENT USA INC.Inventors: Chiang Yeh, Jeremy W.

Patent number: 9036647Abstract: A method of securely routing data traffic between communication networks. In an integrated security device, a host router supports a virtual router that peers with VRF (virtual routing and forwarding) instances associated with participating networks on the host router. Each VRF instance preferably runs its own dynamic routing protocol and determines when received data traffic may be directly forwarded from one network to another and when it must be forwarded to an OE (offload engine) for enforcement of security policies or NAT (network address translation) processing.Type: GrantFiled: December 27, 2012Date of Patent: May 19, 2015Assignee: Alcatel LucentInventors: Chiang Yeh, Lawrence Helmerich, Sindhu K.

Publication number: 20120080006Abstract: A rotary modulation engine enabling modulation of rotary pistons' rotational speeds is introduced. The rotary modulation engine utilizes four elliptical gears to drive two rotors that overlap each other with rotary pistons thereon alternating one another and rotating in the same direction. The elliptical gears also modulate the relative rotational speeds of these rotary pistons to thereby complete compression, power, exhaust and intake strokes four times in one revolution of a power output shaft of the engine. The rotary modulation engine with the above arrangements has smaller volume and improved efficiency as compared to the conventional four-stroke engine that requires two revolutions of the engine's crankshaft to complete four strokes. The rotary modulation engine can be applied to cars, ships, power generators and the like, and has reduced number of parts, volume and manufacturing cost while provides effectively upgraded operation efficiency.Type: ApplicationFiled: September 22, 2011Publication date: April 5, 2012Inventor: Chun-Chiang Yeh
