Publication number: 20250125990Abstract: The present invention relates to methods and systems for transmitting and receiving data packets between a first network node and a second network node through a bonded connection. At the first network node, a data packet, a session identification of the data packet and a time value of the data packet are encapsulated in an encapsulating packet. The first network node sends the encapsulating packet from the first network node to the second network node through the bonded connection. The second network node then stores the encapsulating packet after receiving it and determines an expiration time of the encapsulating packet. When the expiration time of the encapsulating packet expired, the second network node dequeues the encapsulating packet and forwards the data packet according to destination of the data packet.Type: ApplicationFiled: November 26, 2024Publication date: April 17, 2025Applicant: Pismo Labs Technology LimitedInventors: Patrick Ho Wai SUNG, Kam Chiu NG, Wan Chun LEUNG

Patent number: 12255808Abstract: Described in example embodiments herein are methods and systems for implementing sending packets from a first network node to a second network node. Packets belonging to the same session may be sent through the same or different tunnels. The second network node processes packets belonging to the same session using the same core. In accordance with an example embodiment, the first network node informs the second network code the core to process the packets. Optionally, selection of core at the second network node is assisted by a core identity created by the first network based on the session. The core identity may be stored in the header or payload of the packets. In an example embodiment, the second network determines the core for processing packet belonging to the same session.Type: GrantFiled: June 13, 2022Date of Patent: March 18, 2025Assignee: Pismo Labs Technology LimitedInventors: Patrick Ho Wai Sung, Kam Chiu Ng, Wan Chun Leung

Publication number: 20240401226Abstract: An ingot puller for producing a single crystal semiconductor ingot includes a housing defining a growth chamber, a crucible positioned within the growth chamber, an ingot receiving vessel defining an ingot receiving chamber connected with the growth chamber, and a feed assembly for charging semiconductor material to the crucible. The feed assembly includes a dumper for containing the semiconductor material and moveable in the ingot receiving chamber between a raised position and a lowered position. The dumper includes a bottom and a sidewall releasable from the bottom to allow the semiconductor material to exit the dumper. The feed assembly also includes opening pins selectively extendable into and retractable from the ingot receiving chamber.

Patent number: 11799686Abstract: The present invention discloses methods and systems for sending information packets from a first network node to a second network node. An aggregated tunnel is established between the first network node and the second network node. An information packet is determined whether to be sent according to profile condition(s) of the aggregated tunnel and then according to a selected policy. When a selected policy is selected and the information packet is sent through a tunnel according to the selected policy. When no policy is selected, the information packet is sent through one of a first group of tunnels. When no profile is selected, the information packet is sent through a network interface of the first network node.Type: GrantFiled: November 9, 2020Date of Patent: October 24, 2023Assignee: Pismo Labs Technology LimitedInventors: Patrick Ho Wai Sung, Kam Chiu Ng, Wan Chun Leung, Ho Ming Chan
