Patent number: 11943060Abstract: Methods and systems for managing an error correction mode at a first communications router. The first communication router transmits data packets to a second communications router and stores the first data packet in a local storage medium. When a delay inquiry message is received from the second communications router, the first communications router activates the error correction mode. When the error correction mode is activated, the first data packet is retransmitted to the second communications router and an error correction packet corresponding to the first data packet is also transmitted. When a back-to-normal message is received from the second communications router, the first communications router deactivates the error correction mode. The back-to-normal message indicates that the first communications router no longer needs to be in error correction mode.Type: GrantFiled: June 12, 2023Date of Patent: March 26, 2024Assignee: Pismo Labs Technology LimitedInventors: Patrick Ho Wai Sung, Kam Chiu Ng, Ho Ming Chan

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

Patent number: 11582814Abstract: A method and system for a first node to transmit packets to a second none, comprising receiving a packet from a local area network (LAN) interface, inspecting the packet; determining whether the packet satisfies at least one packet condition; transmitting the packet through a predefined tunnel if the packet satisfies the at least one packet condition; transmitting the packet through a second tunnel if the packet does not satisfy the at least one packet condition. The predefined tunnel is a first tunnel and is established before the packet is received by the first node. The second tunnel belongs to a first tunnel group or a second tunnel group. The first tunnel, the second tunnel and other tunnels may together form an aggregated connection. Further, the use of predefined tunnel may be based on whether the packets satisfy a session condition.Type: GrantFiled: July 20, 2020Date of Patent: February 14, 2023Assignee: Pismo Labs Technology LimitedInventors: Patrick Ho Wai Sung, Kit Wai Chau, Kam Chiu Ng, Wan Chun Leung, Ying Kwan, Martin Langmaid

Publication number: 20220263681Abstract: 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: February 7, 2022Publication date: August 18, 2022Applicant: Pismo Labs Technology LimitedInventors: Patrick Ho Wai SUNG, Kam Chiu NG, Wan Chun LEUNG

Patent number: 11076000Abstract: The present invention discloses methods and systems for transmitting a received packet at a first network node through an aggregated connection. The first network node determines session information of the received packet and determines whether a new tunnel needs to be selected for transmitting the received packet. When a new tunnel needs to be selected, a hash result is determined. The hash result is substantially based on the session information and the number of available tunnels. A first tunnel is determined for transmitting the received packet according to the hash result. The session information and tunnel ID of the first tunnel is then stored in a first database. The received packet is transmitted through the first tunnel. When a new tunnel need not be selected, a lookup is performed to determine a tunnel ID substantially based on the session information. The received packet is transmitted through the determined tunnel.Type: GrantFiled: November 4, 2019Date of Patent: July 27, 2021Assignee: Pismo Labs Technology LimitedInventors: Kam Chiu Ng, Patrick Ho Wai Sung, Ying Kwan, Wan Chun Leung
