Publication number: 20210235521Abstract: The present disclosure provides systems and methods which increase the throughput of a TCP-based communication between a first network node and a second network node. First, the first network node sent a first plurality of TCP segments to the second network node. Second, when the second network node receives a second plurality of TCP segments, which is all or part of the first plurality of the TCP segments, the second network node responds by sending one or more TCP acknowledgements to the first network node with the last sequence number of a last segment among all TCP segment within the second plurality of TCP segments. The present disclosure are able to increase the throughput of a TCP connection while decreasing its reliability.Type: ApplicationFiled: March 25, 2021Publication date: July 29, 2021Applicant: 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

Publication number: 20210176211Abstract: A method and a system of restricting data packet transmission of an apparatus at a network node. The network node, during a first time period, updates a whitelist and does not restrict data packet transmission according to the whitelist. After the first time period, the network node determines corresponding destination address of each of the data packets and allows the data packets to be sent to the corresponding destination address if a criteria is satisfactory. The network node does not allow the data packets to be sent to the corresponding destination address if the criteria is not satisfactory. The whitelist is comprised of at least one destination address. The criteria is based on the at least one destination address. The whitelist list is stored in non-transitory computer readable storage medium in the network node.Type: ApplicationFiled: February 22, 2021Publication date: June 10, 2021Applicant: Pismo Labs Technology LimitedInventors: Wan Chun Leung, Patrick Ho Wai Sung, Kit Wai Chau

Patent number: 10965789Abstract: A method and a system for updating a first whitelist at a network node. The network node receives data packets from an Internet of Things (IoT) device and determines a predetermined identifier for the IoT device. The network node then determines whether the predetermined identifier is in the first whitelist. When the predetermined identifier is not in the first whitelist, the network node starts a first time period. When the predetermined identified is on the first whitelist, the network node determines whether the data packets are received within the first time period. When the data packets are received within the first time period, the network node identifies destination addresses of the data packets and updates the first whitelist based on the destination addresses and the predetermined identifier. The updated first whitelist is stored in non-transitory computer readable storage medium in the network node.Type: GrantFiled: March 23, 2017Date of Patent: March 30, 2021Assignee: Pismo Labs Technology LimitedInventors: Wan Chun Leung, Kit Wai Chau, Patrick Ho Wai Sung

Publication number: 20200322257Abstract: 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: ApplicationFiled: May 24, 2020Publication date: October 8, 2020Applicant: Pismo Labs Technology LimitedInventors: Patrick Ho Wai SUNG, Kam Chiu NG, Wan Chun LEUNG

Publication number: 20200322096Abstract: The present invention discloses 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: ApplicationFiled: June 22, 2020Publication date: October 8, 2020Applicant: Pismo Labs Technology LimitedInventors: Patrick Ho Wai Sung, Kam Chiu NG, Ho Ming CHAN
