Publication number: 20230388372Abstract: A logical grouping of subgroups of server clusters forms a failover super-cluster. A logical grouping of groups of servers provides high availability by, upon failure of an entire group (site), failing over an entire subgroup to a different subgroup. Yet within each subgroup local failovers continue to maintain application high availability during instances in which the site remains operational.Type: ApplicationFiled: July 26, 2023Publication date: November 30, 2023Applicant: DH2i CompanyInventors: Thanh Q.

Patent number: 11677584Abstract: A datagram-oriented UDP protocol is used for communication between tunnel gateways in a wide area network. Lightweight remote client accesses network services using TCP tunneling. Each remote client maintains one or more UDP/IP+DTLS communication channels to a single member of the gateway group. Gateway servers belonging to the gateway group form some interconnection topology linking each gateway server to each other gateway server, whereby each gateway server maintains a communication channel with every other gateway server in the gateway group.Type: GrantFiled: June 17, 2020Date of Patent: June 13, 2023Assignee: DH2I COMPANYInventors: Thanh Q.

Gateway servers belonging to the gateway group form some interconnection topology linking each gateway server to each other gateway server, whereby each gateway server maintains a communication channel with every other gateway server in the gateway group. Through the links between gateway servers, a remote client may access any application provided by any gateway server within the gateway group regardless of which gateway server it is connected to, which serves to cloak its communication patterns.Type: GrantFiled: December 28, 2020Date of Patent: February 7, 2023Assignee: DH2I COMPANYInventors: Thanh Q.

Patent number: 11323288Abstract: Server cluster communication across the public internet using a single secure User Datagram Protocol (UDP) is facilitated by an intermediary registry server. The intermediary registry server enables servers within a cluster to identify and securely communicate with peer servers in the cluster across disparate locations and through firewalls Using an external address registry shared to each member of a server cluster peer group, individual servers can establish a direct secure channel using a single UDP tunnel.Type: GrantFiled: August 6, 2019Date of Patent: May 3, 2022Assignee: DH2I COMPANYInventors: Thanh Q.

Patent number: 11165891Abstract: Redundant transmission control protocol tunneling of the present invention channels client application data through the public Internet via a secure UDP channel. By integrating one or more gateway applications interposed between an endpoint and the public Internet using local loopback addresses, the present invention provides network path failover redundancy.Type: GrantFiled: August 26, 2019Date of Patent: November 2, 2021Assignee: DH2I COMPANYInventors: Thanh Q.

Patent number: 11082254Abstract: Network TCP tunnels are dynamically configured to support intra-application connectivity of a distributed application. Tunnel origins listen on each server's loopback address. This listening configuration permits only applications running on the same server to connect. A tunnel gateway application interfaces with the distributed application on each server and includes a tunnel endpoint manager configured to select one or more TCP ports. These selected ports are each associated with a separate TCP listeners. Once associated, data from the instance of the distributed application resident on each of the plurality of servers in the server cluster is routed through these TCP connections and a UDP datagram-orientated communication channel formed between each peer in the server cluster. Each instance of the distributed application can thereafter access peers in the server cluster through each unique UDP datagram-orientated communication channel.Type: GrantFiled: August 6, 2019Date of Patent: August 3, 2021Assignee: DH2I COMPANYInventors: Thanh Q.
