Abstract: 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.

Abstract: 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. 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.

Abstract: 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.

Abstract: Statically configured secure tunnels forward application-level Transmission Control Protocol (“TCP”) application data between servers using a User Datagram Protocol (“UDP”) channel. Applications operating on a server cluster can communicate with other applications on another server in the cluster over the public Internet using secure TCP connection forwarding through a single UDP datagram-oriented communication channel.

Abstract: A system for stateful containers in a distributed computing environment that includes a server cluster having a plurality of computing nodes communicatively connected via a network. Each computing node within the server cluster includes one or more virtual hosts, one or more containers operating on top of each virtual host and an application instantiation, operating on top of a container, communicatively coupled to a persistent storage medium. Each virtual host instantiates, and is tied to, a unique virtual internet protocol address that is linked to the persistent storage medium on which resides the application state data.

Abstract: Application instances can be virtualized and operate in a fault tolerant and load-balanced means across a cluster of servers while still maintaining access to a common pool of data. Each application instance is instantiated so to operate on top of a virtual host that possesses a distinct virtual Internet protocol address. Each node within a server cluster environment can possess one or more virtual hosts wherein upon server failover the virtual host and its associated virtual Internet protocol address can be relocated to another server without disturbing the instantiation of the application on the virtual host.

Abstract translation: 应用程序实例可以虚拟化，并在跨服务器集群的容错和负载平衡的手段中运行，同时仍保持对公共数据池的访问。 每个应用程序实例被实例化，以便在具有不同虚拟Internet协议地址的虚拟主机之上操作。 服务器集群环境中的每个节点可以拥有一个或多个虚拟主机，其中在服务器故障转移时，可以将虚拟主机及其相关联的虚拟因特网协议地址重新定位到另一个服务器，而不会干扰虚拟主机上的应用程序的实例化。
