    Abstract: Method, communication web service, web server, and client for providing communication service for IP devices via Internet, wherein the communication web service (CCL) is configured to be accessed by an adapter service of a local IP network via an outbound HTTPS-connection to a pre-defined URL pointing to a web server which provides the communication web service (CCL), wherein said adapter service is acting as a gateway for fieldbus tools located in the local IP network; and wherein the communication web service (CCL) is further configured to be accessed by a gateway IP device of a further local IP network via an outbound HTTPS-connection to the pre-defined URL pointing to the web server which provides the communication web service (CCL), wherein the gateway IP device is interfaced to a fieldbus connecting fieldbus devices; and wherein the communication web service (CCL) is providing a tunnel connection between the adapter service and a fieldbus device to provide a fieldbus tool access to a fieldbus device.

    Abstract: A relay apparatus (100) receives data from a first device (106, 103, 104) via a first network (105, 170, 140). The relay apparatus then receives a first request from a second device (102) via a second network (150, 160, 180), and sends a second request to the first network in accordance with the first request. Then, the relay apparatus sends, to the second device via the second network, data received from the first device prior to the first request being received, in accordance with the first request and a communication condition.

    Abstract: A method, apparatus, and system are described for a central station to allocate virtual IP addresses. A device service manager server (DSM) has a network access module configured to cooperate with two or more device service controllers (DSCs). The DSM serves as a central management station for allocating and assigning Virtual IP addresses to network devices to proxy communications for networked devices on a local area network (LAN) where each DSC resides. In some embodiments, various protocols may use UDP broadcasts to perform device discovery.

    Abstract translation: 描述了一种用于中央站分配虚拟IP地址的方法，装置和系统。 设备服务管理器服务器（DSM）具有被配置为与两个或更多个设备服务控制器（DSC）协作的网络访问模块。 DSM用作分配和分配虚拟IP地址到网络设备的中央管理站，以对每个DSC驻留的局域网（LAN）上的网络设备进行代理通信。 在一些实施例中，各种协议可以使用UDP广播来执行设备发现。
