Embodiment Construction

[0023]Examples of the invention relate to devices for use on heterogeneous data networks that support multiple data communication protocols. Such a heterogeneous network is a single physical network, such as Ethernet, composed of multiple logical networks, such as an IPv4 network and an IPv6 network. The device has a mode of operation for multicasting a respective query packet on the data network, the respective query packet using a respective protocol of a plurality of protocols. In the present invention, at least a specific one of the respective query packets includes an indication that the device supports multiple protocols. For example, the device comprises a UPnP compliant component for querying the network according to IP multicast. The protocols include, for example, IPv4 and IPv6. The UPnP component is configured to send a specific query packet with an indication that said component supports IPv4 and IPv6. Preferably, the specific query packet comprises an SSDP pack...

Abstract

A dual-stack UPnP-compliant device supports both IPv4 and IPv6. The device uses the SSDP protocol for discovery based on IP multicasting. The device sends SSDP query packets that comprise an indication that the device supports both IPv4 and IPv6. The indication is accommodated in an option field of the packet. A responding dual-stack device responds either to the first query packet that arrives or responds to only the query packet of IPv6.

Description

technical field [0001] The invention relates to an electronic device having an operating mode for multicasting query packets over a data network supporting multiple data communication protocols. The invention also relates to configuration software and a method capable of configuring an electronic device. Background technique [0002] Universal Plug and Play (Universal Plug and Play UPnP) is a technology widely used in open network architectures in the industry, which is designed to enable simple and dedicated communications. UPnP leverages Internet technology and extends it for unsupervised home networking. UPnP is designed to control household appliances, including home automation, audio / video, printers, smart phones, and more. UPnP distinguishes between control points (Control Points CP) and controlled devices (controlleddevices CD). The CP includes, for example, a browser running on a PC, a wireless keyboard, etc., which enable a user to access functions provided by t...
