Protocol bridging method and device

Abstract

The invention provides a bridging method and a bridging device for a protocol and the invention is applicable to a digital household network. The method comprises the following steps: a received original network data packet is analyzed and data in a interconnection and intercommunication layer is taken out to generate a new network data packet; according to the transformation rules between the corresponding protocol of the original network data packet and the target protocol, a new network data packet is transformed into an abstract interlayer data packet which is irrelevant to the protocol; the data packet of the abstract interlayer is transformed into a target data packet corresponding to the target protocol. The device comprises a protocol transformation rule memory, a protocol metadata model memory, a protocol data packet analyzer, a protocol data packet converter and a protocol data packet matcher. In the invention, a source network data packet is transformed into an abstract interlayer data packet and the abstract interlayer data packet is then transformed into a target network data packet, thus realizing an interconnection and intercommunication as well as resource sharing among networks or among devices with different protocols.

Description

technical field [0001] The invention belongs to the field of digital home networks, in particular to a protocol bridging method and equipment. Background technique [0002] In recent years, with the rapid development of computer and network technology and the expansion of personal demand for informatization and digitization of family life, the concept of digital home network has been proposed. The so-called digital home network is to connect household devices into the same home network, adopt standard interconnection protocols, realize resource sharing internally, and realize information exchange externally through gateways and external networks. In order to provide users with intelligent, digital and information-based life. [0003] At present, the digital home network protocols at home and abroad mainly include: the foreign Digital Living Network Alliance (DLNA, Digital Living Network Alliance) agreement and the domestic information equipment intelligent interconnection a...
