FPGA-based multifunctional Internet-of-things gateway device

Abstract

The invention discloses an FPGA-based multifunctional Internet-of-things gateway device. The FPGA-based multifunctional Internet-of-things gateway device includes a Gigabit Ethernet interface module, a firmware storage module, a control module, a network data processing module, a clock module and a power source module. With the FPGA-based multifunctional Internet-of-things gateway device of the invention adopted, problems in secure connection between a large-scale local Internet of things, in particular, an Internet of things involving transmission of a large quantity of data, such as a video monitoring network, a management network and other front-end acquisition networks can be solved. The FPGA-based multifunctional Internet-of-things gateway device of the invention has a Gigabit Ethernet interface processing ability, supports bidirectional 16-channel static NAT, supports an international standard SIP traversal NAT function, has variety of filtering functions, is small in size, and is suitable for distributed access installation. With the FPGA-based multifunctional Internet-of-things gateway device adopted, a new solution can be provided for Internet-of-things connection involving high-definition images.

Description

technical field [0001] The invention relates to the fields of information technology, computer technology and network communication technology, in particular to an FPGA-based multifunctional Internet of Things gateway device used in a video surveillance network. Background technique [0002] In the era of the Internet of Things, household washing machines, induction cookers, TVs, community monitoring, and signal lights on the road will all become controllable terminals of the Internet of Things. There is a huge potential security problem. [0003] For example, a community network may include a video surveillance network, a smoke alarm network, a lighting control network, and a management network. These networks are all local area networks. In order to facilitate management, different types of networks are usually divided into different LAN segments and are independent of each other. However, the management network needs to manage other networks. Therefore, the management ne...

Problems solved by technology

Most of the building LANs are now connected directly with Layer 3 switches and routers. The management network is all exposed to other subnets, and other LANs can communicate with the management network without restriction. These communications may be normal information uploads, or It may be a network attack on the management LAN. This connection method has great security risks
