The Design And Key Technologies Of Tactical Internet

Taking control and advantage of information is the key to win the modern war and it has become the key contention point between both sides of the warfare. As the growth of battlefield's information detection and the advance of automatic computer command, the need for battlefield data is increasing continuously. In order to adapt to the battlefield data's collection, processing, display and distribution and to support the highly mobile command, the US army brought forward the concept and architecture of tactical internet, which is build on the base of the Internet. Tactical internet has aroused the attention of other countries military department.Tactical internet is a combination of wireless tactical radio, computer hardware and software, which is based on the technique of wireless self-organizing network, and it supports TCP/IP protocol, and tactical internet controller and tactical multi-network gateway are two important device of tactical internet. Construction of tactical network needs to solve many key technical problems such as the changing of topology, network integration, expansibility, security, etc. These problems are all hot research topics of the tactical internet.The wireless network devices of our military now can't fulfil the need of tactical internet's special demand for performance, capacity, fault-tolerance, security and robustness. The main problems are the complexity of communication system,the diversity of wireless radios, the low rate of data exchanging, the difficulty of interconnection of different networks. To establish the tactical network has become the stringent need for the construction of our military's information transformation.This paper focuses on the need for the construction of our military tactical internet, based on the practical wireless tactical devices, studies the architecture and key technique of tactical internet. The main content is the construction of regiment-level tactical internet. Referencing the US MIL-STD-188-220B protocol, using the ultra-shortwave radio devices which are popular equipped in our military, the scheme includes the architecture, protocol stack, the design of internet controller and multi-network gateway, tactical radio, network management, security, etc.
