Information

A domestic wireless communication command system provider needs to bridge LAN distributed in different locations to become a unified IP subnet through self-developed wireless communication system. No unified IP subnet. Routing protocol of wireless communication system used by private protocol implementation, the technical challenge is to come from within the local area network (LAN) attached directly to the communication controller of Ethernet packets, according to the message can filter out the forwarding address message, then this part of the packet payload to encapsulate communication controller on the wireless channel sent to the end. Considering the stability of the system and delivery time to the customer, the management system of the new module will directly use the original equipment management system, including configuration, management and control modules. The basic requirements of the system design are stable, reliable, efficient, flexible and open, so as to facilitate the upgrading of software and hardware in the future. The packet forwarding and filtering function of the system required to directly between articulated in the underlying drivers and TCP/IP protocol stack, and to keep compatible with the original TCP/IP protocol stack, so you need to developers of protocol stack, and driver's data structure and control principle are very familiar with, and to optimize the data processing in order to meet customer Performance requirements.

To save development time and get the best performance, the client took advantage of Coordinate's expertise in the underlying driver and TCP/IP protocol stack, adopted the packet forwarding and packet filtering software designed by Coordinate, and asked the company to optimize the original serial driver used to simulate the wireless network to achieve the best simulation results. With the joint efforts of both parties, the customer successfully completed the design and review of the system prototype within one month.  

Through cooperation with Coordinate company, customers can in the shortest possible time to complete the design of the system prototype machines and review, and using Coordinate company in VxWorks real-time operating system, software protocol stack and the professional knowledge of the underlying hardware platform, to avoid the common long familiar with process in the development process, and in a timely manner to the end user to provide the products that meet the performance requirements.
