The wireless LAN is being employed from the traditional wireless LAN of non- real-time data to the wireless LAN gradual progress of the integrated service, users, to the service quality QoS Demand grow with each passing day [1 ],last different requirement the business one diversification about network, need the network to offer different service quality QoS assurances [2 ] to all kinds of users and business. IEEE802.11e standard is proposing for meeting the demands for the service quality of the mobile communication business of people, but in the network is larger or the network is topological under a frequent situation of the change, the suggestion value in the standard is often not enough to meet the business demand. How to set up the standard parameter value rationally according to the present network supports and business distribution situation, let adaptive network its, in order to realize the intersection of network and optimization the most of performance, it is one that need problem that solve urgently. ...

TCP/IP transmits the agreement that the data need on Internet, the realization among PC of this kind of network communications mode has been already complete, but factors such as the volume, price,etc. have limited the range of its application. So, the embedded systematic network communications based on TCP/IP agreement and Ethernet are designed as a hot topic at present. This system has realized in the embedded system taking TMS320DM643 of TI Company as the core, flow TS to the digital television transmission The signal is gathered and transmitted in Ethernet. Can realize and flow to the digital television transmission the transmission of the signal in the LAN, manage easily while utilizing this system. It is for the digital wired broadcasting system standard DVB-C in Europe that the signal source flows in the digital television transmission Digital wired TV signal. The network inserts the hardware to realize in the embedded system taking TMS320DM643 as the core, the network inserted the software to adopt TCP/IP NDK Network Developer’ s Kit that TI Company puts out to C6000 series DSP It is realized that the network develops and wraps up. ...
