基于串口管理的嵌入式委托代理實時性設(shè)計The Real-ti

開發(fā)委托代理（Proxy Agent）來解決非SNMP 設(shè)備的標(biāo)準(zhǔn)化管理，是目前普遍采用的手段。文章針對開發(fā)委托代理時遇到的串口通信實時性和系統(tǒng)資源利用不足的問題，提出了一種基于事件驅(qū)動和雙緩沖區(qū)的多任務(wù)串口通信的設(shè)計思想，結(jié)合相關(guān)控制算法實現(xiàn)了嵌入式委托代理的設(shè)計開發(fā)。該方案可用于網(wǎng)絡(luò)設(shè)備上委托代理功能模塊或嵌入式委托代理單元的設(shè)計實現(xiàn)，配合SNMP 管理站可以通過串口實現(xiàn)對非SNMP 設(shè)備的標(biāo)準(zhǔn)化管理。

【Abstract】 Presently proxy agent is widely used in implementing the normative management for non-snmp equipments. For resolving the problems of real-time operation and system resources using, this paper introduces a design idea of multitask serial communication which based event driven and double buffers. With some correlative control arithmetic, the project achieves the development of embedded proxy agent and can be widely used in network equipments. Through serial interface, the proxy agent achieves the normative management for non-snmp equipments with SNMP manager.
