【摘要】：隨著新協(xié)議的不斷涌現(xiàn)和網(wǎng)絡(luò)速率的迅猛增長,報(bào)文解析結(jié)構(gòu)在解析靈活度和解析速率上面臨挑戰(zhàn)。該文結(jié)合流水線設(shè)計(jì)和二叉trie樹查表思想,提出一種應(yīng)用于路由轉(zhuǎn)發(fā)的報(bào)文協(xié)議解析結(jié)構(gòu)(Parsing PipelineArchitecture for Forwarding,PPAF),通過構(gòu)建協(xié)議二叉trie樹來支持報(bào)文協(xié)議解析的靈活度,利用硬件多級流水查表提升報(bào)文協(xié)議解析處理速率,采用節(jié)點(diǎn)映射算法解決協(xié)議二叉trie樹節(jié)點(diǎn)到流水線映射過程中存儲(chǔ)資源不均衡的問題�；贜etFPGA平臺(tái)的仿真結(jié)果表明,相對于現(xiàn)有的高速解析結(jié)構(gòu),PPAF在處理速率和資源占用上取得較好的均衡的同時(shí),能夠提供基于接口的獨(dú)立靈活解析能力。
[Abstract]:With the emergence of new protocols and the rapid growth of network rate, packet parsing architecture faces challenges in terms of resolution flexibility and resolution rate. Combined with pipeline design and binary trie tree lookup idea, this paper presents a packet protocol parsing structure for routing and forwarding, which can support the flexibility of packet protocol parsing by constructing binary trie tree. Using hardware multilevel pipelining table to improve the processing rate of packet protocol parsing, node mapping algorithm is used to solve the problem of storage resource imbalance in the process of protocol binary trie tree node to pipeline mapping. The simulation results based on NetFPGA platform show that compared with the existing high speed parsing architecture, PPAF can achieve a better balance in processing speed and resource occupation, and can provide independent and flexible parsing capability based on interface at the same time.
