Filter rules : allows the selective filtering or blocking of packets as they pass through any of the interfaces 過(guò)濾規(guī)則:當(dāng)數(shù)據(jù)包穿過(guò)網(wǎng)絡(luò)接口的時(shí)候,允許有選擇的過(guò)濾或阻塞數(shù)據(jù)包。
This protocol realized selective filtering, transmission latency and jitter control, adaptive adjustment, and not only meet system's request on accuracy and consistency but although filter most messages and increase scalability 此方法不僅實(shí)現(xiàn)了系統(tǒng)的可擴(kuò)展性,而且實(shí)現(xiàn)選擇性過(guò)濾、傳輸延時(shí)和不穩(wěn)定性控制及自適應(yīng)調(diào)整,使系統(tǒng)在保證精度的前提下最大限度的進(jìn)行信息過(guò)濾。
