【摘要】：隨著衛(wèi)星網(wǎng)絡(luò)在應(yīng)急通信中的應(yīng)用,衛(wèi)星終端業(yè)務(wù)的種類不斷增加,業(yè)務(wù)流量可瞬間增大,具有明顯的突發(fā)性,終端上的數(shù)據(jù)流量數(shù)據(jù)呈現(xiàn)出自相似性。利用時(shí)間間隔服從重尾分布的ON/OFF疊加模型產(chǎn)生衛(wèi)星終端的自相似業(yè)務(wù)流量,并討論了自相似業(yè)務(wù)流量輸入對(duì)衛(wèi)星終端的丟包率、時(shí)延和時(shí)延抖動(dòng)的影響以及對(duì)有效帶寬的需求。通過(guò)仿真,得出了網(wǎng)絡(luò)終端業(yè)務(wù)丟包率、時(shí)延、時(shí)延抖動(dòng)與系統(tǒng)緩存之間的關(guān)系,在此基礎(chǔ)上,提出了減少時(shí)延、降低丟包率的思路,在帶寬和緩存受限的情況下,為信息的高效傳輸提供了理論依據(jù)。
[Abstract]:With the application of satellite network in emergency communication, the types of satellite terminal services are increasing, and the traffic can be increased in an instant. The self-similar traffic of satellite terminal is generated by time interval service from the heavy-tailed ON/OFF superposition model. The effects of self-similar traffic input on the packet loss rate, delay and delay jitter of satellite terminal and the requirement of effective bandwidth are discussed. Through simulation, the relationship between packet loss rate, delay, delay jitter and system cache of network terminal services is obtained. On this basis, the idea of reducing delay and packet loss rate is proposed. It provides a theoretical basis for the efficient transmission of information.
