Research on QoS Monitoring for Public IPv6 Network Bearer Service SLA
公用IPv6网络承载服务SLA监测研究

After the demands for network bearer service SLA(NSLA) in NGI are analyzed,taking possible application scenarios of NSLA as well as new features of IPv6 into account,this paper defines four QoS parameters for IPv6 NSLA:IP packet transfer delay(IPTD),IP packet delay variation(IPDV),IP packet fail ratio(IPFR) and IP packet throughput capability(IPTC),where IPTC is suitable for characterizing the ability of IP network section ensemble to sustain a given traffic pattern.Packet recognition and clock synchronizat...
