Description

Network Performance Measurements in Internet Protocol (IP) Networks DOD has established a technical working group named the Global Information Grid (GIG) Quality of Service (QoS) working group (GQWG). One of the teams in this GQWG is charged with investigating methods for collecting and analyzing performance metrics in the DOD's global network. The performance metrics being considered are given in attachment (1). We are requesting vendor input regarding capabilities for network performance measurement and analysis using their specific products, whether hardware or software, for the metrics listed in attachment (1). Be specific as to the definition of performance metrics as implemented in your products and the related measurement methodologies. The results of the GQWG will guide DOD in future implementations. Input received before 6 July 2001 will be most useful for our consideration.

(ITU-T Y.1540) Jitter or One way IP packet transfer delay variation -- using the difference (IPTDmax-IPTDmin) during the measurement interval. The 95th percentile of these values is expected to meet the applications transport network objective. (ITU-T Y.1540) One way IP packet loss ratio -- expressed as a % of total packets lost/total packets sent. (ITU-T Y.1540) Throughput (ITU-T Y.1540) The total number of octets transmitted in IP packets that were successfully transmitted during a specified time interval divided by the time interval duration Availability (ITU-T Y.1540) IP Service Availability 100 Percent IP Service Unavailabililty (PIU) PIU The percentage of total scheduled IP service time that is categorized as unavailable using the IP service availability function IP Service Availability Function: IPLR > C1 IP packet severely loss ratio (ITU-T Study Group 13 D.958) The percentage of total scheduled IP service time that is categorized as severely loss state using the IP service severely loss judgment function to total scheduled IP service time that is categorized as available using the IP service available function IP service severely loss judgment function: C2<IPLR<C1; C1 0.75, C2 0.2
