ETSI BSM Performance Management Questionnaire Performance monitoring of broadband networks is an important aspect of overall network management in order to ensure service provision. The ETSI Broadband Satellite Multimedia Working Group (BSM WG) has set up a Special Task Force (STF) to create standards for Network Management and is seeking inputs from satellite network operators, manufacturers and service providers on the status and future direction of Performance Management especially in satellite systems. In particular, the nature of any performance metrics employed, whether at a basic level or at a higher protocol (e.g. ATM, IP) level is sought. Therefore your responses to the questions below are invited. Please feel free to forward this questionnaire to other interested parties. This questionnaire is split into 3 parts. You are invited to reply to all 3 parts but please do respond even if you have no comments to some of the questions. We will be happy to accept partial replies but we would particularly welcome replies to Part 3 from all respondents. Further information about the ETSI STF can be found at: http://portal.etsi.org/STFs/STF_HomePages/STF344/STF344.asp Contact: mort.robert@gmail.com PART 1: HOW DO YOU MEASURE NETWORK PERFORMANCE ? 1. In which way do you monitor your network’s performance: a. Manual intervention: e.g. Installation time, Trouble tickets, callouts (for service), average help desk call duration b. Availability of other network equipment? e.g. sat. terminals, hub station, routers etc. c. Hardware-level parameters e.g. transmitter/receiver parameters, satellite link availability/ quality, bit rate…… d. Basic traffic parameters data rate, delay, queue parameters, frame parameters? e. IP-level traffic parameters? throughput, QoS, packet delay, loss etc. f. Any other? 2. g. How are the equipments/services sampled for monitoring (random selection, all) and over which time frames (minutes, days, weeks)? Do you foresee a need for future enhanced network performance monitoring and in which way? E.g. for multiple services, to satisfy SLA’s, or for 3. 4. internal performance guarantees? Do you use any IP-based or other protocols for performance monitoring? e.g. SNMP, RMON, IPFIX Do you use SNMP MIBs for transferring performance data and which parameters (OIDs), or else what process is used? PART 2: DO YOU PROCESS AND SHARE THE DATA (e.g. with service providers)? 5. Is any further processing of performance statistics done centrally and what is its nature? 6 Do you provide any access to performance data to external third parties (e.g. ISPs, Users). If yes: a) What type of data do you provide? E.g. SLA reporting or other performance guarantees? b) Which standards (e.g. protocols etc.) do you use for this external interface? PART 3: SATELLITE PERFORMANCE STANDARDS 7. Do you favour standards-based solutions for network performance (as compared to proprietary solutions)? And why? 8. 9. To what extent do you consider that there are appropriate standards available? Do you have any suggestions for aspects of performance monitoring of satellite networks that would benefit from more standardisation? Any other comments?
