1 TTM Futures II RIPE NCC 1 1

2 The story so far... TTM - Initial design in Became a service in Measures Delay/Loss/Jitter/Traceroute 10 years on - time to rethink! 2 2

3 Assumptions Bandwidth is expensive Measuring applications isn t interesting Subscriber lines are slow Internet is poorly connected Real-time traffic engineering cannot be done IPv6 not on the horizon Problems Low perceived benefit to TTM hosts Complex results presentation Needs GPS antenna Clustering of probes Ageing and shrinking of network 3 3

4 What have we done? RIPE52 - Istanbul - Presentation and discussion RIPE53 - Amsterdam - More discussion, and TT task force formed RIPE54 - Tallinn - Draft proposal made to this WG - NCC commits to build proof of concept Discussions on Task Force mailing list Input and feedback incorporated into this proposal! 4 4

5 Vision To expand and maintain the TTM network, increasing the value of the service to the community at large, and to the owners of the probes Enhance the TTM network architecture Enhance the TTM measurement architecture Improve - Reporting - Alarms - Admin and pricing 5 5

6 Network architecture NCC sponsored probes - At interesting locations - major AS or IX - Commitment from site to operate for at least 3 years - Selection will be a beauty contest at NCC discretion ISP sponsored probes - Sponsor-defined measurement mesh - Customised mesh for private application testing Lightweight probes - CBM proposal 6 6

11 Measurements Global one-way measurement platform - Continue to measure delay/loss/jitter/traceroute across full network - Add support for custom measurement meshes - Add support for OWAMP Allows for measurements on demand Allows for measurements outside our network - Data quality checks 11 11

12 Measurements General purpose platform for ad-hoc experiments - Unrestricted Time limited local, global, or mid-range Clearly defined Results should be made available to the community Available to interested parties (e.g. CAIDA) - Restricted Time limited local, global, or mid-range Fixed scope, defined by NCC/TTM community Results may be kept private Available only to test box hosts 12 12

13 Ad-hoc testing 13 13

14 Add new ad-hoc test 14 14

19 Reporting Simpler and clearer Fewer pre-generated plots - plots on demand - raw data 19 19

22 Reporting 22 22

23 Plots 23 23

24 Reporting Simpler and clearer Fewer pre-generated plots - plots on demand - raw data Monitoring trends - clearer presentation of long term performance changes 24 24

28 Reporting Simpler and clearer Fewer pre-generated plots - plots on demand - raw data Monitoring trends - clearer presentation of long term performance changes Data Quality Management - ensure plots make sense Combine TTM data with other services - e.g. RIS 28 28

29 Alarms User configurable Application and network Clearer presentation 29 29

31 New alarms framework 31 31

32 Alarms overview 32 32

33 Triggered alarms 33 33

34 Adding alarms 34 34

35 Configuring alarms 35 35

36 Admin and pricing Different payment options: - One large up front payment and no ongoing fees - Setup fee and recurring service fees - No setup, and larger ongoing monthly subscriptions Hardware lifecycle - 1, 3, 5, 7, 9 years? - what happens after this time? Model must ensure life and viability of network 36 36

37 Pricing model RIPE Network Coordination Centre Hardware 250 Setup

38 Where next? RIPE55 - Present this final proposal - Incorporate feedback - Seek consensus to proceed Begin implementation - Work becomes business as usual - Disband task force, update via tt-wg list - Continue to consult and invite feedback 38 38
