  6. 6. Why we deployed wide area exchange? 5
  7. 7. 6 To solve the bad roaming experiences
  8. 8. Traffic handling in a Mobile Network Mobile Core Backbone The Internet SGW SGSN PGW GGSNGTP Tunnel Nationwide IP backbone is used
  9. 9. Traffic handling in a Mobile Network (Roaming environment) GRX/IPX The Internet SGW SGSN PGW GGSNGTP Tunnel GRX/IPX Indonesia Japan We use GRX/IPX(Transit provider) instead of the own IP backbone
  10. 10. Traffic handling in a Mobile Network (Roaming environment) GRX/IPX The Internet SGW SGSN PGW GGSNGTP Tunnel GRX/IPX Indonesia Japan Heavy latency caused by the Inter-GRX AMS -IX Netherland
  11. 11. Let’s think about TCP! 10ms latency brings 1/10 throughput Data Communication Packet Acknowledgement Packet Acknowledgement TCP Handshake
  12. 12. Test environment 11 The Internet WiFi Linux+Squid(Proxy) With 100ms Latency (using tc) Linux+Squid(Proxy) with No Latency Web server We know how latency affects throughput iPhone 6s
  13. 13. Test Result 12No Latency +100ms latency
  14. 14. 13 Latency is important factor for Voice Source : ITU-T Recommendation G.114 (05/2003)
  15. 15. 14 How do we handle VoLTE calls!? General GRX’s Latency
  16. 16. Solution? 15
  17. 17. Solution? 16 Peering!!
  18. 18. MNOs’ roaming via GRX MNO A MNO B GRX is a BLACKBOX SGSN Home GGSN GRX s Network ?
  19. 19. Our concept : Direct Connection Direct peering brings better connectivity MNO A MNO B
  20. 20. GRX s architecture 19 BGP BGP BGP BGP GRX is inter-net for Mobile Network Operators It is closed/Private network but used technology is completely same as “the Internet”. Source: IR.34 IPX Model, GSMA
  21. 21. GRX s architecture 20 BGP Let’s introduce the “peering culture” to the roaming world
  22. 22. Connection Type Image Relationship Payme nt Prefix exchange Connecti on Transit = GRX/IPX Rely on Upstream Yes Upstream provider will provide fully reachability to the network 1:1 Peer Private Equal footing No Exchange own NW prefixes each other 1:1 Public =RPX Equal footing No Exchange own NW prefixes each other over the public exchange 1:N ISP A (Upstream) ISP B (Downstream) ISP A ISP B ISP A ISP B ISP C ISP D IX Transit vs Peering IX Port cost is needed Transport cost will be splitted. User will pay to Upstream provider
  23. 23. Only Problem 22 Telco people do not know the peering world!
  24. 24. Bravest companies 23 Taiwan Mobile Taiwan AIS Thailand Telkomsel (Telin) Indonesia SoftBank Japan
  25. 25. 24 Speed Test result: 3G 4-5 times faster than the connection over GRX/IPX 0 2 4 6 8 10 12 0 200 400 600 Throughput (Mbps) RTT (ms) Downlink 0 0.5 1 1.5 2 2.5 0 200 400 600 Throughput (Mbps) RTT (ms) Uplink BBIX BBIX GRX GRX
  26. 26. 25 Speed Test result: 4G 0 5 10 15 20 25 30 35 40 0 100 200 300 400 Throughput (Mbps) RTT (ms) Downlink 0 2 4 6 8 10 12 14 16 0 100 200 300 400 Throughput (Mbps) RTT (ms) Uplink BBIXBBIX GRX GRX Doubled throughput on 4G/LTE network
  27. 27. Case in this country 26 Telkomsel Below 10MbpsOver 40Mbps XL Big improvement!!
  28. 28. Case in Korea Faster than the local environment J 27
  29. 29. 28 Taking you forward to VoLTE era Smart IX’s Latency General GRX’s Latency
  30. 30. Next step 29 • IRR Database for Roaming • DNS Server • Local breakout Utilize the know-how of the Internet backbone operation
  31. 31. No Peering, No Internet
