  1. Niels Raijer presents

  2. Dynamic routing on Inmarsat interconnects

  3. Contents Current APNs What is an APN? Problems with traditional approach Introducing dynamic routing New APN layout Technical and commercial advantages Future APN developments

  4. Current APNs mvs.bgan.inmarsat.com (Burum/Amsterdam, majority of customers) mvsfr-usa.bgan.inmarsat.com (Burum/New York, one customer) direct-usa.bgan.inmarsat.com (Burum/New York, no customers)

  5. We’ll help you Confused?

  6. What is an APN? Name for customers to choose in LaunchPad Configured on Inmarsat GGSN, and “lives there”: Burum or Paumalu Has pool of IP addresses Traffic exchanged on interconnect POP:Amsterdam or New York

  7. mvs APN mvs APN 195.3.166.23 76.74.190.129 mvsfr-usa APN direct-usa APN

  8. Problems Routing for US-based customers is not optimal (traffic schould not cross the Atlantic twice) We fully depend on Burum GGSN now (not redundant!) We depend on capacity of Inmarst’s network rather than our own Redundant interconnects, but static routing

  9. Dynamic routing Exchange routing information between routers Routers tell each other: “If you have traffic for IP address a.b.c.d, send it to me.” More versatile than static routing Redundant in case of router or link failure (“Hey, can’t talk to router C any more -- I’ll delete all routes I learnt from him.”)

  10. Example of BGP routing table bganap-1.ams(M)-> get vrouter trust-vr route protocol bgp H: Host C: Connected S: Static A: Auto-Exported I: Imported R: RIP P: Permanent D: Auto-Discovered iB: IBGP eB: EBGP O: OSPF E1: OSPF external type 1 E2: OSPF external type 2 Total 177/max entries ID IP-Prefix Interface Gateway P Pref Mtr Vsys -------------------------------------------------------------------------------- *1499 195.3.167.103/32 tun.1 172.26.172.1 eB 250 15 Root *1531 195.3.166.98/32 tun.1 172.26.172.1 eB 250 15 Root *1496 10.11.64.68/32 tun.1 172.26.172.1 eB 250 15 Root *1455 195.3.166.111/32 tun.1 172.26.172.1 eB 250 15 Root *1018 195.3.166.108/32 tun.1 172.26.172.1 eB 250 15 Root *1738 195.3.166.118/32 tun.1 172.26.172.1 eB 250 15 Root *1530 195.3.165.119/32 tun.1 172.26.172.1 eB 250 15 Root *1505 195.3.166.117/32 tun.1 172.26.172.1 eB 250 15 Root [...] *1674 10.11.16.226/32 tun.1 172.26.172.1 eB 250 15 Root *1639 195.3.166.147/32 tun.1 172.26.172.1 eB 250 15 Root *1543 195.3.166.154/32 tun.1 172.26.172.1 eB 250 15 Root Total number of bgp routes: 97

  11. New APN layout Two APNs called ‘mvs.bgan.inmarsat.com’: one in Burum, traffic delivered in Amsterdam; one in Paumalu, traffic delivered in New York Dynamic routing to let Inmarsat tell us on what POP a customer is located Inmarsat sends traffic to closest MVS POP

  12. BGP route: GGSN tells MVS router ‘195.3.166.23 is here’ mvs APN mvs APN 195.3.166.23 76.74.190.129 195.3.166.23 BGP route: GGSN tells MVS router ‘76.74.190.129 is here’ BGP route: GGSN tells MVS router ‘195.3.166.23 is here now’ 195.3.166.23

  13. Commercial advantages Global APN name AND Global static IP address AND Lowest possible latency AND True, full redundancy

  14. APN developments mvsfr-usa.bgan.inmarsat.com is deleted direct-usa.bgan.inmarsat.com is merged into mvs.bgan.inmarsat.com any new customer APNs will all be logical APNs (old name: ‘ghost’ APN) optimization of Internet connections to reduce latency

  15. ЦТС AS 43666

  16. ЦТС AS 43666

  17. Conclusion MVS has a really sophisticated solution for routing traffic with Inmarsat! Unique: no other DP has this! Other DPs can do global APN or global IP or lowest latency, but not all three! APN mvs.bgan.inmarsat.com will be the true,redundant basis for new logical APNs
