Packet Clearinghouse IP Phone Project: Bill Woodcock

  http://www.pch.net/inoc-dba

  Putting up SIP telephones in NOCs in many ISPs
  Dial using AS numbers, want to complain about a problem at Genuity just
  pick up the phone and dial 1, speak to bill dial 42

  Many large ISPs participating, LINX has all their offices online
  already, many exchanges are getting involved

  Netnod just ordered 60 phones, every member ISP will get one

  It's simple, any SIP device will work, mostly using Cisco 7960s
  Cisco can be persuaded to throw them in free with a large order
  Started with 100 phones which were given out for free, trying to
  get more for those who can't get their own

  - Questions ?

    ? How is it funded

    It's not, it's kind of the open source alternative, soon it will be
    the only phone network in history with service on 7 continents
    SIP is just no that difficult, you can run your own phone company in
    your spare time


IXP Interconnect Case Study: Keith Mitchell, James Rice

  -Keith Mitchell-

  A year ago Keith gave a presentation on connecting exchange points
  A lot of overview coverered there, explains background
  From that the conclusions are that this can be good, but be very careful

  At Xchange point they have done this, with BT UK6X informally
  Have executed formal agreement with LoNAP

  Layer2 interconnect is very much in vogue, especially in the UK
  Seeing a lot of pressure to glue layer2 together, it's so much cheapear
  than doing it with routers
  It saves money, but is it smart ?
  A good idea for cost saving, not such a good idea with multiple
  exchanges on one metro
  Lets not connect everyone together witout routers

  XchangePoint and LoNAP been informally cooperating for a year
  Made a formal agreement about a week ago

  Have identified multiple connections modes, have implemented the first,
  a simple p2p vlan
  In the agreement there is a commitment to entering the modes if it
  works out, taking it a step at a time

  A block VLAN IDs unique to both parties asigned

  Gets scary doing this with multiple parties, only 12bit space

  Using 100 IDs, 40 XchangePoint, 40 LoNAP, 20 reserved

  All p2p, no public peering exchange addresses in use, 2 peers assign
  a /30 for a peering

  They don't do any settltment across the exchange, like a peering
  agreement

  Do people pay ?
  The terms are betwen the customer and operator they are connected to

  Resiliency
  You can't do spanning tree
  Could run different VLANS across the links
  Using manual configuration

  AUP
  Started writing, ended up with a very long list
  Decided to take the simple approach
  Any traffic across the connect must comply with the AUP at either end
  All traffic tagged
  All parties must know the rules at either end

  Service levels
  Layer2 stuff, you can only see the failure end to end, contact your
  operator for resolution
  Keep each other informed about tickets, etc

  Is this a legal agreement ?
  Not really, they have found a way to make it binding
  Termination notice period
  Have limits in place for costs sharing, etc

  Open Issues

  Do you extend your address space across the other exchange?

  -James Rice-

  Cisco use default VLAN 1, it can't be filtered and cant be disabled
  You decided therefore not to use it, your customers connect using it,
  this is not good .. Cisco, do something!

  LoNAP has a collector, ExchangePoint has a reflector!
  Wether or not to have a multilateral peering router is a good idea ?
  Should they participate in each others ?

  So far they have heard no rumblings of losing a customer who no longer
  needs to be at both exchanges
  Both exchanges have fairly different marketing strategies

  -Keith Mitchell-

  Problem with scaling broadcasts
  Switch vendors should provide a better solution for this

  Have been going for about a week, it's going OK, 10 VLANs up in the
  first week

  The agreement is in the public domain, please check first with Keith
  or James first though

  - Questions ?

    -Randy Bush-
    ? Complex layer 2 networks have reliability problems, you seem to be
    trying to reach a compromise for many reasons which are hidden. We
    know STP, etc have bugs, these things fail, you are trying to reach
    a compromise to solve a business need and it would be nice if next
    time you could reveal what is under the covers here, why you
    made some of the decisions, what were you trying to avoid, why you
    chose not to try those things? A real hell lies here and you are
    working hard to avoid it, others are walking into it and it would be
    nice to get explicit about this

    -Keith Mitchell-
    Some of this is covered in the presentation given last time, if we
    let this run for a while there will be more to tell next time

    -?-
    ? Are you running a seprete vlan for ipv6

    -Keith Mitchell-
    At the moment LoNAP doesnt do it
    XchangePoint is putting it on seperate vlans
    Anyone wanting to do dual stack on a router can support them on
    different interfaces

    -Bill Woodcock-
    This is the same methodology that has been used between Seattle IXP
    and the Seattle PAX, it works there

    -Keith Mitchell-
    I know its been done in the US

    -Bill Woodcock-
    Yeah, it works fine

    -Mike Hughes-
    Would you be interested in putting the do's and don'ts
    into BCP, share your gotchas, etc, this is new

    -Keith Mitchell-
    Yes, sure


IPv6 Policy Issues Update: Mike Hughes

  Mike and Netnod will write a document on getting address space for
  independent IXP services nets, so they are independent of a particular
  upstream
  You turn the classic relationship on its head as an IXP, asking customers
  for addresses

  Questions ?

  -Randy Bush-
  Why is that upside down ?

  -Mike Hughes-
  Kurtis asserted it this way, if you want to have the same fight as in the
  IPv6-WG please do it later ;)

  -Kurtis Lindqvist-
  Just a reflection, IXPs in several locations only get 0ne /48,
  not a problem space wise, but this is only one AS num they would rather
  have seperate blocks ..


-Mike Hughes-

RIPE NCC! We need a monitor on the stage for audio!


IPv6 Exchange Point Survey: Alexander Koch

  Been spending some spare time thinking about rolling out v6, has Juniper
  kit, it just works
  1 Cisco working in v6 BGP full mesh, a great surprise on this old box
  As they rolled out v6 in Europe and the US, many exchanges have v6
  assigments but nothing is happening, they support it but to what
  level?

  They see issues with exchanges in europe using eui64 adressing, this
  is not what we want to see, other exhanges running on 6bone space
  other exchanges doing it on a sep vlan

  What he wants to say is some small things about exchanges and how he
  would ask them to do it, make it work and make it work easier

  At many IXPs they use eui64, he has no problem with hex, but decimal is
  so much easier

  Seen that many IXPs put v6 on a seperate switch, you would have to use
  a specific connection, whats the point?

  XchangePoint doing VLANS all the way through, why ?
  Others doing it to stop interference in operational security, yet to
  hear of any problems with this though anywhere in the world!
  Many IXPs already doing this
  Some IXPs just do it the wy he would like everyone to do it, they
  offer ipv6 parallel to v4
  An argument we still hear is that some providers cannot do it, they
  have to do this with a test, these guys need anpther port anyway
  Cisco IOS versions lately are good, far more stable than previuosly
  try it out
  All exchanges consider offering it on the same VLAN!
  Those that need a new port will need it anyway
  More and more people will use the same router for v4 and v6
  Way more people will use v6 at the AMSIX, at DECIX it is getting
  bigger, dont put restrictions on this
  Push v6, put it in the same LAN

  - Questions ?

    -Bernard Tuy-

    ? Next time please have some slides, it is boring listening to
    10 minutes like this, this is interesting for us all, we like to see
    more information

    -Mike Hughes-

    Alexander can write up his thoughts and get them out on the list

    While we are here, of the EURO IX members, who have their details
    up ?

    About half of us then of those who are here

    -Bernard Tuy-

    Is it in the public area ?

    -Mike Hughes-

    Yes

    -Christian Panigl-

    ? Is there a benefit for the IXP in having them in the same VLAN

    -Alexander Koch-
    You can use a smaller router without VLAN trunking, this needs a
    different feature set with more bugs
    MCAST On a seperate VLAN, v6 should be on the same!

    -?-

    That made prove to people afraid of v6 that its not harmful

    -Bernard Tuy-
    It's not a matter of afraid, but about monitoiring, if you want
    to seperate monitoring you should use seperate monitoring

    -Christian Panigl-

    As an IXP operator there is therefore a benefit to seperate VLANS,
    it's a trade off
    We use a different VLAN mainly so we offer diferent AUPS on the
    diferent lans, we allow transit only in v6
    Eventually though the policies will converge

    News
    New site at RedBus, more nice pictures
    Private Gig interconnect
    New website with useful information, bandwidth stats, peering
    matrix, etc
    A recent question was the last time a non scheduled LoNAP happened,
    nobody can remember
    First IXP interconnect in Europe
    Until the end of February new members will not have to pay the joinup
    fee, cables run by LoNAP
    80% peering right now
    Looking glass on the website

    Most of that comes from MfN
    New customers: Marula, Associated Networks, Aeximous
    Connection policy, dont need a router housed with LoNAP, you can
    have a private circuit into one of the colo facilities
    v6 is on the todo list, none so far, want an indepedent allocation but
    dont currently qualify, getting that fixed this week,
    If you are interested in joining fill in the form on the website


  o LINX Chris Fletcher

    You know who we are, heres an update

    Usual stats, graphs, what we're doing with engineering, new network
    map, news on changes to billing doing some training work

    Traffic
    Last week peaked at 25Gbps
    http://stats.linx.net

    Members
    136

    Engineering
    Upgrade of Extreme switchesd to 10Gig
    Creating a 1010Gbps ring at the cire
    Started 1t6th Jan
    New blades needed 6 reloads did this on spare blades so downtime was
    very small

    Network Map
    2 seperate networks

    Billing
    Quite a big change
    Started usage billing in 2002
    Cost of inter site links depends on usage
    IX monthly income = variable charges
    Dont need to redict growth over coming year
    Fixed monthly inomne make cashflow work easily

    Required income / total usage = pounds per meg, for monthly charges
    Apply this to each port multiplied by the avg megs per second
    This guarantees the required income per month and fairly splits the
    cost among the members
    There is also a flat charge per port
    Higher charges > 75% usage on a port, ie 750Mb on a Gig port
    this discourages members filling a port and adding latency
    100Mbps at 50 Mbps = 752 pouns
    It is hard to say that a port costs a certain amount
    They have plans for a calculator
    Choice of monthly in arrears by direct debit, or quarterly in
    advance
    Advanced billing is based on an estimate
    Correction based on actual usage is applid next quarter

    Training
    Had this around for a while
    Came up with a framework of thisngs internet engineers need to
    know
    Spoke to universities and providers, universitiess interested, taken
    it on as a basis for courses
    LAIT  LINX Accredited Internet Technician
