New Services from theRIPE NCC

Henk Uijterwaal

RIPE NCC New Projects Group

NANOG-26, Eugene, OR

September 14, 2014


Outline

  • 2 services from the RIPE NCC

    • Test Traffic Measurements

    • Routing Information Service

  • Follow-up on talks at the Winter 2000 meeting


Part 1Test Traffic Measurements


TTM 101

  • Project to do performance measurements on the Internet

    • Delay

    • Loss

    • Routing

  • One way, active, “real” traffic

  • Inter-provider networks only

    • Hard for individual provider

    • Techniques can be used for internal networks though

  • Scientifically defendable, well defined standards

    • IETF IPPM, RFC’s: 2330, 2679, 2680, ...


TTM Service Goals

  • Black box

    • No configuration by the user

    • No user access

    • Guarantees well-defined environment for the measurements

  • Easy to install, little maintenance

  • Available to the entire community

    All you have to do,

    is to look at the results


Test-box Locations


CDMA Clocks

  • Independent clock source necessary

  • Installing a GPS clock is not always easy

  • Any alternatives to GPS?

  • CDMA

    • 3rd generation mobile phone standard

    • Phones needs a time signal

    • GPS Sync’ed base stations broadcast time signal

  • Can this be used for TTM?


CDMA Clocks

  • Yes! Same accuracy

  • Praecis CT

    • “Phone without speaker, mike and keypad”

    • http://www.endruntechnologies.com

  • Works everywhere your cell phone works

  • Simply mount on a wall

    • $0.02 installation costs


Alarms and near real-time plots

  • So-far, 6-30 hour delay between collection and plots on the web

  • All kinds of reasons why this is too slow:

    • Angry customer

    • Alarm from the box

  • Interface for this, recent plots, few minutes delay

    • Public Demo: http://tt01.ripe.net:10259/

  • Also gives access to configuration and status information


User Interface


Current Measurements

Rate, target, packet size

Status

Who set this up:

TTM Crew

You (somebody at your site)

They (somebody at the other side)

User Interface

  • Data volume (bits/second)


Daily report


Daily Report (2)


IP-Delay Variations or Jitter

  • For some applications, the absolute delay does not really matter

  • However, packets should arrive with constant intervals

    • Voice over IP

    • Video on demand

  • Metric and Plots


Trends

  • Delay over 6 months

     Night Morning Afternoon  Evening

  • Content provider with new customers

  • Intended for capacity planning

Median Delay

April 1

November 1


IPv6 version

  • IPv6 networks so-far

    • Tunneled over v4

    • Performance monitoring was an afterthought

  • Several native IPv6 network now operational

    • Interested in performance measurements from the start

  • Use existing products: RIPE NCC TTM

  • Porting

  • -testing, production version by December


Bandwidth

  • The next measurement to be added

  • 2 Parameters:

    • C: Total Capacity

    • A: Available Bandwidth

  • Method based on packet dispersion

  • Available on the box


Part 2Routing Information Service


RIS 101

  • AS1’s NOC gets a user complaint:

    • “Last night, I could not reach www.x.com.”

  • AS1’s NOC looks at the current routing tables

    • “Well, it works now”

Router

AS2

AS5

AS1

www.x.com

User

AS3

AS4


Motivation

  • Something is wrong with your routing

  • Current tools:

    • Log in to your router

    • Use a looking glass on other routers

  • Problems:

    • How to find right looking glass?

    • What if the looking glass cannot be reached either?

    • Accessing multiple LG’s takes a lot of time

    • No history mechanism

  • Solution: Routing Information Service (RIS)


Goals of the RIS

  • Set up route collectors that collect BGP announcements between AS’s

  • Time-stamp and store in a data-base

  • Set up interactive queries to database

    • Giant looking glass with history

    • Network reachability from other networks

  • Provide raw data and statistics

    • for reality checks, RRCC project

    • to generate trend analysis

  • Available to the Community


9 Route Collectors

RIPE NCC

LINX

AMS-IX

SPINX

CIXP

VIX

Netnod

MAE-West

NSPIXP2

200 peering sessions

Route Collectors


Growing by about 250/month in 2002

More and more sites are multi-homed

AS’s seen


CDF for the number of peers


Simple queries

  • AS by time

    • RIB for an AS at a given time

    • Announcements since then

  • Prefix by time

  • AS in use

    • Is your AS seen anywhere?

    • Startup, registration

  • Plots

    • Number of updates

    • Prefix distribution


Hyperlinked

    • Loopback

    • RFC1918 space

    • Class D/E-space, …

  • Usually private addresses leaking into the public space

  • Daily list with prefixes and origins

  • Reverse approach:

    • List AS’s and prefixes

    • Warn if something happens to them

  • Prototype RIPE44
