outline
Outline
  • 2 services from the RIPE NCC
    • Test Traffic Measurements
    • Routing Information Service
  • Follow-up on talks at the Winter 2000 meeting
ttm 101
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
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

cdma clocks
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 clocks1
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
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 interface1
Current Measurements

Rate, target, packet size

Who set this up:

TTM Crew

You (somebody at your site)

They (somebody at the other side)

User Interface
  • Data volume (bits/second)
ip delay variations or jitter
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
Trends
  • Delay over 6 months

 Night Morning Afternoon  Evening

  • Content provider with new customers
  • Intended for capacity planning

ipv6 version
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
Bandwidth
  • The next measurement to be added
  • 2 Parameters:
    • C: Total Capacity
    • A: Available Bandwidth
  • Method based on packet dispersion
  • Available on the box
ris 101
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”

motivation
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
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

Growing by about 250/month in 2002

More and more sites are multi-homed

simple queries
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

  • Prefixes not allowed by draft-manning-dsua
    • Loopback
    • RFC1918 space
    • Class D/E-space, …
  • Usually private addresses leaking into the public space
  • Daily list with prefixes and origins
bgp beacons
BGP Beacons
  • Prefixes intentionally announced at known times by each route collector
    • Announced at 0, 4, 8, 12, 16, 20 GMT
    • Withdrawn at 2, 6, 10, 14, 18, 22 GMT
    • Prefix 195.80.(224+n).0/24
    • N=0…8 for the RRC’s
    • Part of the RIS AS 12654
  • Intended for flapping and dampening studies
  • Active since 30/9/2002

MyAS
  • Currently: user has to visit our webpages
  • Reverse approach:
    • List AS’s and prefixes
    • Warn if something happens to them
  • Prototype RIPE44
