    TELEHOUSE Introductions
    Purpose of this webinar
    What is the Internet?
    What is Internet traffic mean?
    How do ISPS connect to each other?
    What are Internet Routes & How do they Work?

  • Peering 101: Purpose
    • Educate
    • Introduce this valuable network resource
    • keep folks informed about this valuable resource
    • Utilization
    • Not just for Large ISPs
    • Resources
  • Who is TELEHOUSE?
    4
    • Parent company, KDDI.
    • Consolidated revenue $34B.
    • Total IT Solution – NYIIX 1996 / LAIIX 1998

  • Peering 101: What is the Internet?
    5
    • NOT a single Network!
    • NO one owns it.
    • NO central organization to admin or monitor
    • Over 36,000 ISPs – autonomous networks
    • Internet - multiple autonomous networks Somehow connected and make work !!!

  • What is Internet Traffic?
    6
    BGP
    Border Gateway Protocol
    I’m on ISP-B
    Mom on ISP-A
    e.g.
    e.g.
    Exchange:
    Internet Traffic
    between two different ISPs
    (or Networks)
    Copyright Telehouse America 2010
  • How do ISPs connect to each other?
    7
    • Transitprovides full global Internet routes* or access to all IP addresses
    • Peeringprovides partial Internet routes* or access to limited number of IP addresses.
    costs money.
    VS.
    Transit
    Peering
    (*) Routes are basically addresses
    Copyright Telehouse America 2010
  • What are Internet routes?
    • Each ISP has: -Code Name (ASN) Autonomous System Number -owns routes or addresses - similar to ZIP code / street address relationship.
    • IP Address space e.g. 192.31.100.0/24 (254 addresses)
    ZIP
    12345
    ISP-A
    ASN: 12345
    10 Main St.
    25 Wood Ave.
    192.31.100.0/24
    193.11.77.0/24

  • How do Internet routes work? (Inbound)
    To Receive Traffic…
    • An ISP has to announce (BGP) its routes (or addresses) to the Internet in order to receive the traffic destined to the route.
    ISP-A
    I have the route.
    Send traffic to that route
    to me!
    Internet
    Announces
    BGP
    e.g. 192.31.100.0/24
    9
    Copyright Telehouse America 2010
  • How do Internet routes work? (outbound)
    10
    To Send Traffic…
    • ISP must have full routes announced (BGP) to the Internet and keep them in its routing table to ensure global reachability to its customers.
    • Its routers make a routing decision based on its routing table.
    Where is the destination route in my routing table? 192.31.100.0/24
    Send the traffic to port 1, slot 2, on NY#1 router
    Found it!

  • Transit vs. Peering
    11
    The best network architecture:
    • Combines transit and peering
    Copyright Telehouse America 2010
  • How an ISP/YOU, well architected network, connects to the Internet
    12
    • Minimize (bps) Transit & Max Peering traffic
    Standard ISP architecture:
    Partial Routes to/from “The” ISP (*) A, B, C, …. Z
    Full Routes
    B
    A
    ISP/You
    Transit
    Peering
    Tier 1 ISP
    D
    C
    E
    Z
    Pay $$$
    Free
    Large (Tier 1)
    Provider(s)
    (*) When peering with ISP-A, you can get routes from/to ISP-A only
    (partial routes)
    Regional or local providers
    Copyright Telehouse America 2010
  • What is Peering?
    Peering is simply the settlement free exchange of internet traffic.
  • Benefits? ….saves money
    Transit costs money….Peering is FREE!
  • WHY Peer?
    15
    • Free – averages down Transit costs
    • Routing options
    • Less latency

    ISP-C is multiple ISPs away

  • Who Peers & Who Benefits?
    • Large ISP’s/businesses can more readily
    access niche, regional traffic.
    • Small to medium size (traffic) businesses
    YOU
    can access the mainstream traffic, as well as
    niche, regional traffic too.
  • Benefits? ….increased network reliability
    • Improved Connectivity: Meeting at the Layer2 switch
    • Averaging down of bandwidth costs: Exchange traffic directly and avoid travel over paid bandwidth
    • A Plethora of Routing options: diversity of routes and traffic
    No longer restricted to just ISP’s and Telecom Providers!
  • Peering Types
    18
    Bi-Directional: Exchange the same amount of traffic
    Uni-Directional: Content heavy to Eye-ball heavy
    Copyright Telehouse America 2010
  • Peering Types
    19
    Bilateral: Selective based on business decision
    Multilateral: Easy peering with open peering policy
    via Route Servers
    1 ISP
    Multiple ISPs
    Copyright Telehouse America 2010
  • Peering Types
    20
    • Over 300 known Internet Exchange Points (IX) in the world.
    • Operated by profit or non-profit organizations.
    • Carrier neutrality is a key to success.
    Copyright Telehouse America 2010
  • Public IX Platform
    21
    • Layer 2 Switch platform (today’s mainstream)
    • Peer on the same broadcast domain
    • Optional route servers for multilateral peering
    Copyright Telehouse America 2010
  • Public IX Platform
    22
    • L2 Switch platform has been proven.
    - Peering protocol (BGP) requires L2
    - Up to 10G Port Wire-speed guaranteed
    - Optional jumbo frame for optimal MTU
    - Optional VLAN for private peering
    - Readily Scalable to higher speed
    (40/100G)
    Copyright Telehouse America 2010
  • Public IX Operation Issues
    23
    • Not so secure (on the same b’cast domain)
    - Your traffic may be affected - VLAN is not practical - Limited to 4,094 VLANs (e.g. 120 x 120 / 2 = 7,200!)
    - Difficult to manage
    Copyright Telehouse America 2010
  • Public IX Operation Issues
    24
    • No MTU Optimization
    - Low speed Ethernet use MTU 1,500 - Higher speed Ethernet opts for > 1,500 - There is no agreeable MTU size - Still use MTU 1,500 for this reason
    Copyright Telehouse America 2010
  • Public IX Operation Issues
    25
    • No Traffic data per peer
    - ISP wants to know traffic per peer
    - SNMP only shows traffic per physical port
    - sFlow? But it is on sampling basis.
    Copyright Telehouse America 2010
  • Public IX Operation Issues
    26
    • No Traffic Engineering
    - If IX’s topology is triangle, traffic flows only via one particular path due to STP.
    - Traffic does not take the shortest path.
    Copyright Telehouse America 2010
  • Future Developments
    27
    • MPLS Based IX (proposed at NANOG 2002)
    - MPLX router based IX (not L2 switches)
    • Benefits
    Secure tunnel per peering session
    Optimal MTU per peer
    SNMP MIB per tunnel for traffic analysis
    Traffic Engineering (via RSVP)

  • Benefits? ….access to key internet players!
