MPLS Adoption Drivers

   Need for converged network to handle increased
                                                  needs.
   operational complexity and remote connectivity needs
   Class-of-service and full-mesh connectivity to handle
   specific applications – e.g. VOIP.
   Reduce total cost of ownership.

What is MPLS ?

   Multiprotocol Label Switching (MPLS)
                                                   tag switching
   - Invented by Cisco in 1997 and based on their “tag-switching” technology
     to to improve the forwarding performance of ATM switches

   - Forwards packets based on labels so packets are switched, not routed

   - An IETF approved technology for controlling the flow of network traffic
     on Layer 2 (Frame) and Layer 3 (IP) networks.

   - MPLS complements, rather than replaces, existing network protocols.

   - Deployment of MPLS yields significant benefits to both the network
     provider and the end user.

 Terminology

   MPLS – MultiProtocol Label Switching
   Customer Edge Router (
                g           )
                        (CER) – Router at customer site that interfaces
   with the WAN
   Provider Edge Router (PER) - This is the router at the carrier’s edge
   sometimes referred to as the Access Router
   A      R t           Carrier Access Router
   Access Router (AR) - C i A          R t
   P router - Backbone router or switch in the carriers network
   Label - Part of MPLS header that identifies the VPN
   QoS - Quality of Service – an overall or end-to-end experience
   CoS - A methodology to affect QoS

 How MPLS Works
                                                            Customer Site #2
                                         Customer Site #1



- IP Backbone is MPLS enabled
- Customer Edge Router passes IP
  packets to Provider Network

- Provider Edge Router applies MPLS
  label to packet
    be o p c e

- Complete path to destination address
  is determined across the core
  network. (LSP – Label Switch Path)

- Individual Packets are forwarded
  across the network based on MPLS
  Label and Label Switch Path.

- Provider Edge Router (egress) strips
  off MPLS label and forwards IP
  packet to destination customer edge
  Router

Page 20     Title
What is Class of Service (CoS)?

    CoS is the ability to prioritize one type of traffic over
       th      dt h               l   l f            th t th t ffi
    another and to have some level of assurance that the traffic
    and service requirements can be satisfied.


    CoS does not create bandwidth – it allows a customer and a
    carrier to more efficiently manage bandwidth according to
    application demands.


    Key CoS parameters to be managed /controlled are:
    bandwidth, delay, jitter and packet loss

Why is CoS Needed?
Application demands

    Important applications such as Voice over IP, video-conferencing, and
    mission critical ERP (SAP) have strict delay and guarantee requirements
    to perform properly.

    information that cannot tolerate unpredictable losses.

Solution
•   The enterprise network must be designed with the ability to
    differentiate traffic and enable different service levels for different users

How can we achieve Quality of Service?

          By applying several traffic mgmt techniques in the customer
          site router and the carrier network a quality solution is created.
 Classification                                          Traffic Shaping
 •   Classification of packets into different lists is   •   Queues the access traffic
     done in the customer router based on customer
     requirements                                        Fair Queuing
                                                         •   Provides minimum bandwidth guarantee to
 Marking                                                     each class. One queue used for each class
 •   Controls the amount of traffic accepted for each
     class                                                  g

                                                         •   In case of congestion, traffic of the lowest
 Policing                                                    priority class is discarded first
 •   Discards the excess traffic

     MPLS/VPN - Security Characteristics
                 MPLS offers Security Similar to Frame Relay
VPN route uniqueness and segregation
•                                            VPNs
      Route Distinguisher (RD) - Qualifies a VPNs’ IPV4 routes
•     Virtual Routing & Forwarding Tables (VRF) – Each VPN’s routes stored in
      separate tables
•     Route Targets (RT) – Used to control iBGP distribution of a VPN’s routes to its
      VRFs. (iBGP with multiprotocol and community attribute extensions)
VPN traffic segregation
•     IGP LSPs connect ingress/egress PEs
•     MPLS label stack: Inner label controls VPN connectivity; Outer label controls
         i hi      k                i      /       PE    d li i            df
      switching packet across core ingress/egress PEs and eliminates need for core to
      carry VPN routes
VPN membership controlled by AT&T Provisioning
•                                        g
      Customer interfaces on PEs are assigned to that customer’s VRF
•     Unique Route Distinguishers are assigned to customer routes
•     Unique Route Targets are assigned to VRFs to control distribution of cust’s routes
•     Customers are unaware of the RDs and RTs associated with their VPN




    Page 31                  Title
Review of Security based on RFC
4364, 2547

 Customer VPN interfaces and routes are hidden from all other
              Internet.
 VPNs and the Internet

 VPN membership is determined solely by provisioning.
 Customers can not become a member of another VPN based on
 the type of traffic they send
 - VPN spoofing, or “label spoofing” are not possible
                                            connections.
 Source address assurance (SAA) done on MIS connections
 Management Access Control

Customer Example #1 – Integrated Data
/Voice VPN
 Customer Business: Education. This New Jersey based Company is a leading provider of career education and
 training, graduating more than 8,000 students for technical positions in a variety of fields

 Original Networking Solution: The Schools were acquired either individually or as a corporate group. In either case,
 each School had its own small standalone solution for wide area network and voice/phone services. There were no
 networks or advanced technology systems. Corporate HQ had an old Avaya Merlin Legend and the schools had a
 hodgepodge of Internet access and phone systems from various vendors. There was a need for seamless connectivity
 and an advanced voice over IP solution with CPE to support

 New Solution Summary: An integrated data and voice networking solution supporting 23 company campuses across
 the United States. AT&T, with Avaya and Office Solutions, Inc. (OSI) , are providing Avaya IP Telephony over AT&T
 MPLS-PNT with Managed Routers and Class of Service. Equipment will be located within an AT&T Internet Data Center
 (Secaucus, NJ IDC), as well on the customers premise. The IDC is now their Data Center, hosting all of this customer’s
 mission-critical educational and business applications. The AT&T IDC houses an Avaya S8700 Media Server fully

 LSPs. All are running on the S8700. Should it or the link fail, the S8300s are Local Survivable Processors, which
 become live and take over local support until the link to the S8700 is restored. The AT&T solution also supports this
 customer’s business continuity plan, helping to ensure access to critical networking applications in the event of a
 disaster.

 AT&T integrated capabilities designed by Office Solutions Inc., an AT&T Alliance Channel agent, will intelligently
 distribute voice, data, and video communications among this customer’s campuses. This AT&T Alliance Channel agent
 complemented and enhanced AT&T's capabilities with specialized skills in network design and deployment. Also
 included was web site design and development, communications equipment expertise and management, application
 integration, and customer training
