Typical Carrier Ethernet Deployments

• Various Ethernet Service Definitions
   – Multiple Ethernet service offering with different SLAs

• Multiple Platforms for Service Delivery
   – Different vendors in core, metro, access
   – Ubiquitous availability of Carrier Ethernet carries a consequence
     of multi-vendor deployment

• Metro Ethernet vs Inter-Metro (PAN European
  Services

• Wholesale vs Retail Service Offerings

Challenges Enabling Carrier Ethernet Services

• Deployment of a new service
   – Customers need ubiquitous “Ethernet everywhere”, needs to be
     widely deployed
   – Provisioning, monitoring and billing challenges for shared
     services
• Leveraging Current Infrastructure
   – Need to upgrade existing legacy infrastructure (SONET)
   – Need to inter-work with current core (typically IP/MPLS)
• High Availability
   – Need to achieve the same performance as legacy services
   – E.g. SONET’s 50ms recovery time
• Security
   – Legacy technologies such as TDM, Frame, ATM and SONET
     were not as exposed to security vulnerabilities as Ethernet

Interoperability and Interconnect


     Carrier Ethernet Interoperability
               Challenges
             Michael Haugh




                     11
Service Provider Requirements For Interop.

Carrier are looking to deployment new CE enabling technologies
  are they are not typically single vendor dependent requiring
  interoperability. New CE enabling technologies include:
• Next Generation SONET (Ethernet over SONET)
• MPLS/VPLS
• Transport MPLS (T-MPLS) ITU G.8110
• 802.1ad Provider Bridges (a.k.a Q-in-Q)
• 802.1ah Provider Backbone Bridging (PBB a.k.a MAC-in-MAC)
• 802.1Qay Provider Backbone Bridging Traffic Engineering (PBB-
  TE)
• Fault Management Ethernet OAM/CFM
  802.1ag Ethernet CFM inter-working with MPLS-OAM




                               12
Interoperability / Inter-Working End-To-End




Access        Metro          Core
• IP DSLAM    •NG-SONET      • Primarily   Fault Mgmt
• CMTS        •Prov.Bridge     IP/MPLS
                                           • OAM/CFM
• WiMax       • PBB          •T-MPLS
                                           • Performance

                               13
MEF Certification and Interoperability

• Interoperability – major goal of the MEF
• Coexistence of certification and
  interoperability
• Certification being a worthwhile
  precondition to achieve interoperable
  implementations
• Specification options and performance
  aspects completely left open by certification




                       14
Carrier Ethernet Testing Methodologies (1)

• Functionality/Interoperability
  – Carrier Ethernet is maturing every day – devices
    must conform to standards
  – MEF has defined the protocols and the means of
    conformance and performance testing
• Inter-working
  – Carrier Ethernet metro technologies inter-working
    with legacy technologies as well as core networks
• QoS
  – QoS enforcement must be verified for mixes of triple-
    play traffic
  – Under real world traffic conditions

                           15
Carrier Ethernet Testing Methodologies (2)

• Performance/Scale
  – Verify forwarding performance capability as specified
    by the service
  – Devices and sub-systems must be tested under full
    connection and traffic load
  – Port, Service, Address and tunnel scalability
• Resiliency
  – Ability to monitor network conditions and diagnose
    problems
  – Fail-over performance must be verified



                           16
Current Testing Status

• Service Testing
   – MEF9 and MEF 14 are well defined and understood, provide
     benchmark for testing
• Interoperability
   – Significant challenges with E-OAM/CFM and PBB-TE (PBT)
   – Important events like EANTC testing accelerating development!
• Inter-working
   – Slow progress testing new metro protocols with IP/MPLS core
   – Little to no progress testing inter-working of Fault Management
     (E-OAM/CFM with MPLS-OAM VCCV, MPLS Ping)

                       18
Overview of Interoperability Test Event

• Focusing on end-to-end, multi-vendor
  Carrier Ethernet implementations
• Third event focusing Carrier Ethernet since
  2005
• Two weeks of
  closed-doors
  testing with
  24 vendors,
  70 engineers,
  65+ devices


                       19

                   20
Metro Technology Testing

• MPLS
  – Results in line with expectations into a mature technology
  – Point-to-point and multipoint services successfully evaluated
  – Separation of administrative domains verified
• PBT
  – First public test with nine vendors, based on pre-standard draft
  – Point-to-point services established successfully across all
    devices
  – Interoperability of Connectivity Fault Management (CFM) is in its
    early stages
• T-MPLS
  – First public test with five vendors
  – Point-to-point services successfully established



                                21
Access Technologies Testing

• We tested Ethernet over …
   … PDH over SDH
   … Microwave links
   … 2baseTL (DSL)
• Ethernet Link OAM
   – Huge number of implementations
   – Discovery supported in all cases
   – Dying gasp support growing
• Ethernet Service OAM
   – Support for loopback and
     link trace growing




                                        Link OAM (EFM) Topology

                                   22
Multi-Vendor Provisioning Tests

• Control Plane
  support:
   – MPLS: Built in
   – PBT: External by
     protocol design
   – T-MPLS: No
     explicit definition
• Multi-vendor external
  control plane
  (provisioning, OSS)
  tools required
   – PBT trunks established
     by two provisioning
     solutions



                              23
Summary of Interoperability Status

• Positive and promising start for new
  transport technologies (PBT, T-MPLS)
• CPE devices can be better managed using
  Ethernet OAM
• Reassuring steps into multi-vendor
  provisioning, can be expanded in the future
• Outstanding progress in the third public test
  event at CEWC
