Rules for Thinking About Metro Ethernet

• Metro Ethernet is/can…1. Provide Ethernet

interface to the service provider’s customer

2. Complimentary to SONET and SDH

3. Inclusive of Cisco’s routing platforms (Cisco 2600 to 12000) and optical platforms (ONS-15454)

4. Capable of allowing a provider to offer enhanced services (voice, video)

5. Can create a service offering a provider can make money from

• Metro Ethernet is NOT…6. Necessarily about

Ethernet end-to-end

7. Synonymous with Transparent LAN Services

8. About only Ethernet switching

9. About a cheap service

10. About bandwidth -on-demand (although that’s a component)

Fiber Availability and Ethernet Access


Agenda

Transport Options – Incumbent vs. Dark Fiber

• Transparent LAN-optimized

• Effective for a small number of customers

• Redundancy has to be carefully planned due to Spanning Tree

• Ethernet service over an existing structured fiber plan

• Incumbent architecture

• Larger implementations

• Build-in resiliency scheme (UPSR, BLSR) can eliminate Spanning Tree

Here’s What a Provider Wants to Do…

• Provider wants to offer Ethernet access to customers

• Considering point to point fiber to each customer using Ethernet switching as the backhaul and aggregation

• However…


…And Here’s What a Provider is Stuck With

• …how does that scale to offer service to more customers?

• …fiber plant doesn’t run in straight lines. More fiber required to follow streets, highways, ducts, etc. And…


5


Fiber Plant Ring-based Installation

• To scale access to the customer base, providers will use fiber rings.

• To scale capacity, providers will run many cores in the duct

• To scale bandwidth, providers will use DWDM or CWDM

• To scale efficiency, providers will use SONET/SDH


Metro Network Hierarchy

• SONET/SDH is existing transport

• Discussion w/ SP must include best utilization of existing infrastructure

Comparison of Ring Technologies

SONET/SDH Switched Ethernet using Spanning Tree

DPT/RPR CWDM

• Installed base in service providers• Evolutionary approach for the service providers vs. revolutionary• Best choice for large scale deployments• Best use of fiber infrastructure• Hierarchical bandwidth • Best fiber utilization for dual homing • Next-gen SONET, with VCAT, LCAS, GFP, will help optimize SONET for data• 50 ms convergence

• Low cost solution over dark fiber• Perceived simplicity of Ethernet switching• Fairness, bandwidth, delay/jitter dependant on location on the ring• 10-12 node limit• LAN switch as edge device (no MPLS, Traffic shaping, BGP, etc)• 1-50 seconds convergence (standard 802.1d or 802.1w)

• Shared packet ring scales bandwidth up to 5 Gbps• SONET framing provides insertion point for many providers• Spatial reuse provides good bandwidth utilization• Optimized for Layer 3 (currently)• Large number of nodes (128) per ring• 50 ms convergence

• Guaranteed bandwidth per lambda up to 8 nodes• Logical star over a physical ring• EtherChannel or Layer 3 load balancing for redundancy • 200 millisecond failover• More consistent delay/jitter and better access onto the ring•Still a low-cost Ethernet switch at edge

L2 VPN Multipoint Ethernet Service

• Does it really meet customer demand?

• most enterprise WAN networks are P2P using routers as CPEs

• Some TLS facts from US SP customers:

• Majority of their customers are P2P

• Majority of their customers have only twoMAC addresses facing the SP (i.e. CPE are routers)

• MP2MP customers have an average of 5 sites

What is VPLS?

• A Virtual Private LAN Services (VPLS) is a multipoint Layer 2 VPN that connects two or more customer devices using Ethernet bridging techniques

• VPLS is an ARCHITECTURE defined within IETF Draft-lasserre-vkompella-ppvpn-vpls-02.txt

• A VPLS emulates an Ethernet Switch


13


VPLS…

• Often referred to as a Transparent LAN Service (TLS)

• Service Provider cloud appears to be a switch, with UNI supporting VLAN transparency

• The service provider cloud will switch based on (the enterprise’s) MAC addresses

• Service multiplexing allows single port to provide service to multiple end-points (referred to as “point-to-multipoint)

• EVC identified by the VLAN

• CE-VLAN must be the same as SP-VLAN

• Service analogous to Frame Relay, functionally, it is the same – encourages a router as CE edge device, not a switch (except for remote site)

• ERS allows interworking with FR/ATM (future)

The Ethernet Wire Service (EWS)

• Analogous to a private line in that all data transverses, unaltered across the EVC

• Port-to-Port mapping, no service multiplexing allowed. Therefore all services must exist on one port (All-to-One Bundling)

• Switches or routers can be deployed as CE edge devices
