As stated previously, Ethernet over MPLS was originally developed for carriers who wished to offer point-to-point Ethernet services across Layer 3 IP/MPLS backbones This was fundamentally a wide area application providing PoP to PoP Ethernet private lines One of the key drivers for carriers in deploying this application was to offer services to customers such as Internet Service Providers or large enterprises that wanted high bandwidth from point-to-point and wanted to keep their routing separate from that of the carrier

The second phase of Ethernet over MPLS deployments came as carriers looked to scale Carrier Ethernet services that had been deployed using Layer 2 Ethernet switches Layer 2 Ethernet switching suffers from a number of limitations when applied to carrier networks:

Example 1: 6% commission paid for all sales dollars Example 2: 25% commission paid on all gross margin dollars Example 3: $10 commission paid for each unit sold

Protection Ethernet-switched networks depend on the Spanning Tree Protocol for protection This is acceptable in simple topologies, but becomes hard to manage in larger and more complex networks Spanning tree timers have to be increased as the topology grows, in order to prevent stability problems (the default timers impose a maximum diameter of seven hops) Disabling links may also be unacceptable as a protection mechanism in the network core Deploying MPLS in the metro core enables carriers to constrain spanning tree to the edge of the network, enabling networks with larger numbers of nodes to be deployed and to make use of all available core links MPLS also offers protection mechanisms that converge faster than Rapid Spanning Tree Protocol

VLANs 8021Q has a 12-bit VLAN space, allowing 4094 VLANs Since most Ethernet switches are unable to translate VLANs, this creates a fixed limit on the number of VLANs, and hence on the number of services per network By deploying MPLS in the metro core, using PE devices that have per-port VLAN scopes, carriers can constrain the scope of VLAN uniqueness to much smaller domains removing the restriction on the number of services supported Another issue with VLAN switching is that in order to provision a VLAN through the network, multiple switches must be configured, or the provider must run protocols such as GVRP to propagate VLAN knowledge Many PE devices support 8021ad provider bridging (or Q-in-Q ) on their access ports, enabling carriers to assign a unique Provider VLAN to each customer-facing Layer 2 switch port and then to support multiple Customer VLANs within each of those ports Thus, customer VLAN provisioning can be constrained to the PE device MAC address scaling In a Layer 2 switched network, each switch learns the MAC addresses of all active stations on all VLANs that pass through that switch With Ethernet pseudowires PEs do not have to learn MAC addresses, whereas for VPLS MAC address knowledge is constrained to the PE devices that are members of each VPLS instance (hiding MAC addresses from core LSRs) MPLS PE devices also typically support larger numbers of MAC addresses than Layer 2 Ethernet switches This scaling is critical in cases where carriers connect customer switches directly to a Layer 2 service The N-PE devices in H-VPLS will typically learn more MAC addresses than the U-PEs, and for this reason, there has been some investigation of solutions that remove the requirement for the N-PEs to learn customer MAC addresses Use of facilities Layer 2 Ethernet switches are interconnected using Ethernet links If a provider has access to dark fibre (or wavelengths), then Ethernet interconnection is generally the most cost-effective option; however, in some cases, providers may only be able to obtain SONET/SDH connectivity, which is not suitable for interconnecting Ethernet switches unless additional adaptations such as Ethernet over SONET/SDH are deployed MPLS enables providers to use the cheapest available transport to interconnect PE devices because MPLS is link-layer agnostic.

Note: In the example in Figure 5-3, the payment begins with the first dollar or unit of sale So, there is no threshold that must be reached before payments can begin, nor is there a cap or maximum payment either In this illustration, commission earnings are unlimited
