The shortcomings of traditional Ethernet

• Initially intended for LAN usage
• Lack of OAM (Operations, Administration and
  Maintenance)
• Lack of Performance Monitoring Capabilities
• Lack of SLA Assurance Capabilities
• No clear demarcation points between the Carrier
  and the End customer
• No loop-back capabilities
• Little or no testability of the carrier circuit
• No fault isolation features
• Consequence
• Though Telecommunication Service Providers are
  faced with overwhelming customer demand for
  Ethernet Services, theyre confronted with the
  operational shortcomings of Ethernet which was
  not initially designed for Carrier Networks.
• The CAPEX savings of Ethernet are quickly
  washed-out by increased OPEX

Accedians solutions Raison dêtre

• Despite customer demand and Competitive Pressure,
  certain Carriers hold-back the conversion rate of
  T1-Frame-Relay customers to Ethernet Private
  Line, because of operational shortcomings.
• The Accedian EtherNID is seen as an ENABLER and
  ACCELERATOR for the deployment of new revenue
  generating Ethernet Services (VOIP, E-Line,
  E-LAN, etc.).

• Ethernet media is often extended for substantial
  lengths between the Access Point and the customer

• Loss of all OAM ability as soon as coming out of
  the transport network.
• No clear demarcation point between the carrier

Test set interaction

• EtherNID reacts to in-band loop-back commands of
  industry-popular Ethernet Test Sets (such as
  Sunset MTT, FST-2802, T-BERD-8000, QT-600 and
  others).
• Provides for testing in Loopback mode vs.
  Head-to-Head (allowing for single-ended testing)

  or pass-through.
• Allows controlling the quantity of VLANs that the
  end-customer can use.
• Allows billing the customer on a per-VLAN basis.
• Allows BPDU (Spanning Tree) filtering.
• Supports .1Q in .1Q
• Supports oversized packets up to 1800 bytes on
  100Mbps (9600 on GigE).
• Can complement or replace the use of a VLAN-aware
  edge switch.
• Maintains per-flow statistics, all remotely
  available via SNMP.
• Ideal for delivery and validation of prioritized
  VLAN service delivery.
• Designed to comply with MEF service delivery
  model.
