    Ethernet VPN

    Product Definition

    A Virtual Private Network (VPN) service is a private network that shares a common platform with other users. This service has been popular over the past few years and in parallel there has been an increasing interest in scalable, end-to-end Ethernet services. Several developments in the area of VPNs have helped to enable Ethernet-based VPNs. Chief among these are two MPLS technologies: Virtual Leased Line (VLL) and Virtual Private LAN Service (VPLS).

    Virtual Leased Line (VLL or E-Line), also known as Ethernet Point-to-Point VPN service, emulates the behavior of a leased line between two points. In the industry, this technology is also referred to as Virtual Private Wire Service (VPWS) or Ethernet over MPLS (EoMPLS). VLLs use the pseudo-wire encapsulation for transporting Ethernet traffic over an MPLS tunnel across an IP/MPLS network.

    Virtual Private LAN Service (VPLS or E-LAN), also known as Ethernet Multipoint-to-Multipoint VPN service, emulates the behavior of a traditional bridge between multiple points. Ethernet Point-to-Multipoint VPN service can be considered as a special case of Ethernet Multipoint-to-Multipoint VPN Service with one site designated as the Hub connected to multiple points.

    Service providers can use these technologies to offer advanced services to their customers such as managed VPN services. Similarly, large enterprises can use these technologies to virtually segment their networks based on business needs, and across geographical boundaries.

    Jumbo FrameThe standard Ethernet VPN service has a Maximum Trans mission Unit (MTU) of 1546 bytes. For customers that require a larger MTU, we offer support for Jumbo frames that increases MTU to 9000 bytes; available only with 1000Mbps ports or greater.

    Port Upgrade

    The standard Ethernet VPN service comes with a 100Mbps port for CIR < 100 Mbps. For customers that require a 1000Mbps port but do not wish to commit to at least 100Mbps CIR, we offer a value added feature to upgrade standard 100Mbps port to a 1000Mbps port.

    VLAN Service

    The standard Ethernet VPN service is provided through a physical port per location. As a value added feature, multiple services can be delivered to a customer at a single location through the same physical port. This feature requires that services be tagged at the location with different VLAN tags so that traffic can be separated by the customer and FPL FiberNet.

    Multicasting

    The standard Ethernet VPN service has limited (1 Mbps) multicasting bandwidth. As a value added feature, multicasting can be supported. This feature may enable customers to multicast up to CIR.Note: This feature is only applicable to Point-to-Multipoint and Multipoint-to-Multipoint VPNs

    Bursting

    Bursting bandwidth is available at best-effort quality up to port speed (100Mbps or 1000Mbps). Since bursting is best-effort, overall service quality may degrade during periods of bursting if critical packets are not able to meet required SLAs (i.e. delay, jitter, loss packets, etc.). To mitigate this effect, customers can prioritize their traffic using Quality of Service feature described in the next section or below.

    Quality of Service

    The standard Ethernet VPN service provides for the highest quality of service for the Committed Information Rate (CIR). However, different types of traffic require different service require ments.

    Note: Standard Product Performance SLAs may not be met for Latency and Packet Delivery if QoS is selected and service experiences congestion.

    As a value added feature, we offer the ability for customers on a VPN service to prioritize their traffic with Quality of Service (QoS) Value Added Feature to get the best Ethernet utilization. This feature allows the customer to prioritize their traffic in a manner that best matches their traf fic service requirements. This should provide best utilization of bandwidth with minimal to no impact to applications within the network.

    The primary function of QoS features is to differentiate traffic types competing for bandwidth in a network. Used properly this feature can help the customer forgo bandwidth upgrades while maintaining performance of mission-critical applications. However, QoS is not a substitute for sufficient bandwidth. Its features are intended to provide deterministic behavior during periods of network congestion. This behavior represents a trade off; usually favoring time sensitive mission critical applications over less time sensitive or less critical applications during congestion.

    Q Is FPL FiberNets Ethernet service completely transparent to all Layer 3 protocols?

    A FPL FiberNet is transparent to all TCP/IP based Layer-3 protocols. Interconnection with certain multicast routing protocols may be required in some instances to control flooding within a Multi-Point service.

    Q Is FPL FiberNets Ethernet service burstable, tiered or usage-based?

    A FPL FiberNet offers bursting service that is priced depending on Committed Information Rate (CIR). Bursting is tiered in that it is allowed, as a value added feature, from CIR up to port speed (100Mbps or 1000Mbps).

    Section 5 Service Delivery

    Q What is FPL FiberNets standard interval for Ethernet service?

    A FPL FiberNets standard interval for Ethernet service is 15-30 business days for On-Net sites, and Off-Net is 60 business days after permits are received. FPL FiberNet defines a site to be On-Net for Ethernet if Equipment and Capacity for desired Ethernet service is available at location where service is being requested; otherwise the site is considered Off-Net.

    Section 6 SLA

    Q Does FPL FiberNet manage or monitor its network?

    A FPL FiberNet monitors the network from our NOC which operates 7x24x365.

    Q What are FPL FiberNets Service Level Agreements (SLA) for its Ethernet service?

    A These are available in MSA in greater detail but a summary version is as follows;

    Latency (RTD) 5ms Metro and 20ms inter-Metro 30ms Inter-StateJitter 5msPacket Delivery 99.95%Network Availability 99.995%Mean Time to Respond (MTTR) 2 hours

    Credits for not meeting any of the above apply but are limited for customer provided power failure, fiber cuts of un-protected services, or fiber cuts of un-diversified entrance and/or risers conduits.
