Converged packet-based access

platforms designed to operate

at the edge of the metro and

wide area network

With customers demanding higher speed

Ethernet services at lower price points,

service providers are faced with the task of

evolving their circuit-switched backbones to

IP/MPLS-based backbones During this

evolution, carriers will have to maintain and

continue to offer services that have been traditionally offered over SONET/SDH, Frame Relay and ATM circuits

This creates a dilemma: How can providers enable these new Ethernet services and applications while maintaining the viability

of current services and infrastructures? With features like Q-in-Q tag stacking, 4,095 VLANS, rate limiting, link aggregation, multiple levels of Quality of Service (QoS), 802.1d bridging, a unique “EtherDACS”

port/VLAN switching mode and Ethernet transport ranging from 10/100 to Gigabit Ethernet, the LoopStar 700 allows service providers to offer robust Ethernet services

to their customers

The end goal for metro Ethernet service

providers is to offer their customers ubiquitous

connectivity One method is to create a

multipoint-to-multipoint Ethernet service which

will connect multiple LANs and behave as if all

of these LANs are part of the same network,

whether they are local or dispersed

geographically The emerging Virtual Private

LAN Service (VPLS) standard offers the

potential to provide this functionality ADC’s

LoopStar 700 product family can separate

customer traffic into VPLS pseudo-wires

according to the different services or

applications required by the customer

VPLS provides several key benefits to carriers

and service providers, including:

vision for Ethernet services is to deliver true

protocol-transparent,

multipoint-to-multipoint connectivity across wide area

networks (WANs) VPLS provides this type of

ubiquitous connectivity service across

multiple metro networks, regardless of

location

all services to appear as if they are on the same Local Area Network (LAN), regardless

of their physical location This removes complexity from the enterprise network and allows carriers to scale their networks faster and easier

of an underlying IP/MPLS infrastructure, which offers tremendous scaling advantages over spanning tree and VLANs In a VPLS-enabled network, provider edge (PE) devices are used to create one or more VPLS domains, which are maintained as individual VPLS instances on the PE box

Ethernet, the most widely deployed LAN technology in the world, as the customer handoff This greatly simplifies the LAN/WAN boundary and allows for rapid and flexible service provisioning

Intelligent Services Management

Every aspect of LoopStar 700 intelligent

services management provides carriers with the

ability to manage, monitor and diagnose both

the multi-service connection to the customer

on one side of the demarcation point and the

connection to the service provider on the other

Managing the Network Interface Device (NID)

The LoopStar 700’s NID functions make it easy

to install, provision and manage anywhere

from a simple point-to-point connection to

thousands of service demarc points, without

the need for truck rolls to provision new

services or diagnose problems Capabilities are

detailed in the individual data sheets

Managing the User Network Interface (UNI)

The LoopStar 700’s UNI functions are designed

to enable the carrier to generate multiple

revenue streams from a set of differentiated

services that are backed by rigorous SLAs

Capabilities include VLAN switching, stacking

and swapping; granular rate-limiting and

policing; layer 2+ traffic classification based on

VLAN ID, VLAN P-bits, ToS bits and DiffServ

Code Points; multiple service queues and

queue servicing mechanisms; and patented

automatic jitter buffer optimization to minimize

delay in circuit emulation applications

Pseudo-Wire Emulation

Using a robust and patented circuit emulation

technique, the LoopStar 700 platform converts

TDM traffic into packet form and feeds it to

the Layer 2 switch for transport over the packet

backbone A LoopStar 700 at the far end converts the traffic back into TDM for delivery The emulated TDM circuit meets the same performance specifications that carriers expect from traditional SONET/SDH transport systems For example, the LoopStar 700 family supports:

• A unique adaptive timing technique with advanced algorithms to meet circuit jitter specifications even in the face of high packet delay variation and packet impairments The LoopStar 700 can also synchronize from an external timing source or incoming link

• An auto-optimizing jitter buffer that intelligently absorbs packet delay variation, recovers from out-of-order packets, and minimizes the effects of lost packets

• Mapping of circuits to standard IP packets that are carried over standard Ethernet frames, with or without VLAN (Virtual Local Area Network) tags

Protected Switching Ring (PSR)

LoopStar 700’s patent-pending Protected Switching Ring (PSR) is a low-cost ring topology that can be built using standard Ethernet technology and methodology—and can recover from multiple types of faults within 50

milliseconds PSR capabilities provide a much needed answer for carriers who want to use Gigabit Ethernet over dark fiber PSR can also

be used to extend backbone rings that use other technologies such as DWDM, SONET/SDH or RPR and allow providers to offer resilient services to smaller locations
