Service Demarcation

Ethernet services offer bandwidth and cost efficiency

compared to the legacy services they replace, but vendor-

specific implementations often prevent streamlined operations,

administration and maintenance (OAM), driving up OpEx and

placing significant demands on support and operations staff.

Accedian Networks hardware-based, high-performance

EtherNID™ and MetroNID™ packet assurance demarcation

units help operators regain control of their Ethernet services,

increasing the value of every packet flowing through their

networks. Installed as a transparent, in-line service demarc at

customer premises, cell-sites, carrier hand-off points, hubs,

aggregation nodes, COs and mobile switching centers,

EtherNID and MetroNID units define the boundaries of your

network and services without impacting customer traffic.

With a network clearly demarcated and defined, service

providers can establish end-to-end, standards based OAM

regardless of network technology and topology.

Layer 1-4 Loopback Testing

Loopback testing allows service providers to accelerate the

diagnosis and repair of network & QoS issues - without a far-

end test set, truck roll, or waiting for maintenance windows.

Reduce OpEx and CapEx – with less repair time and test sets

in the field.

ESAP enables the most advanced Layer 1-4 loopback testing

available in EtherNID & MetroNID units, permitting remote

QoS testing of Ethernet, IP / MPLS and triple-play services.

Loopbacks can be established by VLAN, source or destination

address, TCP/UDP port, service level, or any combination,

and can be controlled by industry-standard Y.1731 in-band

commands and most 3rd-party test sets.

In-Service Throughput &

Automated RFC-2544 Test Suite

Advanced throughput and RFC-2544 test capabilities allow

service providers to perform fully automated and documented

turn-up tests, then monitor committed and excess throughput in-

service without disrupting customer traffic.

With seamless in-line, in-service testing, there’s no waiting for

maintenance windows to validate and troubleshoot Ethernet

services. It’s only throughput measurement technique available

that tests services under real-world traffic conditions – providing

a true picture of the customer’s QoS experience, and permitting

throughput monitoring for SLA validation.

Using a unique, patent-pending approach, EtherNID™ and

MetroNID™ units use actual customer traffic as part of the overall

test pattern to validate committed throughput, burst performance,

delay, jitter and frame loss. Tests can be unidirectional or

bidirectional with independent throughput tests in each direction.

Performance Monitoring

Map out the Health of your Network™ and monitor critical

SLA parameters including with Accedian Networks’ PAA™

Performance Assurance Agent.

A key part of Accedian Networks SLA-Meter™, The PAA

generates a sparse but continuous stream of time-stamped

Y.1731 test packets between EtherNID and MetroNID packet

assurance demarcation units, which use a patent-pending in-

band synchronization technique to provide one-way end-to-

end delay and jitter measurements to microsecond resolution

– no GPS timing source required *.

The PAA also measures frame-loss and monitors service

availability in point-to-point, point-to-multipoint, mesh network

topologies and for multicast services – each EtherNID or

MetroNID unit can create up to 100 test streams to other

units, each with specified flow characteristics.

PAA packets are tagged with specified customer / provider

VLAN ID, service level and bandwidth class to precisely

capture the behaviour of multiple SLA flows in real-time.

The fully-automated RFC-2544 Test Suite simplifies

performance assurance with straightforward traffic stream

setup, user-defined test parameters and thresholds, and

comprehensive results reporting – a complete turn-up test and

service baseline solution integrated into the service endpoints.

SLA Creation & Assurance

SLA Creation

Accedian Networks’ ESAP™ Ethernet Service Assurance

Platform not only keeps services up and running – it helps to

create them just as easily. Drive new revenue by deploying

end-to-end Ethernet transparent LAN services with guaranteed

performance and availability over any network – without

disturbing your switches or your customers.

Ideal for operators with mixed-vendor, multi-technology

networks, EVC service mapping transparently creates Ethernet

LAN services and avoids interoperability issues that result in

provisioning delays and costly network upgrades.

Map services with advanced bandwidth policies, enforce them

with per-flow traffic control and aggregate multiple customers

directly at the demarcation point. Zero-latency traffic shaping

functionality accelerates access links and optimizes QoS.

Traffic filtering protects VLANs and blocks unwanted traffic

from flooding your network, while bandwidth policing eases

congestion and protects core performance.

With the Fast-Thru™ hardware architecture, EtherNID packet

assurance demarcation units maintain EVCs at GbE wire

speed without adding delay or jitter to critical, real-time traffic.

Easily configured remotely, building EVCs is as simple as

installing EtherNID units at the demarc-points and provisioning

services from the web.

SLA-Meter™ Service Assurance

Accedian Networks SLA-Meter™ combines three advanced

ESAP test functions into a complete in-service SLA assessment

and validation tool. The PAA Performance Assurance Agent

provides one-way jitter and delay measurement with an

industry-leading microsecond resolution, while advanced per-

SLA flow traffic statistics – stored directly on-board EtherNID

and MetroNID demarcation units – provide usage information for

trending and troubleshooting.

Industry unique in-service throughput testing validates SLA-

specified committed and excess bandwidth profiles and burst

Service Mapping

Drive new revenue by deploying end-to-end Ethernet

transparent LAN services with guaranteed performance and

availability over any network – without disturbing your

switches or your customers – with ESAP’s Ethernet service

mapping for EtherNID™ & MetroNID™ demarcation units.

Service mapping allows providers to quickly create Ethernet

Virtual Circuits (EVCs) for E-Line, E-LAN, and E-Tree

services over mixed-vendor, multi-carrier and multi-

technology networks, regardless of the access platform or

network topology servicing a particular customer or cell-site.

Services can be mapped with advanced bandwidth policies

that establish committed and excess throughput and burst

rates (CIR, EIR, EBS, CBS), as well as defined Ethernet & IP

service priorities. Mapping is performed by classifying traffic

based on a rich frame-characteristic filter set, then selectively

pushing VLAN tags onto the appropriate frames as they pass

through the demarc unit. When mapped frames arrive at the

far-end destination, the corresponding EtherNID or MetroNID

unit pops off the VLAN tag and delivers the frame to the

customer site exactly as it was transmitted.

The EVC service mapping feature supports Q-in-Q

encapsulation, ensuring complete Layer 1, 2, 2.5 and 3

transparency over any network or combination of networks.

Integrated bandwidth policing protects core network

performance and ensures that EVCs live up to their SLA

guarantees.

With the advanced packet processing capabilities of the Fast-

Thru™ architecture, EtherNID and MetroNID units perform

service mapping in real-time without adding delay or jitter to

real-time and QoS sensitive traffic.

Use ESAP’s service creation functionality to provision Ethernet services

over any network – without replacing or configuring network elements.

Optimize & assure service performance with hardware-based traffic

conditioning & multi-port aggregation directly at the demarcation point.

Hardware-based service mapping adds no jitter or

Traffic Conditioning

Once a service is created, ESAP’s advanced networking

functionality helps to assure service QoS by conditioning

traffic with hardware-based filtering, rate-limiting and shaping

directly at the service demarcation point.

With traffic conditioning often more capable than features

offered by most switches or routers, EtherNID and MetroNID

units offer a uniform, carrier-grade solution to controlling end-

to-end service QoS over converged networks – even in

leased networks where providers doesn’t own the local

access equipment.

Zero-Latency Traffic Shaping

Accedian Networks offers the highest performance traffic

shaping available, with fully hardware-based packet

processing that passes high-priority, real-time traffic through

the Fast-Thru™ passing lane without adding jitter or latency.

Lower priority traffic is buffered in ultra-fast queues, then

forwarded in priority sequence when bandwidth is available.

Bandwidth Policing

EtherNID™ and MetroNID™ packet assurance

demarcation units support intelligent bandwidth policing on

up to 60 flows in both upstream and downstream

directions. Also known as rate limiting or traffic regulation,

ESAP’s bandwidth policing functionality assures the QoS of

real-time applications such as VoIP, video, and

transactional services by establishing committed

throughput and burst profiles per VLAN, source or

destination address and service level.

Policing helps to preserve the performance of metro and

transport networks – throttling customer traffic at the edge

reduces traffic congestion and network element processing

overhead. It also allows service providers to offer

bandwidth on demand when requested by customers or

required for new service provisioning – without

reconfiguring or replacing network elements.

Performed at full wire-speed by the Fast-Thru™ hardware-

based architecture and packet processing engine,

EtherNID and MetroNID units perform bandwidth policing

without added jitter or delay – providing carrier-grade

switch functionality at a fraction of the cost.

When enabled on MetroNID packet assurance demarcation

devices, Zero-Latency Traffic Shaping allows providers to

performance business access and wireless backhaul

applications – independent of access platforms and

customer switches, and for a fraction of the cost.

Packets are categorized then passed or queued at wire-

speed as they flow through MetroNID units. Highly granular

classification criteria include destination and source address,

TCP or UDP port, VLAN, service level and bandwidth class.
