Accedian’s Performance Solution for SLA Based Business Services

Carrier Ethernet & IP  have emerged as the protocols of choice for both current and next-gen telecommunications services.  However, those services are not really a “one-size-fits-all” proposition and  present some very unique challenges in that the range of service characteristics, such as Committed Information Rate (CIR), acceptable packet Loss and Latency can vary greatly from service to service.

Since Business Services are more diverse than mobile backhaul or LAN based Ethernet,( ie: VoIP, interactive video/data, content distribution, email and web services) and have different network performance requirements such as frame loss ratio, latency and jitter, solutions for Business Services need to work within these parameters to deliver the QoS that Business Services customers demand.

Some of the key features and benefits that Business Services customers are looking for include:

Accedian Networks understands Business Services and provides solutions that can efficiently identify and mark these services so that they can be effectively delivered to meet and exceed even the most stringent SLA’s.    Accedian Business Services solutions deliver performance assurance to customers with 6 key differentiators:

1 Complete End-to-End Solutions

ISSUE:
Business Services providers are looking for a wide range of solutions that can address their needs, while delivering the flexibility to evolve their networks.

ACCEDIAN'S APPROACH
Accedian delivers Service Creation and management with a suite of purpose built products that deliver best-in-class performance. Our Performance Assurance solutions deliver:

i. Advanced Loopback testing capabilities
ii. Industry standard Ethernet OAM
iii. Real-time performance monitoring
iv. Service termination, including both UNI Type I and II interfaces

Accedian’s simplified deployment allows for, Zero-touch provisioning and automated Service activation testing which aids in delivering a faster time to revenue.

2 Application Specific Traffic Classification

ISSUE:
Since different services have different networking needs (VoIP requires low latency, low jitter and reasonable packet loss, and Video requires reasonable latency, low jitter and extremely low packet loss), the ability to properly identify applications and handle them accordingly is key.

ACCEDIAN'S APPROACH
Accedian is able to identify each application based on Layer 2, Layer 3 and Layer 4 header information and map the applications to the appropriate class of service. Accedian’s granular traffic classification can even uniquely identify most Layer 4 application protocols.

3 Future-proof, 100% programmable, FPGA based architecture

ISSUE:
Change is an inevitable part of Business Services. Therefore, both services and platforms need to evolve to include new or additional features to address the constantly changing services and network requirements.

ACCEDIAN'S APPROACH
Accedian’s 100% PURE FPGA programmable design de-risks network investment (CAPEX) by providing a graceful and controlled method to upgrade network and service capabilities to address emerging business needs. Furthermore, due to Accedian’s unique FPGA based solutions, latency is never an issue since we make packet forwarding decisions on a nanosecond basis, even before the packet has been fully received.

4 In-service Throughput Testing

ISSUE:
Typical Through put testing techniques, such as RFC 2544, are considered ‘disruptive’ tests and can only be executed when customer services are not running. This means when a customer calls in to say their service is not performing as expected, the service provider needs to take the customer out of service to identify the issue.

ACCEDIAN'S APPROACH
Accedian’s solutions deliver non-disruptive validation of the service, including capacity and throughput by using end-customer traffic as part of the test pattern and generating supplemental test traffic in real-time to ‘fill out’ the idle gaps, thereby testing the customer service performance during normal business hours, without taking the customer out-of-service.

5 Hierarchical Quality of Service

ISSUE:
Traditional, single level, QoS solutions classify and schedule traffic based on the CoS (ie: VoIP), but cannot also schedule based on customer service packages/bundles (ie: Gold, Silver, Bronze). This results in unused/idle bandwidth which cannot be re-used by the customer for lower priority traffic.

ACCEDIAN'S APPROACH
Accedian’s Business Services solutions provide a second level of traffic shaping within a customer’s services bundle to enable sharing of contracted bandwidth (CIR) between various CoS in the Business Services bundle. With Accedian Business Services, customers with unused high priority service bandwidth will be able to use this bandwidth exclusively for their own lower priority classes within the same service bundle, thereby maximizing their purchased bandwidth while preserving the QoS requirements demanded by their Business Services.

6 Lowest Latency/ Jitter Solution

ISSUE:
Many business critical applications require strict latency and jitter requirements. Failure to meet these requirements can violate SLA commitments; but latency and jitter are natural by-products of classic store and forward queuing techniques

ACCEDIAN'S APPROACH
What is needed is to eliminate or minimize the store-and-forward impact on the network. Accedian has developed its Business Services solutions to provide real-time queuing which does not use store-and-forward, but allows control of CIR/CBS per CoS and Strict Priority scheduling to ensure critical traffic is transmitted with minimal or no delay.

Today, service providers are looking for solutions that can address these needs cost effectively while, at the same time, providing them with the flexibility to evolve their networks and Business Service offering to address emerging service requirements.
