Carrier Ethernet (CE) Service Assurance involves multiple considerations from Service Design, Service Activation, Monitoring, to Diagnostics.
Needless to say, a better designed network would help reduce issues in the field. Validating the network architecture for the Service design and deployment involves verifying interoperability of the equipment used, benchmarking scalability, to benchmarking performance for varying real time traffic conditions to optimizing equipment configurations. All these activities have to be accomplished while realizing the highest possible ROI from the infrastructure investments.
When Carrier Ethernet Services are being deployed, often Service Providers rely on either RFC 2544 or ITU-T Y.1564 tests to check network integrity before service turn-up. However, experience shows that there are a number of other problems that could potentially lie undetected until customers start using the network. Configuration mismatches and equipment interoperability issues can result in a number of problems relating to VLANs, CoS, burst handling, security, etc.
After Service roll-out, it is important to continuously monitor the network and pro-actively resolve issues where possible, or quickly resolve the issues when reported by a customer.
The cost and effort of truck rolls for resolution of these issues tend to be high. The resulting decline in customer loyalty due to service disruptions is obvious.
Veryx SAMTEST provides a comprehensive combination of tests that cover ITU-T Y.1564, MEF CE 2.0, ITU-T Y.1731 together with other proprietary tests for quick and thorough verification of circuits before turn-up. Service Providers can be confident of the integrity of their networks with SAMTEST.
SAMTEST provides the efficiency and capability required by Service Providers to effectively roll-out and manage their Carrier Ethernet network services such as Cloud Services, Business Services and Mobile Backhaul. SAMTEST also enables the Service Provider to benchmark specific sections of Access, Metro and Core networks and expedites end-to-end troubleshooting.
Veryx SAMTEST framework aids network engineers in reducing the time taken to verify services, and supports easy configuration, CLI/ GUI-based access, easy debugging and detailed reporting. Its unique design results in minimal time for set-up and efficient use of time and resources.
Veryx SAMTEST receives Frost & Sullivan Best Practices Award for 2014 Global Carrier Ethernet Testing Customer Value Leadership.
Veryx SAMTEST facilitates:
Service Design Testing: Veryx SAMTEST provides complete test coverage for MEF CE 2.0 to ensure the compliance of new services being designed to MEF CE 2.0 specifications.
Automated Service Activation Testing: Veryx SAMTEST provides automated service turn-up testing and generates birth certificate reports based on pre-built, standards-based test scenarios covering 802.1 ag, Y.1731, RFC 2544, Y.1564 and CE 2.0.
Troubleshooting: Veryx SAMTEST quickly isolates issues related to connectivity, SLA and MEF attributes. SAMTEST comes with pre-built test scenarios specifically designed to facilitate diagnostics.
Monitoring: Veryx SAMTEST provides comprehensive standards aligned Carrier Ethernet service performance monitoring for Ethernet services. It performs monitoring using in-band Y.1731 frames and is completely aligned with MEF 10.2 and MEF 35.
How It Works
The Veryx SAMTEST Service Assurance Solution consists of a central controller and distributed probes:
- SAMTEST Controller is a centralized controller software that co-ordinates with Veryx Test Probes to initiate tests gather statistics and generate reports. SAMTEST Framework executes on the SAMTEST Controller hardware and comes an intuitive GUI that can be accessed via any browser.
- Veryx SAMTEST Probes can generate Ethernet traffic of up to 1G to enable active testing of Service Attributes and SLAs as initiated by the SAMTEST Controller. The traffic generated by SAMTEST probes can be received at the other end by a peer SAMTEST probe, or looped back by a peer access device, to perform the required measurements.
SAMTEST solutions can also be used in the lab during the Service design phase.
The powerful features which make SAMTEST a compelling tool that Service Providers can rely on to speed-up their testing are:
|One Touch Execution||
|Test Customization||SAMTEST tests are developed using industry standard TCL scripts.||Well-defined APIs and source files provide the flexibility to add new tests and customize or modify pre-built test cases for specific requirements.|
|Centralized Control||SAMTEST Framework executes on the centralized controller hardware and can be accessed via web.||Fault isolation can be carried out centrally and field technicians can be effectively used to resolve problems, if any.|
|Flexible Reporting||The intuitive test reports can be easily sliced and diced for various parameters and can be shared with the customers as well as partners.||SAMTEST reports address the needs of a broad audience from technical to executive levels to provide comprehensive insights into SLA performance at various levels.|
|Customer Reports||The customer portal enables ‘per customer’ based reporting which can directly be shared with the customer.||The customer portal can significantly contribute towards increasing customer loyalty.|
|Pre-built Service Activation Tests||The pre-built tests verify Connectivity, Bandwidth Profile, VLAN Preservation, CoS Preservation, Service Performance, Service OAM Handling and Bundling.||These pre-built tests executing in an automated manner substantially reduces Service Activation time.|
|Pre-built Intelligence for Diagnostics||SAMTEST’s powerful debugging features with built-in intelligence to execute various combinations of tests to isolate failure(s) along with multi-level test reports/logs ensure that fault isolation and debugging is efficient and fast.||With this, diagnostics can be carried out using less skilled resources, thereby facilitating efficient deployment of highly skilled resources.|
