SD-WAN Conformance (TEC MTCTE ER TEC30072603)

Software-Defined Wide Area Network (SD-WAN) is a virtualized networking architecture that enables optimization of connectivity from branches to HQ, data-center and cloud connectivity, in a well-managed, scalable and secure manner. Its architecture defines an overlay network over underlay transport links using a mix Multiprotocol Label Switching (MPLS), broadband internet, LTE, and 5G.

However, deployment of SD-WAN introduces several technical, operational, and security hurdles that organizations must navigate. Thus, the need for comprehensive test suites that verify SD-WAN routers and controllers for various functionalities and use cases. Veryx ATTEST SDWAN Test Suite is an automated test execution solution for quick and easy verification of SDWAN functionality in compliance with TEC30072603. Veryx ATTEST SDWAN contains separate test suites for SDWAN router and controller.

ATTEST SDWAN router suite contains tests for Path monitoring and failover, Dynamic Path Selection, Overlay Path Resiliency, Load Balancing, Traffic Shaping and QoS, Traffic Encryption, Local Traffic Security, Application-Aware Routing, Cloud connectivity etc.

ATTEST SDWAN Controller suite contains tests for Policy Management, Real-Time Network Analytics & Monitoring, Traffic Engineering & Path Steering, Telemetry Performance Optimization, Zero Touch Provisioning (ZTP) etc.

OEMs, as well as Indian Accredited Labs designated by TEC, could utilize these ready tests for easy verification.

IP Conformance (TEC - MTCTE ER V2 Annexure P1-P11)

ATTEST TEC Bundle is used to verify for conformance to Mandatory Testing and Certification of Telecom Equipment (MTCTE) Essential Requirement – Version 2 Annexure P1-P11,TEC/SD/DD/TCP-222/2.9/August2021, as per Telecommunication Engineering Center, DOT, India.

Equipment vendors selling in India, as well as Indian Accredited Labs designated by TEC, could utilise these ready tests for quick verification of conformance to Essential Requirements such as IPv4, IPv6, TCP, UDP, NAT, SNMP, RTCP, RTP and SIP.

Time Synchronization Testing

In today’s network-connected world, precise clock synchronization has become essential for many applications and services such as mobile, transportation and industrial networks.

Network switches and other devices that include IEEE 1588v2 precise time protocol (PTP) support, have the ability to timestamp packets at the hardware level as they ingress and egress network ports. Further, using the clock type hierarchy in a PTP network essentially removes or compensates for jitter effects and internal delays created in Ethernet switches and maintains time synchronization precision to at least the sub-microsecond level.

Veryx ATTEST PTP Conformance Test Suite deliver equipment manufacturers a ready-made and automated solution for verification of PTP implementation in their Ethernet devices, deployable in automation and control systems, measurement systems and power distribution systems.

ATTEST PTP performs automated conformance testing of network devices for Ordinary Clock, Boundary Clock and Transparent Clock functionality.

CERN, the European Organization for Nuclear Research, is one of the world’s largest and most respected centres for scientific research, and is making major contributions in timing and synchronization area. CERN’s White Rabbit Compliance Tests are based on Veryx ATTEST test suites. For more information visit CERN’s Open Hardware Repository (OHR) project for White Rabbit Compliance Tests.

Switch and Router Testing

Network switches and routers are present practically in any LAN or WAN network today and are being widely deployed in all forms of connectivity, whether wired or wire-less:

Telcos and ISPs deploy core, edge and access switches using IP, MPLS and Carrier Ethernet technologies across the WAN
Enterprises use Ethernet switches for LAN connectivity within the facility or campus and routers for connecting to external networks.
