Datasheet

Overview

TestCenter Protocols is the protocol test capability of VIAVI TestCenter. Service providers, data center operators and cloud environments use it to validate protocol functionality, performance and scalability. Setup wizards guide configuration, and the tests follow defined methodologies. They range from simple functional checks to large-scale service provider and data center configurations.

Protocol coverage

Routing support covers IPv4 and IPv6 unicast and multicast routing protocols. The 5G xHaul packages emulate 5G fronthaul protocols, including eCPRI, O-RAN O-DU/O-RU and NGFI, as well as IoT protocols. For data center and SDN testing, the portfolio covers SRv6 services and the service-provider SDN protocols BGP-LS, PCEP and segment routing. Switching coverage includes Carrier Ethernet and timing protocols such as IEEE 1588v2 and Synchronous Ethernet.

Access, application layer and benchmarking

Access testing covers IPv4/IPv6 subscriber protocols such as DHCP, PPPoX and L2TP. Application-layer testing includes FTP, HTTP, voice, video and IPTV. Benchmarking packages implement the IETF RFC methodologies for Layer 2-3 switching and IP multicast: RFC 2544, RFC 2889, RFC 3918 and RFC 8239.

Packaging

Each protocol is licensed as a separate base package or test package. Each package has its own datasheet and runs on TestCenter hardware test modules and appliances, or on TestCenter Virtual where supported.
