Spirent successfully automates and integrates with TeleTOS framework
to improve test efficiency for scaled NFV deployments

BEIJING–(BUSINESS WIRE)–Spirent Communications plc (LSE:SPT) announced today that it assisted
China Telecom Beijing Research Institute to complete the world’s first
successful carrier-class virtual broadband remote access server (vBRAS)
three-tier decoupling test, marking a significant breakthrough in China
Telecom’s CTNet2025 Network Restructuring. The three-tier project
successfully decoupled VNF elements, the virtualization layer and the
hardware layer, which is the key to large-scale NFV deployments. Only
with decoupling of the three tiers, it is possible to create realistic
network function virtualization and to eliminate soft silos to
accelerate the development of a new industrial eco-system, which is
China Telecom’s primary goal for promoting its CTNet2025 initiative.

At present, three-tier decoupling faces great challenges, including how
to orchestrate components of different levels from different vendors,
how to test across different virtualization platforms, and how to
introduce new testing methodologies for three-tier decoupling. The
capability to test across various platforms is critical in understanding
the benchmark performance matrix of virtual network elements on each
platform, allowing for accurate infrastructure capacity planning and
deployment of future services.

For the test, Spirent provided a suite of test solutions including:
Spirent iTest automated test case execution engine; Spirent TestCenter
performance testing emulation; and CloudStress, a synthetic workload
generator. All these solutions were seamlessly integrated with the
TeleTOS framework, an automated test orchestration system, developed
in-house by China Telecom, that greatly improves test efficiency while
allowing for quick turn-up and operation of new services. It also
enables achievement of a DevOps model for virtual network services and
integration of service development, testing, and operations.

“As a key technology in the process of network restructuring, NFV faces
many challenges in deploying applications at scale in the existing
networks, and the three-tier decoupling is one of the greatest
challenges. Before the vBRAS three-tier decoupling, only hardware and
software decoupling or two-tier decoupling was possible,” says Dr. Zhu
Xuetian, Director, Network Technology Research Department of the China
Telecom Beijing Research Institute. “Today, we are able to achieve
three-tier decoupling in a very short time-period due to unrelenting
dedication and continuous collaboration from Spirent. We have also
developed the TeleTOS automated test orchestration system in-house and
integrated it with Spirent’s innovative test solutions thereby greatly
reducing the time needed for testing and accelerating our time to value.”

“The complete end-to-end Spirent NFV solutions provide carriers with the
necessary tools to assess various virtual network elements including NFV
Infrastructure, VNF and MANO. In addition, Spirent has made many
contributions in NFV testing methodologies, allowing China Telecom to
ensure its high Quality of Service in virtualized operating networks, to
turn-up and operate new services in an accelerated and effective way,”
says Tan Hao, VP of Sales in Greater China and East Asia.

The carrier-grade, virtualization network emulation and verification
platform developed by this team, covers traditional test cases of vBRAS
and includes new test cases for NFV infrastructure benchmarking,
performance evaluation, noisy neighbor scenarios, stability and life
cycle management. The decoupling test has provided reliable technical
evidence for large-scale carrier deployments of VNF. It has also created
a solid foundation and has explored new test concepts and test
methodologies for future three-tier decoupling tests on VNF network
elements such as vEPC, vFirewall and vCPE, representing a solid leap
forward on the road for network restructuring for China Telecom.
