What are laboratory test solutions?
Because of the criticality of the applications running on today’s networks, it is essential to carry out checks in preproduction environments on new implementations, the deployment of new devices, infrastructure expansions, and so forth, to ensure that network operation will not be compromised once it moves into production.
It is essential to have solutions that test and validate network scalability and device and service performance by means of high-capacity tests that simulate network traffic and oversubscription of applications and that can ultimately take the network and its components to their operating limits.
back to networks and systems
Application areas
Network function virtualization
Thanks to virtualised test environments capable of generating traffic and emulating L2/L7 protocols, dedicated application performance dedicated appliances is evaluated, orchestration/management of geographically distributed functionalities is verified and any new vulnerabilities can be discovered.
Wireless
(mobile/WI-FI)
Test solutions that deliver the realism and high scalability needed to validate the critical elements of wireless technologies and optimise the user experience in mobile environments, congested conditions, interference and even faults, by recreating complex LTE, 3G, WiFi, HetNets scenarios in the laboratory.
Application performance
Evaluation of multiplay-converged services and application-delivery platforms by emulating clients and video, voice and data servers and their associated protocols. It supports advanced client modelling that creates realistic scenarios for measuring quality of experience (QoE).
Insertion of disruptions
This allows users of traffic-generation and protocol-emulation test systems to simulate the WAN network conditions (packet loss, jitter, latency, etc.) to create environments with realistic conditions that can be reproduced in a controlled and stable manner.
Software defined network (SDN)
Use of test tools designed for virtual environments that allow traffic generation and emulation of protocols such as OpenFlow and VXLAN for verification of capacity, scalability and convergence of SDN network infrastructure.
Mobile core network
Test solutions for validating in IMS, LTE environments that allow testing of functionality and capability of systems and equipment by simulating network components such as MGW, softswitches, IP/ISDN PBX’s, HLR/HSS, GW signalling/access, HSS, x -CSCF, AAA and Sigtran elements, etc.
Carrier
ethernet
Evaluates Carrier Ethernet implementations, answering questions related to performance, operation, administration and management (OAM).
Broadband (XDSL, FTTH)
Evaluates access networks and their components, as well as quality of experience (QoE) emulating protocols and devices in xDSL or FTTH Broadband Access environments
Datacenter /
Cloud
Simulates systems, technologies and protocols related to data centres, such as virtualisation, storage, switching fabric, and so forth, as well as application clients, to test for performance and compliance.
High speed ethernet
Validation and certification of the compliance of high-speed devices (40GbE and 100GbE) by generating traffic at line speed for packet forwarding verification and analysis of the physical environment.
Routing /Switching
Traffic generation and routing and switching protocol emulation for functional analyses of scalability and routers and high-capacity switch performance with high speed-ports
Security
Simulation of real user traffic acting as client and server at line speed, sending good traffic along with malicious traffic (DDoS attacks and vulnerabilities to measure performance and protection of security systems).
Objetives
Functional testing
To verify/certify the proper operation of each of the functions supported by the SUT (system under test) or DUT (device under test)
Load tests
To verify the maximum capacity supported by the SUT or DUT in each of its functions using test environments that simulate demanding conditions.
User acceptance
To check whether a service is able to support the business for which it is intended. Each service is tested from the user’s point of view by simulating every possible interaction
Regression testing
To define, by comparison with a baseline, whether configuration changes, topologies, devices and the like affect the service in any way.
Beneficios
Reduction of the number of network incidents.
Characterisation of devices and control of scalability that enables better planning for growth
Reduction of incident resolution-times
Faster time-to-market
Performance optimisation.
Verification of compliance with standards
