Performance Testing for IP Services and Systems

Introducing new applications (VoIP, Database) or adding new infrastructure technologies (WAN acceleration optimization), into a IP Network brings new risk such as

• How will this application or change perform on my network
• How will it affect network traffic and the performance of my existing applications

Network Performance testing is often either omitted or is performed as an afterthought with no plan. When a new service is deployed IT departments are often unprepared for the performance problems that they encounter, and then are left scrambling to scale to meet the increased demand.
Performance testing reduces the risk by allowing you to run realistic and "worst-case" testing in a controlled way. Traffic Generation and Network Simulation are two tools that help reduce the cost of new product development and the risk of deploying new technologies and networked applications.
The benefit of Performance Testing are

• Recognize network problems before your customers do!
• Keep your development projects on time!
• Test your development projects and then monitoring your systems for errors.

Network Traffic Generation

Network Load Testing allows you to simulate many network users, and highlight weak points in the systems architecture or design. With the every-increasing complexity of software and hardware, load testing may be the only practical way to highlight software or hardware deficiencies. Stress and Load testing products focus on either network or software performance and may need to be integrated with other test tools such as network analyzers or application analyzers.

Candela LANforge Fire
LANforge Fire is perfect for Stress and Load Testing of networks and devices. LANforge FIRE is a multi-protocol traffic generation tool that can be used to test any network from DSL, wireless access, last mile solutions to large-scale backbone networks. LANforge FIRE can generate TCP/IP (Ethernet), UDP/IP (VoIP) as will as user defined payloads.

Shenick diversifEye Converged IP Network Test System
Next generation IP video, voice, data and security applications demand an uncompromising focus on individual customer quality of experience (QoE) as the key to profitable services. Shenick diversifEye delivers real world proof of concept, demonstration & testing of triple play environments.  Proof of Concept means getting as close as possible to actual deployments with a mix of many individual clients and a mix of several application types, using DHCP / PPPoE per residential gateway (per household) as necessary.

IQ-Service: Contact Center Load Testing
Whether you're deploying a new contact center, implementing CTI, installing an IVR, or modifying existing application software, you need to be absolutely certain that these solutions will perform as you expect - before you go "live."

Network Emulation

Network emulation allows you to capture the existing properties of your current network and/or a planned network change so that you can assess the performance, predict the impact of a network change or the addition of a new application. You can then optimize its performance before deploying it on the network.

Candela LANforge ICE
LANforge ICE can emulate network impairments simulating wireless, satellite and WAN connections such as T1, DS3, OC-3, OC-12, GigE, DSL, Satellite, Dial-Up by setting jitter, latency, packet-reordering, packet-duplication, throughput, and packet degradation

Network Analyzer

Packet Layer Analysis will allow you to understand and troubleshoot what is happening on the network
Network Instruments Observer
