Ecrio
Develops communications software for devices, networks and services.
Communications
and networking
Software, wireless systems and the infrastructure behind connected services.
CIR Ventures’ interests span communications, advanced wireless, networking and video over IP. These technologies connect products built by different organisations, with different requirements and operating environments.
A service crosses
several systems.
A device connection is one part of a working service. Traffic must also pass through access and core network functions to reach the application.
This simplified 5G example shows the user traffic path described by 3GPP. Access and session control operate alongside that path; the diagram represents logical functions, rather than a physical installation.
- Device
Creates and receives traffic
- Radio access
Connects the device to the network
- Core user plane
Forwards traffic between access and data networks
- Data service
Provides the application or content
Control and operations
Access and session functions manage registration and connections. Operations teams monitor availability, traffic and faults across the service.
Compatibility needs
a test record.
Standards support establishes a common framework. Deployment still depends on the devices, software and interfaces that have been tested together.
Make the scope clear
- Systems and versions
- Identify the devices, network elements, software releases and configurations included in the evaluation.
- Interfaces and behaviour
- Explain how the product connects, establishes a service and behaves when conditions change. Record dependencies on other suppliers.
- Results and remaining work
- Separate demonstrated compatibility from planned support. State known limits and the integration work still required.
Put performance in context
A result needs its test conditions. Endpoints, traffic profile, load and measurement method determine what a performance claim actually describes.
When measuring delay in one direction, clock synchronisation and measurement uncertainty also matter.
Entering service creates responsibilities.
Customer qualification, installation and ongoing support each require people and resources. A deployment plan should make those responsibilities visible before service begins.
Qualification and installation
Identify who completes acceptance testing, integrates the product and manages changes to the customer’s environment. Include the equipment, access and specialist work the installation requires.
Faults, recovery and support
Explain how faults are isolated across suppliers, who responds and how service is restored. Account for software updates and the support workload after deployment.
Companies in communications
Communications software, television platforms and video infrastructure address different parts of a connected service.
Minerva Networks
Develops software platforms for television and connected video services.
Kasenna
Developed video server software for broadband television. Acquired by Espial in 2008.
