IBC On-Line Environment

Objective


The integrated broadband communications (IBC) online environment (IOLE) ultimately consists of telecommunications oriented operating system with special enhancements to meet particular IBC requirements (such as extendibility and dependability).
The IOLE project developed and validated (through prototypes) an architecture, describing the logical structure and the interfaces offered by the online environment, and set of related models. The project was centred on the execution environment for IBC applications. The project defined the architecture for its online environment, and a defined the corresponding interface. This was done in conjunction with an implementation model, methodologies and tools for online software extension, fault tolerance, testing, monitoring and human machine interface (HMI).
The IOLE application model includes a set of rules for organising and structuring an IBC application and the information needed to describe it (for example, documentation, configuration information, online software extension preparatory information). This model must benefit from tight consistency with the online interface design.
The IOLE communication model describes the fundamental communication mechanisms supported by the online interface. This model deeply affects the strategies for online software extension, online testing, fault tolerance and also the IBC application model.
The methodology for online software extension defined by IOLE provides the basis for performing software extensions and the testing and monitoring of the newly introduced software without disturbing the provision of services.
Technical Summary

The IBC on-line environment ultimately consists of a telecom-oriented operating system with special enhancements to meet particular IBC requirements (such as extendibility and dependability).

The IOLE project developed and validated (through prototypes) an architecture, describing the logical structure and the interfaces offered by the on-line environment, and a set of related models. The project was centred on the execution environment for IBC applications. The project defined the architecture for its on-line environment, and defined the corresponding interface. This was done in conjunction with an implementation model, methodologies and tools for on-line software extension, fault tolerance, testing, monitoring and HMI.

The IOLE application model includes a set of rules for organising and structuring an IBC application and the information needed to describe it (for example, documentation, configuration information, on-line software extension preparatory information); this model must benefit from tight consistency with the on-line interface design.

The IOLE communication model describes the fundamental communication mechanisms supported by the on-line interface. This model deeply affects the strategies for on-line software extension, on-line testing, fault tolerance and also the IBC Application Model.

Some of the research items considered by IOLE were:

- techniques for user-transparent tolerance of hardware faults
- guidelines for the design and implementation of computing elements to support the on-line interface
- intra-node interconnection network communication protocol proposal
- non-disruptive multiple-component software extension methodology
- function and data consistency planning algorithms
- minimally disruptive state transfer strategy
- distributed algorithms for the detection of termination of collections of components.

The methodology for on-line software extension defined by IOLE provides the basis for performing software extensions and the testing and monitoring of the newly introduced software without disturbing the provision of services.

The IOLE on-line environment offers three basic tools: on-line software extension, on-line testing and human- machine interface.

The IOLE project cooperated with the other programming infrastructure projects and presented its work in different conferences.
