Periodic Reporting for period 1 - TCN TimeAnalyzer (TimeAnalyzer in real-time networks)
Berichtszeitraum: 2015-02-01 bis 2016-01-31
The goals set up for the project are valid and should remain for the next step, the implementation of the product TCN TimeAnalyzer. TCN studied how to integrate TCN TimeAnalyzer into the SDN architecture with the aim of contributing to the advanced orchestrator algorithms for automated creation and deployment of service chains and dynamic optimization of service quality. Thereby, the 5G network can guarantee the real-time requirements of the most time-sensitive network applications. TCN believes that TCN TimeAnalyzer can be developed into a key component in the orchestration layer in such an architecture.
Within the feasibility study (phase 1 of H2020) TCN has established an unique contact with Ericsson Research 5G Transport Lab, SICS and Acreo (Swedish ICT Research) where they participated closely with surveying Use Cases and requirements. They have also been reviewing this report and are interested to continue the cooperation in a possible phase 2 of the H2020 SME Instruments programme.
Established contact with SICS work in SDN.
In close contact with Acreo, TCN recieved support through coaching activities as offered within H2020.
TCN has organized a number of technical workshops and received valuable inputs from both industry partners (Ericsson, ABB) as well as academic partners (ACREO and SICS). During the workshops, a number of use cases have been presented and investigated. TCN have chosen two concrete use cases in the area of Real-time remote control and operation:
1. Video streaming for public safety applications and
2. Remote controlled excavator.
Even though these two application use cases are of different type, they have very similar requirements on short latency, high bandwidth and time-critical communication.
TCN TimeAnalyzer is an engine that computes the worst case delay bounds for all the high-priority traffic traversing the network. In this framework, TCN TimeAnalyzer will act as an admission control module and scheduler, which determines whether or not the network can provide the requested services based on the current workload and previous commitments. If the network has the capability of guaranteeing all requested communication requirements, it will automatically find the most suitable path through the network and assign priorities for different communication flows.
