Routing for open source TSN (Time Sensitive Networks)
- Title : Routing for open source TSN (Time Sensitive Networks)
- Location : Lille / Paris / Munich / Télétravail
- Type : full-time
- Function : Developer
- Duration : Trainee (3-6 months) / Alternance / Employment
- Reference : Offer-2022-TSN-Routing
Description
Nexedi is participating in an industrial automation R&D project whose goal is to make time sensitive networking Open-source with Linux and with a software approach. Usually, industrial automation uses specific hardware linked to proprietary protocols. In contrast, our project aims to offer maximum interoperability and ease of maintenance while maintaining performance. For this purpose we deploy on generic hardware (e.g. Lime2 Olimex) a PREEMPT_RT real-time Linux kernel with optimised configuration and software for TSN (CPU isolation, IRQ assignments, XDP etc...). Rather than using layer 2 network protocols, we will use unicast and multicast routing whose metrics will be adapted to TSN constraints (latency minimisation, congestion distribution, etc.). More specifically, it is planned to use an extension of the babel routing protocol (which we already use for our international cloud network) with the right metrics, and multicast management (Protocol Independent Multicast).
We are looking for developers interested in the following topics:
- Networking, especially routing (unicast and multicast) and all the algorithms that go with it
- Development for and under Linux
- Linux kernel, more precisely the implementation of the network layers of the Linux kernel
- Real-time systems
We are looking for a candidate with experience in C development, a mastery of Linux and an affinity with Open Source / free software
Responsibilities
- help develop an extension of the babel routing protocol for TSN and multicast
- test and verify the performance of the protocol with a virtual network (linux network namespaces)
- help integrate the babel extension into our software and deployment system
Opportunities
- C and python development
- contribution to complex free and open source software solutions
- understand PREEMPT_RT, the kernel network implementation, and learn about routing in detail (IGP routing)
- work with real time systems
