After successful completion of the course, students are able to plan, optimize, design, build and operate a new generation of networks that, at the one hand, differentiates in using rather different implementation technologies that are used for access and traditional networks compared to those used within SDN-Twin networking, and on the other hand, this network generation distinguishes between end-to-end flows being the data traffic clients and the networking part itself. All these flows can generally be considered as a digital twin flow since all network protocols can be regarded as a transmitter-receiver twin connection. Since signal generation is considered as the real-world original, transmission should be defined as real twin and receiving as virtual twin. A duplex connection will be two opposite-direction twin connections. Broadcast one transmt-twin and multiple receiver-twins. In case of anycast at both sides an adequate number of the two twin types.
Hardware: DDRxRAM, NVM, CPU, GPU, DPU, CXL lanes, interne Verbindungsoptik oder Ethernet backplane.
Software: CXL, MVMe, CUDA, RoCE.
• PCIe (peripheral component interconnect express),
• CXL (compute express link),
• NVMe (non-volatile memory express),
• CUDA (compute unified device architecture),
• RoCE (RDMA over converged Ethernet),
• CPU/GPU/DPU chips (universal, paralleling, routing included),
• Memory: DRAM, DDR2... DDR6, persistent, NVM (non-volatile memory).
Software-defined-networking with digital twins is a complete new way of networking for many kinds of networks. Teaching this new method can only be effective when at least all major issues are addressed. There must be a fast and steep learning curve. This new topic is covered in a set of optional lectures for which one can collect additional credits. In the Master and PhD programs, there is not a need to collect so many credits. In fact, this is a complete special topic study embedded in a collection of voluntary lectures. In order that attendees interested to be trained in all aspects of SDN-Twin networks can profit, an appropriate mode of examination will be introduced.
The examination will be performed as special examination events with additional audience in lecture room EI 7 during lecture-free days after and before a semester. In addition, also such events in smaller rooms will be organized on request. Both in WS and SS there are SDN-Twin lectures. On the SDN-Twin homepage, additional information will be available to prepare for the examination questions. In each semester, candidates can take an exam for up to 4 visited lectures with an assigned topic consisting of a written report (about 20 pages), a presentation (20 minutes) and answering questions on the content of the lectures indicated in the exam registration (10 minutes). Each visited optional lecture will be honored by 3 ECTS, so that also all surplus optional lectures will appear as certificate for the special SDN-Twin education. Of course listeners are welcome to attend all examination events.
