Design and development of SDN controllers (published the 08/11/2019)
2020/01/02 - 2020/12/31
The CRAN laboratory has a "network experimentation platform" composed of:
- 8 Cisco IE 3000 switches (implementing the IEEE1588/PTP synchronization protocol)
- 93 microPCs (Raspberry PI type) used for the traffic generation
- 8 PCs equipped with two Ethernet cards (including one PTP-IEEE1588 Meinberg PTP270-PEX card) to observe the traffic (port mirroring)
- 124 category 6 Ethernet cables (variable length) for a total length of 192.5 m.

We have enriched the current platform by purchasing:
- 5 Cisco "Industrial Ethernet 4000" switches implementing the latest amendments of the Ethernet standard (IEEE 802.1AB, AS, ASbt, AQ, CB, Qca, Qaz, Qat, Qav, Qbv, Qch, Qci, Qbu, Qbu, Qcc, Qbp, Qbz), gathered since 2014 under the term "Time-Sensitive Networking" (TSN). TSN aims to provide Ethernet with intrinsic real-time capabilities, allowing to transmit control messages with latency of a few nanoseconds, guaranteeing bounded delivery delays and jitter.
- 5 SDN NETGEAR GSM4352S-100NES switches supporting the Openflow protocol and enabling to program the network control laws (data plan and control plan in the sense of SDN: Software Defined Networking) to be applied to the communication architecture,
- 8 TAP (Terminal Access Point) allowing to capture directly the traffic on the links (in a passive and transparent way, which is not the case with port mirroring). The challenge for the control and the observation is to reduce the measurement latencies and the clock shifts.

Mission :
As part of a team of 5 people (1 Professor, 2 Assistant Professors and 2 PhD students), the researcher will participate in the design and the development of SDN controllers. He will have to implement and evaluate them on the TSN platform described above.
