  • Stanislav Lange
  • Thomas Zinner
The hierarchical token bucket (HTB) algorithm allows to specify per-flow bitrate guarantees and enables excess bandwidth sharing between flows of the same class. Additionally, it provides capabilities to prioritize the traffic of specific flows, potentially considering their delay demands.

Network operators cannot change their footprint to upgrade the entire network to support SDN from scratch. Hence, network operators adapted the original SDN concept into a hybrid SDN approach to have a pragmatic, evolutionary, and economically viable solution.

Scalable Physical Layer Security Components for Microservice-Based Optical SDN Controllers

  • Natalino, Carlos

  • Vilalta, Ricard
  • Monti, Paolo
  • Munoz, Raul
  • Furdek, Marija
We propose and demonstrate a set of microservice-based security components able to perform physical layer security assessment and mitigation in optical networks. Results illustrate the scalability of the attack detection mechanism and the agility in mitigating attacks.
