MCS Thesis Examination - Distributed Provisioning of 5G Service Requests

You are invited to attend the Master of Computer Science thesis examination of Ying Rao.

Abstract

Service function chain (SFC) plays a prominent role in realizing 5G slicing and next-generation network. Supported by the emerging techniques such as Software-Defined Networking (SDN) and Network Function Virtualization (NFV), network operator can freely define and configure a variety of complex network services or SFCs based on business needs, policies, and quality of service (QoS) requirements.

Additionally, 5G networks are expected to be highly dynamic, constantly upgrading and scaling, in which case a plug-and-play mechanism is needed to avoid high operational and management costs, for which the flexible and scalable distributed system is well suited.

We investigate the distributed SFC provisioning problem and propose a fully distributed algorithm that runs in real-time dynamic network aiming at searching and reserving the best-fit resources for each SFC request with manageable message costs.

We conducted a series of experiments on OMNET++ that simulate different dynamic traffics running on a distributed network, and then compare its performance with a classical centralized resource constraint shortest path (RCSP) algorithm, the results show that our algorithm obtains a similar performance to the centralized RCSP in terms of throughput and acceptance rate.
