  Abstract

The increasing complexity of the network traffic and the way service function chains (SFC) were architect make it difficult to readjust an on-going SFC when unusual events occur such as traffic overhead or Denial-of-Service (DoS). Normally, network administrators have to modify the degraded SFC manually by defining a new set of virtual services with new traffic classifiers, then deactivating the current set of virtual services and finally activate the new set. That process often causes dissatisfaction from customers because of prolonged downtime. This paper proposes a novel mechanism that supports dynamic update of SFC(s) using a continuous monitoring technique based on predefined policies which will help reduce the chance of disconnection and improve the effectiveness of fault management. An use case is also discussed to show the feasibility of proposed mechanism.
