Exploiting External Event Detectors to Anticipate Resource Requirements
for the Elastic Adaptation of SDN/NFV Systems
draft-pedro-nmrg-anticipated-adaptation-00
Abstract
The adoption of SDN/NFV technologies by current computer and network
system infrastructures is constantly increasing, becoming essential
for the the particular case of edge/branch network systems. The
systems supported by these infrastructures require to be adapted to
environment changes within a short period of time. Thus, the
complexity of new systems and the speed at which management and
control operations must be performed go beyond human limits. Thus,
management systems must be automated. However, in several situations
current automation techniques are not enough to respond to
requirement changes. Here we propose to anticipate changes in the
operation environments of SDN/NFV systems in response to external
events and reflect it in the anticipation of the amount of resources
required by those systems for their ulterior adaptaion. The final
objective is to avoid service degradation or disruption while keeping
close-to-optimum resource allocation to reduce monetary and operative
cost as much as possible. Here we discuss how to achieve such
capabilities by the integration of the Autonomic Resource Control
Architecture (ARCA) to the management and operation (MANO) of NFV
systems. We showcase it by building a multi-domain SDN/NFV
infrastructure based on OpenStack and deploying ARCA to adapt a
virtual system based on the edge/branch network concept to the
operational conditions of an emergency support service, which is
rarely used but that cannot leave any user unattended.
