Expansion Adaptation of Attack-Aware Controller-Link-Switch Cost Minimization Placement in Software-Defined Networking

Abstract

As a network expands over time, the initial attack recovery and prevention measure may suffer from hiccup where Software-Defined Networking (SDN) controller supply is overwhelmed by traffic demand. The amount of SDN controller increases as demand increases, yet, the recovery planning is lacking behind. As such, network recovery reconstruction is advised as it is impractical to remodel the whole network. Conventional attack-aware placement scheme placed a number of backup controller (BC) dedicated to a controller at node. This will cause the network planning cost to surge drastically over time. Heretofore, centralized placement of a pool of backup controller is rarely observed in SDN field. Thus, we would like to introduce an Attack-Aware Recovery and Expansion controller-link-switch Cost minimization placement in software defined network (ARE_C) with the aim of reducing network planning cost while producing a backup controller pool placement for existing SDN. ARE_C is extended from a prior work, attack-aware recovery controller-switch link cost minimization placement algorithm (ARC) by revolutionizing the technique of selecting and placing backup controller in a SDN. We suggest the employment of BC concentrated as a pool at an unused node. The BC pool is readily used as a replacement or to reduce network traffic load in the event where controller malfunction occur due to attack and failure. Compared to ARC, the ARE_C proved to reduce cost of network planning in BC and link cost while tackling demand issue due to network expansion.
