- Abstract
- The virtualization and softwareization of network functions, controls, and applications are promising as they optimize costs and processes while bringing new value to the network infrastructures. However, the centralized reliability management over the complex softwareized network poses both scalability and latency challenges on the failure recovery process. In this paper, we propose a Network Architecture-aware Reliability Management Schemes (NetAware) to efficiently orchestrate different reliability monitoring mechanisms over SDN network architecture and synchronize the control messages among different controllers and applications. NetAware facilitates many common reliability monitoring factors for the registered applications by analyzing both off-line and on-line network architecture information such as network topologies, virtualization, and protocols. NetAware consists of a High Availability Registration Platform (HARP) and a Topology Aware Reliability (TAR) discovery facilities. A prototype is implemented on Cisco's OpenDayLight (ODL).
