Performance. Increasing bandwidths and real-time requirements such as baseband and multimedia streaming requires near-native performance with NFV.
Security. Intelligent virtualized infrastructure must maintain security and be resistant to malware or viruses that might target network infrastructure.
Manageability. Virtualized, distributed network components must be able to be managed transparently with existing OSS/BSS and provide the ability to perform reconfiguration and still be resilient to a single point of failure.
Wind River recently announced Wind River Open Virtualization. This is a virtualization environment based on Kernel-based Virtual Machine (KVM) that delivers the performance and management capabilities required by communications service providers. Service provider expectations for NFV are ambitious – among them being able to virtualize base stations and radio access network controllers – and to support these kinds of baseband protocols at peak capacity, the system has to have significant real-time properties.
