Wind River Open Virtualization Profile
Adaptive, High Performance Virtualization Built for Scalability, Flexibility, and Openness
|
Real-Time Open Source Virtualization Capacity, scalability, and operational and capital expense challenges, created by the exponential growth of the network, are the top concerns for service providers today. Legacy network elements, built on proprietary, fixed-function appliances, can no longer keep up with the growing need for networks to be more efficient and deliver higher value services while maintaining performance and extreme reliability service level agreements. To help meet these challenges, Wind River® has developed Wind River Open Virtualization Profile, a real-time virtualization solution using open source kernel virtualization machine technology combined with a proven commercial Linux distribution. Open Virtualization Profile is a fully integrated and performance-optimized solution that enables many applications and functions that run dedicated operating systems and hardware to consolidate into one system. Open Virtualization Profile is designed to achieve extremely low-latency, deterministic performance and is applicable for use in next-generation designs where open source software is required. |

USE CASES
Use Cases
Virtualization in the Radio Access Network (RAN)
Mobile operators deploying 4G wireless networks are looking for innovative approaches to reduce the cost of delivering wireless data to their subscribers. The Cloud RAN is a new functional architecture that has the huge potential to significantly drive down these costs. The Cloud RAN Figure 7) separates the base station functionality into a baseband unit (BBU) and a remote radiohead (RRH). The BBU includes the baseband Layer 1 and Base Station (BS) Layer 2 and 3 functionality. The RRH has a low noise amplifier (LNA), intermediate-frequency module and antenna. The interface between the BBU and the RRH is defined by the Common Public Radio Interface (CPRI) and Open Base Station Architecture Initiative (OBSAI) specifications. This architecture reduces deployment costs by enabling base station functionality to be centralized.
Consolidating Best-of-Breed Applications with Multiple
Operating Systems
Situation: An IT department wants the flexibility to choose the best VoIP and security software on the market for an appliance that is also running routing functions.
Solution: Put three workloads in separate virtual machines (VMs), allowing them to run independently on their native operating systems. As a result, IT can make application selections that are relatively independent of other software running on the system.
Application Software Isolation
Situation: Network operators may be concerned about unintended software interactions (e.g., breaches, bugs) between applications.
Solution: Put each application into a dedicated VM, thereby isolating each execution environment and the associated data since all memory spaces are protected in hardware by Intel® VT. Applications can also be assigned to dedicated processor cores in order to increase application isolation.
