Network Functions Virtualization (NFV) is transforming the telecom industry by changing the way networks are built and operated. End-to-end Network Services (NS) like Evolved Packet Core (EPC) and IP Multimedia Subsystem (IMS), or elementary functions like edge routers and firewalls, are being delivered as software modules and instantiated in virtualized and cloud environments backed by high-volume commodity servers. This delivery model replaces the traditional approach of using fixedfunction, proprietary and expensive hardware.
A determining factor for NFV adoption is performance. Virtualized Network Functions (VNFs) running on standard multicore servers should perform at least as efficient as their legacy equivalents.
In a carrier network this requirement becomes even stronger to meet critical targets such as low latency, high throughput and deterministic behavior (low jitter), that ultimately guarantee exceptional quality of experience (QoE) for the end customer.
Intracom Telecom's NFV Accelerator is a platform that boosts the performance and energy efficiency of virtualized Network functions running on commercial of the shelf x86 servers to carrier grade levels.
Intracom Telecom's NFV Accelerator optimizes the execution of virtualized Network Services on managed Data Centers, improving performance, energy efficiency and infrastructure utilization as follows:
The NFV Accelerator platform interacts with the following components of the NFV stack to monitor important metrics and communicate its decisions:
The platform can manage and monitor VNFs implemented as:
The latter category includes user-level Virtual Switches which the accelerator handles as a special, high-priority class of VNFs that also need careful resource allocation.
The operation of the accelerator is summarized in high-level steps, performed by the following modules:
From the administrator's perspective, the NFV Accelerator Platform provides an intuitive and easy-to-use Graphical User Interface (GUI) to drive optimizations.
A typical workflow follows the steps below:
