What is Network Function Virtualization (NFV) – COMARCH

Summary

This video highlights the challenges and solutions for controlling autonomous vehicles over traditional networks. Autonomous cars require low-latency communication, but traditional network structures often cause delays, especially during congestion. Network Function Virtualization (NFV) allows for dynamic, priority-based routing, reducing latency by hosting critical applications closer to users. Comarch OSS provides intelligent network management, automating prioritization and virtual machine allocation, ensuring faster, safer connections. By leveraging network virtualization, users can connect efficiently, even in high-demand environments, preparing for the future of connected, autonomous vehicles.

Q & A

What is the main problem when using traditional networks for autonomous vehicles?

The main problem with traditional networks for autonomous vehicles is that they can cause significant delays due to the application data having to pass through multiple network nodes, which becomes even more problematic when the network is congested with other traffic.

How does network congestion affect the performance of autonomous cars?

Network congestion can cause delays and latency issues, which are especially critical for autonomous cars that rely on real-time communication to operate safely. This can be worsened when users in the same location are using bandwidth-heavy applications like Facebook or YouTube.

What is the role of a virtual network in addressing these issues?

A virtual network can dynamically adjust its architecture to prioritize applications based on their importance. It also allocates virtual machines accordingly, ensuring that latency-sensitive applications like those used in autonomous cars are given the necessary resources to function smoothly.

How does Network Function Virtualization (NFV) improve the performance of autonomous vehicles?

Network Function Virtualization (NFV) turns each network node into a micro-datacenter capable of hosting various applications. This allows latency-sensitive applications, like those in autonomous cars, to be hosted closer to the user, reducing communication delays and improving responsiveness.

Why is it important for autonomous car applications to have low latency?

Low latency is crucial for autonomous car applications because even a small delay in communication can lead to safety issues. Autonomous cars rely on real-time data and quick decision-making to navigate safely, so minimizing latency is essential.

What latency can be achieved for autonomous car applications with network virtualization?

With network virtualization, the communication path between the user and the application can be shortened, reducing application-server latency to as low as 1 millisecond.

How does Comarch OSS help optimize network performance for autonomous vehicles?

Comarch OSS intelligently analyzes network queries and automatically prioritizes them based on their importance. It also automates decisions regarding where applications should be hosted and how many virtual machines are needed to ensure smooth operation, particularly for latency-sensitive applications.

What is the benefit of hosting applications closer to the user in autonomous vehicles?

By hosting applications closer to the user, the communication path becomes shorter, which significantly reduces latency. This is especially important for autonomous vehicles that require real-time data processing to function effectively.

What challenges do autonomous vehicles face without advanced network solutions like NFV?

Without advanced network solutions like NFV, autonomous vehicles face delays, high latency, and potential safety issues due to the reliance on distant data centers. Network congestion and inefficient data routing can also hinder performance.

What is the overall impact of network virtualization on autonomous vehicle performance?

Network virtualization enhances autonomous vehicle performance by ensuring that latency-sensitive applications are prioritized and hosted efficiently. This leads to faster, more reliable communication between the car and its connected systems, helping to maintain safety and performance.
