TCP PEP and QoS Software Modules for the HTS Satellite Communication System

We developed TCP PEP and QoS modules using DPDK for an HTS satellite communication system for a leading satellite telecom equipment supplier.

Geostationary satellites introduce high signal delay, impacting TCP performance. Our solution employed a specialised TCP Performance Enhancing Proxy (PEP) using Intel DPDK. This approach separated and directed TCP traffic, eliminating the need for client-side configurations.

Additionally, we implemented traffic speed limits with DPDK. Due to varied client usage patterns, some users consumed more bandwidth, affecting overall communication quality. Our solution allocated specific speeds to ensure consistent, high-quality communication for all users.

System Software for High-Speed Network Data Storage

Our team is working on system software development for high-speed network storage, handling simultaneous 8K video streams from eight cameras.
A key system function involves decoding and synchronising two 8K video streams.

SPDK integration is a potential enhancement for this ongoing project.

We utilise DPDK to enhance processes by:

accessing fragmented frames, reassembling them in physical memory, and sending them for decoding while simultaneously saving to disk;
utilising zero-copy bypasses the kernel, resulting in 2–3 times performance improvement over standard methods like Linux sockets.

What is DPDK and how does it impact networking?

DPDK is an open-source library and driver suite designed for Linux. It was initially developed for Intel platforms but now supports various hardware from multiple vendors.

Efficient network handling: DPDK reduces overhead and latency, which is crucial for sectors like trading, finance, gaming, and large data centres. It enhances cybersecurity by enabling packet access and DDoS attack prevention.
Driver optimisation: DPDK drivers directly interface with the network interface controller (NIC), bypassing Linux kernel adapters and ensuring speed and simplicity through zero-copy operations.
Comprehensive API: The DPDK API offers extensive functionalities and auxiliary functions, streamlining complex tasks and operations.

Data processing with DPDK

What are eBPF and XDP, and how do they differ from SPDK and DPDK?

eBPF (extended Berkeley Packet Filter) and XDP (eXpress Data Path) are technologies utilised for high-performance packet processing within the Linux kernel.

eBPF enables the execution of sandboxed programs within the kernel, while XDP specialises in high-performance packet processing at the earliest stage of the Linux networking stack.

Conversely, SPDK and DPDK focus on enhancing data storage and packet processing at the user space level. While eBPF and XDP operate within the kernel, providing integration advantages, SPDK and DPDK operate in user space, emphasising performance optimisation and flexibility for data storage and packet processing applications.

XDP vs DPDK: What factors should I consider when choosing technologies for packet processing?

When deciding between XDP and DPDK, it's crucial to consider the practical implications:

The application's performance requirements. XDP operates within the Linux kernel, offering high-performance packet processing at the earliest stage of the networking stack, potentially providing lower latency compared to DPDK's user space processing.
The level of flexibility needed. DPDK offers extensive libraries and APIs for building custom networking applications in user space, while XDP specialises in efficient packet processing within the kernel.
Integration requirements. XDP seamlessly integrates into the Linux kernel, while DPDK requires additional setup and configuration as it operates in user space.

What are the advantages of using DPDK vs eBPF, and vice versa?

DPDK vs. eBPF is a choice that depends on specific project requirements and preferences. DPDK excels in high-performance packet processing by bypassing the Linux kernel networking stack and operating directly in user space, potentially offering lower latency and higher throughput than eBPF. DPDK also provides extensive libraries and APIs for building custom networking applications.

On the other hand, eBPF offers a flexible framework for running sandboxed programs within the kernel, not limited to packet processing. It provides seamless integration into the Linux kernel, making it ideal for tasks beyond networking, such as security, monitoring, and tracing.

Should I utilise eBPF/XDP or SPDK in my project?

Choosing between eBPF/XDP and SPDK depends on the specific requirements of your project. If your project primarily involves packet processing within the Linux networking stack, especially at the earliest stage for performance optimisation, eBPF and XDP would be suitable choices. They offer seamless integration into the Linux kernel, providing flexibility for various networking tasks.

If your project focuses on storage performance optimisation at the user space level, SPDK would be more appropriate. SPDK offers libraries and tools designed to enhance storage performance, making it ideal for storage-related applications.
