Welcome everyone. My name is Ti Patel from DRC system LLC. Today I will walk you through how Rust can help solve the problems and the safety challenges of next generation 5G. This talks brings together my experience in system level architecture and my current research into rust based network system. We will begin with the core performance challenges of 5G. Then I will explain Rust unique strength that makes it deal for the system programming. We will dive into real world implementation for traffic management. I will share the benchmark result and with the practical techniques you can use in your work. 5G system requires extremely low latency under five milliseconds, and to end the must handle massive concurrency and maintain. Near perfect reliability, whether traditional language like C and c plus thread memory, safety for speed, which introduce risk and a safe language like Java, or go struggle with the real time guarantee due to garbage collection. Why traditional approach falls apart. CNC plus offers speed, but at the cost of MA safety leading to issue like a buffer overflows, manual memory management, slow down development, and increased bucks language with the garbage collector like Java and a go are safer, but unpredictable. Because of pauses, make them unsuitable. For the realtime 5G workloads, we need a solution that's both fast and safe. That was rust Come in. Rust unique advantage for the 5G system. Rust, give us a mammary safety without a garbage collector. Thanks to its ownership model, its zero Cost. Abstraction mean you get the high level core with the C. Like performance. Fearless concurrency is built in rust. Prevent data, racist. At compile time and even when you need low level control, rust unsafe blocks are scoped and the control ensuring overall system safety. Smart network manager architecture. So here's a Simplifi architecture for the high performance 5G Traffic manager. The radio interface layer process packets are synchronously using zero copy buffer. The traffic classification engine uses rust types system for the compiled time optimized matching the routing core handle log free concurrency and the performance mam. Safe DMA operation for fast, safe routing, zero copy networking in cc plus. You have to manually manage mammary if you forget to free. You get a leak or crash rust model. Let us use slices to create a zero copy views of data safety. Memory is automatically released when it goes out of scope. No leaks, no crashes. This model help us achieve both safety and a high throughout. So there is a, our system achieves like 4.2 milliseconds, end to end latency even under heavy load, well under the five milliseconds target. We show 300% throughout the gain compared towards similar c plus implementation. CPU usage dropped by 65%. Freeing up resources. And over 18 months of deployment, zero mammary safety, P memory bandwidth improvements. Rest zero copy techniques greatly reduce how much data we have moved around in the mammary that not only increase speed, but also reduce the strain on hardware, making it idle for the resource constrained environment like H devices. Advancing pattern. So rust is a sync or a weight model help us. The non-blocking code that's both fast and reliable. We use the custom custom futures and the stream combinator to protect packets efficiently. Unlike callback based in model rust approach avoids spaghetti code with the cutting down memory usage. Rust type system in a hidden superpower for performance. With the compiled time polymorphism, we write generic code that compiles into highly optimized routines. No runtime cost. The type state pattern and code app state in a system, eliminating whole classes of runtime bucks. Memory safe. DMA operations DMA is accessed in traditionally dangerous, but we can wrap it up. Safe rest abstraction. Here we define the DMA buffers struck and implement cleanup in a safe way using. The result. Direct Hardware access with the safety guarantees sometime previously only possible with the risky code. Rest, give us a performance without compromise, sub family. Second lesson, latency and a total. Memory safety, its ownership model allows for zero copy data. Race free networking you can adapt in incrementally. Start by replacing critical components in CNC plus system without a full rewrite. REST is not just a safe language, it's the next generation system language that 5G infrastructure demand.
