Building high-performance routing brains, SD-WAN platforms, and cloud-native networking infrastructure with eBPF, SRv6, and Go/Rust.https://klaiber.me/https://klaiber.me/publications/#pub-path-tracing-kafka-2023/https://klaiber.me/publications/#pub-path-tracing-kafka-2023/Efficient and accurate processing of Path Tracing probes is essential for using Path Tracing technology to analyze and diagnose service provider networks. This paper presents a modular and optimized probe collector that addresses several performance bottlenecks. The probe collector consists of three main components: collecting, processing, and publishing. The collector component captures incoming probes from physical interfaces, while the processing component inspects and formats captured packets. Finally, the publisher component ensures efficient transmission of processed packets to designated Kafka topics. Performance evaluation under heavy traffic loads demonstrates high packet processing rates with minimal loss.Sun, 01 Jan 2023 00:00:00 GMThttps://klaiber.me/publications/#pub-srv6-controller-demo-2023/https://klaiber.me/publications/#pub-srv6-controller-demo-2023/This demo paper presents a hands-on demonstration of a dynamic, network-driven path calculation and service function chaining solution for service provider networks. The proposed solution addresses challenges associated with static service consumption, such as complex management and inability to react to network changes. By leveraging Segment Routing over IPv6 (SRv6) capabilities, our solution enables efficient and scalable path calculations, facilitating improved network service management.Sun, 01 Jan 2023 00:00:00 GMThttps://klaiber.me/publications/#pub-dynamic-service-programming-2021/https://klaiber.me/publications/#pub-dynamic-service-programming-2021/Proposes a practical solution for dynamic, event-triggered, and fast path calculations that program services and permit a so-called service chain directly in service provider backbones. Based on Segment Routing over IPv6 (SRv6) functionalities, implementing the source-based routing paradigm with native IPv6 encapsulation. Employs a cloud-native development approach for elasticity, fault-tolerance, and high performance.Fri, 01 Jan 2021 00:00:00 GMT
