BGP Peering Patterns for Kubernetes Networking at Preferred Networks - Sho Shimizu, Preferred Networks, Inc. & Yutaro Hayakawa, Isovalent at Cisco

Tuesday June 17, 2025 14:10 - 14:40 JST

Level 1 | Pegasus A-B1

BGP (Border Gateway Protocol) is increasingly being used to connect Kubernetes networking with the rest of the IT estate, especially in large-scale and on-premises environments. However, the complexity of many network architectures requires users to have more flexibility and control over how they deploy BGP. Based on the experience at Preferred Networks, this session introduces key BGP peering patterns that enhance Kubernetes networking while maintaining operational simplicity, including:

1. The Sidecar BGP Peering Pattern: A method of running a dedicated BGP speaker alongside Kubernetes networking components, balancing automation with fine-grained control.
2. Native Routing over IP Clos Networks – A tunneling-free approach that integrates Kubernetes with large-scale BGP-based datacenter fabrics for better performance.

Based on real-world experience, we will share best practices and lessons learned, helping attendees design scalable and reliable Kubernetes networking with BGP.

Reimagining Cloud Native Networks: The Critical Role of DRA - Lionel Jouin, Ericsson Software Technology & Sunyanan Choochotkaew, IBM Research

Tuesday June 17, 2025 15:50 - 16:20 JST

Level 1 | Orion

As AI/ML, high-performance and telecom workloads are progressing in their cloud-native journey, the unique platform requirements inherent to the nature of their functionality are exposing the limitations of existing solutions such as Multus and device plugins. Device Resource Allocation (DRA) offers a fresh approach overcoming these challenges with better resource management for non-homogeneous platforms, topology-aware use cases and beyond! By leveraging the latest Kubernetes features, DRA Drivers are redefining the network interface configuration and enhancing capabilities for multi-network deployments. This talk explores the evolving cloud-native networking landscape and the trade-offs between extending Kubernetes and leveraging add-on components. We will delve into recent advancements including the network device status with KEP-4817, the virtual device allocation with KEP-5075 and the role of the CNI-DRA-Driver in shaping the future of cloud-native networking infrastructure.
