Kube-OVN v1.16.0 introduces major enhancements such as BGP/EVPN‑enabled VPC egress, a tiered SecurityGroup with expanded priority range, per‑NIC DHCP control, multi‑network NetworkPolicy annotations, full‑NIC hot migration for KubeVirt, static IP/MAC per interface, and numerous reliability, performance, and Helm chart upgrades.
This article explains the fundamentals of EVPN, how it extends MP‑BGP to provide a control plane for VXLAN, details the five EVPN route types, and shows how MAC learning, head‑end replication, and ARP suppression work in a distributed VXLAN network.
This article explains the fundamentals of Ethernet VPN (EVPN), its MP‑BGP‑based routing types, and how EVPN serves as the control plane for VXLAN, covering route formats, MAC learning, head‑end replication, host and subnet route distribution, and ARP broadcast suppression techniques.
This article provides a comprehensive guide to VxLAN technology, covering its architecture, tunneling mechanisms, NVE/VTEP roles, L2/L3 gateway designs, MTU considerations, and the integration of EVPN MP‑BGP with detailed explanations of route types and deployment scenarios.
This article explains how EVPN serves as the control plane for VXLAN, detailing its architecture, BGP route types, advantages like reduced flooding and simplified configuration, and the mechanisms for tunnel establishment, MAC learning, routing, and ARP suppression in modern data‑center networks.
This article explains the fundamentals of Ethernet Virtual Private Network (EVPN), covering its basic concepts, topology options, control‑plane mechanisms, forwarding processes for unicast and multicast traffic, and the key advantages such as load balancing, reduced mesh overhead, faster convergence, and minimized ARP flooding.
The article explains what a data center is, why interconnecting multiple data centers has become essential for scale, cross‑region access, disaster recovery, and cloud‑native virtualization, and compares two VXLAN‑based DCI architectures—end‑to‑end VXLAN and segment VXLAN—along with the key underlying technologies.
The article explains what data centers are, why interconnecting multiple data centers is essential for modern cloud, AI, and big‑data workloads, and compares two practical DCI architectures—end‑to‑end VXLAN and Segment VXLAN—detailing their underlying VXLAN, EVPN, and underlay requirements.
This article explains how VXLAN extends Layer‑2 networks over IP using UDP encapsulation, enabling seamless VM live migration and massive tenant isolation, compares VXLAN with traditional VLANs, details packet structure, VTEP/VNI roles, gateway designs, and the EVPN control plane for efficient forwarding.
VXLAN (Virtual Extensible LAN) is a network‑virtualization overlay that encapsulates Ethernet frames in UDP packets to create logical Layer‑2 domains over IP networks, enabling seamless VM migration, massive tenant isolation, and flexible gateway designs, while EVPN provides a scalable control plane for dynamic tunnel management.
This article details the evolution of 360 Qiyun's VPC solution, describing the two‑stage migration from a customized OpenStack Neutron Liberty deployment to a hardware‑assisted EVPN + VXLAN architecture, the specific network enhancements made, performance problems encountered, and the operational benefits achieved.
