This article explains the evolution of Segment Routing, its core concepts such as Segments, SIDs and Segment Lists, and how SR‑MPLS and SRv6 improve MPLS forwarding, TE, and data‑center overlay networking with UDP and load‑balancing techniques.
This article traces the evolution of wide‑area network technologies, explains MPLS label‑stack architecture and forwarding mechanisms, details MPLS VPN (L2VPN/L3VPN) components, routing information bases, RD/RT fields, and outlines classic and inter‑domain deployment models for modern carrier networks.
This article explains how BIGO’s backbone network achieves high availability through a three‑layer design—control‑plane HA using ETCD‑based Raft leader election, data‑plane HA with MPLS SR‑Policy and intermediate Route‑Reflection layers, and business‑level HA that combines traffic, optimization, and fault scheduling to ensure seamless service continuity.
This article explains Segment Routing (SR) and its SRv6 extension, covering their inheritance from MPLS, the SRv6 packet format, SID structure, node roles, endpoint instructions, and how Best‑Effort and Traffic‑Engineering policies are implemented and forwarded in modern networks.
ICBC’s Software Development Center overhauled its star‑topology network by deploying MPLS VPN, eliminating a central hub, reducing costs, establishing optimal point‑to‑point paths, and enabling seamless expansion, thereby boosting reliability, performance, and supporting future R&D growth across multiple locations.
This article compares VXLAN and MPLS, explaining how VXLAN’s lower hardware costs, looser edge‑core coupling, and broader engineer expertise make it a more attractive overlay solution for modern metro and wide‑area networks.
The article compares VXLAN and MPLS, explaining their underlying virtualization concepts, cost and operational differences, and demonstrates why VXLAN is increasingly favored over MPLS for metro‑area and wide‑area network deployments due to lower hardware costs, simpler engineering, and flexible overlay capabilities.
This article provides a comprehensive overview of Multiprotocol Label Switching (MPLS), covering its origins, definition, working principles, architectural components, label operations, LSP creation, and deployment methods, illustrating how MPLS enhances routing efficiency, VPN services, traffic engineering, and QoS in modern networks.
This comprehensive guide explains what Traceroute is, how it works, its limitations, and advanced techniques such as DNS reverse lookup, handling asymmetric paths, MPLS tunneling, and multi‑path routing, helping network engineers diagnose latency and routing issues more accurately.
