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 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.
The article details UCloud's next‑generation backbone network architecture, describing its intelligent controller, SR‑TE routing, MP‑BGP/L2VPN designs, control‑plane and forwarding‑plane mechanisms, and how these enable a smart, reliable, and highly schedulable cloud‑wide transport fabric.
This article examines how UCloud’s rapidly expanding cloud services drove a series of backbone network upgrades, detailing the transition from the original MPLS‑based design to a Segment Routing (SR‑TE) architecture that delivers intelligent, reliable and programmable traffic engineering across global data‑center regions.
This article explains how UCloud leverages Segment Routing to redesign its backbone network, detailing the architecture, control‑plane and forwarding‑plane designs, traffic‑engineering features, multi‑scenario access, and future evolution to achieve intelligent, reliable, and highly schedulable connectivity.
This article examines the rapid evolution of UCloud's data‑center network, detailing the challenges of scaling MAN and backbone infrastructures, the transition from Backbone 1.0 to 2.0, and how Segment Routing and SR‑TE enable intelligent, reliable, and programmable cloud connectivity.
