Segment Routing (SR) introduces a source routing model where the source node defines the path that packets take through the network by imposing a list of segments (instructions).

SR is aligned with SDN principles — the network is programmable and flexible.

SR does NOT depend on LDP or RSVP. Instead, SR uses extensions to IGP (OSPF or IS-IS) or BGP to distribute segment information.

SR simplifies the control plane by reducing the number of protocols needed for label distribution.

SR can work with or without a controller — the controller enhances path computation but is not mandatory for basic SR operation.

Huawei defines thecore technical fields of campus networksas:

WLAN (Wireless LAN)

Wired LAN (Switching Network)

SD-WAN, when used forbranch interconnectionwithin enterprise campuses

WAN, on the other hand, is a broadercarrier-class infrastructureandnot specifically categorized as a campus network technology. It refers to long-distance, backbone, or ISP-level connectivity beyond the scope of typical enterprise campus deployments.

In adata center network, thephysical connection componentstypically include:

Access switches(connect to servers)

Core/Aggregation switches(form the backbone of the network)

Optical fibers(used for high-speed physical links between switches)

Whileservers are connected to the network, they arenot considered part of the network's physical infrastructure (connection components)— they are endpoints or resources hostedonthe network, notcomponents ofthe physical connection infrastructure.
