In the Xinghe Intelligent Campus solution, "Network Slicing" is used to provide hard or soft isolation for different services (e.g., separating video conferencing from guest Wi-Fi). The three primary implementation solutions (resource isolation methods) defined in the HCSP V2.0 curriculum are:
FlexE (Flexible Ethernet) (A): Provides physical-layer hard isolation by dividing the MAC/PHY interface into slots.
Flex-channel (Flexible Channel) (C): A Huawei-patented technology that provides dedicated bandwidth with nearly zero interference.
Channelized sub-interface (D): Uses sub-interfaces with reserved bandwidth to provide logical isolation.
Slice ID (B) is an identifier carried in the packet header (such as the IPv6/SRv6 extension header) used to map traffic to a specific slice; it is a label/identifier , not the underlying resource isolation technology implementation itself.
