Huawei'sSD-WAN multi-fed and selective receiving technologyis not limited to5G links. This technology can be applied to various types of WAN links, including MPLS, Internet, LTE, and 5G, to optimize traffic steering and improve reliability.The multi-fed feature allows multiple links to be used simultaneously, while selective receiving ensures that the best path is chosen for each application based on real-time conditions.
This flexibility makes the technology applicable across diverse network environments, not just 5G.

Comprehensive and Detailed in Depth Explanation:An MPLS (Multiprotocol Label Switching) network uses Label Switched Paths (LSPs) to forward packets. However, an LSP is unidirectional , not bidirectional. This means that the path is established in one direction only, from the ingress Label Edge Router (LER) to the egress LER. For bidirectional communication, two separate LSPs are required-one for each direction.
This concept is critical in understanding MPLS architecture, as it ensures efficient packet forwarding based on labels rather than IP addresses. The unidirectional nature of LSPs allows for better traffic engineering and control over data flow in MPLS networks.
