Fixed core意思

"Fixed core" is a term used in the context of telecommunications and networking, particularly in relation to fiber optic networks. It refers to a type of network architecture where the core infrastructure, which is the high-speed backbone of the network, is fixed and does not change.

In a fixed core network, the central part of the network remains static and does not adapt or change to accommodate different types of traffic or varying user demands. This means that the routes and connections within the core are predetermined and do not dynamically adjust to optimize performance or efficiency.

Fixed core networks are typically found in traditional telecommunications networks where the infrastructure was designed and built to serve a specific purpose and user base. These networks may not be as flexible or scalable as newer, more dynamic network architectures that use technologies like Software-Defined Networking (SDN) or Network Function Virtualization (NFV).

In contrast, a "flexible core" or "dynamic core" network is designed to be more adaptable, allowing for changes in routing, bandwidth allocation, and network functions in real-time. This type of network is better suited to handle the growing demands of modern communication, including the Internet of Things (IoT), cloud services, and high-bandwidth applications like video streaming and online gaming.
