2B slicing is a term that refers to the ability to create and manage multiple logical networks on top of a shared physical IP backbone network. Each logical network, or slice, can have different characteristics and performance guarantees, such as bandwidth, latency, reliability, security, etc. This way, different types of services and applications can be supported by the same IP backbone network, while meeting their specific requirements and SLAs.
2B slicing works by using technologies such as SDN, NFV, and network slicing to enable dynamic and on-demand provisioning, orchestration, and routing of end-to-end network paths across multiple domains and technologies. For example, a 2B slice can span across the access, aggregation, core, and edge segments of the IP backbone network, and use different transport technologies, such as MPLS, SRv6, or Ethernet, depending on the service needs.
