Cisco Connect Toronto 2018 network-slicing
2 likes2,118 views
The document discusses network slicing, which is the partitioning of network resources and functions to run selected applications, services, or connections in isolation from each other for specific business purposes. This allows mobile operators to offer virtual private networks on a common infrastructure through network slicing on an end-to-end basis across access, transport, and core networks. Slicing enables new revenue opportunities through network slices optimized for different vertical industries while simplifying service delivery and management.
