  • Methods and apparatus for use in providing transport and data center segmentation in a mobile network
    Patent number: 11463353
    Abstract: In a mobile network, an identity of a security group associated with user equipments (UEs) may be obtained. A segment route (SR) path for session communications in the mobile network for the UEs may be selected based on the identity of the security group. The SR path may be one of a plurality of SR paths in a transport network used by the mobile network and defined at least in part by one or more segment IDs (SIDs). An identity of a virtual network associated with the security group may also be obtained. The selected SR path and the identity of the virtual network may be provisioned in one or more routers of the transport network, such that IP messages communicated for the UEs in the mobile network are forwarded via the selected SR path and (at least ultimately) via the tunnel associated with the security group.
    Type: Grant

    Date of Patent: October 4, 2022
    Assignee: CISCO TECHNOLOGY, INC.
