    • The Logical Connection form enables you to define a logical connection by describing its configuration and connection details.

    Logical Connection form

    The Logical Connection form enables you to describe the details for a logical connection.

    Table 1. Logical Connection form
    Field Description
    Name Name of this logical connection The ServiceNow AI Platform uses this name to identify it in your network inventory.
    Max percent over subscription Percent of subscription allowed for a logical connection with respect to the bandwidth.
    Topology
    Topology of the network connection:
    Point to point
    Connects two nodes directly together with a common link
    Point to multi-point
    Provides multiple connections from one point to multiple points Point to multiple points.
    Multi-point to multi-point
    Complex topology in which each node can communicate with multiple other nodes
    Unidirectional ring

    Fiber ring in which the signal is sent in one direction only.

    Bidirectional ring

    Fiber ring in which the signal is sent in both directions simultaneously.

    Mesh
    Network topology in which the infrastructure nodes connect directly, dynamically, and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data to and from clients
    Topology group
    Defines how nodes and devices are connected in a network with each other
    Linear chain
    Network topology where each device connects one after the other in a sequential chain
    Radio access network
    Connects end-user devices, like smartphones, to the cloud.
    Mobile core network
    Enables subscribers to get access to the services that they’re entitled to use. It’s responsible for critical functions such as subscriber profile information, location, service authentication, and necessary switching tasks.
    Mobile transport network
    Connects the core network and the RAN (Radio Access Network) of the mobile network

    Logical Connection form - Configuration

    The Configuration section in the Logical Connection form enables you to create a logical connection.

    Table 2. Logical Connection form - Configuration
    Field Description
    Port A

    Network interface that is used in the Port A connection. Select the search icon ( Search icon.) and select a network interface. To learn more, see Define the network interface details.
    Bandwidth AtoZ

    Total bandwidth capacity from Site A to Site Z for this network connection.
    Framing type Type of frame used in the connection. Select one of the following:
    • None
    • AMI
    • B4ZS
    • B8ZS
    Protocol version Protocol version number.
    Endpoint role
    Endpoint role that is associated with the service endpoint for this network asset. An endpoint role is the function that is served by the endpoint of the service that you’re providing. Select one of the following options:
    • ROOT or LEAF endpoint role, as defined by the Metro Ethernet Forum (MEF).
    • --None-- for no assigned endpoint role.
    Port Z

    Network interface that is used in the Port Z connection. Select the search icon (Search icon.) and select a network interface. To learn more, see Define the network interface details.
    Bandwidth ZtoA

    Total bandwidth capacity from Site Z to Site A for this network connection.
    Cost

    Cost of this network asset.
    Distance

    Route length of this connection, expressed in the unit of measure that you select in the Unit field.
    Unit
    Unit of measure in which you’re expressing the route length of the connection in the Distance field. Select one of the following options:
    --None--
    No distance measurement expressed for the connection route length.
    Miles
    Distance is expressed in miles.
    Kilometers
    Distance is expressed in kilometers.
    Feet
    Distance is expressed in feet.
    Meters
    Distance is expressed in meters.
