Abstract:
1. A data processing apparatus, comprising: a processor; a computer-readable storage media storing one or more sequences of instructions which when executed by the processor causes the processor to perform: receiving first user input specifying a plurality of ring attribute values that define attributes of a bi-directional line switched ring for provisioning on network elements of one or more non-connected sub-networks; receiving second user input specifying one or more working spans for the bi-directional line switched ring; automatically configuring each of the network elements to participate in the bi-directional line switched ring based on the ring attribute values; determining whether the ring attribute values specify a 4-fiber bi-directional line switched ring (BLSR); receiving third user input specifying a selection of ports for protect spans when the ring attribute values specify a 4-fiber BLSR; displaying a list of one or more BLSRs that are then-currently provisioned in a service provider network, wherein each of the BLSRs is associated with a ring identifier value; receiving a selection of one of the BLSRs in the list; generating and displaying a network topology display that includes only those network elements of the service provider network that participate in the selected BLSR.
