A method of automatically provisioning a network-wide function using a plurality of network elements in a service provider network and using a sub-network level approach is provided. In one specific approach, a software wizard facilitates provisioning a bi-directional line switched ring (BLSR). First user input, specifying a plurality of ring attribute values that define attributes of a bi-directional line switched ring, is received. Second user input, specifying one or more working spans for the bi-directional line switched ring, is received. Each of the network elements is automatically configured to participate in the bi-directional line switched ring based on the parameter values. Embodiments may provide a software wizard for implementing the foregoing process. In certain features, spans for a BLSR are automatically selected based on a selection of a first candidate span; only selected nodes and spans that are capable of participating in a BLSR are displayed; and port orientation for all spans in a BLSR is automatically determined based on user input defining port orientation for a first port of a first span.

Techniques for implementing a firewall in a gateway network element between two IP based networks is provided. Packets can be filtered out that specify the gateway network element as the source, where the packet comes from the network that is not visible to the other network. For example, if a packet on DCC going to the gateway network element specifies the gateway network element as the source, the packet can be discarded.

A method and system for representing a low-order connection and a high-order connection as a single circuit are disclosed. The method includes creating a low-order listener object and a low/high listener object at each end point of the low-order connection and creating a high-order listener object at each end point of the high-order connection. The low/high listener objects are matched with the high-order listener objects to create a link and represent the connections as a single circuit.
