Operations may include obtaining lists of inter-Network-Element connections (inter-NE connections) between connection points of different network elements included in a network and obtaining lists of internal connections of the network elements included in the list of inter-NE connections. The operations may also include generating, based on the lists of inter-NE connections and the lists of internal connections, a global list of connection points that correspond to the inter-NE connections and the internal connections. Moreover, the operations may include generating, based on the global list of connection points, a plurality of upstream connection chains and a plurality of downstream connection chains with respect to the internal connections. In addition, the operations may include generating a list of end-to-end circuits by combining the respective upstream connection chains and the respective downstream connection chains of each respective internal connection.

A method may include obtaining a topology of an optical network. The topology may indicate multiple optical links within the optical network. The method may also include obtaining a routing metric for each of the optical links. The routing metric may be used in selecting routes through the optical network along the multiple optical links. The method may further include obtaining a signal noise tolerance of an optical signal to be routed through the optical network and adjusting routing metrics of one or more of the multiple optical links based on the signal noise tolerance of the optical signal. The method may also include after the routing metrics of the one or more of the multiple optical links are adjusted, determining a route for the optical signal through the optical network along two or more of the multiple optical links based on the routing metrics of the multiple optical links.

Novel tools and techniques are provided for implementing network experience shifting, and, in particular embodiments, using either a roaming or portable hypervisor associated with a user or a local hypervisor unassociated with the user. In some embodiments, a network node in a first network might receive, via a first network access device in a second network, a request from a user device to establish roaming network access, and might authenticate a user associated with the user device, the user being unassociated with the first network access device. Based on a determination that the user is authorized to access data, content, profiles, and/or software applications that are accessible via a second network access device, the network node might establish a secure private connection through a hypervisor or container communicatively coupled to the first network access device to provide the user with access to her data, content, profiles, and/or software applications.

Implementations described and claimed herein provide systems and methods for identification of connection areas in a telecommunications network. In one implementation, a customer set is obtained for a communications node in the telecommunications network. The customer set includes an existing connection type and a collection of network sites including the connection type is generated from the customer set. An overlay of customer sites without the connection type may be applied to the collection of network sites to generate an intersection of non-connected customer sites within the collection of network sites including the connection type. The intersection provides an indication of underserviced sites connection to the telecommunication network for potential network growth.
