The alternate path may be periodically updated. A plurality of alternate paths may be maintained. The alternate paths may not have any links in common. User traffic may be rerouted substantially simultaneously to each link of the alternate path in the event of failure of a primary path.

The advanced intelligent network (AIN) to determine routing of voice calls alternatively between the public switched telephone network (PSTN) and a data packet network, such as the Internet, in accordance with the quality of service existing in the data packet network at the times of call origination. The user's acceptable level of service may be predefined with a threshold quality level stored in the user's Call Processing Record (CPR) in the AIN Integrated Services Control Point (ISCP). On a per call basis, the caller linked to a first public switched network may indicate a preference to route through the Internet. This indication is recognized by the AIN system, in response to which the quality of service currently present on the Internet for completion of the call is measured. If the result exceeds the stored threshold, the call is setup and routed through the Internet to the switched network link to the destination party. If the quality of service on the Internet is not satisfactory, the call is alternatively routed through the PSTN, which may include an Interexchange Carrier link. The AIN system automatically controls the alternative routing of such calls.

A method and architecture for secure transmission of data within optical-switched networks. In one embodiment, the optical switched network comprises a photonic burst-switched (PBS) network. Under various schemes, security keys including encryption and decryption keys are generated by edge nodes and the decryption keys are distributed to other edge nodes in a PBS network. In one embodiment, the security keys are dynamically generated by a trusted platform module (TPM). A source edge node uses its encryption key to encrypt selected data bursts to be sent to a destination edge node via a virtual lightpath coupling the source and destination edge nodes. Security data are embedded in a control burst header indicates to the destination node whether corresponding data bursts sent via the virtual lightpath are encrypted. The security data also includes the decryption key and may also identify an encryption/decryption algorithm to be used. In some embodiments, public key infrastructure facilities are used in conjunction with employment of private and public keys and digital certificates.
