20090257757 | SIGNAL IDENTIFICATION IN OPTICAL COMMUNICATIONS NETWORKS - Signals in an optical communications network, such as optical channels in an optical WDM network for example, are each identified by at least two low frequency dither tones with which the signal is modulated. The dither tones alternate with a predetermined periodicity to produce a cyclically repeated sequence of dither tones. A network parameter, such as a channel identifier for example, is obtained by the detection of the particular combination of dither tones in the sequence. To detect a number of network parameters a signal is modulated with a number of cyclically repeated sequences of dither tones each uniquely identifying a respective network parameter. In some implementations each dither tone in a cyclically repeated sequence of dither tones is repeated with substantially the same phase and coherent averaging is performed over a number of periods to detect dither tones on low power signals. | 10-15-2009 |

20150229618 | System and Method for Securing Source Routing Using Public Key based Digital Signature - Embodiments are provided for securing source routing using public key based digital signature. If a protected source route is tampered with, a public key based method allows a downstream node to detect the tampering. The method is based on using digital signatures to protect the integrity of source routes. When creating a source route for a traffic flow, a designated network component computes a digital signature and adds the digital signature to the packets. When the packets are received at a node on the route, the node uses the digital signature and a public key to verify the source route and determines accordingly whether the source route has been tampered with. If tampering is detected, the receiving node stops the forwarding of the packets. | 08-13-2015 |
