  • Patent number: 10567352
    Abstract: Systems and methods for Physical Coding Sublayer (PCS) encryption implemented by a first network element communicatively coupled to a second network element include encrypting a Flexible Ethernet (FlexE) signal based on a first encryption key with encryption applied to a 64b/66b bit stream associated with the FlexE signal at one or more of a FlexE client layer and a FlexE shim layer; switching to a second encryption key at a predetermined point in the FlexE signal; and encrypting the FlexE signal with the second encryption key subsequent to the switching.
    Type: Grant

  • Patent number: 10193688
    Abstract: Systems and methods for Physical Coding Sublayer (PCS) encryption implemented by a first network element communicatively coupled to a second network element include utilizing an encryption messaging channel to establish an authenticated session and exchanging one or more encryption keys with a second network element; encrypting a signal, based on the one or more encryption keys; and transmitting the encrypted signal to the second network element.

  • Patent number: 8054853
    Abstract: The present invention provides systems and methods for supporting native TDM and native Packet switching simultaneously in a meshed switching architecture. Specifically with the present invention, the meshed links are common to both TDM and packet traffic, and both types terminate to a common system interface without the need to separate physical resources and infrastructure; the common termination function has access to both the TDM (Time Slot Interchange (TSI)) switching and packet switching elements. Native TDM switching and packet switching operate in concurrently in the mesh over common links, with the personality of the links derived by the card type (attached to the mesh). In this, a given card or slot in a system can communicate in the native format to both packet based cards (slots) or TDM based cards (slots) simultaneously with no preconceived restrictions or limitations on slot or link definition.
