Abstract
Embodiments of a device and method are disclosed. In an embodiment, an Ethernet communications device includes a physical layer (PHY) unit or a media access control (MAC) unit configured to perform media access control for the Ethernet communications device. The Ethernet communications device includes a security unit configured to manipulate a data stream in a data path within the Ethernet communications device when the data stream violates or conforms to a pre-defined policy.
Claims20
An Ethernet communications device comprising:
- a physical layer (PHY) unit;
- or
- a media access control (MAC) unit configured to perform media access control for the Ethernet communications device,
- wherein the Ethernet communications device comprises a security unit configured to manipulate a data stream in a data path within the Ethernet communications device when the data stream violates or conforms to a pre-defined policy.
A method of operating an Ethernet communications device, the method comprising:
- determining whether or not a data stream in a data path within the Ethernet communications device violates or conforms to a pre-defined policy;
- and
- manipulating the data stream when the data stream violates or conforms to the pre-defined policy.
A communications network comprising:
- a shared media;
- and
- a plurality of Ethernet communications devices configured to communicate via the shared media, wherein each of the Ethernet communications devices comprising:
- a physical layer (PHY) unit;
- or
- a media access control (MAC) unit configured to perform media access control for the Ethernet communications device,
- wherein each of the Ethernet communications devices comprises a security unit configured to manipulate a data stream in a data path within the Ethernet communications device when the data stream violates or conforms to a pre-defined policy.
