Abstract
A node configured to support multi-service with Flexible Ethernet (FlexE) includes circuitry configured to receive a client signal, wherein the client signal is different from a FlexE client; and circuitry configured to map the client signal into a FlexE shim. A method, implemented in a node, for supporting multi-service with Flexible Ethernet (FlexE) includes receiving a client signal, wherein the client signal is different from a FlexE client; and mapping the client signal into a FlexE shim.
Claims16
A node configured to support multi-service with Flexible Ethernet (FlexE), the node comprising:
- circuitry configured to receive a client signal;
- circuitry configured to map the client signal into a FlexE shim;
- and
- timing circuitry configured to transmit adaptation and timing information (Cn) in reserved FlexE overhead fields, wherein a second node connected to the node is configured to receive the adaptation and timing information (Cn) and utilize a specific operational code in FlexE to rate adapt the client signal based on the adaptation and timing information (Cn).
A method, implemented in a node, for supporting multi-service with Flexible Ethernet (FlexE), the method comprising:
- receiving a client signal;
- mapping the client signal into a FlexE shim;
- and
- transmitting adaptation and timing information (Cn) in reserved FlexE overhead fields, wherein a second node connected to the node is configured to receive the adaptation and timing information (Cn) and utilize a specific operational code in FlexE to rate adapt the client signal based on the adaptation and timing information (Cn).
A network supporting multi-service with Flexible Ethernet (FlexE), the network comprising:
- a plurality of nodes interconnected to one another, wherein a FlexE group is configured between two nodes;
- wherein each of the two nodes comprise
- circuitry configured to receive a client signal,
- circuitry configured to map the client signal into a FlexE shim, which is transmitting over the FlexE group,
- timing circuitry configured to transmit adaptation and timing information (Cn) in reserved FlexE overhead fields;
- and
- rate adaptation circuitry configured to utilize a specific operational code in FlexE to rate adapt the client signal based on the adaptation and timing information (Cn).
