FlexE Virtual Link Multiplexing for Asymmetric Traffic

Multiple MAC clients share a common FlexE virtual link for upstream data transmission instead of each having a dedicated link. The patent implements this by creating a shared virtual link that carries upstream traffic from multiple MAC clients, thereby reducing total bandwidth occupation and physical medium requirements while maintaining transmission reliability through proper resource management and flow control mechanisms.

A single FlexE virtual link serves multiple MAC clients for upstream transmission, making the link universal rather than dedicated. The patent enables this shared link to handle traffic from different MAC clients by implementing appropriate multiplexing and identification mechanisms, allowing one link to perform multiple functions and serve multiple purposes.

The patent introduces flow control frames as intermediary elements to manage the shared FlexE virtual link. These frames act as mediators between multiple MAC clients and the shared link, coordinating data transmission, preventing congestion, and managing resource allocation. This intermediary mechanism enables efficient sharing without requiring complex peer-to-peer coordination between all MAC clients.

The patent implements dynamic flow control mechanisms that adjust transmission parameters based on real-time link conditions. Flow control frames carry dynamic information about link status, buffer levels, and congestion states, allowing the system to adaptively manage the shared link resources. This dynamic approach simplifies the static complexity by introducing flexible, condition-based control rather than rigid predetermined allocations.
