Method and apparatus for multiple qualities of service to different network connections of a single network path

An integrated circuit configured to provide multiple qualities of service to different virtual network connections, the integrated circuit comprising:

• controller circuitry configured to control operations of:
• receiving a token of a cell descriptor of data traffic of a virtual network connection;
• determining whether the token is in conformance with contracted bandwidth parameters of the cell descriptor to obtain a conformance status;
• and based on the conformance status, performing one of:
• inserting the token into a first random access memory configured to store the token for immediate output;
• or
• inserting the token into a second random access memory configured to store the token for non-immediate output.

A computer-readable medium carrying one or more sequences of one or more instructions for providing multiple qualities of service to different virtual network connections, the one or more sequences of one or more instructions including instructions which, when executed by one or more processors, cause the one or more processors to perform steps of:

• receiving a token of a cell descriptor of data traffic of a virtual network connection;
• determining whether the token is in conformance with contracted bandwidth parameters of the cell descriptor to obtain a conformance status;
• and based on the conformance status, performing one of:
• inserting the token into a first random access memory configured to store the token for immediate output;
• or
• inserting the token into a second random access memory configured to store the token for non-immediate output.
