Abstract
A packet network interface apparatus includes a media access control (MAC) module for constructing a packet for transmission over a packet network and a physical coding sublayer (PCS) module for encoding the packet for transmission over a physical interface. An inter packet gap module located between the MAC module and the PCS module directly transfers data to the PCS module while maintaining a certain inter packet gap by deleting or inserting idle characters. The inter packet gap module has at least one memory module for temporary storage of packet data. The modules preferably operate in a common time domain.
Claims23
A packet network interface apparatus, comprising:
- a media access control (MAC) module for constructing a packet for transmission over a packet network;
- a physical coding sublayer (PCS) module for encoding the packet for transmission over a physical interface;
- and
- an inter packet gap module between the MAC module and the PCS module for directly transferring data to the PCS module while maintaining a certain inter packet gap by deleting or inserting idle characters, said inter packet gap module comprising at least one memory module for temporary storage of packet data.
A method of establishing connection between a client and a physical interface in a packet network, comprising:
- constructing a packet for transmission over a packet network in a media access control (MAC) module;
- encoding the packet for transmission over a physical interface in a physical coding sublayer (PCS) module;
- and
- directly transferring data to the PCS module under the control of an inter packet gap module that buffers the data in blocks sized for processing by the PCS and maintains a certain inter packet gap by deleting or inserting idle characters;
- and
- wherein the modules operate in a common time domain.
