Abstract
A method for processing a received packet in a MAC (Medium Access Control) layer of an Ethernet which receives a packet from a physical layer and transmits the received packet to a switch. The method includes the steps of detecting an error while receiving the packet from the physical layer; upon failure to detect error, transmitting the received packet to the switch; and, upon detection of error, stopping the transmission of the received packet to the switch.
Claims3
A method for processing, by an Ethernet MAC (Medium Access Control) layer, a packet received from a physical layer and intended, after reception, for storage in a storage memory at the MAC layer and transmission, after storage of the packet in said storage memory, to a layer above the MAC layer, the packet having a size, comprising:
- detecting for error while receiving, at the MAC layer, said packet from the physical layer;
- and,
- upon detection of error,
- a) regardless of said size, preventing the storage, of said packet, in said storage memory at the MAC layer, thereby preventing said transmission to said layer above;
- and
- b) sending, to said layer above, a signal indicating occurrence of error and a signal indicating an end of said packet.
