Network system-wide error handling utilizing control bit modification
First Claim
1. A communication interface for handling errors between network devices, comprising:
- an output interface of a first network device for generating output control information and output parity information carried in output information transmitted therefrom; and
an input error-handling interface of a second network device, which input error-handling interface is in operative communication with the output interface to detect errors in the output information.

Abstract
A communication interface for processing errors between network devices. The communication interface includes an output interface of a first network device for generating output control information and parity information of output information transmitted therefrom, and an error-handling interface of a second network device, which error-handling interface is in operative communication with the output interface to process the output control information and the parity information of the output information by, checking parity of the parity information of the output information received from the first network device, terminating the output information when an error in the parity is detected, and recovering a boundary of the output information when an error in the output control information is detected.

49. A method of handling errors in a network device, comprising the steps of:
-
receiving input information of an input port with an input error-handling interface of the network device;
checking parity on the input information with the input error-handling interface to detect erred information and error-free information;
terminating the erred information by performing one of discarding the erred information, forwarding an error-free portion of the erred information, and forwarding all of the erred information;
transmitting with an output interface output information that includes the error-free information, output control information, and parity information.
