Embodiment Construction

[0062] In the following embodiments, the control flag codeword is a special 10-bit K28.5 codeword as an example for illustration, and the processing methods for other types of control flag codewords are completely the same.

[0063] Since the special code word K28.5 of the control character in the FC frame is a 10-bit code word, the K28.5 code word must be converted into a special 8-bit code word, such as 0xab, in order to realize transparent transmission in the PSN network , the present invention provides following two processing methods:

[0064] method one:

[0065] The sender converts K28.5 in all FC frames (including ordinary FC frames, primitive sequences, and primitive signals) into special characters (such as 0xab), and the data field is still transmitted according to the original byte code. The format of SOF, EOF, primitive sequence and primitive signal encoded in this way is shown in Figure 6, including 8-bit special characters (such as 0xab) and 24-bit complete dat...

Abstract

The invention relates to a method for transmitting FC frame in pack exchange network, and a relative pack exchange network and node. Wherein, said method comprises: converting the control mark code of FC frame as FC common frame, and/or FC original signal frame and/or FC original sequence frame, into 8-bit code, to be packed into clear load domain of PWE3 report, to transmit it in pack exchange network. Said node comprises PSN report processing module, PW processing module connected to the PSN report processing module, FC processing module, FC frame coding/decoding converting module, and FC physical interface module. Said network structure uses said pack exchange network node to connect FC network.

Description

technical field [0001] The invention relates to fiber channel technology, and particularly discloses a method for transmitting FC frames in a packet-switching network, a packet-switching network structure and nodes applying the method. Background technique [0002] FC (Fiber Channel, Fiber Channel) technology is a series of standards established by ANSI (American National Standards Institute, American National Standards Institute) for network and channel I / O interfaces. The medium is isolated, so that multiple protocols can be transmitted on the same physical connection at the same time, and the high-performance storage body and broadband network use a single I / O interface, which greatly reduces the cost and complexity of the system. It uses the principle of full-duplex serial communication to transmit data, with high transmission rate (the transmission rate is 1G, 2G, etc.), coupled with its standardization and openness of standards, it has been rapidly adopted in SAN (Stor...
