Embodiment
The information transferring method and the system of equipment room in a kind of Ethernet of the present invention, its core concept be, in the Ethernet during equipment room Data transmission, some information is carried in the source MAC field of Frame and sends.First, second equipment of the present invention is meant the equipment with transmitting-receiving ethernet data frame, for example switch or router, and, first equipment can advance data encapsulation in the Frame source MAC field, second equipment can come out this data read after receiving this equipment, first, second equipment can directly link to each other, and also can carry out indirect connection by other network equipments.
Shown in Figure 3, be the execution mode flow chart of the information transferring method of equipment room in the Ethernet of the present invention, it may further comprise the steps:
As shown in the figure, at first carry out step S11, the relevant information of the information that actual needs is sent is encapsulated into the source MAC field, and the source MAC field is no longer carried source MAC.
Preferred implementation is: with data first equipment the relevant information of processing of process be encapsulated into the source MAC field, the payload field of Frame part still encapsulates through the data after first device processes simultaneously.And prior art is: the payload field at Frame partly encapsulates through the data after first device processes, and what the source MAC field encapsulated is the MAC Address of source device.Therefore the present invention has just comprised data result after treatment simultaneously in an ethernet data frame, and data the data such as concrete processing type, process, parameter of process.In fact, the content that the source MAC field is carried can be varied, except the relevant information of aforesaid process information, can also carry the preliminary treatment result of first equipment, first equipment receives the original port of data, even the required data of carrying of Frame payload field, irrelevant owing to carrying which kind of specifying information and emphasis of the present invention, repeat no more herein.
The relevant information of the information that the first equipment actual needs sends is the content that actual package is advanced the source MAC field, it is relevant with the information that the first equipment actual needs sends, but may not comprise the information that the real actual needs of first equipment sends, this relevant information can directly comprise the information that actual needs sends, but is not limited thereto.Because the source MAC field only has 48 capacity, when therefore the information that sends when actual needs surpasses source MAC field capacity too much, just can't directly send, can send the information that actual needs sends separately with other Frame this moment, perhaps send to set up prolate-headed mode at the head of frame or afterbody, and relevant informations such as the send mode of the information that only sends at source MAC field record actual needs and sequence number thereof, so that the information and date frame payload that actual needs is sent partly carries out association.
In addition, because technology such as ATMoE, the present invention also is not subject to only bearing IP packet, and can carry the data that all transmit based on Ethernet.
Then carry out step S12, first equipment sends the Frame after the encapsulation, carries the relevant information that needs transmission information in the source MAC field of Frame.As previously mentioned, for source MAC field limited bits or other reasons, this relevant information can comprise the information itself that actual needs sends, and also can be the relevant informations such as send mode, sequence number of the information of actual needs transmission.This first equipment for example is the preposition equipment in the background technology.
Carry out step S13 then, second equipment receives the Frame after the encapsulation, and the transmission of Frame and reception technique are to be familiar with the technology that the those of ordinary skill of Ethernet is all known, so also repeat no more at this.In the present embodiment, second equipment for example is the background devices in the background technology, has the ability of receiving data frames.
Carry out step S14 at last, second equipment obtains the relevant information of the information that the first equipment actual needs sends from the source MAC field of the ethernet data frame that receives.
Second equipment can obtain the information that actual needs sends according to this relevant information.Encapsulate the into difference of the source MAC field contents of Frame according to step S11: when the relevant information of encapsulation has comprised the information of the real actual needs transmission of first equipment itself, read this field contents and can obtain the information that the first equipment actual needs sends; When since the length of the information that the first equipment actual needs sends greater than 48 or because other reasons, and the information that the first equipment actual needs is not sent encapsulates into Frame source MAC field, then second equipment is according to the difference of this related information content indication, from the head or the afterbody extension header of Frame, perhaps from other Frames of this relevant information association, obtain the information that the first equipment actual needs sends.
Because equipment such as switch are for the correct needs of transmitting data, the source MAC of the automatic learning data frame of meeting, and be recorded into the MAC Address list item, and the source MAC field is no longer carried source MAC and is changed the relevant information of the information that the carrying first equipment actual needs sends in the Frame of the present invention.Therefore, learn to cause overlapping for avoiding switch that it is used as source MAC with real source MAC, cause the MAC Address of switches learn mistake to occur, simultaneously also receive whenever that for fear of switch a Frame just learns to cause the MAC Address list item not enough.Therefore, the embodiment of the invention when transferring data frames with frame in the first place of source MAC field contents be changed to 1.After the first place of source MAC field contents was set to 1, Frame can be judged as multicast or broadcast frame by switch, and can not read its source MAC and this address is recorded into the MAC Address list item.
In addition, both can make all different source MAC fields only carry a kind of in the above-mentioned relevant information.Also can make the different pieces of information frame have the ability of carrying different relevant informations, at this moment, need distinguish, can carry dissimilar relevant informations to realize the different pieces of information frame with certain position.
Following examples stay three to represent to control type of message in highest byte, and the information that sends with actual needs is specifically described the source MAC field for the control information with load information is an example below:
000 keeps;
Directly carry the control information that the first equipment actual needs sends in 001 this Frame source MAC field of expression, for example be carried in low 5 bytes of source MAC field;
The source MAC field of 010 this Frame of expression is not carried control information, there is the proprietary extensions head in this data frame header, in order to carry the control information that the first equipment actual needs sends, the non-emphasis of the present invention of details such as the formal definition of this heading, the present invention does not do specific descriptions, and first byte can be used for defining version number information and length information;
The source MAC field of 011 this Frame of expression is not carried control information, there is the proprietary extensions head in this Frame afterbody, in order to carry the control information that the first equipment actual needs sends, details the present invention such as its formal definition do not do specific descriptions, and first byte can be used for defining version number information and length information;
The source MAC field of 100 these Frames of expression is not carried control information, what carry is the relevant information of control information, represent that the information that the first equipment actual needs sends sends with other Frame separately, this Frame is the control information frame, comprise the sequence number that control information and data message can be connected in this source MAC field, sequence number can be placed in the field of low 32 of source MAC;
The source MAC field of 101 these Frames of expression is not carried control information, what carry is the relevant information of control information, represent that the information that the first equipment actual needs sends sends with other Frame separately, this Frame is the load information frame, comprise the sequence number that control information frame and load information frame can be connected in this source MAC field, sequence number can be placed in the field of low 32 of source MAC.
Other reservations.
The Frame transmission flow is as follows on first equipment:
If (control information＜=5 bytes)
{
Adopt 001 mode to encapsulate transmission
}
Else if (expansion back message load＜=1500 bytes)
{
Adopt 010 mode to encapsulate transmission
}
else
{
Get sequence number
Adopt 100 modes to encapsulate and send control information, and in the source MAC field padding sequence number
Adopt 101 modes to encapsulate the transmission data message, and in source MAC address information padding sequence number
The sequence number stepping
}
The control information of transmitting when needs is during less than 5 bytes (40bits), can adopt 001 data frame format, need not expand message format, in this case to using and the impact minimum of equipment, information is transmitted and handles also the most efficient, and second equipment can be directly reads control information from the source MAC field of the Frame of receiving.
When needs carry a large amount of control information (greater than 5 bytes), above-mentioned two kinds of single bag extended modes and a kind of many bag extended modes of also having defined.Single bag extended mode is mainly used in the situation that does not need burst, carries control information and load information solution efficient and stationary problem at Dan Bao like this.When message is long when needing burst after expanding, the present invention has defined the mode that a kind of control information and load information send respectively, separates the burst problem of IP message by no means.Receive the Frame of 010 or 011 form when second equipment after, second equipment just can read control information from the head or the afterbody of this Frame; Receive the Frame of 100 or 101 forms when second equipment after, represent that these frame data have partly carried control information or load information, second equipment reads control information acquisition sequence number from the source MAC field of Frame, and this frame and the other frame that has carried load or control information are associated, thereby obtain control information and load information by this sequence number.
