For long-term data flows such as elephant stream, mouse streams, certain paths are easy to cause using valley-fill hash Heavier loads, and other path loads are lighter, to reduce the harmony of path load.For this purpose, the prior art provides one Kind stream cluster exchanges (Flowlet Switch) scheme, comprising: long-term data flow is divided into multiple subnumbers by transmitting terminal It include at least one message, the path congestion where detecting current sub-data stream in transmitting terminal in each sub-data flow according to stream When, transmitting terminal passes through the path after current sub-data stream is sent completely, by next sub-data flow of the sub-data flow Equative route send.When the transmission time interval of two messages in a data flow is greater than preset time interval (gap), Load balancing can be carried out using above-mentioned stream cluster exchange scheme to the data flow.In general, the size of preset time interval is Empirically determined.

In the implementation of the present invention, the inventor finds that the existing technology has at least the following problems:

The prior art is the size of empirically determined preset time interval, in order to guarantee a data flow as far as possible In message there is not random ordering, usually the preset time interval is arranged it is larger, for example, the preset time interval is set It is set to 100 microseconds (us), and the size of the transmission time interval between sub-data flow actually required usually has with path status It closes, that is, when path is more unimpeded, transmission time interval actually required is usually smaller, at this point, if preset time interval It is larger, then it can reduce system performance；When path more congestion, transmission time interval actually required is usually larger, at this point, such as The preset time interval of fruit is smaller, then can cause packet out-ordering.Therefore, in the prior art using fixed prefixed time interval Scheme can reduce system performance, and packet out-ordering is also resulted in when serious.

For example, if the first VLAN message is first VXLAN message of data flow 000000000000, described the One interchanger adds list item (Flow an ID:000000000000, Sequence in the transmission table of first interchanger ID:000000000001).

Step 404, the first VXLAN message that first interchanger is sent is received in the second switch Afterwards, the second switch judge the type code position in the first VXLAN message value instruction type of message whether be Request type.

Specifically, the second switch judges whether the value of the type code position in the first VXLAN message is Two preset values, when the value of the type code position in the first VXLAN message is the second preset value, the second switch is true The type of the fixed first VXLAN message is request type.

By the description in above-mentioned steps 401 it is found that the type code position in the first VXLAN message is SA, S=1 and A When=0, type of message is request type, then second preset value can be 10.Therefore, the second switch can be according to class Whether it is request type that whether the value of type flag bit SA is 10 type to judge the first VXLAN message.

Since the value of the type code position SA of the first VXLAN message is the second preset value 10, described second hands over It changes planes and determines that the type of the first VXLAN message is request type.

Step 405, if the type of message of the value instruction of the type code position in the first VXLAN message is request class Type, then the second switch is used according to the 2nd VXLAN message of the first VXLAN Receive message, the 2nd VXLAN message In notifying second switch described in first interchanger to receive the first VXLAN message.

Wherein, the 2nd VXLAN message includes: type code position and identification information, and the value of the type code position is First preset value, the type of message that first preset value is used to indicate the 2nd VXLAN message is respond style.

Since the 2nd VXLAN message is for notifying second switch described in first interchanger to receive described first VXLAN message, therefore, the type of message of the 2nd VXLAN message is respond style, and the mark of the 2nd VXLAN message Know the identification information that information is the first VXLAN message, that is, the type code position of the 2nd VXLAN message is 01, mark letter Breath is 000000000000000000000001.

In embodiments of the present invention, the second switch the 2nd VXLAN according to the first VXLAN Receive message When message, including two kinds of acquisition modes:

First way: the second switch generates the 2nd VXLAN message according to the first VXLAN message.

Wherein, the 2nd VXLAN message of generation is dedicated for notifying the second exchange described in first interchanger Machine receives the message of the first VXLAN message, and the 2nd VXLAN message includes the tunnel VXLAN head, the tunnel VXLAN Head include type code position be 01, identification information 000000000000000000000001.

The second way: the second switch detects in the transmit queue of the second switch with the presence or absence of reversed report Text, the reversed message are the IP address that outer layer IP address is first interchanger in the transmit queue of the second switch Message, there are when reversed message described in the transmit queue, VXLAN of the second switch in the reversed message The identification information and type code position that the first VXLAN message is added in tunnel head obtain the 2nd VXLAN message.

Specifically, the second switch is according to the outer layer source IP address in the first VXLAN message, described second The transmit queue of interchanger is searched, when there are outer layer purpose IP address in the transmit queue for finding the second switch For the outer layer source IP address in the first VXLAN message message when, the second switch to the message carry out VXLAN envelope Dress, and 01 is set by the type code position SA in the tunnel VXLAN head, by the reserved field 1 in the tunnel VXLAN head It is set as 000000000000000000000001 and obtains the 2nd VXLAN message.

It should be noted that if in the transmit queue of the second switch there are multiple outer layer purpose IP address be first The message of the IP address of interchanger, then the second switch can be the first interchanger in the multiple outer layer purpose IP address IP address message in an optional message, the message is packaged to obtain the 2nd VXLAN message, it is preferable that The second switch is pending according to first in the message for the IP address that the multiple purpose IP address is the first interchanger The message sent obtains the 2nd VXLAN message.

Message processing method provided in an embodiment of the present invention, second switch is in the transmission for detecting the second switch There are when reversed message in queue, the mark of the first VXLAN message is added in the tunnel the VXLAN head of the reversed message Information and type code position obtain the 2nd VXLAN message, since the second switch is without generating new message, because This is reduced pair while realization notifies second switch described in first interchanger to receive the first VXLAN message The occupancy of the second switch system resource.

Step 406, the second switch sends the 2nd VXLAN message to first interchanger.

For example, it is 01001000 that the second switch, which sends attribute field to first interchanger, reserved field 1 The 2nd VXLAN message that identification information is 000000000000000000000001.

Step 407, after the 2nd VXLAN message that first interchanger receives that the second switch is sent, institute It states the first interchanger and judges whether the first path meets path switching condition according to the 2nd VXLAN message.

Wherein, the path switching condition may include: time-switching condition and state switching condition.

Exemplary, first interchanger can be according to the identification information and first report of the 2nd VXLAN message Whether the identification information of text is identical to judge whether the first path meets time-switching condition, when the 2nd VXLAN is reported When the identification information of text is identical as the identification information of first message, illustrate that the first path meets time-switching condition, The time-switching condition refers to: first interchanger has received the second switch and receives the first VXLAN report The notice message of text, i.e., the described 2nd VXLAN message, at this point, the first VXLAN message and subsequent first VXLAN message Between time interval meet transmission time interval requirement.It can effectively ensure that using the judgement of the time-switching condition The timing of message in data flow.

Specifically, first interchanger judges whether the value of the type code position in the 2nd VXLAN message is One preset value, the type of message that first preset value is used to indicate the 2nd VXLAN message is respond style, when described the When the value of type code position in two VXLAN messages is first preset value, first interchanger determines described second The type of VXLAN message is respond style, and then first interchanger judges the identification information in the 2nd VXLAN message Whether identical, identification information and institute when the 2nd VXLAN message with the identification information of the first VXLAN message in transmission table State the first VXLAN message identification information it is identical when, illustrate that the second switch has received the first VXLAN message, The first path meets the time-switching condition at this time.

By the description in above-mentioned steps 401 it is found that as S=0 and A=1, the type of message is respond style, therefore, First preset value can be 01, and whether first interchanger can be 01 described to judge according to type code position SA Whether the type of the 2nd VXLAN message is respond style.

Since the attribute field in the 2nd VXLAN message is 01001000, that is, the 2nd VXLAN message The value of type code position SA is first preset value 01, and therefore, first interchanger determines the 2nd VXLAN message Type is respond style, and first interchanger judges in identification information and the transmission table in the 2nd VXLAN message The first VXLAN message identification information it is whether identical, since the identification information in the 2nd VXLAN message is 000000000000000000000001, the identification information with the record of the first interchanger described in step 403 000000000000000000000001 is identical, and therefore, first interchanger determines that the first path meets time-switching Condition.

When first interchanger determines that the first path expires the time-switching condition, first interchanger is sentenced Whether the first path of breaking meets the state switching condition, wherein the state switching condition is exchanged by described first Machine is according to configuration strategy decision, for example, first interchanger can judge according to the bandwidth availability ratio of the first path The first path whether congestion, if the first path congestion, the first path meets the state switching condition, then For example, whether first interchanger can also balanced come certainly according to the load in each path at least two equative routes It is fixed whether to carry out path switching, if at least two equative routes each path load imbalance, the first via Diameter meets the state switching condition.

When first interchanger determines the first path while meeting time-switching condition and state switching condition, First interchanger carries out path switching.

It should be noted that first interchanger passes through elder generation in message processing method provided in an embodiment of the present invention Whether the type of message for judging the 2nd VXLAN message is respond style, is in the type of message of the 2nd VXLAN message When respond style, first interchanger judges the in identification information in the 2nd VXLAN message and the transmission table Whether the identification information of one VXLAN message is identical, simplifies operating procedure.

Step 408, if the first path meets path switching condition, first interchanger is being received and institute When stating the first VXLAN message and belonging to the subsequent VXLAN message of same data flow, pass through at least two articles of equative routes Two paths send the subsequent VXLAN message to the second switch.

If first interchanger determines that the first path meets path switching condition in step 407, described One interchanger receive belong to the subsequent VXLAN message of same data flow with the first VXLAN message when, it is described first hand over It changes planes and the subsequent VXLAN report is sent to the second switch by the second path at least two equative routes Text.

Wherein, second path is any one paths at least two equative routes in addition to first path.

Step 409, when the first path meets path switching condition, the second switch passes through described at least two What second path of article equative route received that first interchanger sends belongs to same number with the first VXLAN message According to the subsequent VXLAN message of stream.

It is exchanged in second path that first interchanger passes through at least two equative routes to described second When machine is sent and the first VXLAN message belongs to the subsequent VXLAN message of same data flow, the second switch is logical That crosses that second path receives that first interchanger sends belongs to the described subsequent of same data flow with the first VXLAN message VXLAN message.

It should be noted that in embodiments of the present invention, the first interchanger when for message packaging V XLAN tunnel head, after The sequence number of one VXLAN message is added up on the basis of the sequence number of previous VXLAN message, that is, first hands over Change planes the tunnel the VXLAN head of a VXLAN message after packaging when, the sequence number of previous VXLAN message is added 1, is obtained latter The sequence number of VXLAN message, for example, the first interchanger encapsulate the first VXLAN message the tunnel VXLAN head when, described first The Serial No. of VXLAN message: 000000000001, then the first interchanger is in the encapsulation affiliated data of the first VXLAN message When the subsequent packet of stream, on the basis of the sequence number of the first VXLAN message plus 1 obtains the first VXLAN message The sequence number 000000000010 of first subsequent VXLAN message, the first interchanger is in the third VXLAN for encapsulating the data flow When message, according to the method described above and so on.Due to the Serial No. 12bit of VXLAN message, for duration such as elephant streams For longer data flow, the cumulative sequence number that may result in VXLAN message overflows, therefore, in embodiments of the present invention, institute State the mark of the first interchanger identification information in the 2nd VXLAN message received and the first VXLAN message When information is identical, if the first path is unsatisfactory for path switching condition, first interchanger empties to be recorded in transmission table The first VXLAN message identification information.Wherein, the first VXLAN message that is recorded in transmission table of emptying Identification information, which refers to, sets 0 for the sequence number in the identification information of the subsequent first VXLAN message for belonging to the data flow.? In another embodiment, the first path meets path switching condition, and the storage in order to guarantee first interchanger is empty Between can efficiently use, identification information of first interchanger in the 2nd VXLAN message and the first VXLAN are reported When the identification information of text is identical, the list item of the identification information including the first VXLAN message is deleted from the transmission table.

In another embodiment, if mark in the 2nd VXLAN message that first interchanger receives Information is not identical as the identification information of the first VXLAN message, and first interchanger stored in transmission table The identification information of one VXLAN message shows that the number for having sent message of data flow belonging to the first VXLAN message is more than default When value, the sequence number of the first VXLAN message stored in transmission table is set to 0 by first interchanger, also, described first hands over Change planes receive belong to the subsequent VXLAN message of same data flow with the first VXLAN message when, pass through the first via Diameter sends the subsequent VXLAN message.

Since first interchanger is described in the identification information that determines the 2nd VXLAN message and transmission table record The identification information of first VXLAN message is identical, and it includes the first VXLAN that first interchanger is deleted from the transmission table The first VXLAN message that the list item of the identification information of message and first interchanger record in the transmission table Identification information show data flow belonging to the first VXLAN message the number for having sent message be more than preset value when, institute It states the first interchanger and empties the identification information of the first VXLAN message recorded in the transmission table and therefore save first The memory space of interchanger.

It should also be noted that, if identification information in the 2nd VXLAN message that first interchanger receives It is not identical as the identification information of the first VXLAN message, then show that the 2nd VXLAN message is not the first VLXAN The corresponding notice message of message, the VXLAN message for still thering is in the first path first interchanger to send, described first Path is unsatisfactory for path switching condition, at this point, first interchanger belongs to same data with the first VXLAN message receiving When the subsequent VXLAN message of stream, first interchanger sends the subsequent VXLAN message by the first path.
