Based on above-mentioned steps 102a1,102a2, step 102 is specifically included:
102a3, the second timestamp is parsed from the second congestion message, the second moment was determined according to the second timestamp.
Wherein, above-mentioned flow table includes to need to add the congestion type of message mark of the congestion message of timestamp.
In a kind of example, which includes the type of message mark of congestion message, and includes the congestion type of message mark
The corresponding processing mode of congestion message of knowledge.Illustratively, which can be made of matching rule and controlling behavior two parts,
In general, being then directed to should when needing the type of message for carrying out matched message mark to meet matching rule defined by flow table
Message executes the corresponding controlling behavior of the matching rule, wherein above-mentioned controlling behavior can be to abandon (drop), do not abandon
(drop cancle), it redirects, modify the operation behaviors such as message content, traffic statistics.For example, flow table as shown in table 1 below is shown
It is intended to it is found that when needing the type of message mark of matched message to meet the matching rule of flow table, i.e. the message class of the message
When the format of type mark is made of specified byte and user's designated ends slogan, then the message redirecting is controlled to CPU.
Table 1
Flow table in the embodiment of the present invention, which is applied, is sending the direction Egress, and the matching rule in flow table is congestion message class
Type mark, controlling behavior be redirect switching equipment CPU (due to existing exchange chip do not have record the time function,
And the CPU of switching equipment has the function of record time, it is therefore desirable to by the CPU of congestion message redirecting to switching equipment), because
This switching equipment matches congestion message by flow table, and when determining addition timestamp, congestion message is sent to CPU,
Timestamp is added to congestion message by CPU.Switching equipment parses the congestion message by CPU addition timestamp, obtains phase
At the time of answering.
It should be noted that flow table can be applied in both direction: receiving Ingress and send Egress.When flow table is answered
Used in the direction Ingress is received, then this flow table only matches the message of receiving direction；It applies and is sending when flow table
The direction Egress, then this flow table only matches the message of sending direction.
In addition, above-mentioned timestamp is the timestamp of the Microsecond grade of switching equipment CPU addition or the time of higher precision
Stamp.
It in the present embodiment, is the timestamp of Microsecond grade or higher precision with the second timestamp due to first time stamp, because
This, the interval for stabbing the second moment corresponding with the second timestamp at corresponding first moment at the first time is also Microsecond grade or more high-precision
The time interval of degree then transmits momentary rate according to the data that the message transmission rate above determined is switching equipment outlet end,
The message transmission rate of outlet end when the momentary rate can more accurately embody switching equipment congestion.
Optionally, above-mentioned congestion message can be by integrating congestion notification function, for example, exchange core on exchange chip
When on piece integrates CN (English: Congestion Notification, Chinese: congestion notification agreement) function, when the unlatching CN function
When energy, congestion message CNM (English: Congestion can be generated when congestion occurs for the gate region of switching equipment
Notification Message, Chinese: congestion notification message) message.In the present embodiment, in switching equipment in exchange chip
Generated first congestion message and the second congestion message can be CNM message.Wherein, the message format of CNM message such as Fig. 3
Shown, the content that each field of CNM message indicates is as shown in table 2.
Table 2
Illustratively, above-mentioned CNM message is that the data information from exchange chip sampled targets gate region obtains,
In:
The address purpose mac=sampled data information source address mac of CNM message；
The local address mac of the address mac=interchanger in the source of CNM message；
CnmQOffset=Qcur-the Qeq, Qcur of CNM message indicate queue length when present sample；
CnmQDelta=Qcur-the Qold, Qold of CNM message indicate queue length when last sampling；
The exit port of congestion and the queue at place occur for the cnmCPID of CNM message, CPID；
Preceding 64 bytes of CNM message Encapsulated MSDU=sampling message.
Illustratively, as it appears from the above, switching equipment parse congestion message, i.e., above-mentioned CNM message, such as:
1, as the Encapsulated MSDU for parsing above-mentioned CNM message, it can be deduced that the relevant information of data source such as source
The mac/l4 port numbers etc. of the source the ip/ mac/ mesh of ip/ mesh.
2, as the CPID for parsing above-mentioned CNM message, it can be deduced that the position for generating congestion, such as outlet end and outlet team
Column.
3, when the cnmQOffset for parsing above-mentioned CNM message, the congestion situation of available congestion queue.
From the foregoing, it will be observed that by the CNM message for parsing exchange chip generation and feeding back to user, user can recognize out
The concrete condition of congestion occurs for mouth queue.
Optionally, above-mentioned congestion message be switching equipment open congestion notification function period in generate, but
It is the limitation due to exchanges device capabilities, when above-mentioned first threshold is smaller, due to the message mistake of exchange chip generation
It is more, it will lead to switching equipment and break down, it is therefore desirable to the congestion notification function of exchange chip be limited, can be passed through
Following two ways are limited.
Mode 1: congestion notification function is periodically opened and closed.
Illustratively, first time interval and the second time interval can be set by being configured to exchange chip.
Wherein, first time interval is that congestion notification function opens a duration, and the second time interval is congestion notification function
Close a duration.
Mode 2: when exchange chip generates the congestion message of fixed quantity, closing the congestion notification function of exchange chip,
And exchange chip congestion notification function is opened at the time of fixing.
Illustratively, the first data and third time interval can be set by being configured to exchange chip.Its
In, the first data are the population size of the congestion message generated when congestion notification function is opened, and third time interval is logical for congestion
It accuses function and closes a duration.
The realization of above two mode can make this programme be suitable for more switching equipment.
It should be noted that the use of user for convenience, when user needs not look at switching equipment outlet end transmission speed
When rate, the congestion notification function of exchange chip is closed, when user needs to check switching equipment outlet end transmission rate, opens and hands over
Change the congestion notification function of chip.In the present embodiment, congestion notification function is to open.
