In an embodiment, referring to fig. 1, the present invention provides a method for detecting a delay of a data center switch, where the method includes:
s100, configuring a plurality of switches of a data center into an open series mode, and configuring detection message identifications dscp of the switches into a first preset value;
specifically, referring to fig. 2, the switching center is composed of a switch SW1, a switch SW2 and a switch SW3, and assuming that the Server1 is a device that sends an IP message, the Server2 is a destination receiving device, and a transmission sequence of the IP message is from left to right, that is, the switch SW1 is a first-hop switch, and the switch SW3 is a last-hop switch; dscp (Differentiated Services Code Point), i.e. Differentiated Services Code Point.

Therefore, the IP message with the dscp value not equal to the first preset value is regarded as a common service message, and the common service message is forwarded to the destination receiving equipment among the plurality of switches.

TABLE 1 Probe data packaging Format
And 340, forwarding the IP packet carrying the detection data to a next hop switch as a new packet.
In another embodiment, the step S400 specifically includes:

and S730, in response to that the IP message to be sent is a service message, the message sending equipment configures the dscp of the message to be sent to different second preset values, and sends the IP message to be sent to a first hop switch.
In another embodiment, please refer to fig. 2 again, in order to facilitate understanding of the technical solution of the present invention, three switches are taken as an example for description below, assuming that the application scenario in the data is that Server1 is a mobile phone, server2 is a website Server, and assuming that Server1 sends an IP packet to Server2 through switch SW1 to switch SW3, specifically, the method for detecting the time delay of the data center switch includes the following steps:
step 1, firstly, network networking configuration is carried out; specifically, referring to fig. 3, the network networking configuration includes: starting Sink time delay detection from a switch SW1 to a switch SW3, and respectively configuring a switch ID (switch identification) from the switch SW1 to the switch SW3 for being used as a unique identification of the switch in a detection networking; configuring a uniform dscp (differential service code point) as a unique identifier of a detection message for a switch SW1 to a switch SW3, identifying the message received by the switch corresponding to the dscp (differential service code point) as the detection message, and processing the rest messages as common service messages; and finally, configuring the forwarding order of the switch, namely the switch SW1 is a first-hop switch, the switch SW2 is a second-hop switch, and the switch SW3 is a last-hop switch, wherein only the detection message of the switch SW3 can be uploaded to the collector, and the detection message of the enterprise switch does not need to be uploaded to the collector.
Step 2, the Server1 sends an IP message, the switch SW1 analyzes the IP message to determine whether the message belongs to a detection message or a service message, and corresponding operation is carried out according to the specific message type; specifically, referring to fig. 4, it is determined whether the dscp in the received IP packet matches the dscp of the configured probe packet: if the received ip message is not matched with the dscp (differential service code point) of the configured detection message, the ip message is regarded as a service message, and two-layer and three-layer forwarding is carried out according to the normal service message; if the received ip message is matched with the dscp of the configured detection message, the detection message is considered to be the detection message, the detection message needs to capture the timestamp of the receiving and sending direction step by step, and a detection field is packaged at the tail part of the original ip message;
step 3, if the IP message is identified as a detection message, a corresponding receiving timestamp and a corresponding entry direction port identification are marked when the exchange chip ingress is processed;
step 4, if the IP message is identified as a detection message, a corresponding sending timestamp and a corresponding output port identification are marked when the exchange chip is processed in the egress direction; the corresponding switches SW2 and SW3 also need to perform the above-mentioned steps 2-4
Step 5, judging whether the switch is the last hop switch or not; if the switch is not the last hop switch, the detection message is the same as the service message, and the detection message is normally forwarded by the second layer and the third layer; for example, neither the switch SW1 nor the switch SW2 is the last hop switch, and only the message forwarding in the normal process is needed; if the switch is the last hop switch, the detection message needs to be uploaded to a collector;
and 6, the collector receives the detection messages from the switch SW3, calculates the time delay of the whole path, and subtracts the sending time Tx _ time in the detection data (namely SW3 MD) of the last switch from the receiving Rx _ time in the detection data (namely SW1 MD) of the first-hop switch to obtain the transmission time delay of the whole path.
According to the time delay detection method of the data center switch, the switch takes a specific dscp) value in a specified IP message as a detection message identifier, when the switch receives a message corresponding to the dscp value, the message is identified as a network detection message, when the switch receives messages of other dscp values, the messages are identified as service messages, so that the detection message and the service messages are distinguished, the receiving and sending time is further encapsulated step by step at the tail of the original message belonging to the detection message, and the last hop switch sends the message to the collector, so that the time delay detection of the whole transmission path is realized.
In another embodiment, referring to fig. 5, the present invention provides a latency probe apparatus 80 for a data center switch, where the apparatus includes:
the switch configuration module 81 is configured to configure a plurality of switches of the data center to an open serial mode, and configure the detection packet identifiers dscp of the plurality of switches to a first preset value;
