Background
With the rapid popularization of Internet networks and the rapid development of traffic, the demand for real-time monitoring and analysis of network traffic is becoming stronger in order to manage and maintain the network operation environment. The Network Tap is a Network flow duplicating equipment, it adopts the Inline mode to connect in series in the physical link between the Network equipments, under the condition of not interfering the normal communication of the Network, the flow transmitted in the Network is duplicated to a copy, then the copy is transmitted to the Network analysis equipment at the back end for processing.
For example, a messaging testing network environment as shown in fig. 1 includes a messaging tester 101, a messaging tester 102, a bypass protection device 103, a splitter device 104, and a plurality of network devices 105, such as firewall devices, network analyzers, etc., that are accessed into the network environment through the splitter device 104.
Wherein, the message transceiving tester 101 and the message transceiving tester 102 can transmit and receive test messages to and from each other through a network; the uplink ports 108, 109 of the bypass protection device 103 are connected in series to the network between the message transceiver tester 101 and the message transceiver tester 102; the downstream port of the bypass protection device 103 is connected to the upstream ports 111, 112 of the splitter device 104, and the downstream port of the splitter device 104 is connected to other network devices 105, such as firewall devices, network analyzers, and the like.
When the splitter device 104 or the network device 105 connected to the splitter device 104 fails, the bypass protection device 103 may activate its internal switch, so that the two uplink ports are directly connected inside, and thus data traffic directly enters from the port 108 and is forwarded out from the port 109; or from port 109 and forwarded out of port 108. Thus maintaining normal communication between the messaging tester 101 and the messaging tester 102 in the network environment.
When the fault of the splitter device 104 or the network device 105 is cleared, the bypass protection device 103 may disconnect the internal switch, so that the two uplink ports of the bypass protection device 103 are respectively connected to the two downlink ports, that is, the two uplink ports of the splitter device 104. At this time, the splitter device 104 needs to negotiate with the message transceiver testers 101 and 102 in the network environment, and the two parties negotiate that the uplink port of the splitter device 104 is in a normal transceiving state after passing through, so that the network device 105 is accessed to the network environment through the splitter device 104.
Currently, the time for the shunt device 104 to negotiate with the message transceiving testers 101 and 102 in the network environment is generally long; that is, after the upstream port of the splitter device 104 is physically connected to the bypass protection device 103, it needs to wait for a negotiation time before the network device 105 can normally access the network environment through the splitter device 104.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.
As used herein, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. As used herein, the term "and/or" includes all or any element and all combinations of one or more of the associated listed items.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
The inventor analyzes the negotiation process of the shunt device access network: before the shunt equipment is accessed to a network, two uplink ports of the shunt equipment need to respectively perform transceiving negotiation of an optical module with two message transceiving testers; in this process, generally, there is a difference between the times when the two uplink ports of the splitter device receive the optical signals; when one of the uplink ports receives the optical signal and starts negotiation, the other uplink port does not receive the optical signal yet and cannot open the transmitting end, so that packet loss in the negotiation process is caused, and the negotiation has to be carried out again. If the negotiation is performed again for multiple times, the negotiation time is long, and the waiting time for the splitter device to access to the network environment is long.
Based on the above analysis, the inventor of the present invention considers that the packet loss phenomenon caused by the fact that the other port is not opened in the negotiation process of one of the two ports of the splitter device is avoided in a manner of controlling the sending ends of the two uplink ports of the splitter device to be opened simultaneously, so as to avoid the process of repeated negotiation for many times, shorten the negotiation time, and achieve the purpose of fast accessing the splitter device to the network environment.
The technical scheme of the invention is described in detail in the following with reference to the accompanying drawings.
As shown in fig. 2, a communication network system provided in an embodiment of the present invention includes: a messaging device 201, a messaging device 202, a bypass protection device 203, and a splitter device 204. Further, the communication network system may further include: a plurality of other network devices 205, such as firewall devices, network analyzers, etc., are accessed into the network through splitter device 204.
The message transceiver 201 and the message transceiver 202 communicate with each other through a network, and can transmit and receive messages to each other. Preferably, the messaging device 201 and the messaging device 202 can be two messaging testers.
The bypass protection device 203 is connected in series to the network between the messaging device 201 and the messaging device 202, and specifically, as shown in fig. 2, the upstream ports 208, 209 of the bypass protection device 203 are connected in series to the network between the messaging device 201 and the messaging device 202.
When the splitter device 204, or other network device 205, fails and the technician disconnects the splitter device 204 from the bypass protection device 203, the bypass protection device 203 switches from the primary state to the bypass state. Specifically, when the technician disconnects the shunt device 204 from the bypass protection device 203, the technician inputs an instruction to the bypass protection device 203 to control the bypass protection device 203 to switch from the main circuit state to the bypass state; the bypass protection device 203 may automatically switch from the main state to the bypass state when it detects a disconnection from the shunt device 204.
After the bypass protection device 203 is switched to the bypass state, two uplink ports of the bypass protection device 203 are directly connected inside, and data traffic directly enters from the port 208 and is forwarded out from the port 209; or from port 209 and forwarded out of port 208.
When the splitter device 204, or other network device 205, has been troubleshot, the technician connects the splitter device 204 to the bypass protection device 203. Specifically, the technician connects the upstream ports 211, 212 of the splitter device 204 with the two downstream ports of the bypass protection device 203.
After the splitter device 204 is connected to the bypass protection device 203, the flow of a method for the splitter device 204 to access the network quickly may include the following steps, as shown in fig. 3:
step S301: the bypass protection device 203 switches the own device from the bypass state to the main state after the splitter device 204 is connected to the own device.
Specifically, after connecting the shunt device 204 to the bypass protection device 203, a technician may input an instruction to the bypass protection device 203 to control the bypass protection device 203 to switch from the bypass state to the main state; alternatively, the bypass protection device 203 automatically switches from the bypass state to the main state after detecting the connection with the splitter device 204.
After the bypass protection device 203 is switched from the bypass state to the main state, the two upstream ports 208, 209 of the bypass protection device 203 are directly connected to the upstream ports 211, 212 of the splitter device 204, respectively, through the internal switch. The optical modules of the splitter device 204 connected to the two upstream ports of the bypass protection device 203 may receive optical signals via the bypass protection device 203.
Step S302: when the splitter device 204 detects that the ports of the optical modules of the two uplink ports both receive optical signals, the transmitting ends of the two optical modules are simultaneously set from the closed state to the open state.
Step S303: the splitter device 204 negotiates with the two message sending and receiving devices, and after the negotiation is passed, normal message sending and receiving can be performed.
Because the two optical modules of the splitter device 204 simultaneously receive the optical signals, the two sending ends are simultaneously opened, so that the phenomena that when one port receives the optical signals and starts negotiation, the other port cannot open the sending end because the optical signals are not received yet, negotiation fails and re-negotiation has to be performed again due to the fact that data packets cannot be forwarded are avoided, the negotiation can be completed once, the process of repeated negotiation is avoided, the negotiation time is shortened, and the purpose that the splitter device is rapidly accessed into the network environment is achieved.
Preferably, after the splitter device 204 is connected to the bypass protection device 203, the flow of another method for the splitter device 204 to access the network quickly may include the following steps, as shown in fig. 4:
step S401: the splitter device 204 sets two data ports of a switch chip connected to the bypass protection device in the device to a forced open state after the bypass protection device 203 is connected to the device.
Specifically, after connecting the splitter device 204 to the bypass protection device 203, a technician may input an instruction to the splitter device 204 to set two data ports of a switch chip, to which the splitter device 204 is connected, to a forced open state.
Or, after the splitter device 204 detects that its upstream port is connected to the bypass protection device 203, it automatically sets two data ports of the switching chip connected to the bypass protection device in the device to be in a forced open state, and sends a state switching notification signal to the bypass protection device 203.
Step S402: the bypass protection device 203 switches from the bypass state to the main state.
Specifically, the bypass protection device 203 may be switched from the bypass state to the main state after receiving an instruction input by a technician; the bypass state may be switched to the main state in accordance with a state switching notification signal transmitted from the splitter device 204.
Step S403: when the splitter device 204 detects that the ports of the optical modules of the two uplink ports both receive optical signals, the transmitting ends of the two optical modules are simultaneously set from the closed state to the open state.
Step S404: the splitter device 204 negotiates with the two message sending and receiving devices, and after the negotiation is passed, normal message sending and receiving can be performed.
Since both data ports of the switching chip of the splitter device 204 have been set to the forced open state before the bypass protection device 203 is switched from the bypass state to the main state. Therefore, in the negotiation process, the process of judging the opening condition of the data port of the exchange chip can be omitted, the negotiation time is shortened, and the purpose of accessing the network more quickly is achieved.
An internal structure block diagram of the above-mentioned flow divider device 204, as shown in fig. 5, includes: an optical module 501, a switch chip 502, and a control unit 503.
The optical module 501 includes an optical module with an uplink port and an optical module with a downlink port.
The control unit 503 is configured to set sending ends of two optical modules (i.e., optical modules of an uplink port) connected to the bypass protection device 203 from a closed state to an open state simultaneously when the ports of the two optical modules receive optical signals.
Then, the switch chip 502 may negotiate with the message transceiver device through the ports of the two optical modules via the bypass protection device 203, and after the negotiation is passed, the switch chip is in a normal message transceiving state.
Further, the control unit 503 may be further configured to set two data ports of a switch chip connected to the bypass protection device in the present device to be in a forced open state after the bypass protection device 203 is connected to the present device.
After setting the two data ports to the forced open state, the control unit 503 may further send a state switching notification signal to the bypass protection device 203 to instruct the bypass protection device 203 to switch the bypass state to the main state.
In the technical scheme of the embodiment of the invention, because the two optical modules of the splitter device simultaneously open the two sending ends under the condition of simultaneously receiving the optical signals, the phenomena of negotiation failure and renegotiation caused by incapability of forwarding data packets because the other port cannot open the sending end because the other port does not receive the optical signals when one port receives the optical signals and starts negotiation are avoided, the negotiation process can be completed once, the negotiation time is shortened, and the purpose of rapidly accessing the splitter device into a network environment is achieved.
Further, since the two data ports of the switching chip of the splitter device have been set to the forced open state before the bypass protection device is switched from the bypass state to the main circuit state. Therefore, in the negotiation process, the process of judging the opening condition of the data port of the exchange chip can be omitted, the negotiation time is shortened, and the purpose of accessing the network more quickly is achieved.
