Technical Field

Background

The Fiber Channel (FC) protocol is a high-speed serial communication protocol, and has the characteristics of high bandwidth, high reliability, low delay, flexible topology structure and openness. In order to meet the application requirements of the FC protocol in avionics communication systems, a plurality of FC protocol clusters suitable for avionics environments have been established.

However, at present, switches accessed to an FC switching network by terminals in the aerospace field all use static configuration, that is, network operation parameters are manually specified before initialization, and equipment information is identified according to the initial operation parameters after a system is started, so that network communication is performed. There is also an access mode based on dynamic configuration, which is mainly completed through DHCP protocol and WINS service. The DHCP protocol is used for the server to dynamically distribute the IP address for the terminal, and the WINS service is used for centrally managing the access information of the terminal in the network so as to inquire the information of a target computer during communication.

The static configuration and the dynamic configuration can effectively complete the access of the terminal to the FC switching network, but are limited by the diversity of the FC protocol cluster, and at present, there is no general method for the terminal meeting the requirement of multiple FC protocol clusters to access to the FC switching network.

In addition, the main application scenario of the embodiment of the invention is FC, and the FC is mainly applied to an avionic communication system and is suitable for an avionic environment. The protocol supporting the FC operation of the avionics communication system is called FC protocol, in which there are different terminals and switches at the same time to serve the normal operation of the avionics communication system.

It should be explained that, in different FC protocols, the types of terminals are different, and the interaction mode between the terminals is also different. For example, in the FC-AE-1553 protocol, terminals are divided into a Network Controller (NC) and a Network Terminal (NT), and the interaction mode between the two is command-response type; in the FC-AE-ASM protocol, the terminals are again peers, but different FC protocols generally rely on the switching network of fig. 1.

Fig. 1 is a conventional FC switching network, in which a switching network is required to be relied upon when there is a communication demand between terminals and between a terminal and a switch in the switching network.

It should be explained that, the embodiment of the present invention completes the automatic maintenance of the connection state of each terminal in the FC switching network link, depending on the primary switch and the secondary switch. Only one main exchanger is arranged in the exchange network, and the other main exchangers are auxiliary exchangers; the main switch is responsible for maintaining the terminal connection state of the whole network and providing a uniform interface for other terminals to inquire the terminal connection state in the switching network, and the auxiliary switch is only responsible for maintaining the terminal connection state of the auxiliary switch; when there is a change in the terminal connection information of the subordinate switch, it is necessary to synchronize the change information with the principal switch.

In the embodiment of the present invention, a first terminal and a second terminal are taken as an example, and for convenience of description, terminal access information request terminals of the first terminal and the second terminal are respectively split to describe a process of accessing the first terminal and the second terminal to a switch, in addition, the first terminal is connected with a main switch, the second terminal is connected with a sub-switch, and fig. 2 is shown in a detailed example.

It should be sequentially explained that the terminal access information table refers in particular to a set of terminal information that is accessed to the FC switching network and can communicate normally, each terminal information includes a terminal name, a terminal address, a connected switch identifier, and the like, and other information can be added according to actual needs. In the embodiment of the invention, the terminal access information table comprises a whole network and a local branch, wherein the whole network terminal access information table is maintained by the main switch, and the local terminal access information table is maintained by the auxiliary switch.

Further, when the terminal accesses the switching network again after being started and connected for the first time or after being disconnected, an address needs to be allocated to the terminal, and taking the first terminal as an example, the detailed execution process includes:

transmitting a login protocol of the first terminal to the master switch;

and generating an allocation address of the first terminal in the main switch, filling the allocation address into the login response frame, transmitting the login response frame back to the first terminal, simultaneously acquiring terminal information comprising a terminal name, a terminal address and a connected switch identifier of the first terminal, and storing the terminal information into a whole network terminal access information table of the main switch.

In addition, in another embodiment of the present invention, when the first terminal actively exits the switching network, data interaction with the master switch is also required, and the detailed execution process includes:

generating a network switching quitting communication request at the first terminal based on the network switching quitting communication protocol, and sending the network switching quitting communication request to the main switch;

when the main switch receives the switching network quitting communication request, deleting the terminal information of the first terminal in a whole network terminal access information table of the main switch;

and when the terminal information of the first terminal is deleted successfully, generating the quit response frame and feeding the quit response frame back to the first terminal to finish the process that the first terminal quits the exchange network actively.

Similarly, referring to fig. 2, the second terminal corresponds to the sub-switch, and when the second terminal logs in or logs out of the switching network, the second terminal is similar to the first terminal, and the main difference is that the second terminal information can be directly written in the local terminal access information table of the sub-switch or deleted. And the second terminal information needs to utilize the auxiliary switch to connect the main switch, and then the second terminal information is inserted or deleted in the whole network terminal access information table of the main switch.

Fig. 3 is a schematic flow chart of a method for obtaining a connection state of a terminal based on an FC switched network according to an embodiment of the present invention. In this embodiment, taking the first terminal as an example, the method for obtaining a connection state of a terminal based on an FC switched network in a general manner includes:

s1, receiving a request connection frame of a terminal, and sending the request connection frame to a pre-constructed main switch;

it should be explained that there is only one main switch in the switching network, and the other switches are auxiliary switches, the main switch is responsible for maintaining the terminal connection state of the whole network, and providing a uniform interface for other terminals to inquire the internal terminal connection state of the switching network, the auxiliary switches are only responsible for maintaining the terminal connection state of the auxiliary switches, and when the terminal connection information of the auxiliary switches changes, the change information needs to be synchronized to the main switch.

In the embodiment of the invention, when the terminal prepares to enter the switching network, the terminal needs to directly execute the communication protocol conversion with the switch, and the terminal is not permitted to enter the switching network until the requirement of the communication protocol conversion is met.

It should be explained that the terminal and the master switch or the slave switch each include an LS _ REQ: link State Request (network node connection State Request protocol, connection State Request protocol for short) and LS _ ACK: link State Acknowledge protocol (network node connection State Acknowledge protocol for short).

Specifically, referring to fig. 4, the generating a connection request frame according to the connection status request protocol includes:

s11, generating a universal frame according to the structural information of the pre-constructed universal frame and an FC network standard;

s12, changing the frame type of the general frame to obtain a request connection frame with information to be perfected;

s13, acquiring the ID of the main switch and the ID of the terminal;

and S14, combining the ID of the main switch and the ID of the terminal to the request connection frame with information to be completed to obtain the request connection frame.

It should be explained that the universal frame of the present invention is a protocol supporting the FC operation avionics communication system, i.e., a universal frame format of the FC protocol, and one of the universal frame formats is shown in fig. 5 and mainly includes SOF, CRC, EOF, a universal frame header, and Data _ Field. The SOF, CRC, EOF, and Data _ Field are common technical identifiers in the communication Field, and are not described herein again.

With reference to fig. 5, we continue to refine the structure of the generic frame header, as shown in fig. 6. As shown in fig. 6, the generic frame header includes R _ CTL, D _ ID, S _ ID, payload, and the like, where D _ ID is an ID of a device that receives an FC frame, S _ ID is an ID of a device that transmits the FC frame, R _ CTL is set to 0x22, and Payload is referred to as Payload.

In the embodiment of the present invention, the changing the frame type of the general frame to obtain the connection request frame whose information is to be perfected includes:

and extracting the frame serial number of the connection request frame sent by the terminal, and filling the frame serial number and the frame type value into the universal frame to obtain the connection request frame with information to be completed.

In the embodiment of the present invention, the frame type value of the request connection frame is 0xA7.

It should be explained that the frame number of the connection request frame refers to a REQ _ Num field in the payload format of the LS _ REQ frame, and is gradually incremented by times, where if the terminal sends the connection request for the first time, the corresponding frame number is 0, and if the terminal sends the connection request for the second time, the corresponding frame number is 1.

In detail, the payload format of the request connect frame is shown in fig. 7. A total of 8 bytes in payload format of the LS _ REQ frame. Req _ Num is the sequence number of the LS _ Req frame sent by the terminal, and is used to identify each LS _ Req frame.

In this embodiment of the present invention, the sending the request connection frame to a pre-constructed master switch includes:

judging whether the terminal is directly connected with the main switch or not;

In detail, when the connection request frame needs to be forwarded through the secondary switch, the secondary switch identifies whether the frame is received for the first time according to the S _ ID and the Req _ Num, if so, the frame is forwarded from the cascade port, otherwise, the frame is directly discarded. The request connection frame reaches the primary switch through a plurality of times of forwarding of the secondary switch.

S2, judging whether the connection request frame is sent to the main switch for the first time or not;

in this embodiment of the present invention, the determining whether the connection request frame is sent to the master switch for the first time includes:

and judging whether the connection request frame is sent to the main switch for the first time or not according to whether the main switch has a historical frame serial number and an ID which are the same as the frame serial number and the ID of the terminal or not.

Further, the generation process of the request response frame is similar to that of the request connection frame, and the main difference lies in a frame type value corresponding to the request response frame in the frame type value taking table, for example, the frame type value of the request connection frame is 0xA7, and the frame type value of the request response frame is 0xA8.

In detail, the payload format of the request response frame is shown in fig. 8. The length of the request response frame depends on the number of pieces containing the terminal information. Each piece of terminal connection information in the request response frame includes: SW _ Num (identification of terminal connection switch), node _ ID (address of terminal), and Node _ Name (Name of terminal).

In the embodiment of the present invention, the method for determining whether the connection request frame is sent to the secondary switch for the first time is the same as the method for determining whether the connection request frame is sent to the primary switch for the first time, and mainly checks whether the historical frame number and the ID that are the same as the frame number and the ID of the terminal can be found in the secondary switch, which is not described herein again.

If the request connection frame is sent to the main switch for the first time, executing S3, extracting terminal information in the main switch, and packaging according to the terminal information to obtain a request response frame;

in the embodiment of the invention, the terminal information can be acquired from the whole network terminal access information table of the host switch, the terminal information comprises a terminal name, a terminal address, a connected switch identifier and the like, and other information can be added according to actual requirements.

In the embodiment of the present invention, the method for generating the terminal information includes:

Since the specific implementation process of writing the terminal information into the local terminal access information table is similar to that described above, it is not described herein again.

In the embodiment of the present invention, the obtaining of the request response frame according to the encapsulation of the terminal information includes:

and packaging the terminal information to the request response frame with information to be perfected to obtain the request response frame.

It should be explained that, in the embodiment of the present invention, the terminal information is encapsulated into Payload in the request response frame.

If the request connection frame is not sent to the master switch for the first time, executing S4 and not responding to the request response frame;

it will be appreciated that since there may be multiple routes between two switches, the same request connection frame may be forwarded to the master switch via different routes, resulting in the master switch repeatedly receiving the request connection frame, and therefore, when the request connection frame is not first sent to the master switch, there is no need to respond to the request reply frame.

And S5, transmitting the request response frame back to the terminal to obtain terminal connection state information.

In detail, when the request response frame needs to be forwarded through the secondary switch, the secondary switch identifies whether the frame is received for the first time according to the D _ ID and the Ack _ Num, if so, the frame is forwarded from the cascade port, otherwise, the frame is discarded. The request response frame is forwarded to the request end through the secondary switch for a plurality of times. The terminal connection state information includes a set of terminal information that accesses the FC switching network and can normally communicate.

Based on the background technology: static configuration and dynamic configuration can effectively complete the access of the terminal to the FC switching network, but are limited by the diversity of the FC protocol cluster, and a general method for the access of the terminal meeting multiple groups of FC protocol clusters to the FC switching network does not exist at present. In order to solve the problem, in the embodiment of the present invention, switches in an FC switching network are divided into a main switch and a sub switch, where the main switch is responsible for maintaining a terminal connection state of a whole network, the sub switch is only responsible for maintaining a terminal connection of itself, and a connection of any terminal ultimately depends on a control of the main switch over the terminal connection state of an entire interactive network, when a terminal requests a network connection state, a different response policy is performed on the request connection frame by determining whether the request connection frame is sent to the main switch for the first time, if the request connection frame sent by the terminal is sent to the main switch for the first time, terminal information corresponding to the terminal is obtained, and the request response frame is obtained by encapsulating according to the terminal information, and if the request connection frame is not sent to the main switch for the first time, the request response frame is not sent to the main switch, so as to avoid a possibility of repeatedly receiving the request response frame. Therefore, the invention makes the two access strategies into an organic interface, and can maximally realize the phenomenon of terminal access failure caused by different protocols. Therefore, the method, the device, the electronic device and the computer readable storage medium for universally acquiring the connection state of the terminal based on the FC switching network, provided by the invention, can solve the problem that the terminal can not be universally accessed to the FC switching network due to the diversity of the FC protocol cluster.
