Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The connection management method provided by the application can be applied to the application environment shown in fig. 1. Wherein, the request end 102 communicates with the target end 104 through the network. Before data is sent, two parties communicating with each other need to establish a connection, and after the data is sent, the two parties communicating with each other need to be disconnected, so that connection management is a guarantee for realizing reliable transmission of the two parties.

The requesting end 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the target end 104 may be implemented by an independent server or a server cluster composed of a plurality of servers.

The CM plays a very important role in the process of establishing a connection by using a transmission technology, which implements some events on the drive side, and a user can know what phase the current connection is in the process of establishing the connection by using the events so as to perform corresponding processing subsequently, where the transmission technology includes RDMA (Remote-Direct Memory Access).

The RDMA technology has the advantages of an emerging network Transmission technology, the basic principle of which is similar to that of the traditional TCP technology (Transmission Control Protocol), and a connection establishing process is also provided.

The RDMA technology allows direct access from the memory of one host to the memory of another host, and the process of establishing a connection is greatly different from the conventional transmission technology, and besides the connection establishment phase, there is a protocol layer establishment phase, which is complex in the process of establishing a connection and requires corresponding error handling when an error may occur in each step.

In one embodiment, as shown in fig. 2, there is provided a connection management method, including the steps of:

in step 201, the connection manager obtains the excitation parameters of the management queue.

The excitation parameters of the management queue can be regarded as events in the creation process of the management queue, and different events represent the excitation parameters of different management queues.

Illustratively, when an event of an anomaly or power failure occurs in the peer network, the event may be regarded as obtaining the CONN _ DISCONNECT, which is an excitation parameter.

Step 202, determining a corresponding second management queue state and a management queue operation instruction from a preset state transition table according to the excitation parameter of the management queue and the first management queue state of the state machine.

The state transition table is a two-dimensional array table, as shown in fig. 3, where a row element represents a possible management queue state, at a certain time, the state machine is in one of the management queue states, the management queue state is a first management queue state, a column element represents different scenarios occurring in the management queue creation (i.e., obtained excitation parameters of different management queues), and a certain structure array is determined by the row element and the column element, and the elements of the structure array include: the next state to jump (i.e., the second managed queue state) and the managed queue operation instruction.

The management queue operation command is a set of necessary operation commands required for completing the state transition, and is determined by the transmission technology itself.

Step 203, the connection manager executes the management queue operation instruction to create a management queue, and converts the first management queue state of the state machine into a second management queue state.

Illustratively, when the first management queue state is the "initial state", the excitation parameter of the management queue, which is the "request for creating the management queue", is acquired, it is determined that the management queue operation instruction is "prepare resource", the request end is notified that the connection request has been received, the management queue is created, and the second management queue state is "create complete", the management queue operation instruction is executed, and the first management queue state "initial state" of the state machine is converted into the second management queue state "create complete".

Step 204, the connection manager obtains excitation parameters of the IO queue.

The excitation parameters of the IO queue (i.e. IO queue) can be regarded as events in the IO queue creation process, and different events represent the excitation parameters of different IO queues.

Step 205, determining a corresponding second IO queue state and an IO queue operation instruction from the state transition table according to the excitation parameter of the IO queue and the first IO queue state of the state machine.

It can be understood that, in the state transition table, a row element further has an element representing an IO queue state where the state machine may be located, at a certain time, the state machine is in a certain IO queue state, the IO queue state is a first IO queue state, a column element further has an element representing different scenarios occurring in the creation of the IO queue (that is, excitation parameters of different IO queues can be considered to be obtained), and the row element and the column element together determine a certain structure array, where the elements of the array structure include: the next state to jump (i.e. the second IO queue state) and some operations (i.e. IO queue state operation instructions) required to implement this state jump.

And step 206, the connection manager executes the IO queue operation instruction to bind the IO queue to the created management queue, and converts the first IO queue state of the state machine into a corresponding second IO queue state.

In the connection management method, aiming at the management queue creation and IO queue creation in the protocol layer establishment process, the state machine is adopted to realize the state jump in the whole process, and relevant scenes and states in the protocol layer establishment process are packaged in the state conversion table, so that compared with the traditional code compiling mode, the method simplifies the implementation mode of a program, reduces the number of codes and has clearer logic; and the addition of the new scene task can be realized only by maintaining the content in the two-dimensional array at the later stage.

It should be understood that, although the steps in the flowchart of fig. 2 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in fig. 2 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.

In the actual connection process, the faced scenario is more complex, and exemplarily illustrates that the first management queue state has an inheritance relationship with the second management queue state, and in one embodiment, there are three management queue states:

state 1: idle 'disconnect';

and 2, state: establishing a connection;

state 3: is connected.

At the same time, there are three possible occurrences (i.e., stimulus parameters that manage the queue):

excitation parameters 1: establishing a connection request;

excitation parameters 2: completing connection establishment;

excitation parameters 3: the link request is broken.

The state machine is started in the state 1: the idle 'disconnection' is a first management queue state, and the excitation parameter 1 is obtained: establishing a connection request, executing a corresponding management queue operation instruction 1 'to prepare resources, notifying a request end that the connection request is received', and converting the state of the first management queue into a second management state, namely, converting the state 1: idle 'off' transitions to state 2: establishing a connection;

thereafter, "state 2: in establishing a connection, "as a new first management queue state, after obtaining the excitation parameter 2: when the connection is established, executing a corresponding management queue operation instruction 2 'informing a user that a command can be transmitted and a resource for sending the command is prepared'; and converts the new first managed queue state to a new second managed queue state "state 3: connected ".

As above, when obtaining the excitation parameter 3: after the link request is disconnected, executing a management queue operation instruction 3 "disconnect and destroy resources", and setting a first management queue state "state 3" of the state machine: connected "transition to" state 1: idle 'disconnect'.

In one embodiment, the state machine is a multi-stage state machine comprising a one-stage state machine for instructing management of queue state jumps and providing operational instructions for implementing state transitions;

And a first-level state machine is adopted to independently realize the state conversion of the management queue creating process and record the current state of the management queue creating process.

determining a corresponding second IO queue state and an IO queue operation instruction from the state transition table according to the excitation parameter of the IO queue and the first IO queue state of the state machine, including:

and determining a corresponding second IO queue state and an IO queue operation instruction from the state conversion table according to the excitation parameters of the management queue and the first IO queue state of the secondary state machine.

And a secondary state machine is adopted to independently realize state conversion in the IO queue creating process and record the current state in the IO queue creating process.

In the above embodiment, the current state created by the management queue and the current state created by the IO queue are respectively recorded by setting a multi-stage state machine, the same state transition table is used by the first-stage state machine and the second-stage state machine, the implementation manner is simple, and in the later maintenance, the application of a new scene can be implemented by only adding elements to one state transition table.

In the RDMA transmission technology, two phases of connection establishment include a protocol layer establishment phase and a CM establishment phase performed before the protocol layer establishment phase, where the CM establishment phase is used to parse IP, route, initiate a connection request, and the like, so as to establish RDMA transmission, and the existing CM establishment phase is implemented by using traditional code writing.

In one embodiment, a state machine is employed to implement state transitions in the CM setup phase.

Before obtaining the excitation parameters of the management queue, the method further comprises the following steps:

acquiring an excitation parameter established by management;

and executing the management establishment operation instruction to realize management establishment and converting the first management establishment state of the state machine into a second management establishment state.

In the above embodiment, the state transition table of the state machine further includes a row element representing the current management setup state and different scenarios (i.e. obtained excitation parameters of different management setups) occurring in the management setup stage, and the rows and the columns jointly determine a structure array, where the elements of the structure array include: the next management setup state to jump (i.e., the second management setup state) and the management setup operation instructions needed to implement the state jump.

In the above embodiment, the state machine completes the state transition in the CM establishment phase, and thus effective control of the complex connection scene can be realized.

In one embodiment, the state machine includes a first state machine and a second state machine, the first state machine and the second state machine are respectively used for creating a management queue and an IO queue, the first state machine and the second state machine perform state conversion in a CM establishment phase at the same time, and management establishment operations such as analyzing IP, routing and initiating a connection request are performed before the management queue and the IO queue are created to establish RDMA transmission.

Referring to fig. 4, in one embodiment, the CM establishment phase is shifted from the initial state (CONN _ FREE) to the ESTABLISHED state (ESTABLISHED) state, and a plurality of management establishment operation commands are executed to complete a plurality of state shifts.

Illustratively, in fig. 4, in the initial state (CONN _ FREE), when a stimulus parameter (RESOLVE _ ADDR, RESOLVE target IP request) is obtained, the connection manager performs corresponding operations, RESOLVEs the target IP, and checks whether the network is clear, and jumps to the next management establishment state: the address is RESOLVED (ADDR _ RESOLVED).

Taking the ADDR _ RESOLVED state as a new first management establishing state, and when acquiring a new excitation parameter, RESOLVE _ ROUTE (analyzing a ROUTE request), the connection manager executes corresponding operations, analyzes the ROUTE, and checks whether the ROUTE is problematic, and jumps to the next management establishing state: ROUTE _ RESOLVED (ROUTE RESOLVED).

According to the above flow, the state machine sequentially acquires excitation parameters CONNECT (request connection), CONN _ ESTABLISHED (connection establishment), and sequentially jumps to the CONNECTING state and the CONNECTED state.

It should be noted that upon receiving the CONN ESTABLISHED excitation parameter, the CM setup phase is complete and ready for subsequent issuance of commands.

As shown in fig. 5, in one embodiment, the STATE machine (including the primary STATE machine and the secondary STATE machine) goes through some pre-preparation STATEs, entering the transport ready STATE indicates that protocol layer establishment can be started, in some embodiments, the pre-preparation STATE can be entered by a STATE _ CONNECTED STATE jump in the CM establishment phase, in the transport ready STATE, when the STATE machine acquires the SET _ connect _ TYPE excitation parameter, it determines that the management queue is a management queue according to the message queue identifier being 1, for example, in the REPORT _ connect excitation parameter, it switches to the ADMIN _ log STATE, in this process, the primary STATE machine records the current STATE of the management queue creation, and after the management queue creation is completed, the secondary STATE machine starts to run the IO queue creation flow, for example, in the BIND _ connect excitation parameter, and switches to the IO _ connect _ BOUND STATE.

When the primary state machine enters an NVMF _ ADMIN _ CONN state, the creation of the management queue is completed, and the NVMF _ ADMIN _ CONN state is the last state of the primary state machine in a normal connection state;

when the secondary state machine enters the NVMF _ IO _ CONN state, the NVMF _ IO _ CONN state indicates that the creation and binding of the IO queue is completed and is the last state of the secondary state machine under normal connection.

In an embodiment, the determining, according to the excitation parameter and the current state, a corresponding next state and an operation instruction for implementing the next state transition from a preset state transition table further includes determining whether the obtained excitation parameter is satisfied, and if so, determining a corresponding second state and an operation instruction, completing the state transition of the state machine, and executing the operation instruction.

It will be appreciated that the state machine determines whether to perform a state jump by determining whether a condition is established.

Illustratively, in the CM establishment phase, in the CONN _ FREE state, if the obtained excitation parameter is not the resolution _ ADDR, the excitation parameter is not established, and the state machine still maintains the state.

In the protocol layer setup phase, the stage one state machine in the transport state does not transition to the ADMIN _ CONN state due to acquisition of the SET _ CONN _ TYPE (false) excitation parameter, but remains in the current state. Similarly, the secondary state machine in the transition state does not transition to the IO _ CONN state due to the acquisition of the SET _ CONN _ TYPE (true) excitation parameter.

In one embodiment of the present invention,

the determining a corresponding next state and an operation instruction for implementing the transition to the next state from a preset state transition table according to the excitation parameter and the current state further includes: judging whether the excitation parameters are abnormal types or not; if so, determining that the corresponding next state is a specific state, and the corresponding operation instruction to be executed is a specific operation instruction.

Illustratively, in fig. 4-6, each time an event of an anomaly or power failure occurs in the peer network, the connection manager may be regarded as acquiring the excitation parameter CONN _ DISCONNECT of the anomaly type, and perform a unified operation: disconnecting and destroying resources, and the state machine is converted into a specific state: DISCONNECTED. In the above embodiment, the excitation parameter CONN _ DISCONNECT may be generated passively and not controlled manually.

In one embodiment, the operation instructions encapsulated by the state transition table may further include a log of state transition, which is convenient for the administrator to maintain.

Illustratively, in one embodiment, the connection manager initiates the disconnection process by obtaining an incentive parameter for the disconnection.

Illustratively, it includes:

acquiring excitation parameters of disconnection;

and executing the disconnection instruction to complete disconnection operation and converting the second management queue state of the state machine into a third management queue state.

As shown in fig. 6, in which the excitation parameter of the disconnection can be regarded as the active excitation parameter CONN _ DISCONNECT, which is generated by the operation of the manager, the primary state machine obtains the excitation parameter CONN _ DISCONNECT in the NVMF _ ADMIN _ connect state, and converts to the ADMIN _ CONN _ DISC _ PENDING state, and the executing of the disconnection instruction includes putting the management queue aside, waiting for the completion of the disconnection of the IO queue, and then destroying the management queue resource. And the secondary state machine acquires the excitation parameter CONN _ DISCONNECT in the NVMF _ IO _ CONN state, DISCONNECTs and destroys the resource, and informs the management queue to cancel the binding relationship.

It will be appreciated that in the above embodiments, the stimulus parameters may be from the requesting end or the destination end, i.e. the event may occur at the requesting end or the destination end.
