Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Before discussing exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently, or at the same time. Furthermore, the order of the operations may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a media stream holding method according to an embodiment of the present invention. The technical scheme of the embodiment can be suitable for the situation of continuously maintaining the media stream of the security equipment. The method may be performed by a media stream holding device, which may be implemented in software and/or hardware and integrated on any electronic equipment with network communication capabilities. For example, the electronic device may be a management device deployed in each security device and configured to access the network by using a national standard protocol. As shown in fig. 1, the media stream holding method in this embodiment may include the following steps:
s110, responding to the current keep-alive request message received from the target security device, and determining whether the keep-alive parameters of the target security device are successfully migrated to the pre-deployed takeover device.
In this embodiment, fig. 2 is a schematic diagram of networking between a management device and a security device according to an embodiment of the present invention. Referring to fig. 2, comprising: the system comprises a plurality of security devices (such as IPC devices and the like) and management devices, wherein the plurality of security devices adopt national standard protocols to access the management devices in a networking mode. The networking characteristics illustrated in fig. 2 above may be analyzed from the following dimensions: national standard networking and protocol interfacing, signaling and media stream separation management, SIP protocol foundation, and other dimensions. For the national standard networking and protocol interfacing, the signaling and media streams of the national standard networking have a dependency relationship, and when the signaling processing is abnormal (such as registration and keep-alive timeout failure), the media streams are released; for the separation management of signaling and media streams, the management device and the security device respectively process the signaling and the media streams with maximum capability, and the signaling and the media streams are not interfered with each other under normal conditions. For the SIP protocol base, the value of the Contact header field filled in the keep-alive response message may be modified in substitution.
In this embodiment, referring to fig. 2, on the basis of a simple networking architecture between a management device and a security device, a takeover device for implementing a keep-alive parameter migration process is added to the scheme of the present application, so as to obtain a new networking architecture as shown in fig. 2. The hardware index of the takeover device needs to be guaranteed to be at least the same as the CPU and memory index of the management device. On the basis of the networking architecture, when the management equipment needs to be restarted by service upgrading or bad part replacement and other operations, keep-alive parameters required by the security equipment can be gradually migrated to the pre-deployed takeover equipment so as to temporarily replace the management equipment by the takeover equipment to perform national standard signaling interaction processing with each security equipment.
In this embodiment, fig. 3 is a schematic diagram of keep-alive migration of security equipment provided in the embodiment of the present invention. Referring to fig. 3, at least some security devices may continue to send keep-alive request messages, here denoted as current keep-alive request messages, to the management device while the management platform migrates keep-alive parameters of each security device to the hosting device. For example, the security device may periodically (e.g., using a preset time interval as a periodic condition) send a Message keep-alive request Message to the management device based on the SIP protocol, so that the management device performs keep-alive processing, so that the security device does not go offline. At this time, the management device may determine whether the keep-alive parameters of the target security device have been migrated to the pre-deployed takeover device at present in response to the received current keep-alive request message. Among other keep-alive parameters, the following are included, but are not limited to: the device code and keep-alive remaining timeout time of the security device.
And S120, if the keep-alive parameters of the target security equipment are determined to be successfully migrated, the current keep-alive response message carrying the IP address information of the takeover equipment is sent to the target security equipment, so that the target security equipment is indicated to send a next keep-alive request message to the takeover equipment next time.
In this embodiment, referring to fig. 3, the management device may process the current keep-alive request message sent by the target security device, and send a corresponding current keep-alive response message to the target security device, so as to implement keep-alive operation of the target security device, and avoid offline of the target security device. Wherein the current keep-alive response message can be determined in a 200OK message format in the SIP protocol. Meanwhile, as the keep-alive parameters of the target security equipment are successfully migrated to the takeover equipment, and the management equipment is about to perform operations such as service upgrading or bad part replacement, the IP address information of the takeover equipment capable of carrying out keep-alive instead of the management equipment can be carried in the current keep-alive response message sent to the target security equipment.
In this embodiment, referring to fig. 3, after receiving a current keep-alive response message corresponding to a current keep-alive request message sent by a management device, a target security device (e.g., IPC device) may determine whether the received current keep-alive message carries IP address information of a takeover device. If the IP address information of the takeover device is carried, the IP address information of the takeover device carried in the current keep-alive response message can be used as a destination of the next keep-alive request message sent by the target security device, and then the next keep-alive request message is periodically sent to the takeover device so as to realize the keep-alive of the target security device by adopting the takeover device. If the IP address information of the takeover device is not carried, the next keep-alive request message is continuously sent to the management device periodically, and keep-alive is continuously carried out through the management device.
In this embodiment, referring to fig. 3, if it is determined that the keep-alive parameters of the target security device are not successfully migrated to the pre-deployed takeover device, a current keep-alive response message that does not carry the IP address information of the takeover device is sent to the target security device, and the destination of the next keep-alive request message sent by the target security device is kept as the management device, until the management device successfully migrates the keep-alive parameters of the target security device to the pre-deployed takeover device, the destination of the next keep-alive request message sent by the target security device is changed.
In an alternative of this embodiment, fig. 4 is a schematic structural diagram of a keep-alive response message provided in an embodiment of the invention. Referring to fig. 3 and 4, sending a current keep-alive response message carrying IP address information of the takeover device to the target security device may include the following steps A1-A3:
and A1, generating an initial keep-alive response message corresponding to the received current keep-alive request message.
And A2, replacing the value of the Contact header field in the initial keep-alive response message with the IP address of the takeover device and the device code to obtain the current keep-alive response message carrying the IP address information.
And step A3, sending a current keep-alive response message carrying the IP address of the takeover device to the target security device.
In this embodiment, referring to fig. 3 and 4, for the current keep-alive request message sent by the target security device to the management device, the management device may generate corresponding initial keep-alive response information. Considering that the keep-alive parameters of the target security device have been successfully migrated to the takeover device, the target security device may choose to subsequently send a keep-alive request message to the takeover device for keep-alive. Therefore, the initial keep-alive response message cannot be simply sent to the target security keep-alive to achieve the keep-alive purpose, and the initial keep-alive response message needs to be changed to obtain the current keep-alive response message carrying the IP address information. Thus, the current keep-alive request message can be used for responding to the current keep-alive request message for keep-alive, and meanwhile, the device IP address adopted by the target security device for follow-up keep-alive is specified.
S130, controlling the pre-deployed takeover device to process the next keep-alive request message sent by the target security device so as to ensure that the media stream service of the target security device is not interrupted.
In this embodiment, referring to fig. 3, after the management device sends the current keep-alive response message carrying the IP address information of the takeover device to the target security device, the keep-alive of the target security device may be controlled to migrate from the management device to the takeover device, and the next keep-alive request message sent by the target security device is processed by the takeover device, and the next keep-alive response message is returned. In this way, the target security device can be turned to the take-over device to keep alive (that is, the take-over device processes the subsequent keep-alive request message sent by the target security device to make a keep-alive response), so that the signaling state is kept, and because the signaling and media streams between the management device and the security device are separately managed, if the signaling state is kept all the time, the target security device can be kept alive all the time, and the uninterrupted media stream service can be ensured.
By adopting the scheme, the keep-alive request response is realized by migrating the keep-alive main body from the management equipment to the takeover equipment, so that uninterrupted processing of the keep-alive request of the accessed security equipment can be ensured when various operations (such as service upgrading, bad part replacement and the like) of restarting the management equipment are executed, dependency relationship exists between the signaling and the media stream selected by combining with the national standard networking, and the monitoring of the media stream service can be realized without interruption.
On the basis of the above embodiment, optionally, the media stream holding method in this embodiment may further include the following operations: and stopping the keep-alive interaction with each security device after the keep-alive parameters of all security devices associated with the management device are monitored to migrate to the pre-deployed takeover device.
In this embodiment, referring to fig. 2 and fig. 3, after the management device migrates keep-alive parameters of all IPC security devices to the takeover device, the management device may suspend keep-alive interaction operations with each security device, and the management device performs operations such as operation and maintenance service upgrade, bad part replacement, and the like, so that the media stream service is not affected.
Fig. 5 is a flowchart of another media stream holding method provided in the embodiment of the present invention, where the technical solution of the present embodiment is further optimized based on the foregoing embodiment, and the technical solution of the present embodiment may be combined with each alternative solution in one or more foregoing embodiments. As shown in fig. 5, the media stream holding method provided in the embodiment of the present application may include the following steps:
s510, determining the security equipment to be migrated and the keep-alive parameters of the security equipment to be migrated, wherein the security equipment to be migrated and the keep-alive parameters of the security equipment to be migrated meet parameter migration conditions; wherein the keep-alive parameters include: the device encodes and keeps alive remaining timeout time.
In this embodiment, fig. 6 is a schematic diagram of migration of keep-alive parameters according to an embodiment of the invention. Referring to fig. 6, after the management device successfully registers with the takeover device, the takeover device has made keep-alive parameter migration preparation work. The number of security devices of the national standard networking to which the management device is connected is huge, and the security devices need to be periodically kept alive after the successful registration between the security devices such as IPC and the management device is considered, so that the security devices are prevented from being disconnected. For this reason, it is necessary to determine the security device to be migrated that satisfies the parameter migration condition from at least two security devices associated with the management device, so as to perform keep-alive parameter migration with respect to the security device to be migrated that satisfies the parameter migration condition.
In this embodiment, if the keep-alive remaining timeout time (kpparetime) of the security device is smaller than a preset keep-alive fixed value, the security device may be offline due to no timely keep-alive, so only the security device with the keep-alive remaining timeout time greater than the preset keep-alive fixed value satisfies the parameter migration condition. Optionally, determining the security device to be migrated that meets the parameter migration condition may include the following operations: and screening the security equipment to be migrated, which meets the parameter migration condition, from at least two security equipment associated with the management equipment according to the remaining timeout time of the keep-alive of each security equipment.
S520, the keep-alive parameters of the security equipment to be migrated are carried in the Notify message in a converging mode, and the Notify message carrying the keep-alive parameters is pushed to the takeover equipment to complete migration of at least part of the keep-alive parameters.
In this embodiment, the keep-alive parameters of the security device to be migrated, which conform to the keep-alive remaining timeout period, may be aggregated according to the number of preset parameter aggregation strips, for example, according to 10 keep-alive parameters, which are aggregated once. Furthermore, the keep-alive parameters of the security equipment to be migrated, which are converged by a preset number, are carried through the Notify message based on the SIP protocol, and then the Notify message carrying the keep-alive parameters is pushed to the takeover equipment, so that the migration work of the keep-alive parameters is realized.
In this embodiment, in addition to aggregating keep-alive parameters of the security device to be migrated, parameters required by a media monitoring service of the security device to be migrated are synchronously aggregated, for example, parameters required by the media monitoring service include, but are not limited to, the following: the service type of the media stream of the security device, the address and the port of the receiving and transmitting media stream for subsequent flow control and other parameters. Table 1 shows the case of synchronous aggregation of keep-alive parameters and parameters required for the media monitoring service.
Table 1 Convergence indication of keep-alive parameters and parameters required for media monitoring services
S530, in response to the current keep-alive request message received from the target security device, determining whether the keep-alive parameters of the target security device are successfully migrated to the pre-deployed takeover device.
S540, if the migration is determined to be successful, the current keep-alive response message carrying the IP address information of the takeover device is sent to the target security device, so as to indicate the target security device to send the next keep-alive request message to the takeover device next time.
S550, the takeover device is controlled to process the next keep-alive request message so that the media stream service of the target security device is not interrupted.
By adopting the scheme, keep-alive parameters required by security equipment can be gradually transferred to the takeover equipment, response of the keep-alive request is realized by transferring a keep-alive main body from management equipment to the takeover equipment, uninterrupted processing of the keep-alive request of the accessed security equipment can be ensured when various operations (such as service upgrading, bad part replacement and the like) of restarting the management equipment are executed, dependency relationship exists between signaling and media streams selected by combining national standard networking, and uninterrupted monitoring of media stream service can be realized.
In an alternative scheme of the embodiment, before determining whether the keep-alive parameters of the target security device are successfully migrated to the pre-deployed takeover device, the method may further include the following steps B1-B2:
and B1, transmitting a Register registration request message carrying authentication information of the management equipment to the pre-deployed takeover equipment so as to initiate registration operation to the takeover equipment again.
And step B2, receiving a registration response message which is sent by the takeover equipment and passes authentication, and establishing a monitoring registration relationship between the management equipment and the takeover equipment.
In this embodiment, fig. 7 is a schematic diagram of a connection device and a management device in establishing a monitoring registration relationship according to an embodiment of the present invention. Referring to fig. 7, the management apparatus initiates a registration request to the migration device through a Sip protocol-based Register registration request message; the takeover device returns 401 an Unauthorized (Unauthorized) response message to the management device asking the management device to initiate registration again carrying an authentication message (typically a user name, password); the management device carries authentication information and sends a Register registration request message to the takeover device again to initiate registration; the takeover device passes the authentication and returns a 200OK response message to the management device.
In this embodiment, optionally, the 200OK carries an timeout period expire=t, where T represents time consumed from the migration of the data of the security device to be migrated to the startup of the live signaling of the security device, that is, a period of time when the management device cannot provide services to the outside. Wherein T depends on the management device abnormal migration demand time, which can be determined from the measured value. If the management device does not respond back, the takeover device can still provide service to the outside.
In an alternative solution of this embodiment, after the keep-alive request message of the security device is migrated to the takeover device in the forward direction for keep-alive, the takeover device determines whether the migration timeout T is reached. And if the migration timeout T is reached at fixed time, starting reverse migration, returning application layer data such as the keep-alive parameters of the security equipment and parameters required by the media monitoring service and the like in the takeover equipment to the management equipment, and returning keep-alive signaling such as the keep-alive request message and the like of the security equipment to the management equipment, namely returning the service in the takeover equipment to the management equipment. If the timing does not reach the migration timeout T, the migration timeout T is kept unchanged.
It should be noted that, when the management device cannot respond to the reverse migration request initiated by the takeover device, for example, the management device delays the reverse migration operation according to 2 sns until the management device can normally respond in the process of operation, maintenance, upgrade and bad part replacement.
By adopting the scheme of the embodiment, the monitoring registration relationship is established between the management equipment and the takeover equipment by constructing the takeover equipment, and then the monitoring media service is ensured not to be interrupted by forward migration and back migration of application layer data (such as keep-alive parameters, parameters required by the media monitoring service and the like) and keep-alive signaling (such as keep-alive request messages) of national standard IPC.
Fig. 8 is a block diagram of a media stream holding apparatus according to an embodiment of the present invention. The technical scheme of the embodiment can be suitable for the situation of continuously maintaining the media stream of the security equipment. The apparatus may be implemented in software and/or hardware and integrated on any electronic device having network communication capabilities. For example, the electronic device may be a management device deployed in each security device and configured to access the network by using a national standard protocol.
