It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Fig. 1 illustrates a flow diagram of some embodiments of a method of transmission of data of the present disclosure.
As shown in fig. 1, the method includes: step 110, establishing a multicast channel; step 120, initiating signaling multicast; step 130, data multicasting is initiated.
In step 110, a signaling multicast channel and a data multicast channel are established. For example, an IP network with multicast capability may be used as a carrier for data transmission, and multiple multicast channels may be allocated in advance in the IP network for transmitting signaling and data.
In step 120, signaling multicast is initiated through the signaling multicast channel, so that each user equipment joining the signaling multicast group determines whether to join the multicast group of the data multicast corresponding to the signaling multicast according to the signaling multicast packet.
In some embodiments, a packet for data multicast is generated for a data packet to be transmitted, and a corresponding packet for signaling multicast is generated according to the data multicast to be initiated. For example, the signaling multicast packet may include an identification of the signaling multicast (CTC _ UPGRADE), an IP address of a corresponding data multicast, and a port of the corresponding data multicast.
In some embodiments, the user equipment may be a set-top box of an IPTV, and the data packet may be an upgrade packet of set-top box software. For example, the message of the signaling multicast includes the model of the user equipment (such as a set-top box) to be upgraded, the current version number of the software, the upgrade version number of the software, and whether the upgrade type is directed equipment upgrade or total equipment upgrade. And under the condition that the upgrading type is the upgrading of the directional equipment, the message of the signaling multicast also comprises an IP address field of the directional equipment.
In some embodiments, the fields and occupied bytes in the signaling multicast message are shown in table 1.
TABLE 1
| Field(s) | Occupied byte |
| Identification of signaling multicast | 16 bytes |
| Type of set-top box | 16 bytes |
| Current version number of software | 32 bytes |
| Upgrade version number of software | 32 bytes |
| MD5 of data packet | 32 bytes |
| IP address for data multicast | 16 bytes |
| |
8 bytes |
| Upgrade |
8 bytes |
| Initial IP address of device requiring upgrade | 16 bytes |
| End IP address of device requiring upgrade | 16 bytes |
In some embodiments, after the set-top box is powered on, the set-top box responds to a signaling multicast initiated by the multicast management platform, joins in a multicast group of the signaling multicast, and monitors a message of the signaling multicast. And analyzing the monitored signaling multicast message, and judging whether a corresponding multicast group of the data multicast needs to be added (for example, the judgment can be made according to information such as the device model, the software version number and the like in the signaling multicast message). Under the condition that the data needs to be added, the set-top box adds a multicast group of the data multicast; and under the condition that the addition is not needed, discarding the message of the signaling multicast.
In step 130, data multicast is initiated through the data multicast channel, so that the user equipment joining the multicast group of the data multicast obtains a data packet from the packet of the data multicast.
Therefore, the pre-allocated specific multicast channel of the IP network is used as a carrier, and the data is rapidly distributed to the network terminal in a broadcast mode, so that the network bandwidth can be effectively saved, the concurrency pressure of the server is reduced, the resource investment is saved, and the response time limit is shortened.
In some embodiments, the data packet may be split and then encapsulated, and then sent to the user equipment by means of data multicast. This may be achieved, for example, by the embodiment of fig. 2.
Fig. 2 illustrates a flow diagram of some embodiments of a packet fragmentation encapsulation method of the present disclosure.
As shown in fig. 2, the method includes: step 210, splitting a data slice; step 220, encapsulating the data multicast message.
In step 210, a data packet to be transmitted is split into a plurality of data slices.
In step 220, a plurality of data slices are encapsulated into a data multicast packet, where the data multicast packet includes splitting information of a data packet, so that the user equipment combines the plurality of data slices into the data packet according to the splitting information.
In some embodiments, multiple data slices may be encapsulated into a streaming media file as a message for data multicast. The multicast packet may include a data multicast identifier (CTC _ UPGRADE), a size of the data packet, a total number of split packets (data slices), a serial number of the split packet transmitted this time, a size of the data packet transmitted this time, and other packet split information, and actual data of each split packet. For example, the fields and bytes occupied in the data multicast message are shown in table 2.
TABLE 2
In some embodiments, the ue of the multicast group joining the data multicast may parse and combine the packets of the data multicast through the embodiment in fig. 3 to obtain the data packet.
Fig. 3 illustrates a flow diagram of some embodiments of a data packet acquisition method of the present disclosure.
As shown in fig. 3, the method includes: step 310, acquiring splitting information; at step 320, the data packets are assembled.
In step 310, the split information of the plurality of data slices and data packets is obtained from the data multicast message. For example, a packet protocol header of a data multicast may be parsed to obtain the splitting information of the data packet.
In step 320, the plurality of data slices are assembled into a data packet according to the splitting information. For example, each data slice in the message body of the data multicast may be obtained according to the splitting information, and then the data slices may be combined into a data packet.
In some embodiments, the message of the data multicast includes first summary information of the data packet, so that the user equipment verifies the data packet by comparing the first summary information with the second summary information. The second abstract information is calculated by the user equipment according to the data packet acquired from the data multicast message. For example, the user equipment may authenticate the data packet through the embodiment of fig. 4.
Fig. 4 illustrates a flow diagram of some embodiments of a data packet validation method of the present disclosure.
As shown in fig. 4, the method includes: step 410, acquiring first summary information; step 420, calculating second summary information; and step 430, verifying the data packet.
In step 410, first digest information of the data packet is obtained from the data multicast packet. For example, the first Digest information is a MD5(Message-Digest Algorithm) hash value of the data packet calculated by the platform side.
In step 420, second digest information of the data packet is calculated. For example, the second digest information is an MD5 hash value of the data packet calculated by the user equipment according to the acquired data packet.
In step 430, the data packet is verified by comparing the first digest information and the second digest information.
In some embodiments, the data package may be an upgrade package, which the user device may rename and store, e.g., as/cache/update. Then, an upgrade method of the Android system, for example, a recovery system, installpackage (File packageFile), etc. may be called to perform upgrade; in the case where the hash values of the two MDs 5 are different, the upgrade package may be deleted and the corresponding multicast group for data multicast may be exited. Therefore, the integrity and the safety of the acquired data packet can be verified simultaneously, and the reliability and the safety of the system are improved.
The data transmission method disclosed by the invention can be suitable for various services under the condition that the number of user equipment (such as set top boxes) is not limited, for example, the set top boxes for starting a batch of devices are upgraded, advertisements are pushed, and apk (Android Package) is upgraded. And under the condition that the number of the user equipment is not limited, the emergency message can be rapidly issued to a batch of started set-top boxes, or emergency event processing can be carried out on the batch of started set-top boxes.
The transmission method of the present disclosure is explained below from the user equipment side.
Fig. 5 shows a flow diagram of further embodiments of a method of transmission of data of the present disclosure.
As shown in fig. 5, the method includes: step 510, adding signaling multicast; step 520, judging whether to join data multicast; step 530, adding data multicast; step 540, receiving the data multicast message; and step 550, obtaining the data packet.
In step 510, join the multicast group of the signaling multicast initiated by the multicast management device through the signaling multicast channel established by the multicast management device.
In step 520, it is determined whether to join a multicast group of data multicast corresponding to the signaling multicast according to the signaling multicast packet received from the signaling multicast channel.
In step 530, in the case of joining the multicast group for data multicast, join the multicast group for data multicast through the data multicast channel established by the multicast management device.
In step 540, a data multicast packet is received through the data multicast channel.
In step 550, a data packet is obtained from the data multicast packet.
