The deployment of fast new business.
Brief description
Fig. 1 is the flow chart of the terminal system upgrade method of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the above-mentioned He other technical characteristic of the present invention and advantage are clearly and completely described,
Obviously, described embodiment is only the section Example of the present invention, rather than whole embodiments.
Terminal system includes front-end server, 10g bandwidth fiber optic, 10g optical module receptor, optical network unit (onu), end
Set top box.Wherein terminal system upgrading image file is divided into use according to the form that agreement specifies by the responsible of front-end server
User data datagram protocol bag (abbreviation udp bag), mainly fills phase to the data segment portion of UDP bag according to agreement
Answer data, and broadcast away by 10g bandwidth fiber optic in broadcast/group broadcast mode；10g optical module receptor and optical network unit
Play optical signal transduction；Terminal set top box is responsible for receive user datagram protocol bag, and verifies and reassemble into complete upgrading and reflect
As file, for terminal set top box upgrading.
As shown in figure 1, a kind of terminal system upgrade method, comprise the steps:
Image file of upgrading is divided into UDP bag according to agreement by s100: front-end server；
S101: packet will be notified by 10g bandwidth fiber optic and UDP bag broadcast or multicast mode under
It is sent to terminal set top box；
S102: according to the ip address and the port numbers that notify packet to obtain upgrading channel；
S103: monitor the port getting receive user datagram protocol bag；
S104: the UDP receiving bag is reassembled into upgrading image file；
S105: completion system upgrading after verification.
In 10g optical-fibre channel, upgrading image file is broadcast using broadcast or multicast mode and not only significantly reduce front end clothes
The load of business device, and the receptions speed of receiving terminal also improves a lot than the upgrading mode of conventional transmission streaming, broadcasting and TV fortune
Battalion business therefore not only can improve Consumer's Experience moreover it is possible to improve its competitiveness under integration of three networks overall situation.
First, front-end server, according to the port pre-defining, notifies packet by 10g bandwidth optical fibre broadcast, should
Data packet format is notified to be defined as follows:
Table 1
When wherein " identifier " field is " upgrade notification ", " data " field is used for description upgrading descriptor.Upgrading description
Symbol form is defined as follows:
Table 2
" the ip address " and " port numbers " for broadcasting upgrading image file, terminal set top box is contained in upgrading descriptor
Begin listening for this port after receiving the ip address for upgrading and port numbers, and immediately begin to receive user datagram protocol
Bag.The form definition of UDP bag is identical with table 1, differs only in, and now " data " field in table is upgrading
Data after image file segmentation.In order to ensure the integrity of terminal data, increased crc check field in packet afterbody,
Validity check to be carried out to the packet that each receives it is ensured that complete receive whole image file of upgrading.
During front-end server broadcast upgrading image file, circulation is taken to broadcast mechanism, to avoid UDP bag
Packet loss in transmitting procedure, causes terminal set top box cannot receive complete upgrading image file so that system upgrade fails.
Image file of upgrading is divided into specifically comprising the following steps that of UDP bag according to agreement by front-end server
Upgrading image file is divided into UDP bag by certain rule, mainly to unique user datagram protocol bag
Data segment is split, its composition include version number, identifier, current sequence number, last sequence number, fixed data length, reserved bit,
Data length, data and check field；Wherein data is the upgrading image file data after segmentation, and check field is to improve number
According to integrity.The beneficial effect of this step be terminal set top box according to this regular receive user datagram protocol bag after, permissible
Simply and effectively realize data acquisition and verification.
Obtain after UDP bag is reassembled into upgrading image file and system upgrade is carried out to terminal set top box
Specifically comprise the following steps that according to notifying packet to obtain the ip address of upgrading channel and port numbers；Monitor the port getting simultaneously
Receive user datagram protocol bag；The UDP receiving bag is reassembled into upgrading image file；To combination
Upgrading image file afterwards carries out the whether complete verification of file；If file is complete, system upgrade is carried out to terminal set top box.
Wherein, as follows according to the method for the ip address notifying packet acquisition upgrading channel and port numbers: in terminal system
The port of a fixation after startup is monitored；Get the notice packet defining；Parsing obtains the ip of upgrading channel
Address and its port numbers, ip address is broadcast address or multicast address.The beneficial effect of the method is that operator can be in front end
Server can flexible arrangement upgrading channel and port numbers, accomplish making full use of of resource.
Receive the speed of upgrading image file for increasing terminal, terminal set top box obtains after the port numbers of upgrading channel immediately
This port is begun listening for, and immediately treats the first UDP bag receiving, now need not judge this data
Whether bag is first packet of upgrading image file, and this UDP bag is verified, if verifying successfully,
Current sequence number according to UDP bag and last sequence number, calculate the upgrading image file size of reality, and create
Build correspondingly sized empty file, by phase in the upgrading image file data division write empty file in this UDP bag
The position answered；If verifying unsuccessfully, abandoning this UDP bag, and recording the sequence of this UDP bag
Number, in case again receiving the packet of this damage；The UDP Bao Jun of receipt of subsequent is carried out by above-mentioned steps
Process.During receiving, also go up a UDP bag sequence number and currently received User Datagram Protocol
View bag sequence number, for whether continuously judging two, if discontinuously, the sequence number of record vacancy UDP bag, in case
Again receive.Receive upgrading image file using this method can avoid causing packet loss to make to upgrade because of udp transmission mechanism
The situation of failure is it is ensured that upgrade successfully.
After being properly received whole upgrading image file, you can using the upgrading mode completion system upgrading locally commonly used.
Particular embodiments described above, has been carried out further to the purpose of the present invention, technical scheme and beneficial effect
Describe in detail it will be appreciated that the foregoing is only the specific embodiment of the present invention, the protection being not intended to limit the present invention
Scope.Particularly point out, to those skilled in the art, all within the spirit and principles in the present invention, done any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
