Abstract
The invention provides a method for an OLT (Optical Line Terminal) to quickly upgrade an ONU (Optical Network Unit). The method comprises the following steps: (1) an OLT sends a request message to an ONU to query whether the ONU supports quick transmission of an upgrade file via a data link layer protocol; (2) the ONU sends a response message to the OLT, and if the response message indicates that the ONU supports quick transmission of an upgrade file via a data link layer protocol, the OLT uses a data link layer protocol to send the fragments of an upgrade file to the ONU; (3) when the transmission of the last fragment of the upgrade file is completed, the OLT sends an end download request message to the ONU to confirm whether the transmission of the upgrade file is completed; and (4) after receiving the end download request message, the ONU checks the upgrade file received, and sends the check result to the OLT. According to the invention, the upgrade file is transmitted via the data link layer protocol instead of the original OAM protocol, the efficiency of file transmission in the process of upgrading is improved, and quick ONU upgrade is realized.
Description
Technical field
The present invention relates to EPON (the Ethernet Passive Optical Network) system in data communication field
In updating and management field of the local side apparatus (OLT) to terminal unit (ONU), it is fast more particularly, to ONU in a kind of EPON system
The method of speed upgrading.
Background technology
Under the network environment of EPON, multiple stage EPON terminal unit can be connected under a usual EPON local side apparatus (OLT)
(ONU).And the software version of EPON terminals is that, by EPON local side remote upgrades, the terminal below EPON local sides needs to rise
During level, upgrade file is sent to ONU by OLT by OAM from local side.Because OAM agreements are advised in IEEE 802.3ah standards
Fixed slow protocol, transfer rate specified in agreement is that 10 frames are per second, therefore transmits the upgrade file of ONU with regard to special using OAM
It is not slow, especially for than larger upgrade file.The upgrade file of one 8M byte, update time about 10 minutes.And one
Usually there are multiple stage (up to 64-128 platforms) ONU, the ONU under an OLT that upgraded usually to need to spend a few houres under individual OLT.Therefore
It is too slow in order to solve the problems, such as ONU upgradings, method of the needs in a kind of quick upgrading of EPON system ONU achieved above.
The content of the invention
It is an object of the invention to：For the problem that ONU upgrade techniques in existing EPON system are present, there is provided a kind of
The method that ONU quickly upgrades in EPON system, it is main in ONU fast updating methods in EPON system to be assisted using data streaming link layer
View transmission upgrade file, transmission flank speed can effectively realize the quick upgrading of ONU more than 100M bytes-per-seconds.
The goal of the invention of the present invention is achieved through the following technical solutions：
A kind of method that ONU quickly upgrades in EPON system, it is characterised in that the method comprising the steps of：
(1) OLT sends request message to ONU, to inquire about whether ONU supports quickly to transmit liter using data link layer protocol
Level file；
(2) ONU sends to OLT and replies message, if replying to support, OLT is sent using data link layer protocol to ONU
The burst of upgrade file；
(3) when the sliced transmission of last upgrade file is completed, then OLT sends to ONU and terminates download request message, with
Confirm whether upgrade file is transmitted；
(4) ONU is received after termination download request message, verifies the upgrade file for receiving, and sends check results to OLT.
As further technical scheme, by extending the report that OAM carries out the burst of non-upgrade file between OLT and ONU
The transmission of text.
Used as further technical scheme, the data field length for defining the frame of the burst of the upgrade file of transmission is 1400 words
Section.
As further technical scheme, the data field length of the frame of last burst of upgrade file be 1 byte~
1400 bytes.
Used as further technical scheme, the message format of data link layer protocol is：Purpose MAC+ source MAC+ ether words
The verification of segment type+upgrade file burst number+DATA field length+DATA field+DATA field and+message checking and.
Used as further technical scheme, when upgrade file burst number is 0, DATA field length is also 0, and this is defined as
Transmission file request.
Used as further technical scheme, the greatest length of DATA field is 1400 bytes.
Compared with prior art, the present invention is because in ONU escalation process, transmission upgrade file employs data link layer
Agreement, is not limited by OAM speed, greatly there is provided file transfer rate, realizes quick upgrade function.
Specific embodiment
Below with specific embodiment, the present invention is described in detail.
Embodiment
The present invention provides a kind of method that ONU quickly upgrades in EPON system, and its step is as follows：
1) EPON local sides judge whether terminal supports quick upgrading
OLT sends GET_Request (request message) by extension OAM message, and whether inquiry ONU supports to use Data-Link
Road layer protocol quickly transmits upgrade file, and ONU is sent GET_Response (answer message) and replied by extension OAM to OLT is
No support.The step main purpose is in order that OLT compatible original can also not supported to use data link layer protocol upgrading
ONU。
2) upgrade file is transmitted
After ONU is replied to be supported to transmit upgrade file using data link layer protocol, OLT is used data link layer protocol
The burst of upgrade file is sent, it is fixed for the efficiency of transmission of file for further improving until whole upgrade file is transmitted
The data field length of the frame of justice transmission burst is 1400 bytes (except last Frame).
Data link layer protocol message format is：Purpose MAC+ source MAC+ ether field types (0x88CC)+upgrade file
The verification of burst number+DATA field length+DATA field+DATA field and+message checking and.Wherein burst number is 0 burst table
Show transmission file request, it is 0 that burst 0 does not transmit the DATA field length of file content, i.e. burst 0.DATA field greatest length
For 1400.
3) confirm that upgrading is completed
When last upgrade file sliced transmission is completed, OLT sends End Download Request by extension OAM
Message (terminates download request message), confirms that upgrade file is transmitted.ONU is received after the message, verifies the upgrading text for receiving
Part, and send End Download Response message back file verification results by extending OAM.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, it is noted that all
Any modification, equivalent and improvement for being made within the spirit and principles in the present invention etc., should be included in the guarantor of the present invention
Within the scope of shield.
