Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, as will be appreciated by those of ordinary skill in the art, in the various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present application, and the embodiments may be mutually combined and referred to without contradiction.
One embodiment of the present application relates to an authentication method of an optical network unit, which is applied to a mini OLT optical line terminal in an FTTR scene, as shown in fig. 1, and includes:
In an example implementation, when the optical network unit ONU is operating in a ranging state, the mini OLT may send a ranging request to each ONU, and when the mini OLT sends the ranging request, the mini OLT records a sending time of the ranging request, and when each ONU receives the ranging request sent by the mini OLT, records a receiving time of the ranging request, and returns the receiving time as a response of the ranging request to the mini OLT, where the mini OLT obtains a communication distance between each ONU and the mini OLT according to a difference between the receiving time and the sending time returned by each ONU and a transmission speed requested in a unit time.
In an example implementation, when the optical network unit ONU is in operation and in a ranging state, the mini OLT may send a ranging request to each ONU, where the ranging request may carry the sending time of the ranging request of the mini OLT; after each ONU receives a ranging request sent by a mini OLT, recording the receiving time of the received ranging request, and acquiring the communication distance between each ONU and the mini OLT according to the difference value of the receiving time and the sending time and the transmission speed requested in unit time; after each ONU obtains the communication distance, the communication distance is returned to the mini OLT.
In an example implementation, after the communication distances of the ONUs communicating with the mini OLT are acquired, the communication distances are ordered in a descending order, and the maximum communication distance in the communication distances is taken as a target communication distance; and then determining the windowing time length according to the target communication distance based on the proportional relation between the preset communication distance and the windowing time length. The proportional relationship between the communication distance and the window time length can be: the transmission distance of the optical fiber in the home should not exceed 1 km in theory, and the average division can be performed according to the window duration of 200 mus required for 20 km, so that the window duration of 10 mus (time/distance) is required for 1 km on average.
In an example implementation, the maximum communication distance between each ONU in communication with the mini OLT may also be a preset value (e.g., the preset maximum communication distance may be 20 km), and if the mini OLT monitors that there is a preset maximum communication distance value, it is not necessary to measure the communication distance between each ONU.
In an example implementation, the mini OLT may be applied in a variety of environments, and prior to implementing the methods presented herein, the network environment in which the mini OLT operates may be validated; confirming whether the mini OLT operates in an operating environment such as/XGSPON, NGPON2, 50G PON or 100G PON; as shown in fig. 2, a schematic diagram of an ONU under a mini OLT in three network environments of XGSPON, NGPON2 and 100G PON is given.
And step 102, opening a silence window of the mini OLT according to the window opening time length, and issuing an authentication request to each ONU.
In an example implementation, as shown in fig. 3, when the window is opened, the silence window refers to that the mini OLT does not provide any bandwidth resource except for the transmission resource required by the ONU to report the serial number information, so that other devices hung under the mini OLT cannot transmit information through the opened window, and the window is only used for each ONU to perform authentication and online; if the window duration is 200 mus, then 200 mus does not provide bandwidth resources in the window.
In an example implementation, after opening the silence window, the mini OLT may issue an authentication request to each ONU through the silence window, where the authentication request is effective to enable each ONU to report Serial Number (SN) information in the silence window after receiving the authentication request.
And step 103, receiving serial number information reported by each ONU according to the authentication request in the silence window, and finishing the authentication of each ONU.
In an example implementation, after receiving an authentication request issued by the mini OLT, each ONU may report a serialization request within a window-opening duration of the silence window, and if the mini OLT may receive the serial number information reported by the ONU within the period of time that the silence window is opened, consider that the authentication of the ONU reporting the serial number information has passed, and the ONU has been online; wherein the serialization request is a unique identity of each ONU.
In this embodiment, in the authentication process of the optical network units, the window duration of the mini OLT is determined according to the communication distance between each optical network unit ONU that communicates with the mini OLT, where the mini OLT is an ONU with an OLT portion function; opening a silence window of the mini OLT according to the window opening time length, and issuing an authentication request to each ONU; and in the silence window, receiving serial number information reported by each ONU according to the authentication request, and finishing the authentication of each ONU. The window opening time of the OLT is determined according to the communication distance of the ONU, so that the time for opening the silence window by the OLT is matched with each ONU, the time for authenticating each ONU to be on line is shortened, and the waste of OLT bandwidth resources caused by the overlong time for opening the silence window by the OLT is avoided.
An embodiment of the present application relates to an authentication method of an optical network unit, which is applied to a mini OLT optical line terminal in an FTTR scene, as shown in fig. 4, and includes:
in step 201, a window duration of the mini OLT is determined according to a communication distance between each optical network unit ONU in communication with the mini OLT, where the mini OLT is an ONU with an OLT portion function.
In an example implementation, the step is substantially the same as step 101 in the embodiment of the present application, and is not described here in detail.
And step 202, opening a silence window of the mini OLT according to the window opening time length, and issuing an authentication request to each ONU.
In an example implementation, the step is substantially the same as step 102 in the embodiment of the present application, and is not described here in detail.
In an example implementation, the maximum random delay of the mini OLT is 48 μs, and in theory, the random delay of 48 μs may satisfy registration of 254 ONUs, the random delay of 1 ONU on average is about 189ns, and considering the processing delay of other hardware, the single ONU delay may be set to 1 μs. After the single ONU time delay is determined, the mini OLT can determine the random time delay sent to each ONU according to the number of all the ONUs communicating with the mini OLT, for example, the number of all the ONUs is 10; the random delay issued by the mini OLT to each ONU is 10 μs. The random delay issued by the mini OLT to each ONU is issued by a physical layer operation administration maintenance message (Physical Layer Operations Administration and Maintenace, abbreviated as PLOAM).
In an example implementation, if the mini OLT issues a random time delay to each ONU, when sequence number information reported by each ONU is received in a silence window, the sequence number information reported by each ONU carries the random time delay corresponding to each ONU, so as to avoid collision or collision of the sequence number information reported by multiple ONUs, and ensure stability of reporting the sequence number information of each ONU; if the mini OLT can receive the serial number information reported by the ONU in the silence window, the ONU reporting the serial number information is considered to pass the authentication, and the ONU is online; wherein the serialization request is a unique identity of each ONU.
The implementation manner of the method and the device can be combined with shortening random time delay of each ONU on the basis of shortening windowing time on the basis of other embodiments, so that the authentication line-up speed of each ONU is further increased.
An embodiment of the present application relates to an authentication method of an optical network unit, which is applied to a mini OLT optical line terminal in an FTTR scene, as shown in fig. 5, and includes:
In an example implementation, the preset window duration may be determined according to a communication distance of each ONU in communication with the mini OLT, and after the mini OLT opens the window according to the window duration, an authentication request is issued to each ONU in communication with the mini OLT within the window.
In an example implementation, when the window is opened, the mini OLT may not provide any bandwidth resource except for transmission resources required by the ONU to report the serial number information, so that other devices under the mini OLT cannot transmit information in the period of time that the window is opened, and the window is only used for a silence window that each ONU performs authentication and online; and when the window is opened, the mini OLT can provide any bandwidth resource except the transmission resource required by the ONU to report the serial number information, so that other devices hung under the mini OLT can transmit information in the period of time when the window is opened.
In an example implementation, as shown in fig. 6, the maximum random delay of the mini OLT is 48 μs, and theoretically, the random delay of 48 μs may satisfy registration of 254 ONUs, the random delay of 1 ONU on average is about 189ns, and considering the processing delay of other hardware, the single ONU delay may be set to 1 μs. After the single ONU time delay is determined, the mini OLT can determine the random time delay sent to each ONU according to the number of all the ONUs communicating with the mini OLT, for example, the number of all the ONUs is 10; the random delay issued by the mini OLT to each ONU is 10 μs. The random delay issued by the mini OLT to each ONU is issued by a physical layer operation administration maintenance message (Physical Layer Operations Administration and Maintenace, abbreviated as PLOAM).
In an example implementation, when the mini OLT issues random time delay to each ONU, and receives serial number information reported by each ONU in a window, the serial number information reported by each ONU includes the random time delay corresponding to each ONU, so as to avoid collision or collision of the serial number information reported by multiple ONUs, and ensure stability of reporting serial number information of each ONU; if the mini OLT can receive the serial number information reported by the ONU in the window, the ONU reporting the serial number information is considered to pass the authentication, and the ONU is online; wherein the serialization request is a unique identity of each ONU.
In this embodiment, during the authentication of the optical network units, a window of a mini OLT is opened according to a preset window duration, and an authentication request is issued to each optical network unit ONU in communication with the mini OLT, where the mini OLT is an ONU with an OLT portion function; based on preset single ONU time delay, determining random time delay of each ONU according to the number of each ONU, and issuing the random time delay to each ONU through a physical layer operation management maintenance message; and in the window, receiving serial number information reported by each ONU according to the authentication request, and finishing authentication of each ONU, wherein the serial number information carries random time delay. The maximum random time delay of the ONU is determined according to the number of the ONU, so that the online time of authentication of each ONU is shortened, and the waste of OLT bandwidth resources caused by overlong time for opening a silence window by the OLT is avoided.
The above embodiments of the method may be applied to other types of optical line terminals OLT besides mini-optical line terminals OLT.
