Description

Registration-based information processing method and device and storage medium

Technical Field

The present invention relates to Passive Optical Network (PON) technologies, and in particular, to a method and an apparatus for processing information based on registration, and a computer-readable storage medium.

Background

With the outbreak of interactive networks and large-flow data services, users have an increasing demand for bandwidth, but due to the limitations of current materials and device technologies, the bandwidth development of the PON technology is severely restricted by the technical bottlenecks of high-speed optical modules and high-speed signal transmission, and under such a situation, the fusion of multiple technologies on the PON system becomes a shortcut for improving the flow bandwidth of the PON system.

Most of the existing PON technologies are built on a Time Division Multiple Access (TDMA) technology, Multiple types of Optical Network Unit (ONU) devices of the same type are mounted through an Optical splitter under a single-channel PON port, and the ONU devices transmit Network signals in a Time slot bandwidth allocated to the ONU devices by an Optical Line Terminal (OLT) device, so that coexistence of Multiple ONU devices is realized.

In the technical evolution process of the 100G PON, it is proposed to construct a 100G PON system by integrating Wavelength Division Multiple Access (WDMA) on the basis of a TDMA technique, that is, the 100G service traffic is distributed to 4 channels of 25G PON channels for transmission in a reasonable fragmentation manner. The up and down lines of the 4 PON channels respectively adopt different light wave bands to transmit 25G network signals to form wavelength division multiple access; and different uplink time slots are still adopted among the ONU equipment to transmit network signals, so that time division multiple access is formed. Under the service state, the 4 paths of 25G PON channels still work in a 25G rate mode independently and mutually combined work to expand the flow bandwidth. Under the network architecture, how to detect the rate of the ONU devices in the network so as to adjust the rate of the ONU devices is a problem that needs to be solved now, so that the ONU devices with multiple rates coexist in the 100G PON system.

Detailed Description

In various embodiments of the present invention, a serial number request sent by an OLT device is received, and a handshake connection with the OLT device is completed in response to the serial number request; receiving rate interaction information sent by the OLT equipment, determining the data transmission rate of the OLT equipment according to the number of rate channels receiving the rate interaction information, and sending the data transmission rate to the OLT equipment; the sent data transmission rate is used for controlling the data transmission rate of the ONU equipment by the OLT equipment; receiving a ranging request sent by the OLT equipment, responding to the ranging request, and receiving and storing the EqD time; the EqD time is used for the ONU device to send data.

The present invention will be described in further detail with reference to examples.

Fig. 1 is a flowchart illustrating a first registration-based information processing method according to an embodiment of the present invention; the method is applied to an ONU device, and as shown in FIG. 1, the method comprises the following steps:

step 101, receiving a serial number request sent by an OLT device, and responding to the serial number request to complete handshake connection with the OLT device;

specifically, the responding to the serial number request to complete the handshake connection with the OLT device includes:

determining the SN of the user; responding the serial number request and sending the SN to the OLT equipment;

receiving a product identification number (ONU _ ID) and an interface identification number (Port _ ID) sent by the OLT equipment, and finishing handshake connection; the product identification number and the interface identification number correspond to the SN.

Specifically, after receiving a serial number request sent by an OLT device, an ONU device may generate a passive optical network Transmission Convergence (XGTC, XG-PON Transmission Convergence) frame according to its SN, and send the XGTC frame to the OLT device; the frame header of the XGTC frame contains the SN of the XGTC frame; after receiving the XGTC frame, OLT equipment determines an SN, and distributes a product identification number and an interface identification number according to the SN; and the ONU equipment receives the product identification number and the interface identification number sent by the OLT equipment and completes handshake connection.

Specifically, before step 101, the method further includes:

the ONU device entering the serial number state obtains a burst parameter set and a data template specified by a template (Profile) Physical Layer Operation Administration and maintenance (Ploam) sent by the OLT device.

In the interactive process of the ONU equipment and the OLT equipment, various Ploam messages are sent according to the burst parameter set and the data template; for example, in step 101, the OLT device sends a sequence number request with a known burst parameter set in the same format as the template specified by Profile Ploam; the format of the information including SN returned by the ONU device is also the same as the template specified by Profile Ploam, i.e. the ONU device sends an XGTC frame including a SN Ploam message to the OLT device.

Here, the following description is made on the state of the ONU device, where the state of the ONU device includes:

1. initial state (O1, Initial-state): the ONU device is immediately powered on, and shifts to a standby state after receiving a Downstream (Downstream).

2. Standby state (O2, Standby-state): the ONU equipment receives the downstream and waits for receiving the network parameters; after receiving the network parameters and carrying out relevant configuration, the state of the serial number is transferred.

3. Sequence Number status (O3, Serial-Number-state): the OLT device sends a serial number request to all ONU devices in O3 state to discover the new ONU device and its SN. And after the OLT equipment discovers new ONU equipment, the ONU equipment waits for the identification number allocated by the OLT equipment, and the ONU equipment can transfer to a ranging state after obtaining the identification number.

4. Ranging state (O4, Ranging-state): different ONU equipment sends signals to the OLT equipment and should keep synchronization, so that each ONU equipment needs an EqD time, the parameter is measured in a ranging state, and the ONU equipment is transferred to a running state after receiving the EqD time.

5. Operating state (O5, Operation-state): the ONU device in this state can send upstream data and Ploam messages under the control of the OLT device. After the ranging is successful, all ONU equipment sends signals according to respective EqD time so as to keep the synchronization of the uplink frame. The signals sent by the different ONU devices will arrive at the OLT device separately, but each signal will appear exactly where it should appear in the upstream frame.

102, receiving rate interaction information sent by the OLT equipment, determining the data transmission rate of the OLT equipment according to the number of rate channels receiving the rate interaction information, and sending the data transmission rate to the OLT equipment; the sent data transmission rate is used for controlling the data transmission rate of the ONU equipment by the OLT equipment;

specifically, in step 102, determining the data transmission rate according to the number of rate channels receiving the rate interaction information includes:

Here, the first rate is smaller than the second rate, the second rate is smaller than the third rate, and the third rate is smaller than the fourth rate;

for example: the first rate may be 25G, the second rate may be 50G, the third rate may be 75G, and the fourth rate may be 100G.

The rate channel is a PON channel.

Specifically, the method comprises the following steps: in the Rate interaction stage, four Rate channels of the OLT device may broadcast a downstream Rate interaction message at the same time, where the Rate interaction message includes Rate channel data (Rate channel), which may be denoted by 1111_ 0000; and when the ONU equipment reads 1111_0000, confirming to acquire the Rate channel data. The ONU equipment determines the data transmission rate thereof, and comprises the following steps:

if only 1 speed channel of the downstream four speed channels of the ONU equipment can receive the broadcasted Rate Plam information, namely only 0 speed channel works, and no 1 speed channel, no 2 speed channel and no 3 speed channel work, the data transmission speed of the ONU equipment can be determined to be 25G, the ONU equipment responds to the upstream Rate Plam which carries the Rate channel content to be 1000-1000, wherein the 1000-1000 represents the data transmission speed of 25G;

if only 2 downstream Rate channels of the four downstream Rate channels of the ONU equipment can receive the broadcasted Rate Plam message, namely only 0 and 1 Rate channels work, and 2 and 3 Rate channels do not work, the data transmission Rate of the ONU equipment can be determined to be 50G, and the ONU equipment responds to the upstream Rate Plam carrying the Rate channel content of 1100_1100, wherein 1100_1100 represents the data transmission Rate of 50G;

if only 3 downstream Rate channels of the four downstream Rate channels of the ONU device can receive the broadcasted Rate Ploam message, that is, only the 0, 1 and 2 Rate channels work, and the 3 Rate channel does not work, it can be determined that the data transmission Rate is 75G, and respond to the upstream Rate Ploam carrying the Rate channel content 1110_1110, where 1110_1110 represents the data transmission Rate of 75G;

if the four downstream Rate channels of the ONU device are all working, it can be determined that its own data transmission Rate is 100G, and respond to the upstream Rate Ploam carrying a Rate channel content of 1111_1111, where 1111_1111 indicates the data transmission Rate of 100G. Here, the format of the Rate Ploam is the same as the template specified by the Profile Ploam.

The rate interaction between the OLT device and the ONU device is realized through step 102, the ONU device may determine that its own data transmission rate is 25G, 50G, 75G, or 100G, and send the determined data transmission rate to the OLT device, and the OLT device may control the data transmission rate of the ONU device according to the sent data transmission rate in a communication process.

103, receiving a ranging request sent by the OLT equipment, responding to the ranging request, and receiving and storing the EqD time; the EqD time is used for the ONU device to send data.

Specifically, after entering the ranging state, the ONU device only responds to the ranging request of the OLT device, i.e. only performs step 103.

Specifically, the receiving a ranging request sent by the OLT device and responding to the ranging request includes:

the ONU equipment receives a ranging request sent by the OLT equipment and generates an XGTC frame responding to the ranging request, wherein the ranging request is provided with a known burst parameter set, and the frame head of the XGTC frame contains a Registration (Rg) Plam message; sending an XGTC frame to the OLT device in response to a ranging request.

Specifically, the receiving and saving the EqD time includes:

and receiving a message (Ranging Time) with the EqD Time sent by the OLT equipment, and storing the EqD Time.

Here, the EqD time is allocated by the OLT device to the ONU device, and is used by the ONU device to send data. Specifically, the method comprises the following steps: the OLT equipment determines the data round-trip time between the OLT equipment and each ONU equipment through the ranging request and the response ranging request, and allocates an EqD time to each ONU equipment according to the difference of the data round-trip time, so that the synchronization is kept when the signals sent by each ONU equipment reach the OLT equipment.

Through step 103, ranging interaction between the OLT device and the ONU device is completed, and the ONU device enters an operating state (O5).

In this embodiment of the present invention, after receiving and storing the EqD time, the method further includes:

and 104, receiving the rate interaction information periodically sent by the OLT equipment, determining the data transmission rate of the OLT equipment according to the number of the rate channels for receiving the rate interaction information, and sending the data transmission rate.

Specifically, the receiving of the rate interaction information periodically sent by the OLT device includes:

and receiving the rate interactive information periodically broadcast by the OLT equipment through at least one rate channel.

It is ensured by step 104 that the OLT device can always determine the rate of the ONU device during subsequent communication.

Specifically, after receiving and storing the EqD time, the method further includes:

step 105, receiving information of a control rate channel sent by the OLT equipment;

and sending the adjusted data transmission rate to the OLT equipment.

Specifically, the OLT device sends information for controlling the rate channels to the ONU device, and the ONU device determines the number of the working rate channels according to the information for controlling the rate channels, so that the effect of controlling the data transmission rate of the ONU device is achieved.

On the other hand, in the communication process, when one or more damaged rate channels exist in the ONU device, the data transmission rate of the ONU device can be determined according to the existing usable rate channels.

The dynamic switching of the ONU equipment with different data transmission rates is realized by changing the number of the rate channels of the ONU equipment through the step 105, and the ONU equipment with different data transmission rates is compatibly managed.

Fig. 2 is a flowchart illustrating a second registration-based information processing method according to an embodiment of the present invention; the method is applied to the OLT device, and as shown in FIG. 2, the method comprises the following steps:

distributing a product identification number and an interface identification number for the ONU equipment according to the SN, and sending the product identification number and the interface identification number to the ONU equipment; and the product identification number and the interface identification number are uniquely corresponding to the SN.

Specifically, the OLT device receives an XGTC frame sent by the ONU device, and the frame header of the XGTC frame contains the SN of the OLT device; the OLT device extracts the SN of the ONU device from the XGCT frame; and the OLT equipment allocates a unique product identification number and an unique interface identification number to the ONU equipment as allocation information according to the SN, and sends the allocation information to the ONU equipment.

In this embodiment of the present invention, before step 201, the method further includes:

and distributing the EqD time for each ONU device according to the data round-trip time.

FIG. 3 is a schematic diagram illustrating a registration-based information processing method according to an embodiment of the present invention; as shown in fig. 3, the left side shows a process of interacting between the OLT device and the ONU device, which is specified in the ITU-T G987.3 standard protocol in the related art, and specifically includes:

the ONU device is in a standby state after being powered on (O1), and the ONU device is transferred to a standby state-serial number state after receiving a Downstream (Downstream) transmitted by the OLT device (O2-3);

in the O2-3 state, first, the ONU device receives a template (Bprofile ploam) of a burst parameter set and data, which is sent by the OLT device and is maintained by the template physical layer operation management; then, receiving a serial number Request (Sn Request) sent by the OLT equipment, and sending information (Sn ploam) carrying SN of the ONU equipment to the OLT equipment by the ONU equipment so as to respond to the serial number Request; receiving the identification number (Assign ONUid) allocated by the OLT device according to the SN of the ONU device may include: product identification number, interface identification number, etc.; after the above operation is completed, the ONU device transitions to a ranging state (O4);

in the O4 state, the ONU only responds to the ranging request of the OLT; and allocating EqD time to each ONU device through the ranging request, so that different ONU devices keep synchronization when sending signals to the OLT device. Specifically, the ONU device receives a ranging Request (Rg Request) sent by the OLT device, and receives an equalization delay time (Eqd) sent by the OLT device after responding to the ranging Request (Rg ploam). After the ranging is successful, all ONU equipment sends signals according to respective EqD time so as to keep the synchronization of the uplink frame. The signals sent by the different ONU devices will arrive at the OLT device separately, but each signal will appear exactly where it should appear in the upstream frame.

After the above operation is completed, the ONU device enters an operating state (O5).

The right side shows the process of the interaction between the OLT device and the ONU device in the embodiment of the present invention, which specifically includes:

in the O2-3 state, firstly, the ONU equipment receives the Bprofile ploam sent by the OLT equipment; then, receiving a serial number Request (Sn Request) sent by the OLT equipment, and sending information (Sn ploam) carrying SN of the ONU equipment to the OLT equipment by the ONU equipment; then receiving a product identification number (Assign ONUid) distributed by the OLT equipment according to the SN of the ONU equipment; finally, the ONU equipment receives the downlink rate ploam sent by the OLT equipment, determines the data transmission rate (Up rate ploam) of the ONU equipment according to the number of the rate channels receiving the rate interaction information, and sends the data transmission rate to the OLT equipment; after the above operation is completed, the ONU device transitions to a ranging state (O4);

in the O4 state, the ONU equipment receives a ranging Request (Rg Request) sent by the OLT equipment, and after responding to the ranging Request (Rg ploam), receives the equalization delay time (Eqd) sent by the OLT equipment; after the ranging is successful, the ONU device enters an operating state (O5).

It can be seen that, in the process of the interaction between the OLT device and the ONU device specified in the ITU-T G987.3 standard protocol in the related art shown on the left side, the OLT device and the ONU device perform serial number interaction (Sn Request → Sn Ploam → Assign ONUid) and ranging interaction (Rg Request → Rg Ploam);
