Description
Technical Field
The invention relates to the technical field of network communication, in particular to a device and a method for dynamically adjusting a speed limit threshold value of an ONU (optical network unit) equipment port.
Background
A PON (Passive Optical Network) Passive Optical Network is a point-to-multipoint TDMA access method for Optical transmission, and can carry a broadband Network of all services. The communication in the network is composed of various application flows, and the requirements of the applications on the network service and performance are different, for example, the FTP download service wants to acquire as much bandwidth as possible, while the VOIP voice service wants to ensure as little delay and jitter as possible, the network resources are always limited, and the requirement of the service quality can be generated as long as the network resources are seized. In order to guarantee transmission bandwidth, reduce transmission delay, and reduce packet loss rate and delay jitter of data, a PON system should provide a necessary QoS mechanism. When the network is overloaded or congested, qoS of various priority services can be provided in both uplink and downlink directions according to SLA protocols, so that important services are guaranteed not to be delayed or discarded, and efficient operation of the network is guaranteed. Existing QoS mechanisms include traffic classification, priority tagging, traffic policing and scheduling, traffic shaping and traffic policing, congestion avoidance, cache management, and PONMAC control, among others.
The congestion avoidance mechanism means that when congestion occurs, queue resources are released as soon as possible by packet loss, and meanwhile, messages are not put into a high-delay queue as much as possible so as to eliminate the congestion. The common method is as follows:
1. tail discard (Tail-Drop) policy: when the message exceeds the upper limit queue length of the queue message, the system starts to discard the message after the upper limit queue length, and the algorithm does not consider the discarding level.
2. Weighted Random Early (WRED) strategy: WRED is a mechanism to handle congestion according to priority. Before the traffic is congested but exceeds the traffic threshold of the interface, dropping of data frames from the selected flow is started. The discarding can be performed according to the priority level, and the discarding can be performed according to the weight value of each priority level, so that the discarding quantity of the high-priority service can be minimized, and the QoS can be ensured.
However, in both of these methods of congestion avoidance, congestion avoidance is performed at the egress according to traffic priority information or the like after congestion occurs. When the following steps are met: 1. when a server and a common PC are hung down at the same time under different ports, priority scheduling of server flow information needs to be guaranteed; 2. when the internet bar distinguishes the common users from the VIP user areas, the prior scheme can not meet the requirements when the data information of the VIP user channel is preferentially ensured to be preferentially transmitted and the like.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
Fig. 1 is a schematic structural diagram of an apparatus for dynamically adjusting a speed-limiting threshold of an ONU device port according to the present invention, and as shown in fig. 1, the apparatus for dynamically adjusting a speed-limiting threshold of an ONU device port of the present invention includes a traffic real-time monitoring and counting module 101, a traffic comparison and calculation module 102, a speed-limiting threshold dynamic adjustment module 103, an ingress port 104, a cache management module 105, a traffic supervision and scheduling module 106, a PONMAC control module 107, and a CPU108, wherein,
the real-time traffic monitoring and statistics module 101 obtains bandwidth information issued by the OLT and traffic information sent to the PON port by each port of the ingress port 104 before speed limiting, sets a priority and a weight value of each port of the ingress port 104, and positively correlates the priority level and the weight value. The bandwidth information includes a traffic channel and a bandwidth length.
For example, the ports may be set to 4 priorities, P1, P2, P3, P4, P1> P2> P3> P4, and the associated weight values are 0.8 (P1), 0.7 (P2), 0.6 (P3), and no weight value is set in the P4 priority. The weight value is the weight value corresponding to the port with the highest priority, namely the weight value is set to be 0.8 under the condition that the port with the P1 priority exists; the value is set to 0.7 when no P1 has a P2 priority port, and to 0.6 when no P1 and P2 has a P3 priority port. The same priority ports compete fairly according to the size of the port traffic.
And a traffic comparison and calculation module 102, configured to determine whether port speed limitation is required according to the acquired bandwidth information and traffic information, and calculate a speed limit threshold for each port entering or exiting the port 104 according to the priority information, the weight value, and the size of the bandwidth in the case of speed limitation.
After comparing the traffic information and the bandwidth length, the traffic comparison calculation module 102 of the present invention determines that the port speed limit needs to be adjusted when the bandwidth is smaller than the total traffic of the ports, and sets the speed limit threshold of each port according to the priority, the traffic and the weight value of each port.
And according to the sequence of the priority levels P1-P4, counting the total traffic information of the port with the highest priority level at present. And calculating the size of the current unallocated bandwidth multiplied by the weight value, and comparing the calculated size with the counted port flow. If the port flow is larger than the current unallocated bandwidth multiplied by the weighted value, the required port flow cannot pass through completely, speed limitation is required, and the speed limiting threshold is the current unallocated bandwidth multiplied by the weighted value; otherwise, it is indicated that the port traffic can completely pass under the priority, and the speed limit threshold is set to the port traffic.
And a speed limit threshold dynamic adjustment module 103, which calculates speed limit thresholds of the ports of the ingress and egress ports 104 according to the flow comparison calculation module 102, and dynamically adjusts the speed limit values of the ports of the ingress and egress ports 104.
Fig. 2 is a flowchart of a method for dynamically adjusting a speed-limiting threshold of an ONU device port according to the present invention, and the method for dynamically adjusting a speed-limiting threshold of an ONU device port according to the present invention will be described in detail with reference to fig. 2.
First, in step 201, a maximum speed limit threshold is configured for the ingress port 104, and the priority and the weight value of each port are set according to the requirement.
The weighted value is used for setting the maximum proportion of the port occupying the current residual bandwidth when the rate of the single port exceeds the bandwidth, the weighted value is associated with the priority, and the priority is positively associated with the weighted value.
The priority level of each port is set to be the same. The 4 priorities are set, P1, P2, P3, P4, P1> P2> P3> P4, the associated weight values are 0.8 (P1), 0.7 (P2), 0.6 (P3) in sequence, and the P4 priority is not provided with a weight value. The weight value is the weight value corresponding to the port with the highest priority, namely the weight value is set to be 0.8 under the condition that the port with the P1 priority exists; the value is set to 0.7 when no P1 has a P2 priority port, and to 0.6 when no P1 and P2 has a P3 priority port. The same priority ports compete fairly according to the size of the port traffic.
In step 202, the traffic real-time monitoring and counting module 101 monitors bandwidth information sent by the OLT in real time and receives traffic information sent to each of the ports 104 in real time.
In this step, after the ONU completes registration, the ONU obtains a channel configuration issued by the OLT through an Operation Management Control Interface (OMCI). The traffic real-time monitoring and counting module 101 obtains bandwidth information (service channel and bandwidth length) issued by the OLT in real time, and traffic information (traffic size) sent by each port to the PON port.
In step 203, the traffic real-time monitoring and counting module 101 sends the port traffic information, the priority, and the bandwidth information to the traffic comparison and calculation module 102, and the traffic comparison and calculation module 102 compares the obtained port traffic information and the obtained bandwidth information to determine whether speed limit adjustment is required. When the bandwidth size is smaller than the total flow of the ports, the port speed limit needs to be adjusted, step 204 is entered, otherwise, the port speed limit threshold is restored to the maximum (i.e. no speed limit).
In step 204, a speed limit threshold of each port is set according to the priority, the flow and the weight value of each port.
In this step, the total traffic information of the port with the highest priority at present is counted according to the sequence of the priorities P1-P4. And calculating the size of the current unallocated bandwidth multiplied by the weight value, and comparing the calculated size with the counted port flow. If the port flow is larger than the current unallocated bandwidth multiplied by the weighted value, the required port flow cannot pass through completely, speed limitation is required, and the speed limiting threshold is the current unallocated bandwidth multiplied by the weighted value; otherwise, it is indicated that the port traffic can completely pass under the priority, and the speed limit threshold is set as the port traffic. For example:
the currently allocated bandwidth is 2M, the total flow of the uplink ports is 4M, the port flow with the priority P1 is 1.5M, the weight value should be set to 0.8 at this time, the size of the bandwidth pre-allocated preferentially is 2 × 0.8=1.6M, which is greater than 1.5M required by the port, so the port flow can completely pass through, and the port speed limit threshold is set to 1.5M; under the same bandwidth flow, there are no ports with priority P1 but with priority P2, the flow of the ports with priority P2 is 1.5M, at this time, the weight value should be set to 0.7, the size of the bandwidth pre-allocated preferentially is 2 × 0.7=1.4M, which is less than 1.5M required by the ports, therefore, the port flow cannot completely pass through, the speed limit setting needs to be performed, and at this time, the port speed limit threshold needs to be set to 1.4M.
And setting speed limit threshold values for all the ports in sequence, and directly distributing the residual bandwidth to the current port without calculating a weight value until the current residual unallocated port is the port with the lowest priority. When the priorities of all ports are the same, the speed limit of all ports is the same as the speed limit of the common ports, and the speed limit threshold is set according to the flow proportion of the ports.
In step 205, the calculated speed limit threshold information of each port is sent to the dynamic speed limit threshold adjustment module 103, and the dynamic speed limit threshold adjustment module 103 performs uniform distribution adjustment on all ports according to the current speed limit threshold value, so as to achieve the effect of dynamic adjustment.
The device for dynamically adjusting the speed limit threshold value of the port of the ONU equipment is arranged at the inlet port of the ONU equipment, and the traffic real-time monitoring and counting module 101 acquires bandwidth information issued by an OLT (optical line terminal), monitors traffic information of each port of the inlet port of the ONU equipment, and sets priority and weight value; the traffic comparison calculation module 102 judges whether port speed limitation is required according to the acquired bandwidth information and traffic information, and under the condition that speed limitation is required, calculates speed limitation threshold values of all ports entering and exiting the ports 104 according to priority information, weight values and bandwidth sizes; the speed limit threshold dynamic adjustment module 103 dynamically adjusts the speed limit value of each port of the ingress port 104 according to the calculated speed limit threshold of each port of the ingress port 104, so as to ensure the maximum priority scheduling of the high-priority port service.
Those of ordinary skill in the art will understand that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention.
