Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of each embodiment of the present application will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in 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.
An embodiment of the present application relates to a method for scheduling a message, including: screening a first message from the designated port from the received messages according to a preset first filtering rule; wherein the first filtering rule includes a designated port; placing the first message into a first queue with highest priority on the bridge side, and placing the non-first message in the received message into other queues except the first queue on the bridge side; carrying out first multilevel scheduling on the messages in each queue of the network bridge side, and transmitting the messages to each transmission queue of the transmission port side; the message in each sending queue is sent, so that the problem of network congestion frequently occurs under the condition of limited network bandwidth is solved, the network service quality is further enhanced, and the user experience is improved.
The router in the embodiment of the application comprises: the device comprises a receiving module, a network bridge module, a filtering module, a routing module and a sending module. The receiving module is mainly used for receiving the traffic collection of the user end, the collected traffic is converged to the network bridge module, and the message of the designated port can be filtered out through the filtering module, so that the first Qos scheduling is implemented on the message at the network bridge; the message passing through the network bridge is forwarded to the sending module by the routing module, and the message can be enqueued to the wan network card corresponding to the sending module after reaching the sending module, wherein the message with the appointed port is subjected to secondary Qos scheduling, and the message after the secondary scheduling can be sent to the Internet network in one step more quickly.
The scheduling method of the message provided by the embodiment of the application is divided into two parts, wherein one part is a network port slice, and after Ethernet, 2.4G and 5G accesses are converged to a network bridge, data traffic of different network ports can be filtered out by using an Iptables tool based on a kernel Netfilter framework. The other part is secondary scheduling of messages, and when the network is in use in a peak period, namely network congestion, the data messages of the designated slice ports are accelerated secondarily through Qos strategies deployed to the equipment in advance.
The system structure diagram of the embodiment of the application is shown in fig. 1, and mainly comprises a receiving module, a network bridge module, a routing module and a sending module. The receiving module comprises an Ethernet receiving module, a WiFi 2.4G module and a WiFi 5G module; the bridge module br-lan includes a packet filter module, N queues and schedulers, and the transmission module wan includes a filter module, N queues and schedulers S109.
The receiving module is connected with the client equipment such as the Internet equipment of PC, mobile phone and the like through the Ethernet receiving module, the WiFi 2.4G module and the 5G module, and the network bridge module distributes ip addresses for the connected equipment for the equipment to use on the Internet.
After receiving the service messages, the bridge module br-lan gathers all the messages onto the bridge, and then the messages pass through the packet filter module to screen out the messages of the designated network port slice, mark the messages, map the marked messages into the first queue of the high priority queue, and flow the unmarked messages into other queues, such as the second/third/fourth queues. When the network is congested, the scheduler is used for scheduling the messages in the queues, wherein the messages in the first queue are scheduled out of the packets in priority, and the messages in other queues are scheduled according to the priority after the scheduling of the messages in the first queue is completed.
The implementation details of the method in this embodiment are specifically described below, and the following is only for facilitating understanding of the implementation details of this embodiment, and is not necessary for implementing this embodiment. The specific flow is shown in fig. 2, and may include the following steps:
in step 201, a first message from a designated port is screened from received messages according to a preset first filtering rule; wherein the first filtering rule includes the specified port.
In one example, a filtering rule is deployed for the device in advance according to a service requirement, that is, a first message from a designated port is preferentially scheduled, and when a router receives a large number of messages to be forwarded, the first message from the designated port is screened out from the large number of messages according to a preset filtering rule.
In step 202, a first message is placed in a first queue with the highest priority on the bridge side, and a non-first message in the received message is placed in other queues on the bridge side except the first queue.
In addition, after the router screens out the first message from the designated port, the first message is marked.
In one example, the first message selected from the designated port is marked, so that the first message can be identified in the subsequent step, the marked first message is mapped to the first queue with the highest priority, and the unmarked message is mapped to other queues with the priority lower than that of the first queue according to the priority.
In step 203, the first multi-level scheduling is performed on the packets in each queue on the bridge side, and the packets are transmitted to each transmit queue on the transmit port side.
In one example, the scheduler is configured to schedule with strict priority, when the network is congested, the packets in the first queue will be scheduled out of the packets preferentially, and if there is a packet to be sent in the first queue, then the other queues will not schedule the packets until the packet in the first queue is sent out. And the other queues schedule and transmit the messages in the other queues to each sending queue of the sending port according to the priority.
Further, before each queue of the bridge side is subjected to first multi-level scheduling and is transmitted to each transmission queue of the transmission port side, whether the current message subjected to first multi-level scheduling is a message to be transmitted to the transmission port or not is detected according to the routing table information; under the condition that the message to be transmitted to the transmitting port is determined, executing to put the message subjected to the first multi-stage scheduling into each transmitting queue at the transmitting port side according to a preset second filtering rule; and transmitting the current message subjected to the first multi-level scheduling to an upper application under the condition that the message is not determined to be the message to be transmitted to the sending port.
In one example, a message scheduled out of a queue needs to check routing table information, whether the message needs to be forwarded or not is judged according to the routing table information, and if the message needs to be forwarded, the message is transmitted to each sending queue of a sending side port; if the message does not need to be forwarded, the message which is dispatched to the queue is directly transmitted to an upper layer application.
Further, the first filtering rule on the bridge side and the second filtering rule on the transmission port side are different.
In one example, a message transmitted to a transmitting port is screened out by a second filtering rule, a message of a designated port is screened out, and a mark is marked on the screened message, wherein the message screened out according to the first filtering rule is different from the message screened out according to the second filtering rule, the marked message is placed in a first queue with highest priority on the transmitting port side, and the non-marked message is placed in other queues with priority lower than that of the first queue on the transmitting port side.
In addition, the sending port side can also directly put the marked message into the first queue with the highest priority of the sending port side according to the marked mark on the network bridge side, and other messages are put into other queues with priority lower than that of the first queue.
In step 204, the messages in each transmit queue are transmitted.
Specifically, the second multi-stage scheduling is performed on the messages in each queue at the transmitting port side, and the messages are transmitted to the Internet.
In order to make the implementation process of the message scheduling method in the embodiment of the present application clearer, a specific description is made with reference to fig. 3, where the specific contents are as follows:
in step C100, the router meeting the hierarchical structure is accessed through an ethernet or WiFi 2.4G/5G mode, where the message corresponding to the ethernet port is the message that needs to be accelerated in the present scheme.
In step C101, the service data stream is filtered by a filter and labeled, and then converged at the bridge br-lan.
In step C102, the marked messages are mapped to the high-priority queues, respectively, and the unmarked messages are mapped to the queues according to the priorities.
In step C103, queues are scheduled at the bridge br-lan, the scheduler is set to strict priority scheduling, the high priority queue messages are scheduled out of the queues preferentially, the messages scheduled out of the queues need to query the routing table, and whether the messages are forwarded is judged according to the result of the routing table.
In step C104, if forwarding, a packet is sent through the formulated port according to the routing result. The message to be forwarded is sent to the network card through the wan side network card, and before reaching the network card, the message can be filtered again or the label marked in the step 302 can be directly used.
In step C105, the messages are mapped into queues, and the high priority messages are queued to the highest priority queue.
In step C106, the wan scheduler schedules the queues, the scheduler is set to strict priority scheduling, and the high priority queue messages are preferentially scheduled out of the queues, and the messages are sent to the network side.
According to the message scheduling method, the messages of the ports needing to be scheduled preferentially are designated in the first filtering rule, when a large number of messages are received at the same time, the messages needing to be scheduled preferentially are screened out of the large number of messages according to the first filtering rule and marked, the marked messages are placed into the first queue with the highest priority conveniently, the unmarked messages are placed into the queues except the first queue, then the first multi-level scheduling is carried out on the messages according to the priority of the queues, the scheduled messages are sent to the queues of the sending ports, then the second multi-level scheduling is carried out on the messages, namely, the data messages of the designated ports are accelerated by the Hqos method, qos strategies are deployed in advance, user setting is not needed, and network service quality can be guaranteed in a network peak period. The method and the device realize secondary scheduling of the message of the designated port, solve the problem that network congestion frequently occurs under the condition of limited network bandwidth, further enhance the network service quality and improve the user experience.
The above steps of the methods are divided, for clarity of description, and may be combined into one step or split into multiple steps when implemented, so long as they include the same logic relationship, and they are all within the protection scope of this patent; it is within the scope of this patent to add insignificant modifications to the algorithm or flow or introduce insignificant designs, but not to alter the core design of its algorithm and flow.

In one example, the filtering module 401 deploys a filtering rule for the device in advance according to the service requirement, that is, preferentially schedules the first packet from the designated port, and when the router receives a large number of packets to be forwarded, filters the first packet from the designated port from the large number of packets according to a preset filtering rule.
In one example, the put-in module 402 marks the first message that is screened from the designated port, facilitates the subsequent step of identifying the first message, maps the marked first message to the first queue with the highest priority, and maps the unmarked message to other queues with a lower priority than the first queue.
In one example, the first scheduling module 403 configures the scheduler to be strictly prioritized, when congestion occurs in the network, the packets in the first queue will be preferentially scheduled out, and if there is a packet to be sent in the first queue, the other queues will not schedule the packet until the packet in the first queue is sent. And the other queues schedule and transmit the messages in the other queues to each sending queue of the sending port according to the priority.
According to the message scheduling device provided by the embodiment of the application, the messages of the ports needing to be scheduled preferentially are designated in the first filtering rule, when a large number of messages are received at the same time, the messages needing to be scheduled preferentially are screened out of the large number of messages according to the first filtering rule and marked, the marked messages are placed into the first queue with the highest priority conveniently, the unmarked messages are placed into the queues except the first queue, then the first multi-level scheduling is carried out on the messages according to the priority of the queues, the scheduled messages are sent to the queues of the sending ports, then the second multi-level scheduling is carried out on the messages, namely, the data messages of the designated ports are accelerated by an Hqos method, qos strategies are deployed in advance, user setting is not needed, and network service quality can be guaranteed in a network peak period.
