Description

Method and device for executing quality of service QoS policy

technical field

The present invention relates to the field of communication technology, in particular to a method and device for executing a QoS (Quality of Service, quality of service) policy.

Background technique

QoS is a technology used to solve problems such as network delay and congestion. When network congestion occurs, data packets will be discarded. In order to meet the user's requirements for different applications and different service qualities, it is necessary to allocate and schedule resources according to the user's requirements, and provide different service qualities for different data packets. Among them, the data packets transmitted by different applications of the user are different. Prioritize the processing of important and real-time data packets; provide lower processing priority for ordinary data packets that are not real-time, and even discard them when the network is seriously congested. Therefore, different service qualities are reflected by implementing different QoS policies on network devices.

In the prior art, when a network device implements a QoS policy for an IPv6 (Internet Protocol Version 6, Internet Protocol Version 6) data packet, it first performs flow classification on the IPv6 data packet. When performing traffic classification, it is necessary to read the source address, destination address, source port number, destination port number, and transport layer protocol type in the IPv6 datagram. These five types of fields can be called quintuples. However, since the three fields of source port number, destination port number, and transport layer protocol type are located after the extensible field of the IPv6 packet header, and the extended length of the extensible field is not fixed, the position of the above three fields in the IPv6 packet header will be changed. Therefore, the efficiency of the network device in obtaining the relevant content of the above three fields is low, which affects the efficiency of flow classification, thereby affecting the efficiency of the network device in executing the corresponding QoS policy.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The embodiment of the present invention provides a method for executing a QoS policy, which can improve the efficiency of implementing a QoS policy by a router, as shown in FIG. 1 , including:

101. The router obtains the flow label in the IPv6 data packet to be sent.

Wherein, the local gateway sends the IPv6 data packet to be sent to the router. The router reads the flow label of the IPv6 data message to be sent, wherein the flow label is used to indicate the user level of the user equipment and/or the application service type to which the IPv6 data message belongs. The application service type to which the IPv6 data packet belongs is filled in the flow label by the user equipment. The user level of the user equipment is indicated by the flow label parameter, and the local gateway fills the flow label parameter into the user flow label. In FIG. 5 , the relationship between the router, the user equipment and the local gateway is described in detail, and details are not repeated here.

102. The router executes the QoS policy corresponding to the IPv6 data packet to be sent according to the flow label.

Wherein, the QoS policy includes a mapping relationship between the IPv6 data packets to be sent and the forwarding sequence of the IPv6 data packets to be sent. The mapping relationship is described in detail in step 202 and step 302, and will not be repeated here.

It should also be noted that before the router executes the QoS policy corresponding to the IPv6 data message to be sent, it needs to judge the situation of the IPv6 data message to be sent. When the IPv6 data message to be sent is a single message of different user equipment, execute Step 201 to step 202; when the IPv6 data message to be sent is a different message of the same user equipment, perform step 301 to step 302; when the IPv6 data message to be sent is a different message of different user equipment, perform step 401 Go to step 402.

A method for executing a QoS policy provided by an embodiment of the present invention obtains the flow label in the IPv6 data message to be sent, and executes the QoS policy corresponding to the IPv6 data message to be sent according to the obtained flow label. Compared with the prior art, when implementing the QoS policy, the five-tuple in the IPv6 data message must first be obtained to classify the IPv6 data message, and the network device obtains the source port number and destination port number in the five-tuple. The acquisition efficiency of the three fields of number and transport layer protocol type is low, and the flow classification efficiency is low. Therefore, the problem of low efficiency in implementing QoS policies by network devices arises. The embodiment of the present invention provides a method for a network device to execute a corresponding QoS strategy only by obtaining the flow label in the IPv6 data message to be sent, which can improve the efficiency of the router in executing the QoS strategy.

The embodiment of the present invention also provides a method for executing a QoS policy. This embodiment is applicable to the situation where the IPv6 data message to be sent is a single message of different user equipments. At this time, the flow label is used to represent the user level of the user equipment. is the flow label parameter, as shown in Figure 2, the method is executed after step 101, including:

201. The router acquires a flow label parameter in the flow label.

Wherein, the flow label parameter indicates the user level of the user equipment. The embodiment of the present invention provides a method for indicating a flow label parameter, such as "0xFF1", but the field length and specific field content of the flow label parameter are indicated, which is not limited in the present invention. User levels can be represented by Arabic numerals. For example, a user with a user level of "1" has a higher priority than a user with a user level of "2", and a user with a user level of "2" has a higher priority than a user with a user level of "3" users, and so on, can set the minimum user level according to the actual deployment situation of the operator. The embodiment of the present invention does not limit the minimum user level.

202. The router executes the QoS policy corresponding to the IPv6 data packet to be sent according to the flow label parameter and the first preset rule.

Wherein, the first preset rule represents the mapping relationship between flow label parameters and QoS policies. The mapping relationship between flow label parameters and QoS policies is shown in Table 1. Table 1 includes two types of entries of user level and flow label parameters, and the first row in Table 1 is respectively user level and flow label parameters from left to right. Through Table 1, the flow label parameters corresponding to the user level can be found one-to-one. As shown in the second line of Table 1, the user level is "1", which means that the user is a "VIP (very important people, VIP)" user, and the corresponding flow label parameter is "0xFF1"; the third line of user level is "2 ", which means that the user is a "platinum" user, and the corresponding flow label parameter is "0xFF2"; the user level in the fourth line is "3", and the corresponding flow label parameter is "0xFF3", which means that the user is a "gold" user; the fifth line The user level is "4", which means that the user is a "silver" user, and the corresponding flow label parameter is "0xFF4"; the user level in the sixth line is "5", which means that the user is a "copper" user, and the corresponding flow label parameter is " 0xFF5". In Table 1, the user levels decrease in order from top to bottom.

It should be noted that the user levels in Table 1 correspond to the QoS policies that need to be implemented by network devices, and different user levels implement different QoS policies. For example: the flow label parameters in the data packets to be transmitted of two users read by the router are 0xFF1 and 0xFF5 respectively, since the user level corresponding to 0xFF1 in Table 1 is level 1, and the user level corresponding to 0xFF5 is level 5, so , when the network load is high and the congestion is severe, if the router receives both the IPv6 data packet with the flow label parameter 0xFF1 and the IPv6 data packet with the flow label parameter 0xFF5, the router will give priority to the IPv6 data packet with high user level. to process.

Table 1

user level stream tag parameters 1(VIP) 0xFF1 2 (Platinum) 0xFF2 3 (gold) 0xFF3 4 (Silver) 0xFF4 5 (copper) 0xFF5

It should also be noted that the present invention is not limited to the five user levels shown in Table 1. There can be more and more detailed level definitions. At the same time, the length of the flow label parameter can also be changed according to the needs of the operator. If a finer level definition is required, the length of the flow label parameter can be appropriately increased.

The embodiment of the present invention also provides a method for executing a QoS policy. This embodiment is applicable when the IPv6 data message to be sent is a different message of a single user equipment. At this time, the flow label is used to indicate that the IPv6 data message belongs to The application business type is the application business type, as shown in Figure 3, the method is executed after step 101, including:

301. The router obtains the application service type in the flow label.

Wherein, each data packet to be sent has its fixed application service type. Application service types include at least: video streaming service, download service, game service, etc. The embodiment of the present invention does not limit only the above three types of application services, and other application service types except the above three types of application services can be applied to the embodiments of the present invention. For example, for a game application, the user equipment marks the application service type of the data packet to be sent sent by the application as a game type. Similarly, if it is a video application or other type of application, the data packet to be sent is marked according to the application type. The application service type is generated by the user equipment according to the application type. If the application program or the user equipment does not support it, it will be set to 0. Among them, 0 has the lowest priority.

302. The router executes the QoS policy corresponding to the IPv6 data packet to be sent according to the application service type and the second preset rule.

Wherein, the second preset rule represents the mapping relationship between the application service type and the QoS policy.

For example: the priority of video streaming service and game service is higher than that of download service. In this way, for a single user, when the network is congested, the IPv6 data packets marked as the video stream service type or the game service type will be preferentially sent.

The embodiment of the present invention also provides a method for executing a QoS policy. This embodiment is applicable when the IPv6 data packets to be sent are different packets of different user equipments. At this time, the flow label is used to indicate the user level of the user equipment. and the application service type to which the IPv6 data message belongs, the flow label is a flow label parameter and an application service type, as shown in Figure 4, the method is performed after step 101, including:

401. The router acquires a flow label parameter in a flow label, and determines a sending sequence of all packets included in the same user equipment according to the flow label parameter and a first preset rule.

For example: the router obtains all different types of IPv6 data packets to be transmitted sent by the user equipment 1 and the user equipment 2 at the same time. The router reads the flow label parameters in all different types of IPv6 data packets to be transmitted sent by user equipment 1 as "0xFF1", and reads the flow label parameters in all different types of IPv6 data packets to be transmitted sent by user equipment 2 is "0xFF2". Because in the first preset rule, the user level corresponding to "0xFF1" is level 1, and the user level corresponding to "0xFF2" is level 2, so when the network is blocked, the router will first send the flow label parameter as "0xFF1" All different types of IPv6 data packets to be transmitted, that is to say, the router will first process all different types of IPv6 data packets to be transmitted sent by the user equipment 1 . Then all different types of IPv6 data packets to be transmitted belonging to the user equipment 2 are sent.

402. The router obtains the application service type in the flow label, and determines a QoS policy corresponding to each packet included in the same user equipment according to the application service type and a second preset rule.

For example: when the priority of the video service type is higher than that of the download service type, the router acquires the IPv6 data packet 1 to be transmitted and the IPv6 data packet 2 to be transmitted sent by the same user equipment. The router reads the flow label of the IPv6 data packet 1 to be transmitted, obtains that the application service type of the IPv6 data packet 1 is a video service, reads the flow label of the data packet 2 to be transmitted, and obtains the IPv6 data packet 2 The application service type is download service. Since the priority of the video service type is higher than that of the download service type, when the router obtains the IPv6 data packet 1 to be transmitted and the IPv6 data packet 2 to be transmitted, according to the IPv6 data packet 1 to be transmitted and the IPv6 data packet to be transmitted For the application service type of IPv6 data message 2, first send the IPv6 data message 1 to be transmitted, and execute the QoS policy corresponding to the application service type of the IPv6 data message 1 to be transmitted, then send the IPv6 data message 2 to be transmitted, and execute A QoS policy corresponding to the application service type of the IPv6 data packet 2 to be transmitted.

Wherein, the first preset rule represents the mapping relationship between the flow label parameter and the sending sequence, and the second preset rule represents the mapping relationship between the application service type and the QoS policy.

It should be noted that, for different user equipments, the router performs processing according to user levels of different user equipments, and the packets to be sent sent by user equipments with higher user levels are prioritized for processing. In addition, for different types of IPv6 data packets to be sent sent by the same user equipment, the router processes according to the application service type of the IPv6 data message to be sent, and the data packets to be transmitted with higher priority of the application service type are processed first.

To facilitate the understanding of the present invention, in another embodiment of the present invention, a flow chart of another QoS policy execution method is provided, as shown in FIG. 5 . The method flow shown in Figure 5 is applied in the following implementation scenarios, which include: a user equipment, a local gateway, a DHCPv6 (Dynamic Host configuration Protocol version 6, Dynamic Host Configuration Protocol version 6) server, a router , a cache server, and, in the above scenario, the user equipment can communicate with the DHCPv6 server, the local gateway, and the cache server; the local gateway can communicate with the DHCPv6 server and the router; and the router can communicate with the cache server. In summary, the overall method process of the present invention is:

0), storing the flow label parameter, the mapping relationship between the flow label parameter and the user level, and the corresponding relationship between the user ID (Identity, identification number) and the user level in the DHCPv6 server. At the same time, the first preset rule and the second preset rule are stored on the router. In this way, when the IPv6 data message to be sent passes through the router, the router obtains the flow label parameter in the IPv6 data message to be sent, and forwards the IPv6 data message to be sent according to the QoS policy corresponding to the flow label parameter.

1) The user equipment initiates an online request to the DHCPv6 server, and the request includes the user ID.

2) The DHCPv6 server determines the user level according to the user ID in the received user online request, and sends the flow label parameters to the local gateway according to the user level.

3) The local gateway saves the flow label parameters, user local identifier, IPv6 address and DNS server address issued by the DHCPv6 server.

Among them, the user's local identifier is the user's MAC (Media Access Control, Media Access Control) address, which itself has no effect on the implementation of the QoS policy, but considering the subsequent deployment and user management-related requirements, so identifying each user is Prepare for administrative functions. The user local identifier is different from the above user ID, and the user ID is only used to indicate the user identity when sending an online request to the DHCPv6 server.

4) The local gateway configures the user equipment online, specifically configuring the user equipment with an IPv6 address and a DNS server address.

5), when the user equipment sends the IPv6 data message to be sent, it first fills in the flow label of the IPv6 data message to be sent with the application service type to which the IPv6 data message to be sent belongs locally, and then sends the IPv6 data message to be sent The text is sent to the local gateway.

6), the local gateway fills in the flow label parameter and the user local identifier issued by the DHCPv6 server into the flow label field of the IPv6 data message to be sent, and sends the IPv6 data message to be sent to the router.

7), the router receives the IPv6 data message to be sent sent by the local gateway, reads the flow label in the IPv6 data message to be sent, executes the corresponding first preset rule and the second preset rule according to the flow label, and according to The first preset rule and the second preset rule send the IPv6 data packet to be sent to the cache server.

8). The cache server exchanges data with the user equipment.
