The following provides a detailed description of examples of the present specification.
As shown in fig. 1, fig. 1 is a flowchart illustrating a bandwidth management method according to an exemplary embodiment, including the following steps:
In this embodiment, the network elements capable of supporting bandwidth management include hosts, routers, switches, and the like, and the roles of these network elements include:
allocating bandwidth channels to the messages, marking types, and providing different processing for different types of messages;
providing flow supervision and flow shaping, and limiting and adjusting the input and output speeds of the messages;
admission control is provided to determine whether messages are allowed to use network resources.
The message (message) is a data unit exchanged and transmitted in the network, and is also a unit transmitted by the network. The message contains the complete data information to be sent, and the lengths of the messages do not need to be consistent.
The message is continuously encapsulated into packets, packets and frames for transmission in the transmission process, and the encapsulation mode is to add a header consisting of some control information, namely the message header.
In this embodiment, if a forwarded message is received, Header information required for allocating a bandwidth channel may be read from a Header (Header).
And 103, distributing the message to a bandwidth channel adapted to the message header information.
In this embodiment, the bandwidth channel may refer to a virtual channel through which the message passes.
Configuring a plurality of bandwidth channels in a network, wherein each bandwidth channel can be used for transmitting different types of flow, comparing message header information of a message with the setting of the bandwidth channel, and selecting a proper virtual channel, thereby distributing the message to the proper bandwidth channel.
In one embodiment of the present invention, as shown in fig. 2, step 103 may include the following steps:
in step S11, the current system time is queried.
Step S12, if the system time is within a preset effective time, searching for a bandwidth policy that takes effect within the effective time.
In this embodiment, a plurality of bandwidth policies may be set in advance according to the service requirements, and the packet may be guaranteed or limited by referring to the bandwidth channel.
The effective time, that is, the time when the bandwidth policy is effective, can be set in each bandwidth policy.
For example, a certain bandwidth policy is to prohibit access to the shopping website, the effective time of the bandwidth policy is 8:00-18:00 of a working day, namely 8:00-18:00 of the working day, the bandwidth policy is effective, and the access to the shopping website is prohibited.
At this time, the current system time may be read, and the effective time of each bandwidth policy is traversed, and the system time is compared with each effective time.
If the current system time is within the effective time, the bandwidth strategy is effective and can be used for matching with the message header information.
If the current system time is beyond the effective time, the bandwidth strategy is not effective and is not used for matching with the message header information.
And step S13, matching the message header information with a bandwidth strategy.
Step S14, if the header information of the packet is successfully matched with the bandwidth policy, the packet is allocated to a bandwidth channel corresponding to the bandwidth policy.
In this embodiment, the header information may be matched with the bandwidth policy, and whether the header information conforms to the setting of the bandwidth policy is determined.
And if so, distributing the message to a bandwidth channel indicated by the bandwidth strategy to limit the flow.
If not, the message is distributed to the bandwidth channel without speed limit and is directly sent from the network interface.
In one embodiment, two or more bandwidth policies are preset, and each bandwidth policy may configure a corresponding priority according to the traffic demand.
In this embodiment, the header information and the bandwidth policy may be sequentially matched according to the order of priority, and until the matching is successful, the bandwidth policy with a high priority is preferentially used.
Further, for each match, the bandwidth policy with the highest priority may be selected from the currently unmatched bandwidth policies.
And judging whether the message header information is matched with the bandwidth strategy with the highest priority.
If yes, the message header information is successfully matched with the bandwidth strategy with the highest priority.
If not, returning to select the bandwidth strategy with the highest priority from the currently unmatched bandwidth strategies, namely, failing to match currently, and carrying out next matching.
In one example, the message header information includes at least one of:
source domain, destination domain, source IP address, destination IP address, source service, source user, source application.
Correspondingly, the bandwidth policy includes at least one policy parameter as follows:
a reference domain, a reference address, a reference service, a reference user, a reference application.
The reference domain belongs to a security domain and is a set of networks connected with a plurality of interfaces, and users in the networks have the same security attribute.
In a bandwidth policy, the configuration reference domain may limit traffic, for example, from Trust (trusted zone) to DMZ (demilitarized zone).
The reference address belongs to a single address, an address group or a domain name, and taking the IP address as an example, the IP address is a same address format provided by an IP protocol and is a logic address distributed to each network and each host on the Internet; a domain name is a name used to identify a computer or group of computers on a network, and may be mapped to an IP.
In the bandwidth policy, the configuration reference address may limit traffic, for example, from 192.168.0.0/24 to 10.10.0.0/24.
A reference service belongs to a single service or group of services, a so-called service, that is a set of service agreements provided by the layers in the network to its upper layers. Common service types include FTP (File Transfer Protocol), HTTP (HyperText Transfer Protocol), DNS (Domain Name System), and the like.
In the bandwidth policy, the configuration reference service may limit traffic, for example, HTTP traffic may be limited assuming the configured service is HTTP.
The reference user is a single user or a user group, namely a user needing to be authenticated to surf the internet.
In the bandwidth policy, the configuration reference user may allocate the size of the available bandwidth to the user, for example, assuming a user group, the available bandwidth of all users in this user group may be limited.
The reference application is a network application, i.e. an application that needs to perform network communication.
In the bandwidth policy, the configuration reference application may limit the speed of the application, for example, assuming that the mailbox client and the downloading tool are configured, the necessary bandwidth may be allocated to the mailbox client mostly, and the bandwidth available for the downloading tool is reduced.
In one case, the source domain, the destination domain and the reference domain are compared, and if the source domain and the destination domain belong to the reference domain, it is determined that the header information is successfully matched with the bandwidth policy.
At this time, the packet may be allocated to the bandwidth channel corresponding to the bandwidth policy (reference field) to limit the flow.
In another case, the source IP address, the destination IP address and the reference address are compared, and if the source IP address and the destination IP address belong to the reference address, it is determined that the header information and the bandwidth policy are successfully matched.
At this time, the packet may be allocated to the bandwidth channel corresponding to the bandwidth policy (reference address) to limit the flow.
In another case, the source service is compared with the reference service, and if the source service belongs to the reference service, it is determined that the header information is successfully matched with the bandwidth policy.
At this time, the packet may be allocated to the bandwidth channel corresponding to the bandwidth policy (reference service) to limit the flow.
In another case, the source user is compared with the reference user, and if the source user belongs to the reference user, it is determined that the message header information is successfully matched with the bandwidth policy.
At this time, the packet may be allocated to the bandwidth channel corresponding to the bandwidth policy (reference user) to limit the flow.
In another case, the source application is compared with the reference application, and if the source application belongs to the reference application, it is determined that the header information is successfully matched with the bandwidth policy.
At this time, the packet may be allocated to the bandwidth channel corresponding to the bandwidth policy (reference application) to limit the flow.
For a certain service requirement, the priority of the bandwidth policy may be configured as:
the priority of the bandwidth strategy to which the reference domain belongs is higher than that of the bandwidth strategy to which the reference address belongs;
the priority of the bandwidth strategy to which the reference address belongs is higher than that of the bandwidth strategy to which the reference protocol belongs;
the priority of the bandwidth strategy to which the reference protocol belongs is higher than that of the bandwidth strategy to which the reference user belongs;
the bandwidth policy to which the reference user belongs has a higher priority than the bandwidth policy to which the reference application belongs.
In this case, as shown in fig. 3, the flow of matching the header information with the bandwidth policy is as follows:
in step S21, it is determined whether the source domain and the destination domain belong to the reference domain; if so, go to step S26, otherwise, go to step S22.
In step S22, it is determined whether the source IP address and the destination IP address belong to the reference address; if so, go to step S26, otherwise, go to step S23.
In step S23, it is determined whether the source service belongs to the reference service; if so, go to step S26, otherwise, go to step S24.
Step S24, judging whether the source user belongs to the reference user; if so, go to step S26, otherwise, go to step S25.
Step S25, judging whether the source application belongs to the reference application; if so, go to step S26, otherwise, go to step S27.
And step S26, determining that the message header information is successfully matched with the bandwidth strategy.
Step S27, it is determined that the matching between the header information and the bandwidth policy fails.
Of course, the bandwidth policies and the matching manners thereof are only examples, and when implementing the embodiment of the present invention, other bandwidth policies and matching manners thereof may be set according to actual situations, which is not limited in the embodiment of the present invention. In addition, besides the bandwidth policy and the matching method thereof, those skilled in the art may also adopt other bandwidth policies and matching methods thereof according to actual needs, and the embodiment of the present invention is not limited to this.
And 104, marking the message type of the message positioned in the bandwidth channel.
After the message is distributed to the adaptive bandwidth channel, the message type is marked according to the flow condition in the bandwidth channel, so that the subsequent control such as guarantee, current limitation and the like is carried out on the network interface according to the message type.
In a specific implementation, on one hand, the configuration information set for the bandwidth channel is read, and the single maximum bandwidth, the channel guaranteed bandwidth, and the channel maximum bandwidth set for the bandwidth channel are obtained.
Where an individual maximum bandwidth may refer to the maximum bandwidth available to each source IP address or user.
For example, the individual maximum bandwidth of each source IP address is configured to be 1Mbps, and all devices matched to the policy use a maximum bandwidth of 1 Mbps.
The channel guaranteed bandwidth may refer to the minimum uplink and downlink bandwidth available in the bandwidth channel, and may be used to guarantee the critical service to pass through.
For example, if the intranet mail system needs 5Mbps of traffic in normal use, the guaranteed bandwidth of the configured mail is 5Mbps, and the configuration is referred by the policy of configuring the mailbox client, so that the message of the mail can use at least 5Mbps of guaranteed traffic, and the mail service is guaranteed not to be blocked because other services seize the bandwidth.
The maximum bandwidth of a channel may refer to the maximum uplink and downlink bandwidth available in the bandwidth channel, and may be used to limit the upper limit of the bandwidth used by some traffic.
For example, the maximum bandwidth is configured to be 5Mbps, and the configuration is referenced by a policy that configures the download tool so that the maximum speed of downloading using the download tool is 5 Mbps.
On the other hand, the total flow bandwidth occupied by all the messages in the bandwidth channel before the current message is distributed to the bandwidth channel can be calculated, and the single average bandwidth occupied by the message after the message is distributed to the bandwidth channel can be calculated.
Specifically, the configuration information set for the bandwidth channel is read, the maximum bandwidth of the channel set for the bandwidth channel is obtained, the number of source IP addresses or users in the bandwidth channel is queried, and the maximum bandwidth of the channel is divided by the number, so that the individual average bandwidth occupied by each source IP address or message corresponding to a user can be obtained.
At this time, three conditions are set:
the first condition is that the individual average bandwidth exceeds the average bandwidth;
the second condition is that the total bandwidth of the traffic exceeds the guaranteed bandwidth;
the third condition is that the total bandwidth of traffic exceeds the maximum bandwidth.
Comparing the current flow conditions (total flow bandwidth and single average bandwidth) with the standards (single maximum bandwidth, channel guaranteed bandwidth and channel maximum bandwidth) of the bandwidth channel, and judging whether the three conditions are met:
in one case, the message type of the message is marked as a guaranteed message if the message does not conform to the first condition and the second condition.
In another case, if the message does not meet the first condition and the third condition and meets the second condition, the message type of the message is marked as a flow limited message.
In addition, if the message meets the first condition, the message is discarded.
Or if the message does not accord with the first condition and accords with the second condition and the third condition, discarding the message.
In one embodiment, as shown in FIG. 4, the comparison flow is as follows:
in step S31, it is determined whether the individual average bandwidth exceeds the individual maximum bandwidth; if yes, go to step S34; if not, step S32 is executed.
In step S32, it is determined whether the total traffic bandwidth exceeds the guaranteed channel bandwidth; if yes, go to step S33; if not, step S35 is executed.
In step S33, whether the total traffic bandwidth exceeds the maximum bandwidth of the channel; if yes, go to step S34; if not, step S36 is executed.
And step S34, discarding the message.
Step S35, mark the message type of the message as a guaranteed message.
And step S36, marking the message type of the message as a speed limit message.
Of course, the above message types and the setting modes thereof are only examples, and when the embodiment of the present invention is implemented, other message types and setting modes thereof may be set according to actual situations, which is not limited in the embodiment of the present invention. In addition, besides the above message types and setting manners, those skilled in the art may also adopt other message types and setting manners according to actual needs, and the embodiment of the present invention is not limited thereto.
And 105, performing transmission control on the message according to the message type.
In this embodiment, the message with the flag is processed at the speed limit of the network interface, such as ensuring and limiting.
In a specific implementation, a configuration file set for a network interface is read, and a maximum bandwidth and a reserved bandwidth set for the network interface are obtained.
The maximum bandwidth refers to the upper limit of the bandwidth in the input/output direction of the network interface, the configurable bandwidth range is 8Kbps-10Gbp, all traffic of the maximum bandwidth can be used, and the maximum bandwidth allowed by the network interface can be limited.
The reserved bandwidth refers to a reserved bandwidth in an egress/ingress direction of a network interface, and the reserved bandwidth only allows some types of traffic (such as guaranteed packets) to pass through, so as to ensure that packets of a critical service are not discarded.
At this point, the current traffic situation can be compared with the standards of the network interface (maximum bandwidth and reserved bandwidth):
in one case, if the message is a speed-limit message and the maximum bandwidth has a first idle bandwidth except the reserved bandwidth, the message is sent while occupying the first idle bandwidth.
In another case, if the message is a speed limit message and the maximum bandwidth does not have the first idle bandwidth except the reserved bandwidth, the message is discarded.
In another case, if the message is a guaranteed message and the reserved bandwidth has a second idle bandwidth, the message is sent while occupying the second idle bandwidth.
In another case, if the message is a guaranteed message, the reserved bandwidth does not have the second idle bandwidth, and the maximum bandwidth has the first idle bandwidth except the reserved bandwidth, the message is sent while occupying the first idle bandwidth.
In another case, if the message is a guaranteed message, and the reserved bandwidth does not have the second idle bandwidth, and the maximum bandwidth does not have the first idle bandwidth except the reserved bandwidth, the message is discarded.
The first idle bandwidth and the second idle bandwidth both belong to idle bandwidths, that is, unoccupied bandwidths.
Aiming at the reserved bandwidth, if the messages discarded at the network interface contain the guarantee messages, the reserved bandwidth can be dynamically adjusted up, so that the guarantee messages can pass through preferentially, and excessive bandwidth cannot be occupied by the speed limit messages of a large number of noncritical services.
In one embodiment, the configuration file is read to obtain the maximum bandwidth set in advance for the bandwidth channel.
And taking a specified proportion for the maximum bandwidth to obtain an up-regulation value, and performing up-regulation according to the up-regulation value on the basis of the reserved bandwidth until the up-regulation value is up-regulated to the upper limit value.
For example, the pitch value may be calculated by the following formula:
32Kbps interface configuration (Kbps)/(10 1024Kbps)
If 10Mbps is configured, the reserved bandwidth of the network interface may be increased by 32Kbps, where the highest up-link line is 256 Kbps.
And if the discarded message does not contain the guarantee message, dynamically calling back the reserved bandwidth until the reserved bandwidth falls to the initial value.
In one embodiment, the first number of guaranteed messages for the last time period (e.g., the last second) of the bandwidth channel is recorded.
With the first number as a reference, a second number of guaranteed messages in a next time period (next second) is estimated.
For example, assuming that the number of packets in a short time period is balanced, it may be considered that the first number of guaranteed packets in the previous time period is equal to the second number of guaranteed packets in the next time period.
And calculating a down-regulation value according to the second quantity, and performing down-regulation according to the down-regulation value on the basis of the reserved bandwidth until the down-regulation value falls back to the original value.
In the embodiment of the present specification, a message is received, message header information is read from the message, the message is allocated to a bandwidth channel adapted to the message header information, a message type is marked for the message located in the bandwidth channel, transmission control is performed on the message according to the message type, and corresponding bandwidth management is performed based on the bandwidth channel and the message type, so that multiple configuration schemes can be implemented, bandwidth is more reasonably allocated, bandwidth exhaustion is avoided, a configuration flow is simplified, a network administrator is effectively helped to reasonably allocate bandwidth resources, and thus network operation quality is improved.
