Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flowchart of a multilink-based data forwarding method according to an embodiment of the present invention.
The multilink-based data forwarding method provided by the embodiment of the invention comprises the following steps:
and S11, determining the load state of a plurality of links which are connected between the equipment and another equipment.
Wherein the load state includes an idle state and an overload state.
Specifically, the step S11 specifically includes:
s111, acquiring the bandwidth occupancy rates of the multiple links which are connected between the equipment and the other equipment.
Illustratively, for wireless Backhaul, bandwidth occupancy is equal to channel occupancy, and for wireline Backhaul, bandwidth occupancy is equal to the ratio of the sum of the throughput of all traffic on the link to the total bandwidth.
Specifically, when a certain link is a wired link, the present device specifically obtains the bandwidth occupancy rate of the wired link by the following method:
s1111, acquiring the throughput of all the flow on the wired link;
s1112, calculating the sum of the throughputs of all the flows;
s1113, obtaining the total bandwidth of the wired link;
s1114, calculating the ratio of the sum of the throughputs to the total bandwidth to obtain the bandwidth occupancy rate of the wired link.
And S112, comparing the size relationship between the bandwidth occupancy rates of the plurality of links and a preset bandwidth occupancy rate threshold value.
It should be noted that, in a specific implementation, the preset bandwidth occupancy threshold may be set according to an actual need, and is not limited herein.
S113, judging that the load states of all the links with the bandwidth occupancy rates smaller than or equal to the preset bandwidth occupancy rate threshold value are idle states according to the size relation.
And for each Backhaul, if the bandwidth occupancy rate of the Backhaul does not exceed the preset bandwidth occupancy rate threshold, the Backhaul can be judged to be in an idle state.
And S114, judging the load state of all the links with the bandwidth occupancy rates larger than the preset bandwidth occupancy rate threshold value to be an overload state according to the size relation.
And for each Backhaul, if the bandwidth occupancy rate exceeds a preset bandwidth occupancy rate threshold, judging that the Backhaul is in an overload state.
In this embodiment, the bandwidth occupancy of the multiple links that have established the connection between the first device and the second device is obtained and compared with the preset bandwidth occupancy threshold, so that the load states of the multiple links can be accurately determined.
And S12, acquiring the pre-configured priorities of the plurality of links.
It should be noted that the priorities of the multiple links may be set by the Mesh device itself.
S13, determining the optimal link in the plurality of links based on the load states and the priorities of the plurality of links.
Specifically, for example, a link with the best communication quality may be selected from the multiple links as the optimal link based on the load states and the priorities of the multiple links.
Preferably, the step S13 specifically includes:
s131, determining a plurality of candidate links in an idle state in the plurality of links based on the load states of the plurality of links.
S132, based on the priorities of the candidate links, selecting a link with the highest priority from the candidate links as an optimal link.
In this embodiment, an un-overloaded link with the highest priority is searched as an optimal link, which can ensure that the optimal link can subsequently accommodate enough adjustment traffic and ensure the forwarding efficiency of the traffic.
S14, based on the load state and the priority of the links, selecting a plurality of links with the priority not lower than the optimal link and in an overload state from the links as a first link set, and selecting a plurality of links with the priority lower than the optimal link as a second link set.
After the optimal link is determined, based on the load states and priorities of the multiple links, searching for all links with priorities lower than the optimal link from the multiple links as a first link set, and all overloaded links with priorities not lower than a target link as a second link set, so as to adjust the flow subsequently.
S15, adjusting the flow of the link in the first link set and the second link set to be forwarded by the optimal link.
And adjusting the traffic of the links in the first link set and the second link set to be forwarded by the optimal link, so that the traffic of the overloaded link is adjusted to the idle link, and the traffic is adjusted to the idle link with higher priority.
For a certain traffic, it may specifically be that a packet sending network interface of a forwarding entry corresponding to the traffic in a forwarding table is modified into an optimal link, so as to adjust the traffic to be forwarded by the optimal link.
It should be noted that the embodiment of the present invention may be applied to various data transmission occasions based on multilink, and is particularly applicable to data transmission between routing devices of Mesh networking.
In the multilink-based data forwarding method provided in the embodiment of the present invention, an optimal link of a plurality of links is determined based on load states and priorities of the plurality of links that have established a connection between the device and another device, and a plurality of links having priorities not lower than that of the optimal link and being in an overload state are selected from the plurality of links as a first link set and a plurality of links having priorities lower than that of the optimal link as a second link set, and then traffic on links in the first link set and the second link set is adjusted to be forwarded by the optimal link, thereby implementing multilink-based data forwarding. Based on the above analysis, it can be seen that the embodiment of the present invention can adjust the traffic from the overloaded link to the idle link for forwarding, so as to achieve the effect of balancing the link load, and can preferentially allocate the traffic to the high-priority link for forwarding according to the priority of the link, which is beneficial to improving the network performance and improving the network application experience.
In specific implementation, the multilink-based data forwarding method provided by the embodiment of the present invention may be triggered by a timer and a topology change event.
As an alternative embodiment, referring to fig. 2, the method further includes:
s21, determining the link types of the plurality of links; wherein the link types include a wired link, a 5G link, and a 2G link.
S22, configuring the priorities of the links according to the link types to which the links belong based on the corresponding relation between the preset link types and the link priorities;
the correspondence between the link type and the link priority is specifically that the wired link corresponds to a first priority, the 5G link corresponds to a second priority, and the 2G link corresponds to a third priority, where the first priority is greater than the second priority, and the second priority is greater than the third priority.
In this embodiment, the priorities of the plurality of links are configured according to the correspondence between the preset link types and the link priorities and the determined link types to which the plurality of links belong, so that the transmission quality of the link can be better reflected by the priorities of the links, and the effect of flow adjustment is ensured.
As an alternative embodiment, referring to fig. 2, the step S15 specifically includes:
s151, according to the sequence of the priorities of the links from low to high, adjusting the flow on each link in the first link set to be forwarded by the optimal link according to a preset flow adjustment strategy;
and S152, according to the sequence of the priorities of the links from high to low, sequentially adjusting the traffic on each link in the second link set to be forwarded by the optimal link according to the traffic adjustment strategy.
It should be noted that the execution order of step S151 and step S152 is not limited herein, for example, step S151 may be executed before step S152, or after step S152, or may be executed in synchronization with step S152, which does not affect the beneficial effects obtainable by the present invention.
In this embodiment, since the priorities of the links in the second link set are all lower than the optimal link, the traffic on the links in the second link set should be adjusted to the link with better quality, and since the traffic is adjusted to the link with better quality, the link with the best quality in the second link set should have the right to adjust the priority, and therefore, for the links with priorities lower than the optimal link, the traffic is adjusted to the optimal link according to the preset traffic adjustment policy in sequence from high to low. For a plurality of links with higher priority than the target link, because the flow is adjusted to the link with poorer quality, the link with the best quality in the first link set is adjusted last, and therefore the flow is adjusted to the optimal link according to the preset flow adjustment strategy in sequence from low to high in priority.
Further, the flow rate adjustment policy specifically includes:
s31, calculating the idle bandwidth of the optimal link;
s32, determining the throughput of each flow on the current adjusted link;
s33, judging whether a plurality of flows to be adjusted with the throughput not larger than the idle bandwidth of the optimal link exist on the current adjusted link or not according to the idle bandwidth of the optimal link and the throughput of each flow on the current adjusted link, judging whether the number of the adjusted flows is smaller than a preset configuration number or not, if so, executing the step S34, and if not, ending the flow adjustment process of the current adjusted link; wherein the initial value of the number of the regulated flows is 0, and the configuration number is greater than or equal to 1;
s34, determining which set of the first link set and the second link set the currently adjusted link belongs to, if the currently adjusted link belongs to the first link set, executing step S35, and if the currently adjusted link belongs to the second link set, executing step S36;
s35, when the currently adjusted link is judged to belong to the first link set, judging whether the traffic of which the type is TCP/UDP non-fragmented messages exists in the plurality of traffic to be adjusted, if so, selecting the traffic with the maximum throughput from the plurality of traffic of which the type is TCP/UDP non-fragmented messages as the current adjustment traffic, and executing a step S37, if not, selecting the traffic with the maximum throughput from the plurality of traffic of which the type is non-TCP/UDP messages or TCP/UDP fragmented messages as the current adjustment traffic, and executing a step S37;
s36, when the currently adjusted link is judged to belong to the second link set, judging whether the traffic of which the type is TCP/UDP non-fragmented messages exists in the plurality of traffic to be adjusted, if so, selecting the traffic with the minimum throughput from the plurality of traffic of which the type is TCP/UDP non-fragmented messages as the current adjustment traffic, and executing a step S37, if not, selecting the traffic with the minimum throughput from the plurality of traffic of which the type is non-TCP/UDP messages or TCP/UDP fragmented messages as the current adjustment traffic, and executing a step S37;
s37, adjusting the current adjusted flow to be forwarded by the optimal link, increasing the number of the adjusted flow by 1, and returning to the step S31.
For example, in a specific implementation, when each flow corresponds to a packet, the device may count and record the byte number of the packet, and then step S32 may specifically be to determine the throughput of each flow on the currently adjusted link by directly reading the byte number of the packet of each flow recorded in the device. In addition, the traffic on the currently adjusted link may also be traversed, so as to obtain the throughput of each traffic on the currently adjusted link, which is not limited herein.
It should be noted that the configuration number is used to indicate the number of the traffic forwarded to the optimal link in each traffic adjustment process.
Illustratively, the method for calculating the idle bandwidth of the optimal link specifically includes:
acquiring the negotiation rate and the bandwidth occupancy rate of the optimal link;
calculating the idle bandwidth of the optimal link according to the negotiation rate and the bandwidth occupancy rate of the optimal link and a preset conversion factor; and the idle bandwidth of the optimal link is equal to the product of the negotiation rate, the bandwidth occupancy rate and the conversion factor.
Wherein the conversion factor is a configurable constant.
In this embodiment, traversing all traffic whose throughput is not higher than the idle bandwidth of the optimal link from the currently adjusted link, adjusting traffic classified by the quintuple when adjusting the traffic, and after the adjustment is completed, if the optimal link has the idle bandwidth, adjusting the traffic classified by the MAC address, and preferentially adjusting the traffic with smaller throughput for the link with the priority lower than the optimal link, and preferentially adjusting the traffic with larger throughput for the link with the priority not lower than the optimal link, and after the adjustment, re-optimizing the idle bandwidth of the link, and deciding the traffic to be adjusted again until the optimal link cannot accommodate any traffic, thereby improving the efficiency of load balancing and avoiding overload of the optimal link.
As one optional embodiment, the present device forwards traffic to the other device specifically by:
s371, determining the type of the traffic to be forwarded that needs to be forwarded to the other device; the types comprise TCP/UDP non-fragment messages, non-TCP/UDP protocol messages and TCP/UDP fragment messages;
s372, if the traffic to be forwarded is a TCP/UDP non-fragmented message, taking the message quintuple of the traffic to be forwarded as matching item information of the traffic to be forwarded;
s373, if the traffic to be forwarded is a non-TCP/UDP protocol message or a TCP/UDP fragmentation message, taking the MAC address of the traffic to be forwarded as matching item information of the traffic to be forwarded;
s374, searching forwarding items corresponding to the traffic to be forwarded in a pre-configured forwarding table according to the matching item information of the traffic to be forwarded; the forwarding table is used for recording forwarding entries of traffic in the plurality of links, and the forwarding entries at least comprise matching item information and a packet sending network interface used for indicating the link for transmitting the traffic;
s375, when the forwarding entry corresponding to the traffic to be forwarded is found, forwarding the traffic to be forwarded based on the forwarding entry corresponding to the traffic to be forwarded;
s376, when the forwarding entry corresponding to the traffic to be forwarded cannot be found, establishing a forwarding entry corresponding to the traffic to be forwarded in the forwarding table according to the matching item information and the parameter information of the traffic to be forwarded, and forwarding the traffic to be forwarded based on the forwarding entry corresponding to the traffic to be forwarded; wherein the parameter information at least comprises a packet network interface.
In this embodiment, a forwarding table entry configuration interface is provided by a forwarding table based on a five-tuple and based on an MAC address, and when a traffic adjustment decision is changed, a packet network interface that changes traffic is modified by the configuration interface, so that when traffic needs to be forwarded, the current traffic to be forwarded is sent to the packet network interface in the corresponding forwarding entry, so as to forward the current traffic to be forwarded to another device from an allocated link, thereby managing and controlling the forwarding directions of various types of traffic, replacing the original forwarding control of a bridge, and enabling the forwarding direction to be controlled by an application layer.
In a specific embodiment, the forwarding entry further includes a packet receiving network interface and traffic statistics for indicating the throughput of the traffic.
Then, the step S375 may specifically be: when the forwarding entry corresponding to the traffic to be forwarded is found, updating the packet receiving network interface and the traffic statistical information in the forwarding entry corresponding to the traffic to be forwarded according to the packet receiving network interface and the throughput of the traffic to be forwarded, and sending the traffic to be forwarded to the packet sending network interface recorded in the forwarding entry corresponding to the traffic to be forwarded.
Then, the parameter information in step S376 may specifically further include a packet receiving network interface and throughput, and step S376 may specifically be: and when the forwarding entry corresponding to the flow to be forwarded cannot be found, establishing the forwarding entry corresponding to the flow to be forwarded in the forwarding table according to the matching item information and the parameter information of the flow to be forwarded, and sending the flow to be forwarded to a packet sending network interface recorded in the forwarding entry corresponding to the flow to be received.
It should be noted that, when finding the forwarding entry corresponding to the traffic to be forwarded, comparing whether the packet receiving network interface of the traffic to be forwarded is consistent with the record on the forwarding entry, if not, indicating that the traffic adjustment or site roaming and other situations occur, updating the packet receiving network interface recorded by the entry at this time, thereby ensuring the accuracy of data forwarding, and recording the throughput of the traffic to be forwarded in the traffic statistic information for subsequent use in traffic adjustment.
Specifically, the throughput of each flow to be forwarded is counted according to the number of bytes of the packet when receiving the packet.
For example, for a traffic containing TCP/UDP fragmentation messages, all messages in the traffic are prohibited from matching forwarding table entries in a five-tuple manner within a configurable time t.
Correspondingly, the embodiment of the invention also provides a multilink-based data forwarding device, which can implement all the processes of the multilink-based data forwarding method.
