Abstract
The utility model relates to multi-channel load balancing equipment which comprises a processor, a plurality of WAN interfaces, an LAN interface, wherein the processor is connected with the WAN interfaces and the LAN interface. Compared with the prior art, the equipment has the advantages of high balancing efficiency, good reliability and the like.
Description
Technical field
The utility model relates to a kind of load-balancing device, especially relates to a kind of multichannel load-balancing device.
Background technology
Existing load-balancing device all is the load balancing to data flow, and this situation can't obtain the feedback of link-quality, when link occurs congested or breaks off, a large amount of packet losses may occur and need retransmitting, and so balanced efficient is hanged down poor reliability.
1. present existing Network Load Balance strategy mainly contains conversational, 2. weight poll formula and 3. three kinds of flow-types, wherein:
1. conversational is to be digit with the session number; All sessions are evenly distributed to the passage that all are launched in average ratio; The shortcoming of this mode is can not occur unbalanced simultaneously at the line bandwidth that inserts; It is congested to cause a passage to occur, and other passages also have surplus, and this is not truly load balancing.
2. weight poll formula also is by session, but the ratio of session can be regulated manually.Network communication is continuous earthquake, and dead this weight of artificial setting can not adapt to the variation of network.
3. the flow mode is to distribute load automatically by flow; Automatically seek the minimum channel communications of flow; Though this mode has certain intelligence; But the flow of (particularly wireless communication field) this passage will reduce when some channel transfer are second-rate, and load balancing will will cause the Packet Error Ratio rising and then cause re-transmission to have a strong impact on efficiency of transmission the flow equalization of other passages to this passage so so.
The utility model content
The purpose of the utility model is exactly the multichannel load-balancing device that a kind of balanced efficient height, good reliability are provided for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme:
A kind of multichannel load-balancing device is characterized in that, comprises processor, a plurality of WAN mouth, a LAN mouth, and described processor is connected with a plurality of WAN mouths, a LAN mouth respectively.
Described processor is the processor that route balance policing algorithm software is housed.
Described WAN mouth is provided with 4, and each WAN mouth one end is connected with respective channel through Ethernet interface, and the other end is connected with processor communication through the Ethernet agreement.
Described LAN mouth one end is connected with respective channel through Ethernet interface, and the other end is connected with processor communication through the Ethernet agreement.
Compared with prior art, the utlity model has the data balancing of supporting multiple standard, with the priority binding of data are equilibriums to each packet, can the dynamic monitoring channel quality, balanced efficient is high, good reliability.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the balance policy algorithm software flow chart in the processor of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of multichannel load-balancing device comprises processor, a plurality of WAN mouth, a LAN mouth, and described processor is connected with a plurality of WAN mouths, a LAN mouth respectively.
Wherein each WAN mouth and LAN mouth all are the respectively corresponding passages of Ethernet interface, and processor is equipped with route balance policing algorithm software.Pass through the ethernet protocol communication between WAN mouth, LAN mouth and the processor.The function of every part is:
The WAN/LAN mouth: the data of load-balancing device are imported and exported.
Processor: the channel transfer quality (error rate and bandwidth usage) through judging each WAN mouth thus dynamically change this passway by weight; When needs transmission certificate bag; According to the route weight of priority of data packets and each passage packet is carried out route and realize load balancing, the balanced data bag is exported from different WAN mouths according to balance policy.
As shown in Figure 2, this figure is the main flow chart of the route balance policing algorithm software in the processor, and idiographic flow is explained as follows:
At first in the transmission quality of 1. locating to detect each passage (error rate and bandwidth usage).
2. locating to come the route weight thresholding of each passage is dynamically changed then, simultaneously the priority of judgment data bag according to error rate thresholding and bandwidth usage thresholding;
If the error rate or bandwidth usage are above respective threshold then in the route weight of 3. locating to reduce this passage; If the error rate and bandwidth usage are all in allowed band then increase the routing inquiry weight of this passage; Simultaneously according to priority of data packets be the packet specified circuit by; The good passage of allocation of packets transmission quality that priority is high, the weaker passage of data allocations transmission quality that priority is low.
Packet is carried out concrete route and delivers to corresponding passage, 4. accomplished load-balancing function this moment.
Then 1. 2. 3. 4. carry out the route balance of next packet more set by step, by that analogy.
The utility model can be supported the passage of multiple standard; Like GSM, GSM-R, WCDMATD-SCDMA, wifi and LTE etc.; Based on the balance policy of each priority of data packets, at first judge the transmission quality (comprising the error rate, bandwidth usage) of each priority of data packets and each passage, the data that priority is high are walked the high passage of transmission quality; The data that priority is low are walked the weaker passage of transmission quality, thereby reach balanced high efficiency and high reliability.
Claims (3)
1. a multichannel load-balancing device is characterized in that, comprises processor, a plurality of WAN mouth, a LAN mouth, and described processor is connected with a plurality of WAN mouths, a LAN mouth respectively.
2. a kind of multichannel load-balancing device according to claim 1 is characterized in that described WAN mouth is provided with 4, and each WAN mouth one end is connected with respective channel through Ethernet interface, and the other end is connected with processor communication through the Ethernet agreement.
3. a kind of multichannel load-balancing device according to claim 1 is characterized in that, described LAN mouth one end is connected with respective channel through Ethernet interface, and the other end is connected with processor communication through the Ethernet agreement.
