Abstract
The utility model relates to a controlling means is practiced thrift to bandwidth based on NAT address translator, including bgp access via telephone line end, bgp access gateway, NAT address translator, ordinary bandwidth and bgp peer -to -peer equipment, bgp access via telephone line end be connected with NAT address translator through bgp access gateway, bgp access gateway be connected with bgp peer -to -peer equipment, NAT address translator be connected with ordinary bandwidth. Compared with the prior art, the utility model has the advantages of the cost is reduced, improved communication quality, influence scope is little.
Description
Technical field
The utility model relates to a kind of bandwidth conservation control device, especially relates to a kind of bandwidth conservation control device based on NAT address translator.
Background technology
For second-level runner, from the one-level operator such as telecommunications or UNICOM buying BGP bandwidth sum IP address bulletin, price is very expensive, and the common online demand of a lot of user does not need BGP bandwidth, therefore user side initiatively accessed the flow of outer net by this device and IP separates, convert common wide access the Internet to by NAT conversion equipment, thus reach the object of saving expensive BGP bandwidth, for enterprise has saved very large BGP bandwidth cost expense.
Although existing cdn caching mechanism also can save flow, owing to will dispose cache node in the whole nation, drop into huge, operation cost is high, be not suitable for the downlink traffic model approach of initiatively access, and this technology can save enterprise's downlink bandwidth flow especially.
Utility model content
The purpose of this utility model be exactly provide a kind of reduce cost to overcome defect that above-mentioned prior art exists, improve communication quality, the bandwidth conservation control device based on NAT address translator that coverage is little.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of bandwidth conservation control device based on NAT address translator, it is characterized in that, comprise bgp access via telephone line end, bgp IAD, NAT address translator, common bandwidth sum bgp peer device, described bgp access via telephone line end is connected with NAT address translator by bgp IAD, described bgp IAD is connected with bgp peer device, and described NAT address translator is connected with common bandwidth.
Described bgp access via telephone line end is provided with multiple, is connected respectively with bgp IAD.
Described common bandwidth is provided with multiple, is connected respectively with NAT address translator.
Described bgp IAD is connected with bgp peer device by bgp link.
Compared with prior art, the utility model has the following advantages:
1, reducing cost, by arranging NAT address translator, thus greatly saving BGP bandwidth resources;
2, coverage is little, and BGP bandwidth resources can be converted on common wide by NAT address converting device, and does not affect the proper network access of user.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
As shown in Figure 1, a kind of bandwidth conservation control device based on NAT address translator, comprise bgp access via telephone line end 1, bgp IAD 2, NAT address translator 3, common bandwidth 4 and bgp peer device 5, described bgp access via telephone line end 1 is connected with NAT address translator 3 by bgp IAD 2, described bgp IAD 2 is connected with bgp peer device 5, and described NAT address translator 3 is connected with common bandwidth 4.
Described bgp access via telephone line end 1 is provided with multiple, is connected respectively with bgp IAD 2.Described common bandwidth 4 is provided with multiple, is connected respectively with NAT address translator 3.Described bgp IAD 2 is connected with bgp peer device by bgp link.
Described bgp IAD is analyzed source data packet, web is accessed outer net flow and is separated by policybased routing, is input to NAT address translator.Described NAT address translator is that ip access in broadband is interconnected according to sourceip address transition.
At bgp IAD place, user is separated by the service port of extranet access and IP, and the IP that access is come in is identified and got rid of, output to original bgp peer-to-peer exit by policybased routing, access the Internet.
Claims (4)
1. the bandwidth conservation control device based on NAT address translator, it is characterized in that, comprise bgp access via telephone line end, bgp IAD, NAT address translator, common bandwidth sum bgp peer device, described bgp access via telephone line end is connected with NAT address translator by bgp IAD, described bgp IAD is connected with bgp peer device, and described NAT address translator is connected with common bandwidth.
2. a kind of bandwidth conservation control device based on NAT address translator according to claim 1, is characterized in that, described bgp access via telephone line end is provided with multiple, is connected respectively with bgp IAD.
