Embodiment

[0018] Such as figure 1 As shown, a bandwidth saving control device based on a NAT address translator, including a bgp dedicated line access terminal 1, a bgp access gateway 2, a NAT address translator 3, a common bandwidth 4 and a bgp peer device 5, the described The bgp dedicated line access terminal 1 is connected to the NAT address translator 3 through the bgp access gateway 2, the bgp access gateway 2 is connected to the bgp peer device 5, and the NAT address translator 3 is connected to the common bandwidth 4 .

[0019] There are multiple bgp dedicated line access terminals 1, which are respectively connected to bgp access gateways 2. There are multiple common bandwidths 4, which are respectively connected to the NAT address translator 3. The bgp access gateway 2 is connected to a bgp peer device through a bgp link.

[0020] The bgp access gateway analyzes the source data packet, separates the web access external network traffic through policy routing, and inputs it t...

Abstract

The invention relates to a bandwidth saving control device based on an NAT address translator. The bandwidth saving control device comprises a bgp special line access end, a bgp access gateway, the NAT address translator, a common bandwidth and bgp peer equipment, wherein the bgp special line access end is connected with the NAT address translator through the bgp access gateway, the bgp access gateway is connected with the bgp peer equipment, and the NAT address translator is connected with the common bandwidth. Compared with the prior art, the bandwidth saving control device based on the NAT address translator has the advantages of effectively reducing cost, increasing communication quality, being small in scope of influence and the like.

Description

technical field [0001] The invention relates to a bandwidth saving control device, in particular to a bandwidth saving control device based on a NAT address translator. Background technique [0002] For second-tier operators, it is very expensive to purchase BGP bandwidth and IP address announcements from first-tier operators such as China Telecom or China Unicom, and many users do not need BGP bandwidth for ordinary Internet access. Active access to the external network traffic is separated from IP, and converted to ordinary broadband access to the Internet through a NAT conversion device, thereby achieving the purpose of saving expensive BGP bandwidth and saving a lot of BGP bandwidth expenses for enterprises. [0003] Although the existing CDN caching mechanism can also save traffic, it is not suitable for the downlink traffic model of active access due to the huge investment and high operating costs due to the deployment of cache nodes across the country, and this techno...
