WNT高速直连公有云、私有云，解决丢包，降低延迟

在双11之前，针对可预期的业务增长，企业运维部门会增加公有云服务器的配置；双11之后，业务量下降，则减少公有云服务器的配置。公有云的使用很方便，极具弹性，但是出于安全和竞争的考虑，几乎所有的企业对于核心业务、数据都使用私有云来存储。这就带来了公有云和私有云的连通、传输需求。

Before the double 11, the operation and maintenance department of the enterprise will increase the configuration of the public cloud server for the expected business growth; after the double 11, the business volume will decrease, the configuration of the public cloud server will be reduced. The use of public cloud is very convenient and flexible, but for the sake of security and competition, almost all enterprises use private cloud for core business and data storage. This brings the connection and transmission requirements of public cloud and private cloud.

目前，最常用的传输解决方案是公网：公有云——公网——私有云。在这个过程中，传输内容会受到两个问题的影响。其一，传输质量，公网传输必然遇到网络拥堵、丢包、延时等问题，破坏客户体验；其二，传输费用，公网传输的成本相对较高。

At present, the most commonly used transmission solution is the public network: public cloud - public network - private cloud. In this process, the transmission content will be affected by two problems. First, transmission quality, public network transmission will inevitably encounter network congestion, packet loss, delay and other problems, which will damage the customer experience; second, transmission costs, the cost of public network transmission is relatively high.

为了解决公有云和私有云之间的传输需求，主机参考正式推出WNT（Wormhole network transmission）“虫洞传输”。该服务是主机参考针对混合云企业定制的一款全新传输服务，通过主机参考的核心资源和技术，打通了一条数据中心和公有云的直连传输通道，帮助客户实现内网级的安全、高速、稳定传输。

In order to solve the transmission requirements between the public cloud and the private cloud, the host reference officially launched Wnt (worm network transmission) "wormhole transmission". This service is a new transmission service customized by host reference for hybrid cloud enterprises. Through the core resources and technologies of host reference, a direct transmission channel between data center and public cloud is opened to help customers realize safe, high-speed and stable transmission at the intranet level.

对于客户而言，这款产品可以直接解决公私云的传输痛点。内网级的传输，速度和质量上都有保证，以国内某最大公有云为例，本地电信到云端的传输大约是9—10ms；但通过WNT，从私有云到公有云，只需要3—4ms。与此同时，传输价格则只需要公网传输的30—40%。就像是两个相隔几百光年的宇宙空间，用一个宇宙虫洞，进行瞬间连接。这是一款既能提高效率又能降低成本的产品。

For customers, this product can directly solve the transmission pain of the public and private cloud. The transmission speed and quality at the intranet level are guaranteed. For exle, the transmission from local telecom to the cloud is about 9-10ms. However, through Wnt, the transmission from private cloud to public cloud only takes 3-4ms. At the same time, the transmission price only needs 30-40% of the public network transmission. It's like two cosmic spaces separated by hundreds of light-years, using a cosmic wormhole for instant connection. This is a product that can improve efficiency and reduce cost.

WNT高速通道优势特点：

Advantages of Wnt high-speed channel:

模式：数据中心与公有云直连，无需第三方转换；

Mode: the data center is directly connected to the public cloud without the need for third-party transformation;

安全：客户专线接入，不同于公网环境。MIP-SEC加密，确保安全；

Security: customer dedicated line access, different from public network environment. Mip-sec encryption to ensure security;

成本：零公网流量，更快响应，大幅度提升效率；

Cost: Zero public network traffic, faster response, greatly improving efficiency;

性能：24小时高速传输，无早晚高峰时延、丢包；

Performance: 24-hour high-speed transmission, no morning and evening peak delay, packet loss;

稳定：专线独享，全网冗余保护，单路毫秒切换；

Stable: exclusive dedicated line, redundant protection of the whole network, single channel millisecond switching;

功能：基于SDN架构，可登陆后台自助开通服务。

Function: Based on SDN architecture, you can log in the background self-service service.

以上对比了公网以及公网的技术手段，至少在六个方面，我们这款产品的优势都是很明显的。安全，WNT是专线接入，不同于公网环境。WNT采用MPLS结合SDN架构，加上IP-SEC加密技术，有效保障数据安全，避免劫持。成本上，降低了60%左右。

The above comparison of the public network and the technical means of the public network, at least in six aspects, the advantages of our product are very obvious. Security, Wnt is a special line access, different from the public network environment. Wnt adopts MPLS combined with SDN architecture and IP-Sec encryption technology to effectively guarantee data security and avoid hijacking. In terms of cost, about 60% has been reduced.

传输性能上，则是全天24小时高速转发网络，无早晚高蜂时延和丢包问题，低延迟，响应快。稳定性上，WNT采用专线独享，全网冗余保护，单路中断毫秒级切换，全天24小时不间断传输业务。此外，WNT基于SDN技术架构，用户可以登陆后台自助开通服务，使用情况一目了然。具体详询主机参考客服zhujicankao.com。

In terms of transmission performance, it is a 24-hour high-speed forwarding network, without high bee delay and packet loss in the morning and evening, with low delay and fast response. In terms of stability, Wnt adopts dedicated line exclusive, whole network redundancy protection, single channel interrupt millisecond level switching, and 24-hour uninterrupted transmission service. In addition, Wnt is based on SDN technology architecture, users can log in to the background self-service opening service, and the usage is clear at a glance.
