Today, with the popularity of the Internet, no matter the business interaction between enterprises, or the communication and interaction between users and terminals, have put forward new requirements for the wide area network. In order to ensure the intelligence and automation of the network, it is necessary to extend the local area network to the wide area network, which increases the complexity and scalability of the wide area network.

Today, in a complex cloud environment with private cloud, public cloud, and SaaS, everyone needs to rely on the Internet to provide all aspects of services, which requires an intelligent WAN on the Internet to ensure that we can enjoy a variety of application experiences.

With the increasing number of applications hosted in the cloud and networked devices, the WAN has undergone an unprecedented transformation. Enterprises must rely on the Internet to connect users with critical business applications. Based on this, Cisco defines a new concept-Cloud Edge (Cloud Edge), the intersection of security layer, network, and cloud.

In the open Internet, the congestion and performance of the network are uncertain. At the same time, the application of the new cloud environment brings higher security risks, uneven application performance and increasing complexity. Virtually every WAN device must support software definitions and be protected.

A few days ago, during the Cisco 2018 Global partner Conference in Las Vegas, Cisco announced that it was integrating its security and software-defined wide area network (SD-WAN) technology to provide businesses with more options to adopt cloud technology confidently and faster.

The performance of the new Office Software-defined WAN software can be improved by up to 40% in three dimensions: full-stack security, simplified cloud security, and Cisco 365. With the IOS-XE version, firewall, IPS, and URL filtering capabilities are integrated into the software-defined WAN platform, providing an end-to-end full-stack security.

Cao Tuqiang believes that the security we are talking about is no longer what it used to be, and it no longer has particularity, but has become a daily necessity. With Cisco Umbrella (currently available in Hong Kong and Taiwan), you can help users accelerate deployment and increase visibility in the WAN.

The OnRamp capabilities of Office Software-defined wide area Network (Viptela) help Office 365 users find the fastest Office 365 server anytime and anywhere, providing the best user experience by determining the fastest path for users, thereby improving Office 365 performance by up to 40%.

Cisco has always been committed to effectively addressing emerging cloud edge challenges by improving its SD-WAN portfolio. "taking into account security and application experience without compromise" is the concept of Cisco Software-defined WAN, which provides users with the best application experience while security is guaranteed, both aspects need to be balanced rather than compromised. In addition to providing a superior security and application experience, the Cisco Software-defined WAN is open and programmable.

▲ Software-defined WAN portfolio

To further expand the product portfolio of software-defined WANs, ISR is about to launch two ISR products in China: Cisco 1111 Xmur8P and ISR 4461. The ISR 1000 series offers a wide range of services, integrated Wi-Fi and LTE, with software-defined WAN and integrated security capabilities. It is worth noting that the ISR 4461 is the most scalable and high-performance model in the series.

▲ Gartner Magic Quadrant Leader for WAN, access and Firewall

As the industry's leading network provider, Cisco is rated by Gartner as the leader in the magic quadrant of WAN edge, network firewall, and wired and wireless Lans. It is the only vendor in the industry that leads the three magic quadrants at the same time, fully demonstrating Cisco's strong momentum in the WAN, security, and LAN.

Talking about Cisco's advantages in SD-WAN, Cao Tuqiang revealed that Cisco first proposed an intention-based network in the local area network and turned it into a fully intelligent network of intelligence, automation, continuous self-evolution and self-learning, thus providing everyone with the best user experience.

Second, Cisco's security is the best security in the world, the security requirements in the wide area network are more stringent than the local area network, and the security field is Cisco's advantage. Cisco is currently integrating all the intelligence of security and the network, which is why customers choose the Cisco WAN solution.

In summary, the Cisco Software-defined WAN can leverage the best threat intelligence, deploy security features quickly and appropriately, provide the best user experience, and have no impact on connectivity to any cloud. Because of its unified architecture, it combines best-in-class software-defined WAN and security capabilities into a single user interface and a single usage model, giving users a more secure application experience.
