SD-WAN based on Internet-centric networking technologies

On July 25, 2018, Cisco introduced SD-WAN to Russian customers and partners based on Internet-oriented network technologies.

SD-WAN technology is designed to create flexible, scalable, distributed enterprise networks. Its feature is the separation of levels transport and control, which allows you to centrally manage the use of transport networks by remote branches.

author '= Andrey Kuzmich, Cisco Technology Director for Russia and CIS ' The Cisco SD-WAN solution improves the reliability of the distributed network, because it depends on this factor the continuity of business processes - whether orders are accepted, whether customers are served, whether operations are performed. Up to 80% of all operations in geographically distributed companies are performed in branches, as a result of which uninterrupted operation of applications in them is the most important IT task. This solution is based on Cisco's development in the field of IBN (Intent-based networking), which is the result of our work to create an intuitive system that can anticipate actions, neutralize security threats in the bud, and continuously improve and learn.

The implementation of Cisco SD-WAN will allow customers to significantly speed up the process of connecting additional branches and reduce associated costs. In fact, you can send the endpoint to the remote office by, and to mail configure it remotely by pressing a button in the central office. Cisco SD-WAN also optimizes carrier link costs without sacrificing customer service. This is achieved through a mix of transport infrastructure from providers - MPLS access to, Internet a 3G/4G mobile data network.

At the same time, the set of Quality experience functionality allows you to monitor the preservation of the level of operation of each specific application in real time, taking into account the current state of the channel.

Another key difference between Cisco SD-WAN is the level of protection against cyber threats. The reduction of information security risks in a distributed network is provided by a built-in set of measures - segmentation, encryption, support for logical topologies, service points, as well as external information security tools - both installed in the perimeter (ASA, NGFW) and cloud (Cisco Umbrella). As a result, network threat detection times are reduced hundreds of times, minimizing the potential loss to companies from data loss and information recovery costs.

The Cisco SD-WAN solution allows flexibility in the choice of terminal equipment, which can be both classic Cisco routers and original vEdge devices, as well as their virtualized versions.

Cisco SD-WAN management applications include a centralized orchestration and management system that can reside in both the Cisco cloud and the company's data center.

Citrix SD-WAN для Azure Virtual WAN

On July 19, 2018, Citrix and Microsoft announced a joint Citrix SD-WAN partner solution under the Azure cloud platform for the Azure Virtual WAN service . The joint solution is designed to improve the comfort and productivity of users, automate the tasks of deploying networks of branches of customer companies. Read more here.

2016: Service Offer Start

On October 27, 2016, Citrix announced the expansion of the functionality of the NetScaler SD-WAN platform to provide application delivery combined with intelligent routing technology.

Through NetScaler SD-WAN, Citrix offers customers a simple, end-to-end solution that helps scale-out SD-WAN, reduces the excessive complexity of company networks, and provides branch offices with easy, secure access to applications from the cloud.

NetScaler SD-WAN is a software-defined WAN technology focused on the use of one low-cost physical system with integrated control tools. Ready-to-use technology integrates application-specific WAN connection virtualization, dynamic routing, separate routing domains, optimization, end-to-end monitoring, Citrix HDX protocol support, and secure Internet switching. To simplify deployment and reduce its cost, Citrix is a system of secure cloud services Zero Touch Deployment. Zero Touch Deployment services eliminate the need for field technicians by automating the installation process and offer a special tool that prevents unauthorized devices from accessing the network.

NetScaler SD-WAN Overview Demo - virtual WAN solution, (2015)

NetScaler SD-WAN 9.1 functionality addresses the challenges companies face when upgrading their enterprise networks with SD-WAN:

• NetScaler SD-WAN offers an alternative to legacy branch office routers and allows companies to take a hybrid approach on the ground - companies can use existing routers where appropriate and migrate to the NetScaler SD-WAN platform without disruption.
• companies are able to create multiple virtual networks that are separated from each other. For example, Wi-Fi guest networks, point-of-sale data networks, and medical record data networks. The network can also be divided into company activities. This approach allows you to strengthen application protection in general and apply separate policies to each virtual network.
• Companies can begin implementing the SD-WAN platform by purchasing the available NetScaler SD-WAN 410 for individual branch offices. This model is designed for companies with many remote offices and can increase throughput up to 7 times without the need for new hardware.
• Zero Touch Deployment cloud-based and secure services enable IT to automate the installation process and eliminate the need for field setup. ZTD provides tiered protection and ensures that only systems owned by the company and located in a specific office are deployed.
• secure Internet switching in branches using a simplified connection to cloud security services, for example, Zscaler. Internet traffic originating from a branch office can be routed over a secure channel to a cloud security platform that offers Secure Web Gateway (SWG), cloud security gateway, sandbox creation mode, and other remote office security features. Similarly, NetScaler SD-WAN supports secure connectivity to major cloud service providers, including Amazon Web Services and Microsoft Azure.

Today, there are solutions on the market that are simply "sets of technologies" that require many systems, complex integration and suitable control systems. NetScaler SD-WAN is a simple and technological solution that allows companies to quickly and cost-effectively switch to SD-WAN technology, reduce excessive network complexity, and enable company employees to use applications from a data center or cloud environment.

Software Defined Networking (SDN) has been heralded as the long-term solution for dynamically provisioning and automatically configuring network resources as applications are deployed. SDN, though, has moved beyond theory to practical reality, as open standards and growing interoperability among vendors are driving rollouts of new capabilities.

The ongoing virtualization of data center infrastructure and integration of cloud computing resources make it imperative to be able to dynamically shift and monitor workloads across those environments. As data center networks have grown to encompass thousands of devices, existing architectures have proven inadequate for rapid deployment of applications and unable to keep up with the agility requirements of today’s business environment.

This paper reviews the state of SDN today, including key factors in its evolution. OpenFlow It also reviews the development of standards such as and the more recent OpFlex open policy protocol that complements it. Cisco Citrix It will then look at how the Application Centric Networking model from has developed to create a more complete solution for SDN that combines L4 — 7 services from using the NetScaler ADC.

While virtualization of compute and storage have made those infrastructures more efficient, the network has not kept pace, leaving data centers struggling to leverage such advances. Proprietary legacy networking solutions make it difficult for organizations to adapt new technologies needed to create innovative services and are barriers to achieving the full potential of enterprise cloud computing.
