CISCO CCIE EXAM You must know about SD -WAN…(2)

CISCO CCIE EXAM You must know about SD -WAN...(2)

Third, we need to overcome some common misunderstandings and concerns about SD-WAN.

Too complicated

Network engineers who shun SD-WAN adoption because they seem to think that this technology will require them to learn some complex new programming languages.SD-WAN does not require you to learn some mysterious new programming languages. Cisco ccie .Because the SD-WAN sits on top of multiple WAN links and uses software-driven policies to automatically choose the best data transfer mechanism for each application, it masks complexity.exam

With SD-WAN, you can see the entire network. You are feeling it and seeing how it moves the connection.D-WAN keeps you ahead of the curve and you can keep up with service level agreements throughout your office. It will alleviate the huge burden on you.

too expensive

SD-WAN can be used as a SaaS, which is relatively inexpensive compared to custom DIY settings. Before you adopt it, you need to sit down and ask yourself: Can my team use a custom model to do this on its own, or can our business sign a service plan?

The SD-WAN firewall helps ensure that IT administrators gain the security and ability to identify thousands of applications on the network.cisco ccie exam.It simplifies the process of defining configurations and policies for everyone, giving IT administrators the control they need to get the job done.

A simple buy is a common obstacle because it is an upfront cost. The sooner you adopt it, the better you can master things and the more value you can bring to your business.

This is a killer

SD-WAN is designed to automate decision making and centralize operations while reducing errors.

The adoption of SD-WAN is inevitable, but it requires a change in mindset. Some engineers may have to take their work to the next level, but we still need to work for people who can design and implement the network. We still need someone who can use the software.

Fundamentally, this progress is just another advance in a series of technological leap. SD-WAN software doesn't do anything behind you, you still have control.

SD-WAN is just one of the tools you should consider.



Fourth, IT organizations need to consider the basic factors to consider when adopting or expanding SD-WAN

1.Save money

The economics of SD-WAN are reflected in avoiding expensive WAN link costs and increasing bandwidth efficiency. Since the average annual growth rate of WAN data is 20%, most organizations need more bandwidth to achieve high-speed communication to remote offices.cisco ccie exam.SD-WAN supports secure deployment of Internet links DSL, cable, Ethernet, wireless and other internet links, or in combination with expensive MPLS connections, and can replace expensive MPLS connections.On average, the internet connection provides 2 to 5 times the bandwidth of the same price MPLS connection, directly contributing to the return on investment of SD-WAN devices.

2. Improve reliability

SD-WAN allows traffic to pass through two or more separate WAN links. As a result, IT organizations can diversify their WAN connections by contracting with multiple communications service providers to ensure a more reliable connection to their remote offices.

3. Traffic identification and prioritization

Most organizations are rapidly moving from a hub-and-spoke WAN connection where all traffic is passed back to the central data center towards a direct point-to-point connection between the remote office and the cloud or SaaS application portal.SD-WAN enables IT organizations to set up applications and user-driven policies for priority and security. Cisco ccie exam.The SD-WAN recognizes the type of traffic going in and out of the branch and routes it directly to the correct data center.

4. SD-WAN support cloudy

Most IT organizations mix internal data centers, applications in the public cloud, and users accessing SaaS applications. SD-WAN solutions are able to identify and route cloud-based traffic.SD-WAN vendors have partnered with leading IaaS providers to accelerate communication between local sites. The SD-WAN solution identifies the IP addresses of most leading SaaS providers and routes traffic accordingly.

5. Management, Automation and Network Orchestration (MANO)

For most SD-WAN solutions, the intelligence of management, orchestration, and automation resides in a centralized data center or cloud.The management, automation, and network orchestration (MANO) consoles of centralized IT operators should be highly automated, but this often requires some learning process.SD-WAN MANO also faces some challenges to integrate into existing network and application management systems, but this is necessary for fully automated application performance management.

Cisco ccie exam Linux overview and history

      Cisco ccie exam Linux overview and history Simply put, the Linux operating system is a clone of the UNIX operating system, which was born on October 5, 1991 (the first time it was officially announced). It's the same as Microsoft's Windows, apple's MAC OS and android on mobile phones. Cisco ccie exam.Compared to ordinary people, Linux system may be relatively unfamiliar, and most of them are probably familiar with Windows system. Since the graphical interface of Windows is simpler and easier to use, Windows occupies more markets, and Linux systems are mainly command-line operations, which are more demanding for professionalism.Cisco ccie exam Linux systems are stable, secure, and have strong concurrency, so they are widely used in the server field. The professional servers are almost all Linux systems. Linux is open source, free, everyone can see the source code of Linux, you can use Linux for free. And the Linux kernel is short and lean, and some can only be a ...

Cisco ccie exam Introduction to the OpenFlow protocol

Cisco ccie exam Introduction to the OpenFlow protocol OpenFlow, a network communication protocol, belongs to the data link layer and can control the forwarding plane of the network switch or router, thereby changing the network path of the network packet. OpenFlow protocol background: Forwarding and control separation is one of the essential features of SDN networks.In the SDN network architecture, the control plane is separated from the forwarding plane, the management and state of the network are logically grouped together, and the underlying network infrastructure is independent from the application, thereby enabling the network to achieve unprecedented programmable, controllable, and automated capabilities.Cisco ccie exam. This makes it easy for users to build highly scalable elastic networks based on business needs. To implement the transfer separation architecture of the SDN network, a communication interface standard needs to be established between the SDN controller and the dat...

CISCO CCIE EXAM 5G and WIFI6, still can't tell? (1)

cisco ccie exam 5G and WIFI6, still can't tell? (1) Ⅰ. the opening: On October 3, 2018, the Wi-Fi Alliance officially incorporated WiFi based on the 802.11ax standard into the regular army and became the sixth generation WiFi technology. The WiFi specification was renamed, the standard 802.11n was renamed to WiFi 4, the standard 802.11ac was renamed to WiFi 5, and the new standard 802.11ax was renamed to WiFi 6. (Of course, the previous generation of 802.11b/a/g can be chased as WiFi 1/2/3) Not only changed the naming convention of WiFi, but also in the network connection of WiFi devices. Also all use the new UI icon. The icon will display the level of the WiFi network you are currently connected to through the most intuitive numbers. Wi-Fi is well known to us. Wi-fi has evolved from 802.11b in 1999 and has gone through five generations. The Wi-Fi Alliance announced the simplification of the name of the new Wi-fi to Wi-fi6 when it introduced the new generation of 802.11ax stan...
