Question 1

What is WAN Optimization Software?

Accepted Answer

Wide area network (WAN) optimization software improves network congestion and latency by implementing bandwidth optimization techniques such as compression, caching, data deduplication, and network prioritization. Businesses and customers do not want to wait for their web page to load. WAN optimization, also known as WAN acceleration, can help by reducing the time it takes for information to travel from a company’s data center to its remote locations. Instead of buying new bandwidth, businesses can use WAN optimization software to provide fast internet applications despite increased traffic demand. This helps to ensure that customers do not get frustrated with delays.  
 Companies may determine which WAN optimization methods they want to use depending on connectivity, hardware locations, legacy application environment, and integration with other network types such as a local area network (LAN). Other times businesses may choose software-defined WAN (SD-WAN) which is a virtual WAN architecture. Regardless of the methods, it should address common issues such as latency, duplication, packet loss, and congestion in certain areas of the network. The end goal is to get faster data retrieval and web application performance for end users by improving network performance in real time.

Question 2

What are the Common Features of WAN Optimization Software?

Accepted Answer

The following are some core features within WAN optimization software that can help users to manage their network latency and congestion: 
 Bandwidth optimization: WAN optimization software tackles bandwidth latency and congestion by caching (save frequently used contents on local server), data deduplication (send hashes data instead of actual data), protocol optimization (reduce chatty protocol), path optimization (transfer data through a less congested connection such as Multiprotocol Label Switching (MPLS) or SD-WAN), location optimization (based on branch offices), and so on. Other more advanced optimization techniques may require buying hardware or advanced features from vendors.  
 Flexible deployment: WAN optimization solutions need to be easily deployed on major network virtual ware and hardware such as routers, servers, hypervisors, firewalls, and computers with high throughput (gigabytes level). Some solutions are also cloud ready or cloud natives. That means that they can be deployed in infrastructure as a service or platform as a service environment quickly. It should also be deployed in an SD-WAN environment.  
 IT control and visibility: A complete WAN solution should also monitor infrastructure resources since it needs to know resource availability to determine how to optimize the network. With full visibility, IT teams can set up service policies with the WAN optimizer to automatically manage their network based on availability.

Question 3

What are the Benefits of WAN Optimization Software?

Accepted Answer

Application acceleration: WAN optimization software uses traffic shaping to indirectly accelerate application performance and reduce bandwidth consumption. By revamping existing network connections, the software can increase performance several times for on-premises and cloud applications in hybrid environments. Based on the applications, the WAN optimizer can distinguish which network traffic is critical to the applications and select an optimal routing path for the data transfer. In the end, clients will experience a rapid and secure user experience with WAN optimization appliances. 
 Cost saving: This type of software could reduce bandwidth utilization significantly and defers costly network bandwidth upgrades. The percentage of savings varies based on the infrastructure. 
 Ease of management: IT staff can designate custom policies and alerts to better manage their network performance. IT projects that heavily rely on WAN and data centers can be managed in a centralized platform. Problems will be resolved faster with high visibility into the application network and centralized dashboard.
