In today's hyper-connected digital landscape, the performance of business-critical applications is not just a technical concern; it's a strategic imperative. Poor application performance can directly impact end-user productivity, customer experience, and ultimately, a company's brand perception. Faced with the unpredictable nature of the Internet and other public networks, organizations are increasingly turning to Software-Defined Wide Area Networking (SD-WAN) as a solution to ensure optimal performance across their cloud-connected networks.

Improving Application Performance with SD-WAN

SD-WAN offers a plethora of capabilities aimed at enhancing application performance, thereby bolstering overall business productivity. Here's how SD-WAN achieves this:

  1. Application-Aware Traffic Management: SD-WAN empowers administrators to identify network traffic based on various parameters such as application, user, or source/destination and treat it differently. Through the intuitive policy engine of an SD-WAN controller, administrators can create rules specifying the appropriate network path for each application. This enables SD-WAN devices to intelligently route traffic, optimizing performance based on specific application requirements. For instance, critical applications requiring high bandwidth and minimal latency can be prioritized, ensuring seamless user experience. Conversely, lower priority traffic, such as Internet browsing or file backups, can be routed through cost-effective connections without compromising performance.

  2. Dynamic Traffic Steering: SD-WAN monitors the health of each network link using metrics like latency, packet jitter, and dropped packets. In the event of congestion or other network issues, SD-WAN can dynamically steer traffic away from congested links, rerouting it through alternate, healthier paths. This proactive approach ensures consistent application performance even in the face of network challenges, mitigating potential disruptions and bottlenecks.

  3. Synergy with WAN Optimization: While SD-WAN excels at steering traffic around congested links, WAN optimization complements its efforts by improving performance across these links. By leveraging techniques like deduplication and compression, WAN optimization reduces the number of packets sent across the WAN, thereby decreasing bandwidth requirements and enhancing overall network efficiency. Moreover, WAN optimization addresses latency issues by optimizing protocols, particularly beneficial for applications spanning long distances between servers and clients. By combining SD-WAN and WAN optimization, organizations can achieve optimal performance across their network infrastructure.

Balancing Security & Performance

One of the key considerations for organizations adopting SD-WAN is striking the right balance between security and performance, especially at edge locations. SD-WAN offers several features to address this challenge:

  • Perimeter Firewall and VPN: Many SD-WAN appliances come equipped with a perimeter firewall, bolstered by VPN capabilities, offering adequate security for edge locations.

  • Granular Traffic Control: SD-WAN devices can identify network traffic based on source/destination, application, and users, enabling administrators to route traffic according to centrally-defined security policies.

  • Direct Internet Access: Connections with trusted SaaS providers utilizing encrypted transmission can bypass traditional backhauling, enhancing performance without compromising security.

  • Centralized Security: Traffic to/from untrusted websites or confidential network traffic can be routed through a central access point with robust security measures in place.

  • Cloud-Based Security Services: Alternatively, organizations can leverage cloud-based security services to ensure comprehensive protection for external network traffic.

Optimizing WAN Performance

In addition to enhancing application performance, WAN optimization plays a crucial role in improving network efficiency and user experience. Organizations can leverage WAN optimization in the following scenarios:

  • High Latency: WAN optimization proves particularly effective in scenarios where high latency due to long distances between end users and application servers impacts performance.

  • Bandwidth Constraints: In situations where bandwidth is limited or network congestion is prevalent, WAN optimization techniques can alleviate these constraints, ensuring smooth data transmission.

  • Chatty Protocols: WAN optimization excels in optimizing the performance of applications relying on "chatty" protocols like SMB and MAPI, enhancing data transmission efficiency.

Closing Visibility Gaps & Proactive Performance Management

While SD-WAN and WAN optimization significantly improve performance, ensuring consistent performance requires proactive monitoring and management. In the next chapter of our series, we will delve into how IT teams can close visibility gaps with monitoring tools, providing end-to-end visibility needed to identify and troubleshoot performance issues proactively.

Wrap

SD-WAN emerges as a transformative force in the realm of networking, offering unparalleled capabilities to enhance application performance, optimize WAN efficiency, and balance security and performance requirements. By leveraging the synergies between SD-WAN and WAN optimization, organizations can unlock peak performance across their network infrastructure, driving business agility and ensuring a seamless user experience in the digital age. Stay tuned for the next installment of our series as we explore advanced strategies for proactive performance management with SD-WAN.
