SD-WAN (Software-Defined WAN)

FatPipe pioneered the concept of Hybrid WAN/SD-WAN and provides great focus to SD-WAN and advanced hybrid WAN functionality. With FatPipe, you can aggregate multiple WAN links, perform load balancing for inbound and outbound traffic, perform dynamic path selection, carry out policy-based management, accelerate traffic with WAN optimization, augment last mile connectivity, eliminate the need for ISP cooperation in multi-carrier network redundancy, and have full control over your WAN links.

Organizations implement SD-WAN to establish a software-defined overlay network that operates independently of the carrier or the physical infrastructure beneath it. This network overlay is often used to improve network performance and reliability. Additionally, because a SD-WAN is independent of the underlying network, remote sites can quickly and easily be provisioned using the locally available bandwidth.

Challenges

  • MPLS Cost Constraints: Traditional MPLS connections are often expensive, especially when scaling for cloud-based services and increasing traffic demands. SD-WAN lets you overcome MPLS cost constraints and cloud connectivity issues with inexpensive broadband connections.
  • Network Complexity: Traditional WAN architectures are often cumbersome to manage, especially when integrating new equipment or adapting to evolving business needs. SD-WAN simplifies network complexity through a combination of hybrid WAN designs and an increasingly cloud-centric solution. Systems can be adapted to changing business needs while new equipment and gateways can be incorporated into remote sites from a central location.
  • Network Availability: Maintaining uptime for individual links has consistently been challenging, and when combined with impaired links, the complexity of the issue increases significantly. FatPipe solutions with unique features address this challenge effectively.
  • Public Network Unpredictability: Traditional networks lack the ability to adapt dynamically to changing network conditions, often leading to bottlenecks, increased latency, and poor performance for critical applications. SD-WAN can adapt to routing decisions based on real-time public network diagnostics that detect latency, bandwidth constraints, bottlenecks and more. High-priority traffic is transmitted across faster connections while less reliable links are reserved for less important data.
  • Application Awareness: The problem of limited application awareness in traditional networks is resolved with SDWAN Application steering , QoS and Application traffic optimization.

Benefits

  • Eliminate Backhaul for Secure Cloud and Data Center Traffic: SD-WAN eliminates the need to backhaul traffic for security screening with a design that's compatible with in-house data centers, public or private clouds, SaaS solutions and more.
  • Cost-Effective, High-Bandwidth Connectivity: SD-WAN gives you the advantage of replacing expensive connections with limited bandwidth with more affordable connections with greater bandwidth.
  • Simplified Migration to Hybrid Network Architectures: Migration from private to hybrid (public/private) network for branch connectivity is made easy.
  • Customizable Security Configurations: Flexible network customizations are available as per security requirements.
  • Adaptability to Branch Office Needs: SD-WAN can adapt itself to the evolving needs of branch offices.
  • Optimized Cloud Application Performance with Direct Internet Access: Direct internet access enhances SaaS and IaaS traffic, as well as the performance of other cloud applications locally protected by security measures at the branches.
  • Overcome the Limitations of Broadband Connections: SD-WAN's unified platform that consolidates various control functions lets you overcome the security, latency and performance limitations of broadband connections, especially those of mission critical operations while simplifying manageability regardless of the scale of operations.
