SD WAN simplifies branch office connectivity and management while improving application performance and network visibility. It uses software to direct traffic over multiple connection types, including broadband internet and private links. This allows traffic to automatically switch to the best available connection. SD WAN provides benefits like lower costs, easier management, and application-aware routing compared to traditional router-based WANs. Various vendors offer SD WAN solutions targeting enterprises, communication service providers, or as cloud-based offerings.

Software-Defined Wide Area Networking SD WAN © 2016 BROCADE COMMUNICATIONS SYSTEMS, INC. CONFIDENTIAL INTERNAL USE ONLY
Overview © 2016 BROCADE COMMUNICATIONS SYSTEMS, INC. CONFIDENTIAL INTERNAL USE ONLY • Purpose: ‒ Simplifies branch office connectivity and ongoing management, reduces hardware sprawl and significantly improves enterprise application performance while strengthening visibility and control for IT departments • Only 6% of people are using it, but it is expected that 70% will use • Differs from SDN because it is a technology you can buy or get as a managed service • VCPe- similar to a router but more powerful, VNFs (Virtual Network Function) • Prioritize network connection by application type or workload 2
Basics of SD WAN • Stems off of SDN (Software Defined Network) – Branch connectivity using a physical or virtual device (smaller than a router) • Rely more on broadband instead of private links – When broadband is weak and can’t handle the functions we need, SD WAN can switch over to private links only when needed (decreases costs) • Channels used: MPLS, wireless LTE, broadband (least to greatest) • SD WAN can reroute traffic based on the current state of the network. – IT tells it how to route the different traffic rather than us doing it manually (same job being done, but we don’t have to do the hard work, so it is less complex) – Reacts to changing network conditions automatically which saves IT time © 2016 BROCADE COMMUNICATIONS SYSTEMS, INC. CONFIDENTIAL INTERNAL USE ONLY 3
Constraints • SD WAN products vary and hence are not compatible, so if your WAN hardware must be replaced, it could result in an extra charge • ROI tool is not standard for all enterprises which makes it hard to understand how much SD WAN can save them © 2016 BROCADE COMMUNICATIONS SYSTEMS, INC. CONFIDENTIAL INTERNAL USE ONLY 4
