WAN acceleration, also referred to as WAN optimization, is a collective term for various techniques aimed at enhancing the speed and efficiency of data transfer over a Wide Area Network (WAN).
WAN acceleration improves issues like network congestion and latency by implementing bandwidth-protection technologies such as compression, caching, data deduplication, and image optimization. Unlike application acceleration, WAN acceleration focuses on optimizing the network rather than the application itself (although there may be some overlap in objectives or approaches with web acceleration). However, WAN acceleration is sometimes undertaken as part of efforts to improve application performance, particularly for scenarios like mobile access, remote work, or e-commerce applications, which generate increasing amounts of traffic. This allows organizations to provide fast and responsive access to applications and data, even amidst growing demands.
Everyone wants quick access to the information they need. WAN acceleration or optimization helps achieve this by streamlining network traffic and optimizing bandwidth, enabling users to access vital information and tools without frustration caused by delays.
Various WAN optimization techniques target issues such as network latency, congestion, duplicate data transfers, or protocol inefficiencies. These challenges are particularly concerning for organizations with networks spanning different regions or legacy applications designed for use within a Local Area Network (LAN). WAN acceleration enhances user experience by optimizing bandwidth, bringing content closer to the client, and ensuring faster access to resources like collaboration platforms, CRM databases, portals, and applications. As a result, users can retrieve data more quickly, and application performance is significantly improved.
