How Does WAN Optimization Work?
- WAN optimization works to overcome latency, increase network, and minimize packet loss, and throughput and accomplishes this via an array of complementary WAN optimization techniques.
- Window scaling increases the sending window, enabling more data to be transferred before an acknowledgment is received.
- By tackling difficulties such as network latency, capacity restrictions, and packet loss, WAN optimization improves network performance, especially in contexts where data must travel great distances.
- These techniques rely on TCP acceleration, data compression, deduplication, and forward error correction.
WAN Optimization vs WAN Acceleration
WAN optimization is a process to increase the efficiency of data and backup processes, and application performance, and ensure important information is delivered and stored securely in remote locations. Organizations can save money by reducing the data quantity sent over the WAN. WAN acceleration is accomplished by using several strategies, including caching, compression, and data duplication. When bandwidth demand initially began to outpace available bandwidth in the early days of enterprise-wide area networking, WAN optimization technologies were developed. WAN Optimization can significantly increase productivity levels by reducing response time for interactive applications and speeding up large data transfers between your headquarters, branches, and data storage and/or disaster recovery sites, thereby increasing data transfer speed between sites.
