WAN optimization options, from companies like Riverbed, Juniper, Blue Coat, Cisco, and others, free up bandwidth and speed up programs. Many companies have adopted WAN optimization or WAN acceleration as ways to improve the efficiency of their wide area networks. The two things that WAN optimization does best (disk-based compression and correcting the limitations of Microsoft’s CIFS protocol for file transfers) are not directly addressed by APN.
Here are some commonly used WAN optimization techniques:
- Deduplication – Eliminates redundant data transfer across the WAN by sending references instead of the actual data. By working at the byte grade, advantages are achieved in all IP applications.
- Compression: It is based on data patterns that can be represented much more efficiently. Ideal for stage-to-stage leased lines.
- Caching/proxying: It is based on human behavior, accessing the same information over and over again. Best suited for leg-to-leg leased lines, but more viable for Internet connections and VPN tunnels. Efficient use of web caching typically results in a 15-30% bandwidth reduction on WAN links.
- Protocol Spoofing – Groups multiple talker program requests into 1. Best suited for point-to-point WAN links.
- Latency Optimization: Local WAN optimizes request solutions with the client locally rather than sending the entire process to the server, providing a read-ahead and write-ahead mechanism to reduce delay over the WAN.
- Traffic shaping: controls the use of information according to the detection of specific patterns in the information and the authorization or denial of a given traffic. Best suited for both stage-to-stage leased lines and web connections. It can be hard to stay present with ever-expanding types of apps.
- Equalization – Makes assumptions about instant priority requirements based on data usage. Excellent choice for open, unregulated Internet connections and clogged VPN tunnels.
- Connection Limits: Prevents accessibility bottlenecks in routers and access points due to denial of service or peer-to-peer. More suitable for open web access links, can also be used on WAN links.
- Simple Rate Limits – Prevents 1 consumer from getting more than a fixed amount of information. It is best suited as a first intermediate effort to troubleshoot a congested web connection or WAN link.
Companies employ a wide variety of business networking applications. WAN optimization products accelerate these applications by compressing data and bandwidth, eliminating transmission redundancy, prioritizing information, streamlining, enforcing quality of service (QoS), and optimizing protocols and WAN options. By using WAN optimization appliances, the data transaction time between sites could be improved.
In the network-enabled enterprise scenario, optimization of region-wide network technology can substantially reduce the cost of infrastructure in remote locations by centralizing applications, server, backup, and data sources. storage in the information medium. Productivity and business continuity are increased through application acceleration along with data backup and WAN replication across the network.
