WAN Optimization Technology

The use of optimization technology in shared wide area network environments such as Internet Virtual Private Networks (VPNs) and Multiprotocol Label Switching (MPLS) enables to avoid packet delivery issues. This is crucial to businesses that are transmitting business-critical data over the public network. WAN optimization technology encompasses component techniques including deduplication, CIFS proxy, Wide Area File Services (WAFS), Hypertext Transfer Protocol over SSL (HTTPS) Proxy, bandwidth management, Web caching, multicasting, and Forward Error Correction (FEC). The unique functions of these WAN optimization techniques would give an insight of what companies expect and how Corporate organizations implement them for efficient and continued operations.

Deduplication is the technique of eliminating redundant data transfer over the Wide Area Network, which is effected by sending references rather than the actual data. This is useful for IP applications as it works on the byte level. Compression is mostly suited for point-to-point leased lines. It depends on data patterns, which can be efficiently represented. Caching/Proxy will access the same data repeatedly and is reliant on human behavior. It is most suitable for point-to-point leased lines but can also be applicable for VPN tunnels and Internet connections. Connection Limits helps routers and access points to access through IP traffic that is caused due to denial of service. This is most suitable for open Internet access links, but can also be used on WAN links. Simple Rate Limits allows a single user to receive only a specified amount of data. It is beneficial for avoiding gridlocks in Internet connections or WAN links. The WAN optimization technique Protocol Spoofing is used for clustering multiple requests from communicative (chatty) applications into a single component. It is most suitable for point-to-point WAN links. Traffic Shaping is a technique where data usage is controlled and specific traffic is allowed or disallowed based on identifying specific data patterns. This is best suited for both Internet connections and point-to-point leased lines. Another good WAN optimization technology is Equalizing, where the immediate priority is determined based on data usage and estimating from the same. This is best suited for clogged VPN tunnels and wide open unregulated Internet connections.

Wide Area Network optimization technology is widely used by companies as they provide multifaceted benefits. It is capable of delivering centralized applications with the speed of Local Area Networks (LANs) to remote users, and also maintaining transparency and security in branch locations. Bandwidth usage can be optimized along with consolidation of expensive remote (branch) office servers, backup infrastructure, and storage into data centers. Through application of WAN optimization techniques, branch storage can be consolidated, thereby maximizing regulatory compliance and data protection. The branch or remote office backup applications can also be accelerated. In the network, application data flow visibility is increased.

This technology includes in scope traffic management methods (for prioritizing mission-critical applications during traffic peaks), TCP and protocol-specific acceleration algorithms (for minimizing network latency), Pre-fetch mechanism in file and object caching (for accelerating response time), Data reduction combined with protocol redundancy removal and compression (for improving network throughput). Data Redundancy Elimination (DRE) and Transmission Control Protocol (TCP) Flow Optimization (TFO) are two major benefits provided by using WAN optimization technology. DRE and compression together improve efficiency and eliminate unnecessary consumption of bandwidth. TFO technique improves performance level and efficiency in WAN environments through optimization of TCP.

The WAN marketplace is booming with technologies and technology gadgets of all kinds and suited for diverse specifications. WAN optimization solution suites are offered by premier technology vendors, which enable a stable WAN infrastructure. Basic constraints such as WAN latency can be substantially reduced once data is streamlines and supporting techniques are implemented. The future of WAN optimization management is one of integration of technologies with business policies, pattern-matching potentiality, automatic and correlated protocol analysis. As technology advances, the management complexities can be overcome easily and yield high performance in networks. The evolving technology market is also looking at integration of routing and WAN optimization technologies. IT managers are seeking to advance network capabilities through aggregation of different technologies, which is bound to boost network performance.
