Sunesis Networks' WAN Optimization technology offers the highest performance level of WAN Optimization and optimization available using patented and patent pending technology. With Sunesis WAN Optimization, you can significantly boost your Wide Area Network performance. This is possible through acceleration of your applications, better utilization of your current WAN infrastructure that would ultimately result in saving you thousands of dollars a year on additional hardware, software and bandwidth costs. Sunesis WAN Optimization appreciably increases WAN utilization, providing effective use of WAN bandwidth by caching/compressing that sharply reduces redundant data on a WAN.
Sunesis is the first to market and the only provider of WAN Optimization and optimization technology that can work across multiple WANs. Not only can you optimize your WAN traffic, you can achieve the highest level of WAN redundancy and reliability. Additionally, unlike other WAN optimization/acceleration products that provide WAN caching at the file level, Sunesis WAN caching works at the file as well as the byte level. Smaller granularity results in greater levels of detected redundancies, and more de-duplication and less retransmission, giving you the highest level of WAN optimization available.
With Sunesis WAN Optimization, you can measurably increase productivity levels as it reduces response time for interactive applications, helps speed-up large data transfers between your headquarters, branches and data storage and/or disaster recovery sites, thereby increasing speed of data transfer between sites.
As reliance on the WAN as a major instrument of business grows at the rate it has over the past few years, its importance has become a prime factor. All business pay close attention to the health of the WAN. The cost of bandwidth has fallen significantly over the last 20 years. Most businesses have increased bandwidth to match needs. Unfortunately, increasing bandwidth alone will not solve issues of transference of data due to the inherent nature of TCP/IP protocol itself. Due to this, WAN Optimization has steadily gained importance.
The definition of what WAN Optimization is varies greatly depending on whose point of view is considered. However, it can be said that WAN Optimization is any action or activity that improves the operation of the WAN such that the WAN Operational goals are met
True WAN Optimization applies optimization techniques across all connections to the WAN. WAN Optimization done only on a single connection is in reality line optimization. True WAN Optimization works using a variety of techniques that are copacetic over all connections. Some of the techniques are: Load balancing, QoS, Deduplication, Caching, Compression and transference algorithms. Sunesis Networks has a unique solution to WAN Optimization. Sunesis Networks adroitly combines load balancing and redundancy with WAN Optimization leading to optimization across all WAN connections. The upside to this is that, a single Sunesis WAN Optimization unit can be used to optimize data transference across all connection but failover in case a connection is down. Thus data will flow unimpeded.
Load Balancing is a basic tenet of WAN Optimization. This ensures the loads are balanced across all connections in a bidirectional fashion. Load balancing also constantly checks the health of each line and shifts loads away from lines that are not working or down. Different load balancing algorithms are used to spread the load. They depend on circumstances and vary, some of them are: round robin, weighted, fastest route, least latency, on demand, and spillover.
Quality of Service commonly called QoS is a powerful tool in the WAN Optimization arsenal. It gives network administrators the ability to have granular control over the flow of data across the Wide Area Network. QoS enables the reservation of bandwidth for data or activities that are deemed important by the network administrator. All other data are transferred on a "best effort" basis. Deduplication is a significant part of optimization. During the transference of large data blocks, it is not unusual for duplication to occur. Duplicate data consumes bandwidth and has a direct effect on the functioning of the WAN. The deduplication process checks data and determines if it has been sent before. If it has, data is not transmitted.
Compression has a direct bearing on bandwidth requirements. All data cannot be compressed to the same extent. For example a jpeg file is pre-compressed and compression algorithms will have no effect. However, Word documents, Excel files, etc. can be compressed multiple times of their original size on the fly and be delivered swiftly using WAN Optimization which eliminates high bandwidth requirements.
Caching reduces time taken to access data. For example, if a large corporation with operations in hundreds of places, issues an all employee bulletin, the demand on the WAN is significant. As each employee tries to access the same information, the stress on the system to accommodate all requests is very significant. WAN optimization uses caching to dramatically reduce loads as well as decrease the time it takes to access. When an employee of a branch first accesses the bulletin, WAN Optimization stores a copy in local cache. The next time a request is made for the same information, it responds to the request at its best from the local cache thus reducing demand on WAN bandwidth & server load. The optimization system also ensures the data saved locally is up-to-date. If changes have been made on the source data, only those changes are sent across the WAN rather than the whole.
WAN Optimization has become an important component in the administration of an efficient network. The use of such techniques is bound to grow for the foreseeable future.
