Q. 

Why does a network service provider need the Divinator?

A. 

ISPs constantly struggle the bandwidth costs and traffic congestion. File sharing websites like Rapidshare and 4shared as well as video streaming have already captured a significant share of available bandwidth and are expected to grow exponentially. As this growth explodes, operational costs will skyrocket, and profits will dry up Additionally, congestion that results from this high utilization will further impair Quality of experience to all customers. The Divinator is the ideal solution for these issues.

The Divinator:

• Dramatically reduces the utilization of existing lines and delays the future lease of new expensive lines.
• Solves issues involving file sharing sites (such as 4Shared and RapidShare), video streaming, and high definition content, and improves Quality of Experience , as the line is no longer congested

Q. 

What types of data does the Divinator support?

A. 

The Divinator™ is based on patent pending data block caching and compression technology, which is completely protocol neutral. It optimizes IP packet payload regardless of content, protocol or application. This makes it the ideal solution for HTTP data (including file sharing applications and video streaming), P2P, and any kind of protocol.

Q. 

Why is the Divinator™ better than any other solution?

A. 

The Divinator is based on patent pending Data Block Caching and Compression technology, which provides the following key advantages:

• Data Block Caching and Compression is the only solution designed to solve the problems of today, and be prepared for future problems such as high bandwidth utilization by file sharing web sites (RapidShare or 4Shared), the use of Usenet, video streaming, high volume HTTP content, and high definition content.

• Comprehensive solution: Data Block Caching and Compression is unaware of the protocol carrying data. It optimizes IP packet payload regardless of content, protocol or application, and as a result, it supports eMule, Bitorrent and other P2P protocols

• Minimal maintenance: unlike traditional web caching, Divinator only requires minimal maintenance.

• Performance: Divinator™ efficiently handles hundreds of thousands of simultaneous TCP sessions while filtering the relevant sessions for optimization. This is achieved through highly sophisticated packet routing algorithms and optimal memory structures.

• Simple implementation: Deployment of the Divinator™ is straightforward and requires minimal configuration, as most of the job is done automatically by Divinator™ technology which automatically and continuously learns, adjusting itself to the type of traffic on the specific link.

• Legal: Divinatior™ partitions data into blocks and stores them on the Divinator™ hard disk. Unlike a cache, it is impossible to extract an original file from the Divinator's hard disk. The only way to extract data from the Divinator™ is through a live session between two Divinators. This is in contrast to existing cache solutions that serve as a source of the transmitted file, thereby exposing the cache-owner to copyright infringement liabilities. Moreover- this technology assures total net neutrality while performing caching / compression.

Q. 

What is the different between P2P Caching, Web Caching and Divinator™?

A. 

P2P caching is a system that stores entire files transferred through P2P. it is only located on one side of the line, and it sends the file from a local cache. It does not provide an answer to the current challenges that face ISPs today (mainly sharing web sites like 4Shared and RapidShare)
Web caching does the same for web pages and content, it requires heavy maintenance and does not provide an answer to the current challenges faced by ISPs (mainly file sharing web sites like 4Shared and RapidShare, video streaming, high definition content, and dynamic content.
Divinator™ utilizes a combination of compressing and caching. It identifies small data blocks within packets, not files. It then compresses them, sends them off, then decompresses them at the ISP destination. This makes Divinator the ideal solution for issues involving massive amounts of HTTP traffic (such as RapidShare and YouYube).

Q. 

Which protocols does Divinator™ support?

A. 

: Divinator™ was designed to be protocol neutral. Therefore it supports HTTP, and all multimedia and P2P protocols. Moreover, Divinator™ automatically integrates support for any future IP protocol, without need for upgrade.

Q. 

Where is the Divinator™ located in the network?

A. 

Typical deployment includes a Divinator™ on each end of a high cost communication link. This provides a complete point-to-point solution. However, the Divinator™ can additionally be deployed in a variety of different configurations to support full-duplex or half-duplex bandwidth optimization. The Divinator™ can function as a gateway to manage all network traffic. It can also be deployed next to an existing content switch/redirector, and configured to manage only selected types of traffic, directed to it according to the ISP's redirector configuration. Furthermore, it can also be deployed as a bridge on each side of a high-cost link. Divinatior™ can also be deployed to support mesh network bandwidth optimization, resulting in significant traffic reduction.

Q. 

Does the Divinator™ require any changes in the network topology?

A. 

No. The Divinator™ does not require any topology changes. Deployment of the Divinator™ is straightforward and requires minimal configuration, as most of the job is performed automatically by caching compression technology, which automatically and continuously learns and adjusts itself to the type of traffic on the specific link.

Q. 

Does the Divinator™ have an automatic fail-over mechanism?

A. 

Yes. The Divinator™ is a robust and safe system with built-in mechanisms to provide automatic fail-over, such as bypass capabilities. When a malfunction occurs, the Divinator™ informs the switch it is no longer available. At all times and in any case, all traffic will be forwarded without delay.

Q. 

Can the Divinator™ perform web caching?

A. 

Yes. Because Data Block Caching and Compression technology is unaware of the protocol carrying data, it optimizes IP packet payload regardless of content, protocol or application, including Web content!

Q. 

How does the cache algorithm works?

A. 

Data Block Caching and Compression is typically deployed on each end of a high cost communication link. The Divinator™ on one side receives streams of incoming communication from the local network and reduces its volume through unique packet caching. The reduced load is then transferred over the high-cost, high-speed link. On the other side, a second Divinator™ receives the reduced communication volume and then reconstructs the original streams for transmission over inexpensive local networks. The Divinators can be located on the two ends of a physical communication link or they can be installed on two sides of an Internet route

Q. 

What kind of switches work with the Divinator™?

A. 

One of the Divinator's advantages is that it does not require the usage of Layer 4/7 switch; as a result, a layer 3 switch is the typical choice. In any case, the Divinator™ system is compatible with all leading hardware. This enables full and seamless integration, reliable redirection, continuous monitoring, and load balancing of the system.

Q. 

What are the delay costs of Divinator™?

A. 

Divinator causes no more delay than an ordinary switch in the network.
If data is not relevant for caching and compression (for example, VoIP), Divinator functions like a router, with no writing to the disk. The delay is redundant (0.2 millisecond, can reach 0.3 millisecond during peak hours).
If data can be cached/compressed, then all activity is conducted in the background. The speed of data transfer is actually accelerated, due to caching/compression. Which in the end means there is no delay, and in fact data transfer is actually accelerated.

Q. 

How does the Divinator™ influence the end user experience?

A. 

Using Divinator™ allows the network to function more efficiently. Once employed, lines to the outside world are no longer congested. Furthermore, the network is no longer congested by rich media traffic. This has been a growing problem for ISPs and users. The result is far better performance for end users, which enables ISPs to provide additional value-added services to customers such as voice over IP and virus protection, far more efficiently and with improved performance.

Q. 

How many concurrent sessions can one Divinator™ handle?

A. 

The Divinator™ can handle several million concurrent sessions. By not needing to conduct deep packet inspection, valuable CPU and memory resources are conserved. This results in the ability to handle much greater traffic in both volume and number of sessions as compared to solutions that are protocol aware.

Q. 

What kind of management abilities does the Divinator™ have?

A. 

The Divinator™ comes with a web management interface that enables you to control and monitor Divinators both locally and remotely. In addition to the web interface, you can control and use the Divinator through SNMP, Telnet and SSH.

Q. 

Does the Divinator™ comply with legal regulations?

A. 

Data Block Caching and Compression partitions data into blocks and stores them on the Divinator™ hard disk. The Divinator is unaware of the content or application it processes. Unlike a cache, it is impossible to extract an original file from the Divinator's hard disk. The only way to extract data from the Divinator™ is through a live session with the original source of the content between two Divinators. This is different from caching solutions that serve as the source of the transmitted file, thereby exposing the cache-owner to copyright infringement liabilities. Moreover- this technology assures total net neutrality while performing caching and compression. This makes Divinator™ a valuable tool for communication service providers that want to avoid potential liabilities.
