Welcome to World Multicast Inc.
Before the crash of the “Technology Bubble” a tremendous amount of research was being done the Multicast area. World Multicast was well beyond the research phase and was a leader in Mulicast Solutions. In fact, World Multicast had a developed Secure Reliable Multicast technology in 2001. After theTechnology crash, World Multicast was the only company that kept on researching Secure, Reliable, and Accountable Multicasting solutions. We called it SMART Multicast.
We stayed ahead of our competitors because our patented Reliable Multicast technology. The other commercially available Reliable Multicast schemes re-multicast missing data to all receivers. Because different receivers would be missing different packets of data, this type of solution is inefficient. Current Reliable Multicast research has not taken security into consideration. The way to solve Multicast’s problems was by engineering a Multicast overlay that adds Security, Reliability and Accountability simultaneously. World Multicast Inc’s SMART secure reliable multicast technology is that solution, patented by three United States Patents.
By using a Secure, Reliable, and Accountable Multicast from World Multicast which is point-to-multi-point, your business could escape the exponential costs of bandwidth consumed by current point-to-point technology.
Recognizing that our work on the computer programming necessary to make Multicasting available to all end-users was only two-thirds complete on 01 April 2001, our research and business team decided to focus the bulk of our attention on technologies that could be marketed in the immediate future, notably our secure and reliable data transmission system, which derives from research that Ian Stewart was doing on battlefield uses of Multicast for secure military command and control. We realized, only incidentally, that this technology was ideal for secure and reliable business networking that transmits data from one point to many users. We use Multicast technology to transmit to a multitude of users, and for reliability, we combine our Multicast system with a back channel Unicast to order to individually rebroadcast of any “lost packet” of Multicast transmitted data.
Current communications technologies are providing substantial increases in bandwidth every year, increasing the capacity to move large volumes of data quickly. The incredible brawn and speed of these technologies are giving the businesspersons unparalleled control over goods and services and all but eliminating the barriers of time and distance. However, in light of the ever present, if not increased, pressure to reduce business spending, SMARTcasting (SMART Multicast) is an inexpensive, reliable, and secure, and accountable alternative to current broadband-based Unicast. SMART technologies must be utilized to adequately and wisely prepare your business in these competitive times.
We have been issued three patents on our SMART protocol technology.
Here is an explanation of why our Secure, Reliable, Accountable Multicasting is needed and why it is so important.
One of the easiest ways to understand the motivation for our product is to turn the clock back to when bright young minds were working on a method for computers of dissimilar brands to communicate. Back in those times, computers from Digital Equipment Corp, IBM, Hewlett Packard, and others could not communicate with each other.
Because of this lack of communication, developing a groundbreaking technology to inter-network dissimilar computers together was important. A group of computer engineers came up with the idea to have an “inter-networking message processor – IMP”.
This “IMPs”, as they were called, would relay packets of information based on the best route to that information’s final destination. The “IMPs” were given the brains to autonomously figure out the best route for the data. If there were a failure, the IMPs would then re-route the information to what they considered to be the best choice for the packet to be delivered to its destination. The protocol (set of rules) of the packets of information that the IMPs carried was called “Internet Protocol” commonly known today as “IP”. There was one very important problem with this system.
There was no guarantee that all of the packets would arrive.
The ability to connect different computers of dissimilar manufacture was impressive (to say the least), so the Defense Department, which had a lot of dissimilar computers to connect, invested some research money with a few wireless guys, Vint Cerf and Bob Kahn, who were trying to solve the problem of “IP packet loss” in radio communications. Building onto the earlier work of the “IMP”s creator’s and their “Internetwork Protocol” the Defense Department engineers engineered a solution was they called “Transmission Control Protocol”. The Internet of today is based on Transmission Control Protocol running on top of Internet Protocol or TCP/IP. TCP was built “on top” on the Internetworking Protocol (IP) or in other words TCP used the Internetworking Protocol as its base.
This type of building block development is now called “the Internet way”.
So what does this have to do with World Multicast?
The idea of an Internet Protocol transmission of one sender to many receivers was invented by Professor David Cheriton from Stanford University and championed at the Interent Engineering Task Force by Steven Deering. He called this new protocol (set of rules) “IP Multicast” (Internet Protocol Multicast). Cheriton proposed that packet information could be duplicated by the IMPs (now called routers) so that multiple receivers can tap into that same stream of information.
Here is the important point; The Cherition’s Multicasting Protocol is built on top of the User Datagram Protocol (UDP is an extended Interent Protocol (IP)), similar to TCP. Once again the designers of the Multicasting Protocol just as the earlier designers of Transmission Control Protocol (TCP) had said, “Packet loss is not our problem”. Cheriton’s Multicasting protocol had the same problem as the Internetworking protocol, not Reliable (in the Internet sense), not Secure, and no way to measure audience (Accountable). The same type of problem that the defense department had years ago when they commissioned a solution – Transmission Control Protocol (TCP).
The Multicast packet mouse was finding his way through the maze so to speak; however, there is no way to guarantee that that mouse had arrived.
This is the reason why World Multicast invented a Secure Reliable and Accountable way to Multicast on the Public Internet. World Multicast’s solution uses the underlying base of the Multicasting infrastructure already built. However, it adds on to the top of that structure a secure., reliable, and accountable method to implement communications.
SMARTcast is a way to send Multicasting Data-grams (packets) with Security, Reliability and Accountability. Our SMARTcast protocol guarantees the packets of information will arrive at their destination. If they do not, SMART will resend those packets based on where they are needed. SMARTCAST is the only tree based protocol that offers Security, Reliability and Accountability.
The dream of television on the Internet could not be achieved by the current Multicasting infrastructure and so we needed a Multicasting Infrastructure solution take care of the problem.
We at World Multicast are dedicated to finding Multicast solutions that are fully cost-effective. We will be continuing to build and patent even more exciting technologies as time goes on.
