Big Data Distribution Across The World

PDF_iconProduct description

The research is defined within the BitBooster project.

Background and motivation:

The Internet was born in 1969 when the first data transmission between two computer along the distance 600 km was held. It was the first step into the data transmission world. The Wide Area Network has been developed with time. And distances between communication nodes have been correspondingly increased. For now, the main communication problem is not just sending of data. Today is more important to transmit it reliability on a high rates according society needs
There are two well-known transport protocols that are widely used for data transmission: TCP and UDP. The principle difference between them is the reliability. TCP is a reliable transport protocol that is widely used for data transport in IP networks and sub-networks. It is suitable for transmission of data streams with guaranteed integrity, reliability and checking of delivery. This protocol is widely spread however it has some significant drawbacks. Taking into account the fact that this protocol was created almost 40 years ago easy to understand that it was developed for completely another networks as we are using now. Data at that time were transmitted by means of TCP via local networks where:

  • RTT was up to 20 ms;
  • capacity was ones and tens of megabits per second.

For sure, the size of these data and required distances were extremely less than nowadays. Thus, communication industry faced main problems: how to transmit Big Data through LFP (Long Fat Pipes) e.g. between continents and how to avoid congestions in such a connections in more effective manner. Concept of the TCP protocol cannot fill fully all needs in data transmissions of modern society.

In FILA group it was decided to investigate new ways for data transition to consume existing network resources more effectively even if the quality of legacy infrastructure is poor. There is an idea to insert the algorithms for available bandwidth analyse in the communication channel during reliable data transmission. Such approach will allow avoidance of congestion even before the congestion happened. Means this “congestion prediction” the effective bandwidth utilisation will be achieved. Also the transport protocol with this algorithm will have quick adaptation to changing of a bandwidth in a connection. FILA group developed alternative protocol. Reliable Multi-Destination Transport (RMDT) is a point-to-multipoint data transport protocol, which provides reliable multi-gigabit Big Data distribution across the world. It works in any IP-based networks and can handle high packet losses as well as high RTTs and jitter. 

Unique RMDT protocol features include:

  • Multiple recipients within a single session
  • Reliability on the full rate over WAN
  • End-to-end 10G communication (1x10)
  • Efficient system resources consumption
  • Legacy IP infrastructure
  • Suitable for streaming

RMDT protocol can be used in WAN networks in order to assure maximum bandwidth utilization. It is resistant against high losses, RTT and delay jitter. Our researches demonstrated that it is capable to provide up to 950 Mbps per receiver in presence of 2 % losses and 300 ms RTT. Due to use of the patent pending ABC algorithms, the protocol is able to deal with very aggressive cross traffic with high efficient rate adaptation, that moves RMDT to the next level of intelligence in comparison with competitors.

Under the same conditions competitor's multi destination protocols perform more than 5-20 times slower in comparison to RMDT. FILA group was present in the CeBIT’2017 and illustrated the achieved results on the example of transmission of the FullHD video steaming with data rate up to 10 Gbps (by means of data transmission stream up to 1 Gbps each) and losses of up to 4%.
