Breakthrough claimed in WAN bandwidth optimisation

25 September 2002 Computer/Embedded Technology

With the spiralling cost and increasing constraints associated with wide area network (WAN) bandwidth in South Africa, Source Consulting has announced a solution that is said to provide instant capacity gains of up to 10 times by eliminating the transmission of repeated data patterns. Unlike conventional data compression methods, the solution uses next-generation molecular sequence reduction (MSR) technology developed by Peribit Networks in the USA.

MSR is Peribit's groundbreaking DNA sequencing-based technology that is a spin-off from the Human Genome Project. The key strength of MSR technology is its ability to find variable sized repeating patterns anywhere in the data stream, across multiple packets, applications or sessions. The benefit is the ability to reduce traffic across WAN links by up to 90% by swapping labels for redundant blocks of IP data.

MSR adaptively learns the patterns that occur most frequently in the data and assigns to each pattern a unique label. MSR then uses this table of patterns to encode the data stream in a highly efficient format by replacing each instance of the pattern with the corresponding label. The numerous noninformative redundancies that waste network resources are thus stripped from the data stream before they are transmitted across the network's links.

According to Jack Ward, a director of Source Consulting, repeated noninformative data patterns typically constitute between 70-90% of all network traffic. These repetitions waste precious network resources and severely degrade network efficiency and application performance.

"MSR supports a wide range of network applications and protocols to allow users to realise immediate decreases in WAN expenses while increasing overall network throughput," he says. "MSR is also capable of setting traffic priorities for mission-critical applications and offers significant reductions on voice over IP traffic - something that cannot be realised with conventional compression techniques."

Source Consulting has released a new Gigabit Ethernet product from Peribit, the SR-55 Sequence Reducer, said to be the only product that gives IT managers the choice of preserving and honouring QoS settings already established elsewhere in the network, or that lets the Sequence Reducer automatically set essential QoS priorities for various traffic flows.
