Peer to peer dynamic network link acceleration

Abstract

A peer to peer dynamic network acceleration method and apparatus provide enhanced communications directly between two or more enhanced clients. The enhanced clients may comprise a front-end, a back-end, or both. In general, the front-end and back-end of the enhanced clients work in concert to translate data into an enhanced protocol for communication between the enhanced clients. The enhanced protocol may provide acceleration, security, error correction, and other benefits. Data from various applications may be seamlessly translated between a first protocol and the enhanced protocol, such that the applications need not be modified to use the enhanced protocol. The enhanced clients may automatically detect one another to establish an enhanced communications channel automatically.

Problems solved by technology

Unfortunately, the heterogeneous nature of the Internet makes it difficult for the hardware and software that implement the Internet to add functionality.

Implementing or modifying functionality in a lower layer protocol is very difficult as such changes can affect almost all users of the network.

Devices such as routers that are typically associated with infrastructure operate exclusively at the lower protocol layers making it difficult or impossible to implement functionality such as real-time processing, data compression, encryption and error correction within a network infrastructure.

Also by design, it is difficult to accurately predict or control the route a particular packet will take through the Internet.

As a result, however, a particular node or machine cannot predict the capabilities of the downstream mechanisms that it must rely on to deliver a packet to its destination.

A sending node cannot expect all mechanisms in the infrastructure to support the functions and / or syntax necessary to implement such functions as real time processing, data compression, encryption, and error correction.

For example, it is difficult if not impossible to conduct synchronous or time-aware operations over the Internet.

While each IP packet includes information about the time it was sent, the time base is not synchronous between sender and receiver, making the time indication inaccurate.

Packets are buffered at various locations through the Internet infrastructure, and there is no accurate way to ascertain the actual age or time of issue of the packet.

Hence, critical packets may arrive too late.

Infrastructure components responsible for sending the information between the sending and receiving processes do not analyze whether effective compression has been performed, nor can the infrastructure implement compression on its own.

Where either the sending or receiving process is incapable of effective compression, the data goes uncompressed.

This creates undesirable burden that affects all users.

However, FEC is not used within the Internet infrastructure.

This stems in part from the additional complexity, cost and management tasks that such capability would impose on the system hardware and software.

In practice there are multiple standards for real-time processing, encryption, compression, and error correction, and one or the other node may be unable to support the protocols of the other nodes.

For example, implementing error correction only between the sending and receiving nodes is only a partial solution, as the infrastructure components that operate at lower network layers (e.g., transport, network, data link and / or physical layer) cannot read error correction codes inserted at higher network layers.

Many e-commerce transactions are abandoned by the user because system performance degradations frustrate the purchaser before the transaction is consummated.

While a transaction that is abandoned while a customer is merely browsing through a catalog may be tolerable, abandonment when the customer is just a few clicks away from a purchase is highly undesirable.

However, existing Internet transport protocols and systems do not allow the e-commerce site owner any ability to distinguish between the “just browsing” and the “about to buy” customers as this information is represented at higher network layers that are not recognized by the infrastructure components.

In fact, the vagaries of the Internet may lead to the casual browser receiving a higher quality of service while the about-to-buy customer becomes frustrated and abandons the transaction.
