A peer to peer dynamic network acceleration method and apparatus provide enhanced communications directly between two or more enhanced devices, such as 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.

The present invention relates to composite materials for tire, specifically to composite materials of tire sidewall rubber. A preparation method of the composite materials comprises the following steps of: plasticating rubber in an internal mixer, adding other component except for the sulfur powder and the accelerator to blend, lifting ram piston at 120125 C., discharging rubber at 150160 C. to obtain rubber compound, then mixing the rubber compound with the sulfur powder and the accelerator in open mill, rolling for 45 times and milling for 58 times to obtain product. The composite materials of the present invention not only meet the requirements of basic mechanical properties of the sidewall rubber, but also obviously improve thermo-oxidative aging resistance and ultraviolet aging resistance of the sidewall rubber, and thereby effectively prolong the service life of the tire.
