Abstract (eng): | Due to growth of the Internet, the number of devices increasing and the structure of networks becoming more complex, the problem of time delays during information transmissions has arisen. In environments with long transmission delays modern protocols may become inefficient or even useless. Delay-tolerant Networking (DTN) is one approach that allows to solve the problem of long transmission delay times. In the thesis, an approach to web access in such networks is proposed. The problem of data transmission in the networks with long delays is considered. Special methods exist for data transmission in computer networks. But traditional data transmission protocols do not work well in networks with long delays, e.g. when transmitting over long distances, such as in space, or when connectivity may be disrupted, such as in mobile networks. It is necessary, therefore, to replace TCP and to change the existing web protocol (Hypertext Transfer Protocol - HTTP) in order to allow HTTP data transmissions in DTN environments. In the thesis, HTTP is analyzed and an adaptation of HTTP to DTN environments, as proposed in earlier research, is reviewed and extended further. A client part is created and the implementation is described. The client allows solving the problem of HTTP over DTN usage. An open-source browser is modified and the necessary extensions are developed. The extensions allow to use the DTN transport protocol (i.e. the Bundle Protocol) as another option of transport other than TCP. The software module for a web browser is built on the Mozilla platform. It was shown that it is possible to create a browser to work in DTNs. |
