The need for new transport protocols on the INTERNET

Abstrakt

The TCP/IP protocol suite is widely used in IP networks, regardless of diverse environments and usage scenarios. Due to the fact of being the basic concept of organizing the work of the Internet, it is the subject of interest and constant analysis of operators, users, network researchers, and designers. The Internet is a "living" organism in which new needs appear all the time. This is particularly important due to the emerging new application requirements - at the highest level of network architecture, and at the same time, completely new ways of transmitting messages related to new technologies and reception techniques, allowing for parallelization of messages transfer and lossless switching/handover between several interfaces. The paper highlights the expectations and requirements related, in particular, to new "multi-object" applications, as well as the limitations resulting from the high inertia observed on the side of the IP network transport infrastructure. Taking into account both the limitations and the formulated requirements, the selected end-to-end transport protocols have been characterized. More attention was paid to two protocols implementing multi-stream transfers, namely SCTP and QUIC.
