The IETF recently specified a PMTU discovery framework for transport protocols like QUIC. This paper complements this specification by presenting a search algorithm. In addition, it defines several metrics and shows results of analyses for the algorithm with various PMTU candidate sequences using these metrics. We integrated the PMTU discovery with our algorithm into a QUIC simulation model. This paper describes the integration and presents measurements obtained by simulations.}, language = {en} } @inproceedings{VoelkerVolodinaTuexenetal.2020, author = {V{\"o}lker, Timo and Volodina, Ekaterina and T{\"u}xen, Michael and Rathgeb, Erwin Paul}, title = {A QUIC Simulation Model for INET and its Application to the Acknowledgment Ratio Issue}, series = {2020 IFIP Networking Conference}, booktitle = {2020 IFIP Networking Conference}, publisher = {IEEE}, address = {New York, NY, USA}, isbn = {978-3-903176-28-7}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:836-opus-149662}, pages = {737 -- 742}, year = {2020}, abstract = {Quick UDP Internet Connections (QUIC) is a novel transport protocol introducing known features in a new protocol design. To investigate these features and the design, we developed a QUIC implementation in the INET simulation model suite. In this paper, we describe that implementation, its validation and a result achieved using the simulation model. The result shows the negative impact on throughput, when raising the acknowledgment ratio. We propose a solution and describe how it solves the issue.}, language = {en} }
