The simultaneous use of these multiple interfaces for a communication session would improve user experience through higher throughput and improved resilience to network failures. <\/p>\n\n<p align=\"justify\">MPT is a network layer multipath solution, developed by our research group, which provides a tunnel over multiple paths using the GRE-in-UDP specification, thus being different from both MPTCP and Huawei&#8217;s GRE Tunnel Bonding Protocol.<\/p>\n\n<p align=\"justify\">MPT can also be used as a router, routing the packets among several networks between the tunnel endpoints, thus establishing a multipath site-to-site connection.<\/p>\n\n<p align=\"justify\">The version of tunnel IP and the version of path IP are independent from each other, therefore MPT can also be used for IPv6 transition purposes.<\/p>\n\n<strong>Current developers:<\/strong><br><br>\n\nDr. Szil\u00e1gyi, Szabolcs &#8211; project officer<br>\n<br>\n\n<strong>Earlier team members:<\/strong><br><br>\n\n&#8224;Dr. Alm\u00e1si, B\u00e9la &#8211; earlier project officer<br>\nDr. K\u00f3sa, M\u00e1rk &#8211; IT teacher<br>\nKelemen, Tam\u00e1s &#8211; BSc student<br>\nFejes, Ferenc &#8211; MSc student<br>\nKatona, R\u00f3bert &#8211; MSc student<br>\nP\u00fcs\u00f6k, Levente &#8211; BSc student<br>\nHarangi, Lajos &#8211; BSc student<br>\nKiss, Benj\u00e1min &#8211; BSc student<br>\nBord\u00e1n, Imre &#8211; MSc student<br>\n<br>\n\n<strong>MPT resources:<\/strong><br><br>\n\n<ul>\n<li>MPT-GRE Internet Draft [<a href=\"https:\/\/tools.ietf.org\/html\/draft-lencse-tsvwg-mpt-09\">link<\/a>]<\/li>\n\n<li>Downloadable MPT-GRE package  [<a href=\"https:\/\/github.com\/spyff\/mpt\/\">download<\/a>]<\/li>\n\n<li>MPT-GRE user manual (English) [<a href=\"\/~szilagyi\/wp-content\/uploads\/mpt\/usermanual.pdf\">download<\/a>]<\/li>\n\n<!-- <li>Downloadable MPT-GRE package (PC, Linux, 32 bit) [<a href=\"\/~szilagyi\/wp-content\/uploads\/mpt\/mpt-gre-lib32-2016-06-16.tar.gz\">download<\/a>]<\/li>\n\n<li>Downloadable MPT-GRE package (PC, Linux, 64 bit) [<a href=\"\/~szilagyi\/wp-content\/uploads\/mpt\/mpt-gre-lib64-2016-06-16.tar.gz\">download<\/a>]<\/li>\n\n<li>Downloadable MPT-GRE package (Raspberry, Raspbian) [<a href=\"\/~szilagyi\/wp-content\/uploads\/mpt\/mpt-gre-rpi-2016-06-16.tar.gz\">download<\/a>]<\/li> -->\n<\/ul>\n\n<strong>MPT papers:<\/strong><br><br>\n\n<strong>2025.<\/strong><br><br>\n\n<ol><li><p align=\"justify\"><strong>Szabolcs Szil\u00e1gyi<\/strong>,  <em>Weighted Scheduling in Multipath GRE-in-UDP: Mathematical Modeling and Experimental Analysis<\/em>, Proceedings of the 18th International Conference on Engineering of Modern Electric Systems (EMES 2025), IEEE, pp. 1-4, DOI: 10.1109\/EMES65692.2025.11045626, Oradea, Romania, May 29-30, 2025.
