As such, it is critical to load balance such traffic such that it will not cause network congestion or disruption and affect users\u2019 experience in 6G networks. Motivated by the success of software\u2010defined networking\u2010based load balancing, this paper proposes a novel system called Tigris, to load balance high\u2010volume AAN traffic in 6G networks. Different from existing load balancing solutions in traditional networks, Tigris tackles the fundamental <jats:italic>disruption-resistant challenge<\/jats:italic> in 6G networks for avoiding disruption of continuing flows and the <jats:italic>control-path update challenge<\/jats:italic> for limiting the throughput of updating load balancing instructions. Tigris achieves disruption\u2010free and low\u2010control\u2010path\u2010cost load balancing for AAN traffic by developing an online algorithm to compute disruption\u2010resistant, per\u2010flow load balancing policies and a novel bottom\u2010up algorithm to compile the per\u2010flow policies into a highly compact rule set, which remains disruption\u2010resistant and has a low control\u2010path cost. We use extensive evaluation to demonstrate the efficiency and efficacy of Tigris to achieve zero disruption of continuing AAN flows and an extremely low control\u2010path update overhead, while existing load balancing techniques in traditional networks such as ECMP cause high load variance and disrupt almost 100% continuing AAN flows.<\/jats:p>","DOI":"10.1155\/2021\/9926619","type":"journal-article","created":{"date-parts":[[2021,5,24]],"date-time":"2021-05-24T19:20:06Z","timestamp":1621884006000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Disruption\u2010Free Load Balancing for Aerial Access Network"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8139-2189","authenticated-orcid":false,"given":"Na","family":"Li","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0621-941X","authenticated-orcid":false,"given":"Yue","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8355-0969","authenticated-orcid":false,"given":"Ning","family":"Hu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9438-9683","authenticated-orcid":false,"given":"Jing","family":"Teng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,5,24]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.001.1900318"},{"key":"e_1_2_10_2_2","doi-asserted-by":"crossref","unstructured":"DaoN.-N.
