Multipath RMSA offers a number of benefits including provisioning of ultra-high bandwidth demands and better utilization of fragmented spectrum resource. By Combining with traffic grooming, multipath RMSA and traffic grooming is able to provide better utilization of network resource in provisioning connection requests. Adding multi-hop routing mechanism to multipath RMSA and traffic grooming increases the flexibility for selecting paths resulting in higher probability of successfully finding routing paths for connection requests. Dynamic multipath RMSA problem in EON has been investigated extensively in the literature. Dynamic multi-hop multipath RMSA and traffic grooming problem in EON is far from been well studied. This paper proposes an algorithm for the dynamic multi-hop multipath RMSA and traffic grooming problem in OFDM-based elastic optical networks with sliceable bandwidth-variable transponders. Performance of the proposed algorithm is studied via simulation. Our simulation results show that the proposed algorithm yields lower bandwidth blocking ratio than an existing algorithm.<\/jats:p>","DOI":"10.3233\/jhs-222007","type":"journal-article","created":{"date-parts":[[2023,3,31]],"date-time":"2023-03-31T11:56:41Z","timestamp":1680263801000},"page":"85-103","source":"Crossref","is-referenced-by-count":2,"title":["Dynamic multi-hop multipath RMSA and traffic grooming in OFDM-based sliceable elastic optical networks"],"prefix":"10.1177","volume":"29","author":[{"given":"Hwa-Chun","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Computer Science, National Tsing Hua University, No. 101, Section\u00a02, Kuang-Fu Road, Hsinchu, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei-Te","family":"Tseng","sequence":"additional","affiliation":[{"name":"Institute of Communications Engineering, National Tsing Hua University, No. 101, Section\u00a02, Kuang-Fu Road, Hsinchu, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/JHS-222007_ref1","doi-asserted-by":"publisher","first-page":"5","DOI":"10.1016\/j.osn.2016.08.003","article-title":"Study and analysis of routing and spectrum allocation (RSA) and routing, modulation and spectrum allocation (RMSA) algorithms in elastic optical networks (EONs)","volume":"23","author":"Abkenar","year":"2017","journal-title":"Opt.
