The crossconnect switches can be implemented as wavelength routers resulting in WDM networks, or as ATM Virtual Path (VP) switches leading to ATM compatible network systems. We show in the paper that this network architecture results in a significant increase in throughput performance in comparison with (SDHISONET) ring networks. For a certain class of meshed rings, under a uniform traffic matrix, we derive the optimal topology which achieves maximum throughput efficiency. Using such a topology, we obtain upper and lower bounds on the number of wavelengths required to achieve that efficiency level. The network is divided into (overlapping) communities of nodes. Each community is assigned a wavelength and a subnetwork (identified as a wavelength graph). Each pair of nodes in a community can communicate across the associated wavelength graph. Wavelength graphs (subnets) are constructed to demonstrate the implementation of the routing scheme using the number of wavelengths that is equal to the derived upper bound. For practical implementation reasons, we investigate the performance of networks which employ a reduced number of wavelengths. We show that by modifying the topological layout of the meshed ring network, we can reduce substantially the number of required wavelengths, while incurring just a modest reduction in throughput efficiency.<\/jats:p>","DOI":"10.1002\/ett.4460110111","type":"journal-article","created":{"date-parts":[[2008,9,12]],"date-time":"2008-09-12T14:56:52Z","timestamp":1221231412000},"page":"83-90","source":"Crossref","is-referenced-by-count":2,"title":["All\u2010Optical WDM Cross\u2010Connect Meshed\u2010Ring Communications Networks"],"prefix":"10.1002","volume":"11","author":[{"given":"Izhak","family":"Rubin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Ling","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,9,12]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"878","article-title":"A review of the four major SONETlSDH rings","volume":"2","author":"Drake J.","year":"1993","journal-title":"ICC'93"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0169-7552(94)90047-7"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0169-7552(94)90045-0"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/26.212370"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/INFCOM.1995.515972"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/GLOCOM.1995.502709"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1093\/comjnl\/38.1.71"},{"key":"e_1_2_1_9_2","first-page":"310","article-title":"Symmetric degreefour chordal ring networks","volume":"137","author":"Browne R.
