IEEE LANMAN has an established tradition as a forum for presenting and discussing the latest technical advances in local and metropolitan area networking. Continuing that tradition, IEEE LANMAN 2025 invites cutting-edge papers spanning both theory and experimentation. The organizing committee is delighted to invite you to the 31st IEEE LANMAN (LANMAN 2025) to be held from July 7 to 8, 2025. IEEE LANMAN 2025 solicits paper submissions of papers up to 6 pages.
