In order to address those challenges, the 5G system design demands new architectures to cope with specific requirements, such as scalability, resilience, and energy efficiency. These requirements play a fundamental role in extremely dense scenarios. In addition, when jointly addressed, they have distinct priorities depending mainly on the specific user application demands. In this context, this article presents a management architecture for 5G system, called Wireless Software-basEd architecture for Extremely Dense networks (WiSEED). It is grounded on a software-based perspective of management and jointly manages three key operational services, as follows: routing, mobility, and spectrum usage. Such perspective of management is possible due to programmable network technologies, i.e., network function virtualization and software-defined networking. The architecture mainly intends to provide a better trade-off between the 5G requirements themselves and a high quality ubiquitous and seamless services, as well as efficient mobile broadband Internet for end users. Trace-driven simulation results from a case study show improvements when the management architecture is employed over conflicting requirements.<\/jats:p>","DOI":"10.1186\/s13638-015-0380-8","type":"journal-article","created":{"date-parts":[[2015,6,10]],"date-time":"2015-06-10T15:57:15Z","timestamp":1433951835000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Aspirations, challenges, and open issues for software-based 5G networks in extremely dense and heterogeneous scenarios"],"prefix":"10.1186","volume":"2015","author":[{"given":"Vinicius C.","family":"M.
