This document suite describes the EML-NML (Element Management Layer-Network Management Layer) for the management of IP VPN and Voice over IP (VoIP) related services. The networking industry today is experiencing explosive growth of IP (Internet Protocol) networks and services; drivers for this revolution include the following: - Growing bandwidth demand from businesses and residential users needing to interconnect at higher and higher bandwidth rates over time due to new and emerging bandwidth-intensive applications (digital imaging, streaming audio & video, Internet Telephony, video conferencing, etc.) - Convergence of many disparate networks into an integrated voice, video and data infrastructure for cost efficiency (among other reasons) - Flexibility provided by IP to address diverse applications and services - Relative ubiquity of IP devices and networks
New services based on IP typically ride on an increasingly complex IP network infrastructure. Integrated IP network management architecture and systems are a necessity to effectively address the broad range of new and emerging IP networks and services.
TMF514 EML-NML Requirements for Management of IP Networks and Services Business Agreement defines the business problem and requirement model for EML-NML management of IP networks and services. The Business Agreement is used to gain consensus on the business requirements for exchanging information among processes and systems in order to solve a specific business problem.
TMF611 IPNM EML to NML Interface Agreement is limited to the definition of the protocol neutral interface information model and class models of the NML-EML interface for management of IP networks. The set of interface information requirements statements and interface information use cases are defined in TM Forum IP Network Management Business Agreement, NML-EML Interface (TMF 514).
