1. Application Policy on Network Functions (APONF) G. Karagiannis and T.Tsou 1

2. APONF Problem Description (1)  Cloud applications, cloud tenants and developers usually need to use communication network capabilities, e.g., dynamic network management, easily, accurately and efficiently  deployment of new applications and services may be accelerated and user experience can be improved  Network operators are challenged to create an abstract view of network infrastructure and help service developers on using and programming this abstraction 2

3. APONF Problem Description (2) Challenges (1)  Abstract view of a network infrastructure need to be realized using e.g., a network service graph that includes network service attributes, e.g.,:  Service dependencies, network configuration and topology  Application based policies  For each network management application (OSS application like) instance an unique network service graph needs to be generated and maintained 3

4. APONF Problem Description (3) Challenges (2)  Up to date (fresh) network service graph needs to be communicated between network management application systems and network management and controlling systems 4

5. APONF Problem Description (4) Challenges (3)  Attributes, including application based policies, of network service graph need to be mapped into specific network management policies 5

6. APONF Goal  APONF can provide solutions to these challenges by:  Model network service graph, which among others include application based policies, using Yang  Use Netconf to enable the dissemination of up to date (fresh) network service graphs in a secure and efficient manner between network management application systems and network management and controlling systems  Guidelines on mapping attributes of network service graphs provided by network management application systems into specific network management policies 6

8. APONF Work Items specify network service graph based on Yang models that represents abstract view of network infrastructure specify how Netconf/Yang can be used to securely and efficiently distribute up to date (fresh) network service graphs between network management applications and network management systems, the routing controlling system or other controlling systems specify mechanisms that can dynamically map attributes, including application based policies, of network service graphs into specific network management policies document how to use Netconf authentication and authorization mechanisms to achieve protection and isolation 8

9. APONF Non Work Items specification of the network management policies and their associated device configuration models 9
