Outline l Introduction l Previous Works l Proposed Openwincon Architecture l Conclusion National Cheng Kung University CSIE Computer & Internet Architecture Lab 2

Introduction l Software Defined Networking / Network Function Virtualization (SDN/NFV) is considered as a key technology for future mobile networks National Cheng Kung University CSIE Computer & Internet Architecture Lab 3

Previous Works l The conventional heterogeneous network architecture is depicted in Figure 1. National Cheng Kung University CSIE Computer & Internet Architecture Lab 4

Previous Works LTE 3 G Internet National Cheng Kung University CSIE Computer & Internet Architecture Lab 5

Previous Works l l l The network complexity is increased in terms of network manageability and controllability. SDN/NFV provides a solution for this type of environment. A difference between networks can be implemented as a single physical device with virtualized applications. National Cheng Kung University CSIE Computer & Internet Architecture Lab 6

Proposed Openwincon Architecture l l The mobile network architecture based on openwincon is depicted in Figure 2. Support conventional wired and wireless networks and future networks such as 5 G. National Cheng Kung University CSIE Computer & Internet Architecture Lab 7

Proposed Openwincon Architecture l Five major features are considered. First, the Access Abstraction Manager (AAM) terminates air link dependent functionalities to abstract the multiple networks. National Cheng Kung University CSIE Computer & Internet Architecture Lab 10

Proposed Openwincon Architecture l The Radio Resource Manager (RRM) manages wireless resources such as frequency, bandwidth, and interference. Also, wireless scheduling is enabled to guarantee the Qo. S/Qo. E of services. National Cheng Kung University CSIE Computer & Internet Architecture Lab 11

Proposed Openwincon Architecture l l The Network Resource Manager (NRM) manages wireless resources. NRM includes Open. Flow-based network control. National Cheng Kung University CSIE Computer & Internet Architecture Lab 12

Proposed Openwincon Architecture l l The Access Control Manager (ACM) provides managements for subscribers, devices, and services. ACM includes control and management of authentication, authorization, accounting, security, and service policy National Cheng Kung University CSIE Computer & Internet Architecture Lab 13

Proposed Openwincon Architecture l l The Mobility Manager (MM) provides mobility control for subscribers and devices. MM provides seamless and consistent handover scheme over heterogeneous wireless network environments. National Cheng Kung University CSIE Computer & Internet Architecture Lab 14

Proposed Openwincon Architecture l We support carrier-grade reliability initially. As depicted in Figure 3, each controller supports reliability via a distributed multicore architecture. National Cheng Kung University CSIE Computer & Internet Architecture Lab 15

Proposed Openwincon Architecture l l Each manager operates over multiple distributed cores. It avoids service destruction when a single core fails. Also, inter-controller reliability is guaranteed through multi-site redundancy. Thus, a controller level failure is recovered via a peering controller.
