3 Signalling aspects

Introduction

Network services offered by carriers are far from adequate for the ever-changing requirements of Internet
applications. As the key position to offer broadband network services, the broadband network gateway
(BNG) should be able to support flexible service combination, new services introduction and provisioning.
Carriers can then greatly improve their network service capability, bandwidth utilization and end user
experience. Thus, the BNG will achieve the following outstanding benefits:
• easy deployment of network services, easing the strain of network updates;
• fine-grained network service handling and bandwidth utilization;
• greatly improved end user experience, based on the network services oriented to newly emerging
network application techniques.
The service platform-BNG architecture is suitable for the feature requirements. The service platform is in
charge of the BNG. Network services deploy on the service platform. The BNG acts according to the service
platform's control information. The following three aspects are required for the features:
1) network services combination/orchestration, i.e., the packet routes between network services;
2) service configuration to the BNG;
3) BNG resources, status and event notification to the service platform.
