Huawei, a leading global information and communications technology (ICT) solutions provider, showcased a number of SoftCOM solutions at the world's largest SDN forum, the SDN & OpenFlow World Congress 2013. Jointly developed with the world s leading carriers, these solutions mark the beginning of a new phase in the commercial exploration of software-defined networking (SDN) and network functions virtualization (NFV).
SoftCOM is a future-oriented end-to-end ICT network architecture based on technologies and concepts including cloud computing, SDN, NFV, and network openness. It continues to create new value for telecom carriers by helping them tackle challenges and seize market opportunities during ICT integration. As a substantial step toward realizing SoftCOM, Huawei launched the SoftCOM Business Initiatives Zoom-in (BIZ) program which aims to develop strategic partnerships with major carriers. The BIZ program studies each network field to find application scenarios for SoftCOM and develops SDN/NFV solutions that can be quickly deployed on existing networks. It also aims to help carriers benefit from the commercial value of SoftCOM by providing solutions such as SDN-based mobile backhaul, SDN-based Gi service LAN, SDN-based Data Center Interconnection (DCI), Cloud IMS/EPC, virtualized STB, Business Enablement Suite (BES), and Communication as a Service (CaaS). Successfully employed by many carriers, these solutions help them improve network utilization and operation efficiency, reduce structural costs, realize quick customized service provisioning and improve network monetization efficiency.
Huawei's SDN-based Gi service LAN and NFV-based Cloud IMS solutions were among the highlights of the congress. With the rapid development of mobile Internet, the demand for Gi-port bandwidth connecting the mobile network and the Internet has been growing at a fast rate. Adopting a serial structure and static configuration, traditional Gi service LAN only allows for user and business-type traffic data to go through a single service path in a pre-determined order. This will cause two major problems: firstly, expanding the capacity of Gi service units will be costly and will result in huge pressure on capital expenditure (CAPEX); secondly, the service paths cannot be chosen or customized flexibly according to the actual demand. In particular, changing the configuration of the service paths will be extremely complex, and will result in high pressure on operating expense (OPEX) and a negative effect on the efficiency of service delivery.
Based on the SDN concept and technology, Huawei developed a brand new Gi service LAN solution that can support a unified control platform to enable flexible configuration of service paths based on service type, user type and access network type, among other on-demand service paths in different dimensions.
