ZTE ElasticNet 2020 Solution

ZTE’s ElasticNet 2020 provides an innovative architecture and total solution to support digital transformation by restructuring service and operation to extend and improve the existing network.

ElasticNet 2020 focuses on Triple-layer Re-architecture: restructure the networks using cloud computing and the fact that SDN/NFV can be illustrated in three layers:

  • Infrastructure Re-architecture: To build up a cloud–and-network converged infrastructure layer that is defined as ‘Elastic Cloud Infrastructure’

  • Network service Re-architecture: To construct a virtualized and open service function layer that is defined as ‘Elastic Cloud ServiceTM

  • Operation Re-architecture: To compose a smartly-operated orchestration layer that is defined as ‘MICT-OSTM

Empowered by the technologies of cloud computing, big data and SDN/NFV, ElasticNetTM involves software-defined networks featuring a layered structure, centralised control and unified management. The ElasticNet architecture and solutions have been deploying in three typical scenarios to accelerate the network evolution.

CO Re-construction

  • Reconstructing the large number of existing central offices and legacy equipment
  • Utilizing these physical resources for ‘telecom cloud’
  • Transforming legacy networks into SDN and NFV-based networks

ZTE’s CO re-construction solution provides an approach to transforming existing architecture from metro access networks (MANs) to networks based on edge-DCs. The control plane will be separated from the forwarding plane and the functions such as BNG, CPE and OLT will be virtualized and centrally deployed on edge-DCs, and further, the vCDN and vEPC-U will be migrated down to the edge-DCs. High-performance commodity devices will be used as the forwarding plane devices and formed to resource pool so that they are able to meet future requirement for ultra-bandwidth processing. Concurrently, by resource sharing, they are able to reduce the quantity of devices and consequently produce savings in CapEx and OpEx.

Cloud-native based Network Slicing

With the impending arrival of 5G, mobile broadband systems will be full service networks that integrate multiple technologies to meet various application needs. 5G-oriented network slicing is a mechanism that can be used by operators to support network functions running parallel on the same chipproviding on-demand slicing capabilities.

 

By introducing NFV enhanced ICT PaaS Cloud WorksTM, ZTE’s ElasticNetTM constructs cloud services by intelligent VNF management and agile DevOps process. This cloud service platform will attract more developers to promote the innovation of personalized and diversified services.

Network on-Demand

To break through the limits of users’ access to the network resources, ZTE network on-demand solution provides essential applications for network capability exposure. With it, the customer will be able to acquire a range of on-demand services. These DIY services include:

  • Flexible and instant network connection services
  • Options on bandwidths, site locations and QoS levels
  • Customized end-to-end reliable automated leased line services
  • Order of service functions, including NAT, firewalls and DPI
