This solution falls within the technology:

Distributed Network Functions – uCPE

In connection with SDN there are discussions about applications that are offered by this open network architecture. There is a new application interface that offers access to applications without regional boundaries while network functions are virtualized. The term Network Functions Virtualization (NFV) is often mentioned in this context – it means functions that are in fact independent of SDN, while NFV can utilize the open nature of the SDN interface to the maximum. We need to deliver applications (network functions) to the customer dynamically, based on customer’s current needs. Majority of such virtualized functions will remain in the data center, being allocated to customers dynamically. But there are also functions that we would wish to virtualize, and these must be implemented at the customer. We need an open platform for terminal devices that would allow us to allocate network functions dynamically as needed, thus we need distributed NFV.

uCPE is an open-architecture demarcation device for the installation of VNF instances, based on x86 architecture. The device thus allows us to install new virtualized functions. Whether it is a firewall, VPN, SD-WAN, router etc. From both the operator’s and customer’s perspective, it combines the function of service delivery by the operator to the customer under the guaranteed SLA, variability of network functions and VNF distribution from the central network location. The customer may choose network functions and applications as necessary, with the option to install them as deemed appropriate.

Solution advantages:

  • Short deployment time
  • Scalability
  • Lower costs
  • Resource optimization
  • Open offer of network functions and applications

Distributed Network Functions – uCPE

The solution diagram describes interconnection of two sites and a private or hybrid data center (DC), where the main technology is located, comprising of an Orchestrator, the Management System and a repository of virtual instances (VNF). On the remote site there is uCPE device based on x86 architecture, running the applicable VNF instance for the required functions.

For illustration we can create a VPN interconnection between two sites. To implement such a VPN link, we need to install VPN VNF at the data center and at uCPE at the remote location. Thus, we can create a secure connection between two sites with data encryption and decryption abilities
