NTT, Cisco Systems, Juniper Networks, and Hewlett-Packard Japan are testing service chaining based on network functions virtualisation (NFV) principles. The use case has been approved as an authorized PoC (Proof of Concept) by ETSI's Industry Specification Group for Network Functions Virtualisation (NFV ISG). This is the first such trial use case in Japan (the second in the world) approved as a PoC.
NTT said interoperability will be crucial for its vision of service chaining, in which virtualized appliances are interconnected in conjunction with networks.
For this PoC, multiple multiple services from multiple vendors are chained together. NTT Network Technology Laboratories is developing a service chaining method in which each packet is assigned an identifier to enable customers to select and apply virtualized functions on demand. The identifier shows a chain of virtualized network functions and forwards packets to them as appropriate.
NTT: Providing service chaining method
Cisco Systems: Providing vDPI
Juniper Networks: Providing vFW
Hewlett-Packard Japan: Providing vCPE
A demonstration is being held this week at the NTT R&D Forum 2014.
