In the past year i was working on a graphical interface for Netfloc – the SDK for SDN developed in the SDN initiative. Just to remind you, the aim of Netflogi is to: (1) make the SDK itself easy to use and (2) expose the Netfloc APIs and functional features to the network application developers and datacenter service providers.
With the initial version of Netflogi, the user was able to create a Service Function Chain only by using Neutron port IDs. This was done by choosing the number and the order of the Neutron ports used in the Chain. The current version of Netflogi allows to create Virtual Network Functions (VNFs) and a Service Chain using those VNFs. This blog post describes the updated functionalities of Netflogi that take part of the development work i did as part of my final exam, called IPA in Switzerland.
The novel functionality added in Netflogi is the VNF management (create & delete). Creating VNF includes choosing a name, a description of the functionality and assigning ingress and egress ports. Once the VNF is successfully created, it appears automatically in the list of the existing VNFs. The VNFs can be used in different services offered by Netfloc. Currently Service Function Chaining is fully implemented and can be done by combining one or more VNFs. The VNFs can be deleted, as well as the Service Chains. Help page and messaging system for the performed actions is also included in this version.
