ETSI has launched the OSM Project ( https://osm.etsi.org/ ) to take the focus of innovation away from Management and Orchestration and keep it on the VNFs. The VNFs are the building blocks of network services and as such they are glued together to provide communication services.
Much of the work and innovation will be on efficient VNF internal design and efficient Network Services design. The Network Services design is a network designe or network architects duty while good and efficient VNF’s are provided by software engineers.
All in all two base skills appear to be handy. One is Linux as base technology for managing infrastructure, providing hypervisor functionality, as base OS within VNFs and also as base OS for VNFM’s as well. Second will be good Network Service design where with increasing amount of VNFs becoming available piecing them together to provide communication services given the constraints put by the system will be a skill.
OPNFV is a platform. It is an integrated system of components that individually make up streams of projects which when combined together provide a platform upon which VNFs can be run. http://openbaton.github.io/ is a practical implementation for an open source NFVO. If one can get a vMME, vSGW, vPGW and vHSS (together being a vEPC) working together then the product is an NFV Lab.
Some of the attempts can be listed as:
I gave and cleared the Brocade Certified vRouter (Vyatta) Engineer Exam on 19th June.
Here’s a copy of my certificate:
Brocade Certified vRouter Engineer 2013 certificate
The Vyatta router practice sessions on the VMware Player helped a lot in addition to the SDN Trainings and the Nutshell guide provided by Brocade.
I decided to setup a simple firewall on my Vyatta VM router to block pings from another VM Host (Ubuntu 12.04). The network is entirely in the range 192.168.0.100/24. The Ubuntu Host IP is 192.168. 192.168.0.111
The Vyatta interface IP is 192.168.0.108
Ping between them is working prior to setting up firewall and gives destination port unreachable as soon as firewall is enabled via commit.
The firewall configuration is as below:
The configuration steps are simple and given below:
and then we need to apply the firewall to an interface which in this case is eth0.
After the above configurations are in place enter commit to apply them and ping will stop working.
We can also see the statistics in firewall section changing:
and also by name the firewall:
and also show firewall name *** statistics :
In my setup to set up DNS forwarding in the Vyatta router two steps needed to be followed. The first being configure an interface as a listen on interface. I configured this to be eth0 which is bridged to my Wifi rotuer. The second step is to configure a name server. I set this as the default gateway of the network i.e. the Address of the Wifi router.
Once done I was able to ping google from my vyatta VM.
There’s a number of steps that need to be done to set up your own mini lab of the Brocade Vyatta router. Firstly instead of re-inventing the wheel on my blog please follow all instructions given on the below blog post:
Instead of uploading to Datastore and using vcenter you can use the free VMplayer that VMWare offers.
After completing the installation steps you should be able to SSH into the vyatta VM and also make configuration changes. One additional step I would recommend is to hit the command save after running commit at the end of instruction set.
Listening to Ivan Peplnjack’s webinar on NFV gave good insight into this new term from the ETSI. The initiation of NFV is coming from the ETSI which brought us GSM and 3GPP as well. Using virtualisation to move the networks functionality from dedicated appliances to generic x86 hardware brings much needed flexibility in network design from service provider perspective. This should then result in reduction of time to market for new apps and services.
