Likely the best place go receive most correct answers is to pose each of your questions to each vendor.

From a high level, velocloud can be run as either a bare metal traditional router or a virtual appliance on ESXi or KVM. The VEP4600 is simply an x86 appliance running ESXi from dell that is geared toward NFV, far from the only hardware that can run velocloud.

Hi Aaron;<br />
Thanks for responding to my Q on Velocloud, I want to know more about how to run it an instance as Virtual router to the branch site? Do we just provide an Internet access to the branch and all other functions are happening in the cloud? Can you Please explain the VNF functionality.
</div>


<div>
It runs just like any other virtual router, give it LAN and WAN interfaces and route through it. Physically It wires up just like any edge router: sonicwall, fortinet, Palo Alto, etc. &nbsp;if this is your first run at it, probably best to start with a physical appliance in a lab to get comfortable with the technology.
</div>


<div>
Is this virtual router feature available on NSX Velocloud by VMWare or all the other SDWAN provides (Cisco Viptela/Nokia Nuage) provide it?
</div>


<div>
Most sdwan offerings have a virtual appliance version. For example, velocloud and viptela have a version for AWS and Azure. Running on x86 hardware is a direction all the SDN is going.

<div>
Thanks Aaron, I am beginning to see the light.. so if the customer has bunch of Cisco branch routers already deployed in the field, can we run Velocloud in conjunction w/ the customers' existing investment in Cisco gear?
</div>


<div>
Yes, Velocloud and Cisco routers can absolutely coexist in a network. Any decent sized network is going to have gear from multiple manufacturers. I frequently see velocloud, Cisco, and Palo Alto all working together to meet the network and security requirements.
</div>


<div>
Are both uCPE and VEP Controller based on the same H/W base that is x86 servers?
</div>


<div>
UCPE is short for universal customer premise equipment and can mean anything but is usually a KVM or ESXi hypervisor on x86 hardware. Frequently they are kitted out with lots of front network ports and look like a firewall but are not really that different from any other hypervisor host. The VEP is new and not proven In the field but probably a good platform. Most existing gear in the market today is based on lanner or super micro and significantly less powerful than the VEP as far as cores and ram. For just sdwan, the VEP is a overkill but for also running a few server VMs at the edge it would be a good fit.

Aaron,<br />
Seems to me , you have very good grasp over the SDWAN Topic. We have the customer who is running existing MPLS Network and we want to supplement their branches/sites w/ uCPE devices so that additional traffic is passed over SDWAN to rest of the sites This is the scheme we are proposing where MPLS Network works in conjunction w/ SDWAN. &nbsp;MPLS traffic would ride over private link (Primary) and we will get internet to connect uCPEs to carry any aditional traffic to save on expensive MPLS.<br />
&nbsp;<br />
I have the following doubbts in this scenario:<br />
1. Is it feasible to run MPLS connected nodes w/ SDWAN Cloud?<br />
2. How would orchrestation layer device take control of MPLS Router, if want to control the traffic on its private Eth. link? To me, it is appearing that we are operating two different clouds. Can yiou please shine some light.<br />
<br />
<br />
Thanks in advance.

Hi Experts;<br />
We are asked by our customer to look into VMWare Velocloud Deployment for SDWAN, can you please shine some light on:<br />
1. Does it always need to have uCPE as the branch routers or can it work w/ Cisco routers?<br />
2. Can we get some 95% Percentile traffic statistics from VEP4600 controller ?<br />
3. Any other point that you point that you might want to highlight esp. about NFV..<br />
<br />
Some documentation would be highly appreciated.<br />
<br />
Thanks;

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Cloud services are services made available to users via the Internet from a provider's servers. Cloud services are designed to provide easy, scalable access to applications, resources and services, and are fully managed by a cloud services provider. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources. Frequently offered cloud services are infrastructure-as-a-service (IaaS), desktops-as-a-service (DaaS), software-as-a-service (SaaS) and platform-as-a-service (PaaS). Examples of cloud services include online data storage and backup solutions, Web-based e-mail services, hosted office suites and document collaboration services, database processing, managed technical support services and more.
