Aruba EdgeConnect: BOOST in Action!

Aruba EdgeConnect BOOST

In this article, we are going to cover the BOOST feature in Action in our LAB setup. You can see this article extension to another article Aruba SD-WAN: BOOST Feature. The earlier article on BOOST covered the technology overview and here we are going to see the Action.

It’s going to be around the Network Memory component of the Aruba BOOST feature. Which is to save bandwidth consumption using caching, deduplication, and compression techniques. If you have not read the earlier article, please do so to take full advantage of this one.

In any network especially when large files/data need to be accessed by users frequently, we have seen the request comes from the end-users and the same file is served to these users multiple times. I don’t see any harm because this is for a client/server network model built. Servers are to serve clients without complaint.

Let’s think about a scenario where multiple users in a remote branch, need a file [let’s say software patch] from the central server or to be more specific in a large banking setup a circular is released by Head Office and all users in all branches need to read. 

Is it advisable to send the request to fetch data from a centralized update server and get the same file over the WAN? I see some of the issues – premium links are consumed unnecessarily for the same data, and during peak hours it may impact the performance of other critical applications [as it may overutilize the links]. 

What if only the first request is served by a centralized server and all subsequent requests are served locally – this improves the situation manifold. Here we are going to talk about how less traffic is sent over WAN for duplicate data requests. 

Lab Setup

In this simple lab setup, we have two sites connected through MPLS & Internet links. Workstation 1 is the FTP Server and Workstation 2 is the client. We’ll be performing the FTP test between these two workstations to see –

1.       What is the bandwidth consumption & the time to transfer a file without BOOST?

2.       And then the BOOST speeds up the file transfer

Figure 1: LAB Setup

Figure 2 is the output from FTP server (Workstation 1). There is approx. 300 MB of a file (300_MB) that we’ll be transferring from Workstation 1 to Workstation 2. At present, there is no file available on this system. We’ll do the file transfer twice to see how much time it takes to transfer the same file from server to client without BOOST.

Figure 2: FTP Server 300_MB file exists

Figure 3: FTP Client 300_MB file removed & doesn't exist

As per the output below from Workstation 2, file transfer is taking around 54 seconds without BOOST. But when the BOOST feature is enabled, the same file transfer took around 7 seconds.

Figure 4: File Transfer Time

Aruba Orchestrator confirms the level of optimization, using the Flow Tab. It shows approx. 300 MB file over the WAN network is consuming around 5 MB.

Figure 5: Flow Information

This concludes the demo part 1 where we demonstrated BOOST [Network Memory] in action. It not only helps customers to save premium bandwidth for the same data [patch/backup etc.] using the deduplication but also saves time for remote users to get the information. This can be seen as a feature for organizations to increase end-user productivity.

Hope you find this informative. Let’s connect soon for TCP Acceleration another component of BOOST in Action!
