How do we reduce the cost of maintaining the network by more than 60 percent?

More than you expect. Exactly as much as you need.

In Salumanus's work philosophy, conversations with clients are key. Together, we study the needs and look for the best solutions for a given network infrastructure. Often the final result differs from the guidelines that we received at the very beginning. Always for the benefit of the customer's business.

Today we will tell you about cooperation with a large insurance company. They received from Salumanus a solution that reduces the monthly cost of maintaining the connection network by up to 63 percent. At the same time, increasing the network bitrate by almost 10 times! In addition, we have proposed a more advantageous method of encrypting the transmission.

How did we do it? Read in our use study:

Customer Profile: A leading company in the financial and insurance sector. Present in dozens of countries, with millions of customers around the world.

Customer need: The request for a quote related to the migration of the 10GbE to 40GbE connection network. The customer planned to encrypt these transmissions at Layer 2. He also needed to increase the SAN bitrate from 16G to 32G, then encrypt it. The vendor of the switches they owned was unable to secure the 32G Fibre Channel transmission. So they turned to Salumanus for help.

What did we propose?

As always, we started with a conversation with the customer. We have collected a complete set of information about the parameters of the links and analyzed the needs. When designing the solution, we took into account safety issues, the amount of capital expenditure (CAPEX) and the possibility of making significant savings in system maintenance (OPEX).

The solution we proposed allowed to encrypt 100G traffic (2.5 times more than the customer expected), and transfer traffic 32 Fibre Channel.

In the client's assumptions, there were two optical paths: the primary path (5 pairs of fibers) and the backup path (6 pairs of fibers). In our solution, instead of using 11 pairs of optical fibers, we used only 4 pairs of fibers: the primary path (2 pairs of fibers) and the backup path (2 pairs of fibers)

The rental of each additional pair of fibers affects the cost of maintaining the system. Giving up seven couples means Savings of 63 percent. This is a significant difference in the cost of monthly maintenance of this piece of the network.

There remains a second element of assumptions. The client's guidelines called for Layer 2 encryption. We proposed Layer 1 encryption. Why? By encrypting the data in layer one, we block the reading of data from the frame headers, therefore also information about who is the sender and who is the receiver (which we cannot do in L2 or L3 encryption). This increases the security of the transmission.

Another advantage of layer 1 encryption is the fact that no matter what size frames we have, whether smaller or larger, we will always keep 100 percent link performance.

How did we do it?

We installed Muxpondery PL-2000ADS PacketLight Networks. It is a compact 1U solution that allows you to encrypt and transport services such as 10Gb/40Gb/100Gb Ethernet and 8G/16G/32G Fibre Channel. Thanks to this, on the linear side we can use QSFP28 100G (OTU4) modules. And this means that muksponders will work both for encrypting movement based on dark fibers, and as a lambda alien. Importantly, they are completely transparent to LAN/WAN or SAN devices and allow you to encrypt all or a selected part of the traffic in the first layer.

The solution proposed by Salumanus engineers is flexible and secure. The launch of the next service within the already existing 100G transmission (OTU4) is possible at any time. We also have the freedom to choose the services we need. No need to put together a new optical path.

The second important value is safety. We can encrypt each service independently with a certified service GCM-AES-25. All this is done on the transmission layer (L1), which means that the entire solution is completely transparent to switches (L2) or routers (L3).

What does the client gain?

Cheaper to maintain, secure network that can be easily expanded. We achieved this effect thanks to mutual trust and openness to non-standard solutions. And although the end result was different from the original assumptions of the client, the goal was achieved. Thanks to muxponders We reduced network maintenance costs by about 63 percent and encrypted the transmission in Layer 1, protecting both sender and receiver data.
