Tier-1 Internet and Content Provider Chooses

- Design Win Demonstrates the Inherent Synergy in the Silicom Solution

Portfolio: Cloud-Based SD-WAN Solutions Prove Their Value at the Hub Level,

Providing a Comprehensive Networking Solution From the Data Center Through the Edge -

KFAR SAVA, Israel — June 25, 2018, - Silicom Ltd. (NASDAQ: SILC) today announced that a Tier-1 US-based Internet and content provider will be using a version of Silicom’s innovative 200G “Switch-on-a-NIC” card in its distribution hub infrastructure as part of its preparation for an SD-WAN deployment. The card’s combination of advanced hardware and a comprehensive software suite provides a unique unified solution for both the switch and the NIC over DPDK (Data Plane Development Kit).

To date, the Tier-1 customer has placed approximately $1 million in purchase orders for the “Switch-on-a-NIC” adapter.  In parallel, the customer has engaged Silicom in discussions regarding its upcoming edge device needs.

“We are extremely excited to achieve our first Win with this communications giant, a strategic achievement for us on several levels,” commented Shaike Orbach, Silicom’s CEO. “The fact that our Cloud Switch on a NIC solution has now been adopted for use in a hub architecture upgraded for SD-WAN is great news for us. It allows us to capitalize on the relationships that we have built through our sales of SD-WAN edge devices, proposing solutions that will allow us to penetrate more deeply into our customers’ infrastructure.

“In parallel, this solution enables us to approach additional service providers looking for an SD-WAN hub infrastructure solution, and from there to propose solutions for their edge requirements. As such, we believe that this win will allow us to further increase our market share of the uCPE Edge segment as well as the hub and central infrastructure markets, including Data Center and Cloud segments.

Mr. Orbach concluded, “The fact that this customer came to us demonstrates how deeply we have become integrated into the SD-WAN space and just how powerful our technology and solution approach are. The Win confirms that both our central infrastructure and edge solutions are essential building blocks for SD-WAN, NFV, Cloud and Data Center infrastructures, positioning us even more favorably to ride the growth of the SD-WAN, Cloud and Data Center spaces.”
