FREMONT, CA: AT&T, Palo Alto Networks, and Broadcom have joined hands to develop a disaggregated scalable firewall (DSFW) framework to split network elements into smaller pieces. The DSFW is an expansion of the distributed disaggregated chassis (DDC) that AT&T contributed to the Open Compute Project (OCP) last September. Being one of the primary industry drivers, AT&T has pushed the design and implementation of lower-cost white box switches and router.

DSFW added with DDC will enable a dynamic programmable fabric with embedded security functions and services at the network edge. DSFW will also grant means for future scalable disaggregated applications services. Palo Alto Networks and AT&T said they look forward to OCP's input on DSFW.

Palo Alto Networks is working to provide network security at the edge that allows protection of the network continuously with automation and analytics. To deal with the rising network traffics during peak time periods, Palo Alto is helping DSFW to scale up is operation dynamically.

"Security has always been at the forefront of AT&T's network initiatives," said AT&T's Michael Satterlee, vice president, Network Infrastructure and services, in a statement. "Traditionally, we have had to rely on centralized security platforms or co-located appliances that are either not directly in the path of the network or are not cost-effective to meet the scaling requirements of a carrier.”

"We now carry more than 335 petabytes of data traffic on our global network on an average day, with 5G poised to push that number even higher. Securing that cargo using traditional methods just won't work. This new design embeds security on the fabric of our network edge that allows control, visibility, and advanced threat protection."

The open hardware and software of DSFW support flexible deployment models. It is focusing on the use of machine learning and AI to prevent attacks as the actionable events that are embedded in the network fabric does not require separate hardware.

The OCP Global Summit conference, scheduled this week, was canceled due to concerns over the coronavirus. OCP will instead host an interactive Virtual Global Summit during the week starting May 11.
