AT&T is making significant progress with its open, disaggregated program. In a blog post, Mike Satterlee, vice president, Network Core Infrastructure Services, cites the following milestones:
- More than 52% of all production traffic are delivered over Next-Gen Core routers, which are based on the Broadcom Jericho2, Ramon chips and which use the Distributed Dis-Aggregated Chassis (DDC) design powered by DriveNets Network Cloud DNOS software. AT&T is exploring a path to scale the system to 500 Tbps and then to 900 Tps using next-gen chipset.
- Next-Gen Edge Router – This platform provides enterprise services, Ethernet, Broadband, Mobility, and Internet Gateway using Broadcom, Cisco, and UfiSpace hardware. It is deployed it in AT&T production Internet peering network.
- Cell Site Gateway Router – This supports up to 100Gbps Mobility transport to provide the bandwidth demands that come with 5G services. This solution uses hardware from UfiSpace, Broadcom Qumran-AX chips, coupled with the Vyatta NOS software from Ciena. This has been deployed in AT&T’s mobility network.
- Ethernet Mux – This enables aggregation of 1 and 10 Gig access ports to 100 Gig transport. This platform is based on Broadcom’s Qumran-MX chips and uses EdgeCore hardware with Ciena’s SAOS Network Operating System software. This is now live on the Metro Ethernet and fiber footprint.
- Universal CPE – This broadband customer premise equipment today now provides high speed Dedicated Internet and Enterprise SD-WAN services. It uses Intel, Broadcom, Marvell and Silicom to put together a cost-effective and feature-rich device using Vyatta NOS software from Ciena.
- Open ROADM - Open ROADM provides the high speed and high-capacity optical transport supporting our fiber-based broadband and 5G backhaul. We have Open ROADM compliant components developed from Ciena, Cisco, Fujitsu, Infinera, and Nokia and have installed over 75+ nodes and turned up 100G and 400G wavelengths in our production network.
