That is half two of a multi-part weblog sequence on AI. Half one, Why 2024 is the 12 months of AI for Networking, mentioned Cisco’s AI networking imaginative and prescient and technique. This weblog will deal with evolving information heart community infrastructure for supporting AI/ML workloads, whereas the subsequent weblog will focus on the Cisco compute technique and improvements for mainstreaming AI.
As mentioned partially one of many weblog sequence, Synthetic intelligence (AI) and machine studying (ML) have just lately skilled a steep funding trajectory just lately, catapulted by generative AI. This has opened up new alternatives to ship actionable insights and real-world problem-solving capabilities.
Generative AI requires a major quantity of processing energy and better networking efficiency to ship outcomes quickly. Hyperscalers have led the AI revolution with mass-scale infrastructure utilizing hundreds of graphics processing items (GPUs) to course of petabytes of knowledge for AI workloads, similar to coaching fashions. Many organizations, together with enterprise, public sector, service suppliers, and Tier 2 web-scalers, are exploring or beginning to use generative AI with coaching and inference fashions.
To course of AI/ML workloads or jobs that contain massive information units, it’s essential to distribute them throughout a number of GPUs in an AI/ML cluster.

To attain this, it’s important to have a high-performance community that helps non-blocking, low-latency, lossless cloth. With out such a community, latency or packet drops may cause studying jobs to take for much longer to finish, or might not full in any respect. Equally, when working AI inferencing in edge information facilities, it is important to have a strong community to ship real-time insights to numerous end-users.
Why Ethernet?
The muse for many networks at this time is Ethernet, which has advanced from use in 10Mbps LANs to WANs with 400GbE ports. Ethernet’s adaptability has allowed it to scale and evolve to satisfy new calls for, together with these of AI. It has efficiently overcome challenges similar to scaling previous DS1, DS3, and SONET speeds, whereas sustaining the standard of service for voice and video visitors. This adaptability and resilience have allowed Ethernet to outlast options similar to Token Ring, ATM, and body relay.
To assist enhance throughput and decrease compute and storage visitors latency, the distant direct reminiscence entry (RDMA) over Converged Ethernet (RoCE) community protocol is used to help distant entry to reminiscence on a distant host with out CPU involvement. Ethernet materials with RoCEv2 protocol help are optimized for AI/ML clusters with broadly adopted standards-based expertise, simpler migration for Ethernet-based information facilities, confirmed scalability at decrease cost-per-bit, and designed with superior congestion administration to assist intelligently management latency and loss.
In response to the Dell’oro Group, AI networks will act as a catalyst to speed up the transition to greater speeds. Market demand from “Tier 2/3 and enormous enterprises are forecast to be important, approaching $10 B over the subsequent 5 years,” and they’re anticipated to desire Ethernet.
