2013 brings with it more innovations in the networking world. As demands for faster and bigger connections continue apace, the technology will be evolving to meet that demand. Here's a few thoughts on what we expect to see in the New Year.

Big Data = Fast Data

Big Data analytics performance requirements challenge conventional data center network architecture (three-tier, oversubscribed, multi-hop schemas unnecessarily introduces server-server latency). A majority (better than 55% chance) of HPC-like environments will adopt Ethernet fabric architectures at both the network and infrastructure levels to meet the performance demands of enterprise Big Data. These requirements include line-rate, non-blocking and any-to-any communications between devices with massive amounts of flat/leaf-spine East-West traffic optimized for Layer 2.

Virtual Switches Enable Infrastructure Fabrics

Infrastructure Fabrics will be predicated on an increase of up to 10X of server and storage capacity, not just current requirements. They will need to scale beyond the standard VMx8 topology and maintain persistent interlink communications to establish a Fabric-of-Fabrics (FoFs) topology for über-management tracking of performance metrics and scalability risk factors.

"All-you-can-EaT" Bandwidth

Ethernet-as-Transport (EaT) will, by necessity, become a reality. Conventional, often proprietary, data center bridging techniques that are striving to scale Petabytes of capacity, suffer performance and congestion issues due to sub-optimal path-selection algorithms (static hash-based vs. adaptive real-time); slow and unreliable convergence mechanisms upon link failure (lack of cohesive fabrics); and under-utilized bandwidth (conventional switch capacity yields less than 30% utilization).

TRILL is Shrill

TRILL bridging will lose favor to All-you-can-EaT fabrics, given that TRILL requires too many changes to path selection and topology, relies upon static algorithms, and not least, lacks pre-emptive mechanisms for avoiding congestion. EaT Fabrics, by necessity ASIC-accelerated, will gain currency by delivering higher performance Ethernet communications with ultra-low latency and infinite scalability benefits. They are deterministic and offer dynamic multi-path bridging within the fabric that converges at an order of sub-100 nanosecond transmission speeds across the entire fabric.

Proprietary Ultimately Loses in an iOS/Android World

Networking standards will ultimately succumb to cultural and consumer technology habits, giving way to open standards and dictate convergence. For example, an emerging trend is to leverage the inherent extensibility of TCP to build first-class solutions that work in multi-tiered switching LAN environments without the need for legacy switches. Look for enabling protocols to gain currency, such asThe iWARP protocol, which is routable, robust against packet loss, and enables data flow over long distances, so it can be used in routed LAN/WAN environments and highly compute and data intensive applications that require bandwidth on demand.
