Global Internet Traffic Growth Results In Soaring Energy Consumption
As global internet traffic grows exponentially, conservative estimates indicate there’s a 30% annual increase in data transmission. This surge results in soaring energy consumption and carbon emissions from IP networks that are under immense pressure to add more network links. However, most routers are limited to 400 Gigabit Ethernet (GE) speeds, causing network footprints to expand as additional interface ports and line cards consume more rack space and energy.
As Network Operators work to find innovative ways to scale networks and meet the ever-increasing demand for bandwidth to fuel the Metaverse, organizations working toward a more climate-friendly world are issuing warnings about the energy consumption required for many of these initiatives. After all, more power fueling the Metaverse means more energy consumption and carbon emissions on a global scale.
800GE Routing Enables Faster, Scalable Networks Without A Larger Footprint
The introduction of 800GE routing is set to change this landscape. It enables network operators to build faster and more scalable networks and upgrade their router interfaces to 800 gigabits per second (Gb/s) without increasing their network footprint. 800GE routing achieves this by utilizing faster and more efficient silicon and optics, allowing networks to move more traffic with less energy per bit without additional interfaces. It also leverages the latest Quad Small Form Pluggable Double Density (QSFP-DD) interface modules that support high-density 800GE pluggable optics and maintain compatibility with existing 400GE, 200GE, and 100GE optics.
800GE routing’s speed and efficiency are achieved through cutting-edge 7nm routing silicon, such as Nokia’s FP5 network processor. FP5 supports the 112Gb/s SerDes electrical signaling interfaces required by 800G QSFP-DD pluggable transceivers, consolidating packet processing, traffic management, high-bandwidth memories, and switch fabric interfaces into a single system on a chip (SoC). The routing silicon plays a critical role in enhancing the capacity, density, and energy efficiency of IP switching fabric, line cards, and interface optics. It also occupies 70% less space than the 16nm FP4 chipset, delivers nearly four times more line rate traffic capacity per line card, and consumes 75% less energy per bit (excluding interface optics).
The FP5 hardware also offers flexibility that allows operators to initially deploy 100GE and 400GE optics and seamlessly upgrade to 800GE when needed to accommodate future traffic growth efficiently.
Benefits of 800GE Routing
As web traffic continues to grow at a staggering rate – with absolutely no signs of slowing down – operators face the challenge of increasing network capacity within the constraints of space, energy, and thermal limits. Large organizations like communications service providers (CSPs), internet exchange providers, or enterprises planning the deployment of 400 Gb/s links should also consider 800GE routing.
This technology offers a significant increase in link capacity compared to current 400GE and 100GE networks and provides the necessary headroom for traffic peaks and future growth while simplifying network complexity and reducing costs.
Space and Energy Efficiency
800GE routing also excels in space efficiency. It effectively doubles interface capacity and connectivity within the same rack space. Additionally, 800GE routing contributes to energy efficiency as it’s more energy-efficient than transporting an equivalent volume of traffic using multiple 400GE or 100GE links, with energy savings ranging between 20 and 40% per Gigabit of traffic.
