Cisco has amped-up its support for 800G capability networks with an eye towards helping big enterprises, cloud and company deal with the anticipated need from AI, video, and 5G services.At the core of
its recently advancements is a new 28.8 Tbps/ 36 x 800G line card and improved control software for its high-grade Cisco 8000 Series routers.The 28.8 T line card is built on Cisco’s Silicon One P100 ASIC, and brings 800G capability to the modular Cisco 8000 Series Router, which can scale to 230Tbps in a 16 RU type aspect with the eight-slot Cisco 8808, and as much as 518Tbps in the 18-slot chassis, according to Cisco.Improving space and energy usage while bulking up densities are also part of the new line-card’s story, wrote Satish Surapaneni, director, product management, with Cisco’s Networking, Company Connectivity group in a blog site about the 800G improvements.
The cards can support 36xQSFP-DD800 ports, which can make it possible for the use of 2x400G and 8x100G optics, and deliver densities with 72x400G ports or 288x100G ports per slot. “The factor we can double the density is because the P100 uses advanced 100G SerDes innovation that can attain greater bandwidth speeds in the same footprint,” Surapaneni stated.So rather
of 6 400G modular systems, one 800G eight-slot modular system can achieve 230Tbps with approximately 83% space savings, as much as 68% energy savings, or about 215,838 kg CO2e/year (green home gases) savings. “To put it in perspective, these carbon savings are the equivalent of recycling 115 lots of waste a year rather of entering into land fills,” Surapaneni specified.
In addition to sustainability and operational cost benefits, consumers can protect their pluggable optics financial investments because Cisco QSFP-DD 800G is backwards compatibility to lower-speed QSFP-DD and QSFP modules, Surapaneni mentioned.
On the software side, Cisco bolstered its Crosswork Network Automation software application that consists of tools to monitor and validate network operations, gather and correlate data to recognize network trends and patterns, and automate operations. This enables quicker provisioning, and supplies innovative visualization dashboards, services keeping an eye on, and better network optimization, Surapaneni mentioned.
Cisco is likewise including a brand-new feature to the 8000’s IOS XR os. IOS XR Sector Routing innovations with Course Tracing offers hop-by-hop presence into packets are flow to help identify and repair issues and promote expense reduction, Surapaneni stated.Introduced in 2019,
the Silicon One household of unified switches and routers is essential to Cisco’s goal of network foundations of big webscale and service-provider networks. Silicon One optical-routing silicon consists of assistance for large non-blocking dispersed routers, deep buffering with abundant QoS, and programmable forwarding. The Silicon One household lets Cisco compete with others such as Intel, Broadcom, Juniper, and Arista in building high-capacity networks.” Given that traffic volumes are increasing, higher capacity is needed at the network intersection points, such as in the core. These core networks are in the IP backbone and city areas, where we’re seeing more traffic focusing, as applications and services move more detailed to the user, user gain access to speeds increase with fiber and 5G, and functionality such as peering, subscriber management and CDN get dispersed in your area,”Surapaneni specified.” To prevent traffic congestion with network congestion, a scalable city core is needed to transport all traffic types, especially high-bandwidth latency-sensitive traffic, “Surapaneni states.”However, city places tend to be smaller sized with tighter area constraints, which is why area effectiveness is critical. Scaling to 800G can assist suppliers address … Source
