Description
Every click, swipe and scroll leaves an impact on the environment. As we rely more on the Internet in many sectors and for many applications, the carbon footprint of the internet is rising, and it is unclear if we can achieve the net zero goals by 2050. Introducing carbon awareness to computer networks is one promising solution, yet with many challenges. The work presented in this talk is in the context of fixed wired networks, where accounting for their emissions is hard, requires changes to deployed equipment, and has contentious benefits. The talk has shed light on the benefits of carbon aware networks, by exploring a set of potential carbon-related metrics and their use to define link-cost in carbon-aware link-state routing algorithms. Using realistic network topologies, traffic patterns and grid carbon intensity, it identified useful metrics and limitations to carbon emissions reduction. Consequently, a new heuristic carbon-aware traffic engineering algorithm, CATE, was proposed. CATE takes advantage of carbon intensity and routers’ dynamic power consumption, combined with ports power down, to minimize carbon emissions. The presented results show that there is no silver bullet to significant carbon reductions, yet there are promising directions without changes to existing routers’ hardware. The talk uncovered some of the challenges that Internet Service Providers (ISPs) will need to face as we move towards net-zero networks.
