C6840-X-LE-40G 6840-X Series Fixed Backbone Switch

Network traffic has grown exponentially over the last several years, and this trend is expected to continue

into the foreseeable future. By 2018, there will be 20+ billion networked devices, up from 10 billion in 2011.

Business IP traffic is expected to reach 13.1 exabytes per month in 2016^[1]. Networks must be capable of

scaling well beyond the needs of today to deal with the traffic of tomorrow while at the same time providing investment protection.
