Scalability discussions are focused around how to future-proof the network. The answer has historically been to purchase bigger boxes upfront or connect multiple boxes in an endless chain as port requirements grow. As bandwidth needs to expand, the port count needs to be matched with throughput speed. It does not help to add ports if you do not have the bandwidth to support the available ports. Consequently, switches, tools and packet brokers are becoming bigger and faster to support the ports and bandwidth. The question to ask today, however, is are manufacturers overshooting the market?
