Network Architecture Limitations of Traditional Data Centers
In the traditional data center network architecture, Internet content providers and service providers usually do not establish direct interconnection with each other, and their information needs to be transferred through metropolitan networks, backbone networks and national Internet exchange nodes. Not only are there more hops, but also the geographical area spanned is very wide, so the transmission delay and cost are greatly increased, and the bit error rate is invariably increased, which makes the customer experience greatly reduced.
With the development of Internet of Everything and 5G applications, the demand for network edge nodes has increased significantly, and the proportion of east-west Internet traffic has increased, changing the traditional network architecture has become an inevitable trend. Establishing Internet switching centers in large data centers enables ISPs and ICPs to access the same platform for interconnection, which can avoid unnecessary access hops and inter-network traffic traversal, help reduce transmission costs, increase access speed, and reduce bit error rate, thus significantly improving the network experience of data center customers. In addition, data center is a major energy consumer, and one of the industry's criteria for judging data center performance is PUE. Establishing an Internet exchange, whether it can achieve truly efficient interconnection and savings in resources and overhead, is also a very important criterion for measuring whether a data center is green and efficient.
With the rapid development of mobile Internet and the rapid change of network architecture, the international Internet exchange is already a very mature concept. As of 2018, the number of global Internet exchange centers has rapidly increased to 788. Some of the larger Internet exchange centers are currently AMS-IX, DE-CIX, LINX, Equinix IX, NL-ix, etc. These exchanges are often located in large data centers; put another way, large international data center campuses often have Internet exchanges, and several different exchanges may coexist in the same city or even on the same campus.
Along with the development of the Internet, the establishment of Internet exchange centers in large data centers has become an inevitable market and business development, but many users are still in the awareness stage of Internet exchange centers, and the demand is still insufficient. We should let users understand the applicable scenarios, connection subjects and values realized by the Internet Exchange, and find ways to enhance everyone's trust.
From the applicable scenario, if there is content interaction between two users using the same data center service provider, and the content is not directly linked to the large operator, then it can be directly connected through the Internet Exchange. Simplicity and efficiency are the most fundamental purposes of the Internet Exchange, and also more fully reflect the value of the data center.
In terms of realized value, there is a famous Metcalfe principle in economics, according to which the value of a network is proportional to the squared number of network nodes. The squared number here is mainly the square of the number of nodes that establish directly associated lines. In the Internet Exchange, it helps to increase the overall value of the network by enabling a more direct connection between customers and clients.
When it comes to the Internet Exchange, one question that cannot be avoided is whether it has had an impact on the carrier's traditional business. After all, traffic that used to be bypassed through the operator's network can now be transmitted to its destination with a simple hop through the Internet Exchange. In response to this concern, the introduction of the Internet Exchange is expected to make the market pie bigger, and the traffic diverted by the Internet Exchange instead is far smaller than the overall growth in traffic on the network. "Rather than vacating traffic from the left pocket to the right, it will make the network more optimized and greener, and drive overall traffic growth through efficiency gains and ecological improvements."
