Internet usage patterns have evolved from web/text based usage to a high concentration on video. This has led to a sudden spike in traffic and the number of heavy users.
Multimedia traffic becomes more dominant in both fixed and mobile, accounting for approximately 70% and 53% respectively. This pattern is expected to further escalate.
According to Cisco, video is expected to consume 91% of the global traffic by 2014.
The growth in mobile traffic is much faster than the increase in the number of subscriptions. In fixed service, the subscription increased approximately 25% for the past 6 years, from 6.28 million to 7.82 million, meanwhile the traffic increased by 550% from 380Gbps to 2,090Gbps.
In mobile, the subscription increase is minimal compared to the 2009 level – with an annual growth of 5% – however the traffic has increased by 153 fold, due to the introduction of flat rate.
Within the fixed service, 5% of all users account for 55% of all traffic while in mobile 5% consumes 50% of total traffic causing inconvenience for many other users.
Increase in Over-the-Top (OTT) service providers who utilize the network without sharing the burden of investment further deteriorates the profitability of carriers.
In line with these evolving trends, new rules on trade order are required for the healthy development of the whole ecosystem.
While most new services and devices use the fixed/mobile network, the value of the network itself is underestimated. The investment is solely for the carriers while benefit/profit is shared with traffic generators or service providers.
The service providers, who profit from using the fixed/mobile network and in the process generates huge traffic, should bear their fair share of the cost.
When the traffic generator/beneficiary pays principle is put in place, the tragedy of the commons can be prevented and ICT ecosystem can be further advanced.
Therefore, massive and high-frequency traffic needs to be managed in a reasonable and transparent manner to promote virtuous cycle within the ICT ecosystem.
When a particular service, such as P2P and Smart TV, is suspected to cause massive traffic on the network, it needs to be managed to relieve network congestion. Also, as high-frequency traffic including signaling can cause serious strain on the overall network performance, some form of intervention might be necessary.
A possible solution could be standardization of mobile traffic.
A standardized usage may prevent unnecessary social cost from incurring, as it can promote more efficient utilization of the limited resource of mobile networks. Considering the characteristics of network and contents usage, a certain level of traffic trade order needs to be established.
Managed services may also need to be encouraged.
Premium services of enhanced Quality-of-Service (QoS) can be made available for service requiring higher performance. A QoS-dependent pricing structure can facilitate introduction of differential services of varying network and traffic values.
Most importantly, all the interested parties should promote virtuous development in the ICT ecosystem by exploring a mutually beneficial model.
