The carrier wholesale market is an evolving industry with content moving closer to the edge and interconnection bandwidth set to surge. Capacity looks at some key trends from 2017, which includes the increasing threat of DDoS attacks
Akamai Technologies’ first quarter 2017 State
of the Internet Report is based on data gathered from the
Akamai Intelligent Platform.
The report provides insight into key global statistics such
as connection speeds, broadband adoption metrics, notable
Internet disruptions, IPv4 exhaustion and IPv6
"Increases in connection speeds and broadband penetration
have helped enable the internet to support levels of traffic
that even just a few years ago would have been unimaginable,"
said David Belson, editor of the State of the Internet
"One need only look to January’s US
Presidential Inauguration, which broke traffic records for live
coverage of a single news event delivered by Akamai, largely
thanks to the combination of more viewers watching at
increasingly higher levels of video quality."
Akamai saw a 0.9% quarterly increase in the number of unique
IPv4 addresses connecting to the Akamai Intelligent Platform,
rising to just over 814 million, about 7.6 million more than in
the fourth quarter of 2016. About 5 million IPv4 addresses were
depleted from available pools at the regional internet
registries in the first quarter, leaving 39 million addresses
remaining. Belgium remained the clear global leader in IPv6
adoption with 38% of its connections to Akamai for dual-stacked
content over IPv6, down 19% from the previous
DE-CIX and AMS-IX reach 5Tbps
Content provider networks increasingly supply content closer
to the network edge in order to reduce latency for localised
traffic. To support this effort, companies like Facebook,
Google, and Microsoft have strategically deployed proprietary
data centres across the globe while also investing heavily in
network and colocation infrastructure.
Among the small group of content providers depicted here
(right) by TeleGeography, 14 new proprietary data centres were
deployed globally in 2016 , and a further 23 are scheduled for
launch within the next few years. Core IXs peering points are
hitting new peaks in traffic volumes, with DE-CIX (Frankfurt)
and AMS-IX (Amsterdam) each exceeding 5Tbps in peak traffic
Interconnection bandwidth to hit 5,000Tbps by
Interconnection bandwidth is expected to grow at a 45% CAGR
to reach 5,000Tbps by 2020, dwarfing global IP traffic in both
growth (24%) and volume (855Tbps), according to
Equinix’s inaugural Global Interconnection
Findings from the Global Interconnection Index, which has
analysed the adoption profile of thousands of carrier-neutral
colocation data centre providers and ecosystem participants
globally, show that the capacity for private data exchange
between businesses is forecasted to outpace the public internet
by nearly two-times in growth and six-times in volume by 2020.
It is also growing faster than Multiprotocol Label Switching
(MPLS), the legacy model of business connectivity, by a factor
of 10 (45% to 4%).
"Interconnection bandwidth is expected to grow at a rapid
pace over the next four years with growth across all regions
predicted to grow 40% per annum or greater," stated the
Increase in frequency:
We have passed the first anniversary of what many believe to
be one of the largest DDoS attacks recorded. Domain name
service provider Dyn came under attack by two large and complex
DDoS attacks against its managed DNS infrastructure. Because of
the attacks, dozens of internet platforms and services
– including major brands such as Twitter, Spotify,
Reddit, Netflix and others – felt the significant
ripple effect of service outages.
Since that incident, other various large-scale DDoS attacks
have made national or global headline news. However, those
large-scale attacks are atypical of the types of disruptions
that companies suffer from day to day. Frequent, modest-sized,
short duration DDoS attacks are the modern-day problem, as they
regularly cause the most damage. It’s these types
of attacks on which businesses should focus.
Corero has observed a jump in the frequency of attack
attempts against customers. In Q3 2017, Corero customers
experienced an average of 237 attacks a month, an increase of
35% compared with Q2 2017 (175 attacks). Worryingly, Corero saw
an average of eight attack attempts per customer per day in Q3
2017 – double what was observed in Q1 2017.
Low volume, short duration attacks:
While the frequency of attacks is concerning, the size and
duration of attacks are also important to call out. Roughly 96%
of mitigated DDoS attacks were less than 5Gbps in volume, in
both Q2 and Q3 2017.
The average duration of DDoS attacks is also cause for
concern: 65% of attacks in Q2 2017 lasted 10 minutes or less,
and in Q3, 71% were 10 minutes or less.
While attacks lasting five minutes or less make up the
majority of the attack attempts, we noticed that attacks
lasting 21-30 minutes dropped by 50% (Q1 versus Q3).
