Are all HTTP objects created equal?

You already know that we like to take close look at our traffic to improve our large and growing network. We also share our findings in the global data flow report. This time we analyzed HTTP objects flowing through our network.

DiViNetworksHTTPObjectsTrafficBySourceThe graph shows the percentage of overall HTTP objects flowing downstream in our network. Reminder – our network delivers international data capacity from 15 major Internet exchange points to over 100 ISPs in regions where capacity is expensive.

It’s interesting to compare the HTTP objects mix to the capacity volume mix, as we presented in September 2012.

The winner of the HTTP objects contest – Facebook, reaches 4-6th when it comes to volumes. CDNs such as Limelight and Edgecast, contributing significant volumes, apparently do that with much larger objects, hence do not appear on the HTTP objects map.
Dropbox, on the other hand, is an HTTP pump but at relatively low throughput volumes. My guess – HTTP graph provides early hints to the rise of new content pumps. As Dropbox free storage quota grows, we will see more and more traffic from their AS.
Want another hint? I was very surprised to hear today that Amazon’s traffic is balanced. Yes, their incoming traffic is as big as their outgoing. How come? Perhaps it has to do with Dropbox stored on Amazon’s S3.

Packet Loss – International and Access – Asia, LATAM, Africa

Handling over 100Gbps for over 50 ISPs worldwide, combined with smart devices on international and domestic PoPs, the DiViCloud Network holds a unique view on packet flow in international networks.

We recently are taking a closer look at packet loss on international and domestic links. Surprisingly, high packet loss occurs also during off-peak hours, without any congestion on the line – see results below. Such packet loss results in compromised QoE.

Packet loss – International and Access – DiViCloud’s NYC PoP – Serving LATAM

Packet loss – International and Access – DiViCloud’s Amsterdam PoP – Serving Africa

Summary of the above findings is presented below.

Holding both sides of the link, DiViNetworks can almost eliminate such packet losses, significantly improving end-users QoE.

An interesting case occurred this week, when a carrier providing transport from Singapore to one of our customers, suffered fiber fault. The following figures present the packet-loss rate prior to the fault, and during the fault.

Additional observations are offered in our Global Data Flow Report.

As our earlier blog posts here and here, we discussed global data flow and how we would publish our findings in DiViNetworks’ Global Data Flow Report. DiViNetworks holds a unique point of view – global PoPs positioned at strategic Internet junctions, combined with intelligent software overseeing masses of international traffic. This position enables us to study global data flow characteristics and trends. We would like to share these observations with you.

Below is an example of one of the graphs illustrated in the report to show originating AS source in different regions.

We recently released a first glimpse to our Global Data Flow report. Located at major Internet junctions, the DiViCloud network oversees masses of traffic in different locations, providing us with insights about traffic patterns and sources. Below is an updated graph, which includes information about traffic in S.E.Asia, as well as traffic originating from major local and global carriers.
