Here is another update of our IPv6 traffic. Averaged over the last year, the IPv6 traffic is about 5% of the overall Internet traffic we have. This is pretty good given the fact that only some parts of Jacobs' network currently advertises IPv6. In particular, we have no IPv6 in the student dorms (and the graph clearly suggests that students are a major contributor to our Internet traffic - in particular during finals periods).
A RPL-MIB implementation, based on draft-sehgal-roll-rpl-mib-06, has been completed for the Contiki SNMP agent. An AVR Raven mote has been deployed for testing the MIB and is reachable via the following information:
Hostname: rpl-mib.eecs.jacobs-university.de Port: 1610
If using the Net-SNMP tools, you can retrieve all the MIB objects by using the following:
$ snmpwalk -v 1 -c public udp6:rpl-mib.eecs.jacobs-university.de:1610 1The current RPL-MIB implementation is hosted under the Jacobs University private enterprise OID number. As such, in order to render the numeric OIDs you must install the JACOBS-SMI and JACOBS-RPL-MIB modules.
A LOWPAN-MIB implementation, based on draft-schoenw-6lowpan-mib-03, has been completed for the Contiki SNMP agent. An AVR Raven mote has been deployed for testing the MIB and is reachable via the following information:
Hostname: 6lowpan-mib.eecs.jacobs-university.de Port: 1610
If using the Net-SNMP tools, you can retrieve all the MIB objects by using the following:
$ snmpwalk -v 1 -c public udp6:6lowpan-mib.eecs.jacobs-university.de:1610 1The current LOWPAN-MIB implementation is hosted under the Jacobs University private enterprise OID number. As such, in order to render the numeric OIDs you must install the JACOBS-SMI and JACOBS-LOWPAN-MIB modules.
Our IPv6 traffic keeps growing, reaching new records since the students are back on campus. Even our outgoing traffic is on the rise. Perhaps Jacobs should go ahead and start making their core services (e.g., the official Jacobs web pages) IPv6 ready as well.
There has been a very positive tendency in the amount of traffic shipped over IPv6. Following the winter break, the amount has increased steadily, and its amount is almost three-fold now, compared to the daily averges of summer 2011. The amount of outgoing IPv6 traffic is still, as expected, very low.
Our group applied to participate in the "International IPv6 Application Contest 2011" held by the German IPv6 Council. According to the official page of the Council: "The objectives of this contest are the generation of ideas and applications, which help determine how to introduce IPv6, the Internet of the next generation, on a large scale and use it effectively. The contest also provides an opportunity for the next generation of application developers to gain experience with IPv6." In accordance with the motto of the contest: "Online on the Road - the new IPv6 Standard as driving forces for mobile communication", our group submitted a Simple Network Management Protocol (SNMP) implementation for constrained devices, using the 6LoWPAN adaptation layer for IEEE 802.15.4 wireless links. The implementation carries SNMP messages over UDP/IPv6.
Almost three months passed since the "World IPv6 Day", and the amount of IPv6 traffic has been almost steady since its first increase on that day.
Yesterday, on June 8th, we enjoyed the World IPv6 Day. Here is how the IPv6 traffic changed during the day (measured on the tunnel connecting Jacobs' IPv6 network to the German research network).
Apparently, some very popular web sites like Google and Facebook turned off IPv6 right after the day again. This is probably not so good news… For comparison purposes, here is a plot showing all traffic (IPv4 and IPv6) going in and out of Jacobs University around the World IPv6 Day.
