The Routing Wall Of Shame – Ieee Spectrum

If the Internet Could Speak: ‘I’m Melting! Melting!’ | Internet | TechNewsWorld

Router supplier Cisco warned about a need to upgrade routers on its blog back in May when the global routing table passed 500,000 routes. It also laid out what its customer could do to upgrade their Cisco kit or perform workarounds. Last week, with the 512K milestone seemingly reached, Cisco posted another blog saying that it was really time to take action to avoid any performance degradation, routing instability, or impact to availability. In highly simplistic terms, the root issue is that the vast majority of routers in operation use Internet protocol version 4 (IPv4) which was originally specified to support 512K Internet routes, with an unknown number of them unable (even with workarounds) to address more than that number. A newer router protocol IPv6 exists that allows for the addressing of 340 undecillion unique routes. But using that protocol requires investing in new equipment. If you want to know how big 340 undecillion is, and what some of the concerns are in moving from IPv4 and IPv6, there is a great interview from 2011 done by IEEE Spectrumformer editor Steven Cherry with IPv6 evangelist Owen DeLong of Hurricane Electric, a company which claims to be the largest IPv6 backbone in the world as measured by number of networks connected . I also suggest reading a Spectrum story from 2006 on some of the reasons why migration to IPv6 has been a slow process as well as this piece at the Register from last week.

IT Hiccups of the Week

The new 4G LTE devices use IPv6, by the way, which is why the mobile industry is pushing them so hard. The Role of ISPs Some ISPs are among the companies that have not switched to IPv6, as Tuesday’s meltdown showed. “Moving to IPv6 generally means you have to replace a lot of older hardware and this is an expense many have put off for too long,” Enderle said. However, transiting to a new communications protocol “is difficult when the older protocol has already reached critical mass,” Tirias’ McGregor pointed out. “IPv6 hasn’t really taken off yet, and that is becoming a bigger and bigger problem.” Further, the switchover has to occur in stages. “The entire industry does not just drop one protocol and adopt another overnight,” McGregor continued. “This happens over time as new products are introduced and communications platforms are upgraded.” Upgrading communications platforms is the slower process of the two, because companies want to realize returns on the very heavy investment these platforms require, McGregor said.
