In the U.S. and Canada have providers Tuesday suffered from slow or dropped connections. Cause would be legacy routers that can’t handle bgp-routingtables that more than 512.000 entry’s contain and this crash or new routes are no longer accepting.
Through the border gateway protocol internetrouters a continuous supply of routing. These routes should traffic in a good direction. Outdated routers may, however, not more than 512.000 routes in the ternary content addressable memory, a specific area of memory in routers in which the routing table is stored. Get the routers to do more than the 512K of entry’s, then may cause a paper jam. Also, the devices are no longer new routing want to accept or is switched to a softwaremodus with a lot of lag can arise.
Tuesday seems this problem head on to be plugged now, the number of routes has grown to about 512.000. In the US and Canada were carriers for a few hours with intermittent internet connections or unreachable hostingpartijen, reports ZDnet. This was the site of LastPass for some time offline as a result of an unreachable host. A number of major carriers has already admitted that the bgp-problems with older routers have played a role. The isps say measures have been taken to resolve the issues.
It is striking that many providers are only now decide to intervene. In march, an ipv4-reseller already know that the chance was large that the 512K problem sometime in August to november should reveal. Also, network providers such as Cisco have their customers be warned. However, it seems that many companies have outdated routers not or not in time be replaced by routers that can handle the ever-growing routing tables that the internet traffic upright have to keep.
