Oracle wants to improve Linux load balancing and failover
Wednesday, 11 July 2018 16:33

Oracle reckons Linux remote direct memory access (RDMA) implementations need features like high availability and load balancing, and hopes to sling code into the kernel to do exactly that.

The problem, as Oracle Linux kernel developer Sudhakar Dindukurti explained in this post , is that performance and security considerations mean RDMA adapters tie hardware to a “specific port and path”.

A standard network interface card, on the other hand, can choose which netdev (network device) to use to send a packet. Failover and load balancing is native.

Dindukurti's work aims to bring that capability to both InfiniBand and RoCE (RDMA

BGP hijacker booted off the Internet's backbone
Wednesday, 11 July 2018 14:04

A year-long effort to stop an accused “bad actor” who hijacked border gateway protocol (BGP) routes has borne fruit, with giant Hurricane Electric and Portugal's IPTelecom joining in cutting off an organisation called Bitcanal.

Dyn detailed the process, which is nearing completion a year after German Internet exchange DE-CIX expelled Bitcanal from its exchanges.

The most recent effort, Dyn notes, was launched by security researcher Ronald Guilmette, who in June documented 39 “deliberately hijacked routes” announced via Hurricane Electric alone.

Huawei won a contract in Oz. Of course there's a whispering campaign
Wednesday, 11 July 2018 08:24

Comment Huawei has won another sizeable contract, this time in Australia, and with it come the all-too-common accusations that the company is a national security risk.

The contract in question is an LTE-based 1800MHz rail radio network worth AU$136m (£76.4m) for the State of Western Australia's Public Transport Authority (PTA). Huawei will build and maintain (but not operate) the network. Physical infrastructure will be constructed by a local partner called UGL.

On a global scale, Huawei appears well-suited to provide the kit – its carrier customer list includes BT, Vodafone, Orange, Bell Canada, Clearwire and others – but it has

Big contenders in the broadband chart this week, but who will be #1? Well, not Britain
Tuesday, 10 July 2018 18:17

Britain's place in global broadband speed rankings has slipped four places to 35th, according to a survey.

With an average speed in Blighty of 18.57Mbps, British broadband lags behind such well-connected nations as Hungary, Andorra and Madagascar – with Singapore topping the table at a whopping average of 60.39Mbps.

On the bright side, we do at least beat China (averaging 2.38Mbps), India (5.19Mbps) and Yemen, which enjoys a truly dismal average download speed of 0.31Mbps.

136 countries were slower than the 10Mbps target speed which Ofcom has decreed will be the threshold for the universal broadband service obligation.

BGP borked? Blame the net's big boppers
Tuesday, 10 July 2018 16:02

The Internet's fundamental routing infrastructure, the Border Gateway Protocol (BGP), is so fragile that errors in one to four per cent of ISP route filters can propagate bad routes.

So says Czech DDOS-defender Qrator Labs, which carried out a project to try and help the Internet community quantify how much of the threat to BGP arises from simple things like router misconfiguration.

The company's Alexander Azimov explained the research in this post at the Asia-Pacific Network Information Centre (APNIC).

The conclusion: you don't need many mistakes to allow BGP hijacks and route leaks to have a serious impact.

Cancelled in Crawley? At least your train has free Wi-Fi now, right?
Monday, 09 July 2018 18:18

Wi-Fi has been creeping its way on to UK trains over the last few years as the government seeks to deal with the issue of mobile dead-zones by getting the train companies to provide free connectivity.

However, very low caps and aggressively throttling can make what is an often already unpleasant train journey all the more frustrating

The project kicked off in December 2016, when the Department for Transport (DfT) agreed with Thameslink, Southern and Great Northern (aka the Triumvirate of Fail, as far as recent experience goes) to amend their franchises to provide train Wi-Fi.

The DfT lobbed the
