Why Intel continues to make money while PCs nose-dive, in two words

We normally think of Intel as the engine of the PC. But as Intel proved on Tuesday, the company can keep increasing revenue even as the PC market declines—and if it ever recovers, Intel’s business is poised to take off.Why? Data centers.Intel’s consumer processor division, called the Client Computing Group, still makes up close to 60 percent of its business—$8.51 billion in total third-quarter revenue, compared to $4.1 billion for its Data Center Group. But while CCG profits fell by 20 percent that quarter, Intel still recorded flat revenue because profits at DCG, which include SSDs and Xeon chips, are up 9.3 percent.To read this article in full or to leave a comment, please click here

Global Impacts of Recent Leaks

65.54.215.0_24_1444474800

Recent routing leaks remind us why monitoring Internet routing and performance is important and requires effective tools.  Routing leaks are the ‘benign cousin’ of the malicious BGP route hijack.  They happen accidentally, but the result is the same: traffic to affected prefixes is redirected, lost, or intercepted.  And if they happen to you, your online business and brand suffers.

In this blog, we look at examples of a full-table peer leak, an origination leak, and a small peer leak and what happens to traffic when these incidents occur.  As we will see, some events can go on for years, undetected and hence, unremediated, but extremely impactful never the less.  As you read this blog, keep the following  questions in mind.  Would  you know if the events described here were happening to you?  Would you know how to identify the culprit if you did?

 

iTel/Peer1 routing leak

Starting on 10 October at 10:54 UTC, iTel (AS16696) leaked a full routing table (555,010 routes) to Peer 1 (AS13768).  Normally, iTel exports 49 routes to Peer 1;  however, over the course of several minutes, it leaked 436,776 routes from Hurricane Electric (AS6939) and 229,537 Continue reading

Save some bandwidth by turning off TCP Timestamps

This is a guest post by Donatas Abraitis, System Engineer at Vinted, with an unusual approach for saving a little bandwidth.

Looking at https://tools.ietf.org/html/rfc1323 there is a nice title: 'TCP Extensions for High Performance'. It's worth to take a look at date May 1992. Timestamps option may appear in any data or ACK segment, adding 12 bytes to the 20-byte TCP header. 

Using TCP options, the sender places a timestamp in each data segment, and the receiver reflects these timestamps back in ACK segments. Then a single subtract gives the sender an accurate RTT measurement for every ACK segment.

To prove this let's dig into kernel source:

./include/net/tcp.h:#define TCPOLEN_TSTAMP_ALIGNED    12
./net/ipv4/tcp_output.c:static void tcp_connect_init(struct sock *sk)
  ...
  tp->tcp_header_len = sizeof(struct tcphdr) +
    (sysctl_tcp_timestamps ? TCPOLEN_TSTAMP_ALIGNED : 0);

Worth Reading: Digital Content and the Fate of Businesses

There are two key differences between buying media in a physical format versus a digital one. First, there’s the technical aspect: Maintaining long-term access to a file requires a hard copy of it—that means, for example, downloading a film, not just streaming from a third party’s server. The second distinction is a bit more complicated, and it has to do with how the law has shaped digital rights in the past 15 years. It helps to think about the experience of a person giving up CDs and using iTunes for music purchases instead. —via the atlantic
