Although the Internet of Things (IoT) introduces remarkable ways to collect, manage, and apply data, it's also a huge vector for cyberattacks. One of the biggest vulnerabilities lies in embedded ...

Bletchley Park firm 4Links has created a hardware TCP/IP stack that runs in an FPGA. Initially aimed at its SpaceWire communications protocol, the design could have applications in other areas, where ...

It's easy to miss neat features that get added to really broad products, because they don't get publicized as the most important thing about the release. But the under-publicized features can also be ...

Bletchley Park firm 4Links has created a hardware TCP/IP stack that runs in an FPGA. What is TCP/IP? Transmission control protocol/Internet protocol (TCP/IP) was devised as a standard for linking ...

TCP/IP is a layered networking protocol, which means that packets of data from the application are passed through several stages, or layers, until they move onto the wire as pulses or into the air as ...

Embedded devices, especially those designed for industrial automation that have long shelf lives, are known to use a mixture of in-house and third-party code that was created at a time when software ...

Microsoft has patched a serious vulnerability in the Windows TCP/IP stack that, under some conditions, could enable an attacker to run code on remote machines. The flaw lies in the way that the stack ...

Take advantage of TCP/IP options to optimize data transmission Your email has been sent By Alex Kuznetsov, Alex Plant, and Alexander Tormasov Last time, we explained how the TCP_CORK option can ...

In a previous article, we explained how you can use the sendfile() syscall to reduce the overhead of data transfer from a disk to a network. Now, we’re going to cover another aspect of network ...

Bob Briscoe (Chief researcher at the BT Network Research Centre) is on a mission to tackle one of the biggest problems facing the Internet. He wants the world to know that TCP (Transmission Control ...
