		<description><![CDATA[https://hackaday.com/2026/07/01/udp-broadcasting-and-easily-finding-network-services/

Local area networks (LANs) that use technologies like Ethernet and Wi-Fi are incredibly useful for letting devices talk with each other. Yet a core problem here is knowing which devices are where on the network, as anyone who has ever tried to add a network printer or network share to their system can probably attest to. Unless you happen to know the IP address of the LAN device, the port, and protocol, the target device may as well be located on the Moon without further help, such as automatic network discovery in lieu of waddling over to the device and reading the label listing its IP address.

Over the decades quite a few ways have been developed to enable such network discovery, with many of them using UDP broadcast as the first step. By broadcasting a global message on the entire LAN, any device that has an actively listening UDP socket on that particular port can parse said message and decide whether it’s feeling sociable enough to reply.

The topic of UDP broadcasting is however not as straightforward as it may sound if you’re just getting started, including the existence of many opinions on the ‘right way’. There is also a massive divide between a sprawling service discovery protocol like mDNS and a light-weight one like that one that I had to implement a few years ago for an open source project.]]></description>

		<description><![CDATA[Salaus ja determinismi suoraan Ethernet-sirulle
https://etn.fi/index.php/13-news/18896-salaus-ja-determinismi-suoraan-ethernet-sirulle

Microchip on julkistanut uuden sukupolven yhden parikaapelin Ethernet-piirit, jotka tuovat kyberturvan, deterministisen tiedonsiirron ja toiminnallisen turvallisuuden FuSa-ominaisuudet suoraan Ethernetin fyysiseen kerrokseen. LAN878x- ja LAN888x-perheet on suunnattu erityisesti ohjelmistomääriteltyihin autoihin sekä teollisuuden kriittisiin verkkoihin.

Kyse ei ole enää pelkästä verkkopiiristä. Uudet 100BASE-T1- ja 1000BASE-T1-PHY:t integroivat suoraan laitteistotason MACsec-salauksen IEEE 802.1AE2018 -standardin mukaisesti. Tämä tarkoittaa, että Ethernet-linkin salaus, datan eheys ja replay-suojaus toteutetaan PHY-piirissä ilman erillistä ohjelmistokuormaa tai lisälatenssia.

Samalla piirit tukevat natiivisti Time-Sensitive Networking -tekniikkaa, jonka avulla Ethernet-liikenteestä voidaan tehdä reaaliaikaista ja ennustettavaa. Tämä on keskeistä esimerkiksi ADAS-järjestelmissä, kameraverkoissa, zonal-ohjaimissa ja robotiikassa, joissa datan täytyy saapua tarkasti oikeaan aikaan.

Microchipin ratkaisu kertoo laajemmasta muutoksesta autoteollisuudessa. Perinteiset väylät kuten CAN, LIN ja FlexRay väistyvät vähitellen täysin Ethernetiin pohjautuvien arkkitehtuurien tieltä. Samalla myös Ethernetin fyysinen kerros muuttuu aiempaa älykkäämmäksi.]]></description>
