CSMA and media access control
Si dividimos un sistema de comunicación genérico en sus partes más “simples” podemos distinguir cuatro elementos: Un emisor, un receptor, un mensaje y un medio o canal para comunicarlo. Uno de los problemas que surgen desde que se establece la comunicación es el acceso al medio. Cuando tenemos un canal de comunicación compartido entre varios usuarios o estaciones es necesario contar con un...
DTLS security over UDP
DTLS (Datagram transport Layer Security) is a protocol that provides privacy for UDP communications. To understand DTLS, you first need to understand UDP. UDP (User Datagram Protocol) is a transport layer protocol based on the exchange of datagrams (encapsulated in OSI model Layer 4 or transport layer). It allows datagrams to be sent over the network without first establishing a connection to...
Why Apache Kafka?
These days, numerous applications follow a microservices architecture. And many applications manage large amounts of data (user activity on the application, logs, metrics, etc.) that are constantly travelling back and forth between microservices. This can produce a series of problems when it comes to integrating all this information – such as the synchronization, scaling and processing of the...
