ALPN is able to negotiate which protocol should be handled over a secure connection in a way that is more efficient and avoids additional round trips. Computer Science. The disadvantage is the protocol lacks security, which engineers normally can remedy with datagram transport layer security, but DTLS is of limited use in IoT. But while the core of HTTP itself is stateless, HTTP cookies allow the use of stateful sessions. The data in IoT are more complex than in conventional networking. This article focuses on describing different application-layer protocols used in our network model. The Penquin Turla. Cache and authentication methods were functions handled early in HTTP history.
