If you’re using a Virtual Private Network (VPN), you may find that the speed drops when a TCP connection is used within another TCP connection. Since most internet traffic is still TCP-based, it’s better to set up a UDP-based tunnel, through which DTLS will improve the performance of...
DTLS works with the user data protocol (UDP) — which supports data transfers across networks — to provide a secure, rapid connection for live messaging and broadcasting. So, what is the transport layer? The transport layer is a part of networking and appears in both the OSI model (Open ...
Secondly, a VPN shields all the personal data you send and receive from those who might try to harvest it, by rerouting your Internet traffic through a safe server. Some of that private information might include geographic location, your IP address, browsing habits, device information and many ...

Notification receiptTLS/DTLS10162 Why do you need SNMP monitoring tools? Network admins manage the devices in a network and allocate or release ports, interfaces, and more to ensure continuous uptime and bandwidth-hog-free network operations. Closely monitoring SNMP devices is a significant part of...
(TURN). TURN basically relies on an external server to reroute the connection so communication can be established. It relays all traffic between the two devices through that server, which increases latency and bandwidth but ensures a connection. Again, for our hotel analogy, TURN is like an ...
DTLS 1.3 introduces a very efficient “unified header”. This new header format also obfuscates the epoch and sequence numbers to make traffic analysis harder. 0 1 2 3 4 5 6 7+-+-+-+-+-+-+-+-+|0|0|1|C|S|L|E E|+-+-+-+-+-+-+-+-+| Connection ID | Legend:| (if any...
WhatsApp is using thePJSIP libraryto implement Voice over IP (VoIP) functionality. The captures shows no signs of DTLS, which suggests the use of SDES encryption (seeherefor Victor’s past post on this). Even thoughSTUNis used, the binding requests do not contain ICE-specific attributes. ...
Once an IoT device has been configured and begins to operate, most of its traffic is outbound. A security camera, for example, streams video data. Likewise, an industrial sensor streams sensor data. Some IoT devices such as smart lights, however, do accept inputs. ...
(TLS) protocol, which is the widely used successor to Secure Sockets Layer (SSL). The libssl library still supports SSL version 3, but only as a compile-time option. In addition, the library provides implementations of the Datagram TLS (DTLS) protocol and the Quick UDP Internet Connections ...
