RFC 8899

General
Internet Engineering Task Force (IETF) G. Fairhurst Request for Comments: 8899 T. Jones Updates: 4821, 4960, 6951, 8085, 8261 University of Aberdeen Category: Standards Track M. Tüxen ISSN: 2070-1721 I. Rüngeler T. Völker Münster University of Applied Sciences September 2020 Packetization Layer Path MTU Discovery for Datagram Transports Abstract This document specifies Datagram Packetization Layer Path MTU Discovery (DPLPMTUD). This is a robust method for Path MTU Discovery (PMTUD) for datagram Packetization Layers (PLs). It allows a PL, or a datagram application that uses a PL, to discover whether a network path can support the current size of datagram. This can be used to detect and reduce the message size when a sender encounters a packet black hole. It can also probe a network path to discover whether the maximum…

RFC 8304

General
Internet Engineering Task Force (IETF) G. Fairhurst Request for Comments: 8304 T. Jones Category: Informational University of Aberdeen ISSN: 2070-1721 February 2018 Transport Features of the User Datagram Protocol (UDP) and Lightweight UDP (UDP-Lite) Abstract This is an informational document that describes the transport protocol interface primitives provided by the User Datagram Protocol (UDP) and the Lightweight User Datagram Protocol (UDP-Lite) transport protocols. It identifies the datagram services exposed to applications and how an application can configure and use the features offered by the Internet datagram transport service. RFC 8303 documents the usage of transport features provided by IETF transport protocols, describing the way UDP, UDP-Lite, and other transport protocols expose their services to applications and how an application can configure and use the features that make up these services.…

Liu Huawei Technologies February 2017 Recommendation on Stable IPv6 Interface Identifiers Abstract This document changes the recommended default Interface Identifier (IID) generation scheme for cases where Stateless Address Autoconfiguration (SLAAC) is used to generate a stable IPv6 address. It recommends using the mechanism specified in RFC 7217 in such cases, and recommends against embedding stable link-layer addresses in IPv6 IIDs. It formally updates RFC 2464, RFC 2467, RFC 2470, RFC 2491, RFC 2492, RFC 2497, RFC 2590, RFC 3146, RFC 3572, RFC 4291, RFC 4338, RFC 4391, RFC…

ECI TruSecc PCC-VPN

General, Research, Technology
ECI TruSecc PCC-VPN Our PCC (Private Communication Ciruit) framework is based on OpenVPN's VPN security model and RealVNC RFB protocol for VNC can be summarized as such: Use the IPSec ESP protocol for tunnel packet security, but then drop IKE in favor of SSL/TLS for session authentication. This allows for a lightweight, portable VPN implementation that draws on IPSec's strengths, without introducing the complexity of IKE. PCC stands for Private Communication Circuit.  PCC’s Benefit a company in the following ways - Extends Geographic Connectivity- a PCC connects remote workers to central resources, making it easier to set up global operations. Boosts Employee Productivity- A PCC solution enables telecommuters to boost their productivity by 22% - 45% (Gallup Organization and Opinion Research) by eliminating time-consuming commutes and by creating uninterrupted time…

Secure Email Options for Message Privacy

General, Technology
Fairly Secure, Actually via Creative Commons Search Many of us had assumed our feeble Gmail passwords were secure enough to keep prying eyes out of our email accounts. But with revelations that the NSA can pretty much demand any email service turn over valuable and private information about our email, more attention has been turning to sources for encrypted secure email services. So what can you use for secure email now?  Email is basically not secure. There are steps you can take to protect yourself, through both free and paid services, but the U.S. government has shown its willingness to compel even legendary secure email services like Lavabit--which Edward Snowden used for five years--to shut down. If you're truly paranoid, here are your options. Instant Messaging Instant messaging, often referred…
