A model for delay evaluation and minimization in paths composed of logic gates and RC wires is presented. The method, Unified Logical Effort (ULE), provides closed-form conditions for timing optimization while overcoming the breakdown of standard logical effort (LE) rules in the presence of interconnect. The ULE delay model unifies the problems of gate sizing and repeater insertion: In cases of...

The MPEG-2 standard defined by ISO 13818-1 supports a range of transmission methods for a variety of services. This document provides a threat analysis and derives the security requirements when using the Transport Stream, TS, to support an Internet network-layer using Unidirectional Lightweight Encapsulation (ULE) defined in RFC 4326. The document also provides the motivation for link-layer se...

The MPEG-2 Transport Stream (TS) has been widely accepted not only for providing digital TV services, but also as a subnetwork technology for building IP networks. This document describes a Unidirectional Lightweight Encapsulation (ULE) mechanism for the transport of IPv4 and IPv6 Datagrams and other network protocol packets directly over the ISO MPEG-2 Transport Stream as TS Private Data. ULE ...

This document describes a set of Extension Headers for the Unidirectional Lightweight Encapsulation (ULE), RFC 4326. The Extension Header formats specified in this document define extensions appropriate to both ULE and the Generic Stream Encapsulation (GSE) for the second-generation framing structure defined by the Digital Video Broadcasting (DVB) family of specifications.

A new optical fiber and method of manufacturing the same developed for use with surgical laser systems. The fiber core utilizes an ultra-low expansion (ULE) material. The preferred ULE fiber consists of silicon dioxide core doped with titanium dioxide which is cladded and jacketed for chemical and abrasion resistance. The resulting fiber is stable against degradation due to thermal expansion.

There is growing interest in providing multimedia and broadband access over satellites. However there are several technical challenges need to be addressed. One challenge is security in terms of understanding threats and providing an effective security system. Also this paper presents a ULE security solution using ULE mandatory extension headers. The design issues and choices are discussed. The...

The unified logical effort (ULE) model for delay evaluation and minimization in paths composed of CMOS logic gates and resistive wires is presented. The method provides conditions for timing optimization while overcoming the limitations of standard logical effort (LE) in the presence of interconnects. The condition for optimal gate sizing in a logic path with long wires is also presented. This ...
