This document describes a set of private header (P-header) Session Initiation Protocol (SIP) fields used by the 3GPP, along with their applicability, which is limited to particular environments. The P-header fields are used for a variety of purposes within the networks that the partners implement, including charging and information about the networks a call traverses. This document obsoletes RF...

In this paper we extensively analyze and evaluate the leakage current power dissipation based on the most popular Header/Footer approaches. Five different NanoScale SPICE parameters are used to evaluate each approach in this paper. An efficient approach based on Header/Footer technique to reduce the leakage current and increase the speed operation is proposed. Based on the new approach, it indi...

RFC 6282 defines header compression in 6LoWPAN packets (where "6LoWPAN" refers to "IPv6 over Low-Power Wireless Personal Area Network"). The present document specifies a simple addition that enables the compression of generic headers and header-like payloads, without a need to define a new header compression scheme for each such new header or header-like payload. Information about the current s...

The decision of the inflection point is the key to ensure automatic section cutting precision using a boom-type road header. In this paper, cutting precision model was set up for the first time to trapezoidal section and a method determining inflection point is given. Considered the cutting head’ projection at section is elliptical with the cantilever’s joint variable. The relationship between ...

This document defines an additional mode of the link-layer assisted RObust Header Compression (ROHC) profile, also known as the zero-byte profile, beyond the two defined in RFC 3242. Zero-byte header compression exists in order to prevent the single-octet ROHC header from pushing a packet voice stream into the next higher fixed packet size for the radio. It is usable in certain widely deployed ...

In this paper, we propose and demonstrate a new MicroPhotonic structure for optical packet header recognition based on the integration of an optical cavity, optical components and a photoreceiver array. The structure is inherently immune to optical interference thereby routing an optical header within optical cavities to different photo receiver elements to generate the autocorrelation function...

This document describes a private Session Initiation Protocol (SIP) header field (P-header) to be used by the European Telecommunications Standards Institute (ETSI) Telecommunications and Internet-converged Services and Protocols for Advanced Networks (TISPAN) for the purpose of authorizing early media flows in Third Generation Partnership Project (3GPP) IP Multimedia Subsystems (IMS). This hea...

Overheads associated with MPEG-4 video compressed packets reduce bandwidth efficiency. Mobile operators may save a significant percentage of the required bandwidth using IP header compression technologies, and thereby reduce necessary investments. In this paper, a novel header compression scheme for MPEG-4 video packets is proposed and analysed. It is designed to complement existing IP header c...

Purpose: substantiation of the design cutterbar header, providing high indicators its maintainability and quality sorghum harvesting. Materials methods: scientific works on research cutting devices headers for grain forage harvesters were used. In 2020 harvesting season, timing operation a harvester equipped with segment-finger cutter an endless knife contour segment failure control device was ...
