Status of this Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract This document describes different scenarios in Third Generation Partnership Project (3GPP) defined packet network, i.e., General Packet Radio Service (GPRS) that would need IP version 6 and IP version 4 transition. ...
Mobile networks pose challenges to quality management because of the limited capacity of the air interface and the mobility of the users. GPRS is the prevailing system for mobile connectivity at the moment. This paper approaches quality management in GPRS networks with a two-phase system, where a detector block first culls quality disturbances and a fuzzy case-based reasoning engine then propos...
Performance Characterization of the 64-bit x86 Architecture from Compiler Optimizations' Perspective
Intel Extended Memory 64 Technology (EM64T) and AMD 64-bit architecture (AMD64) are emerging 64-bit x86 architectures that are fully x86 compatible. Compared with the 32-bit x86 architecture, the 64-bit x86 architectures cater some new features to applications. For instance, applications can address 64 bits of virtual memory space, perform operations on 64-bit-wide operands, get access to 16 ge...
Throughout the world, GSM cellular mobile networks are being upgraded to support the “alwayson” General Packet Radio Service (GPRS). Despite the apparent availability of levels of bandwidth not dissimilar to that provided by conventional fixed-wire telephone modems, the user experience using GPRS is considerably worse. In this paper we examine the performance of protocols such as TCP over GPRS,...
شبکه gprs، یک شبکه مخابرات سیار مبتنی بر بسته می باشد که در واقع یک شبکه اصلاح شده از شبکه gsm است با این تفاوت که این شبکه سرعت انتقال بسیار بالایی دارد که آن را قادر به ارائه سرویس اینترنت می سازد. مفهوم ازدحام در شبکه gprs کمی متفاوت با همین مفهوم در شبکه tcp/ip است. این مفهوم درgprs از دو دیدگاه شبکه و فرستنده می تواند مورد بررسی قرار می گیرد. دراین پایان نامه ازدحام از نوع دوم مورد بررسی و...
Demand for the Internet services through GPRS/3G networks is proliferating day-by-day. But low bit rate puts constraints on multimedia or mobile business services. In contrast, Wireless Local Area Networks (WLANs) provide high bit rate with low deployment cost. Therefore, integration of these two complementary systems would be the focus of next generation wireless networks. However mobility and...
