PHP Scalability and High Availability: Database Resident Connection Pooling and Fast Application Notification
White Paper The OCI8 extension in PHP allows applications to connect to Oracle Database. This paper describes enhancements to PHP's OCI8 extension to use Oracle Database 11g Database Resident Connection Pooling (DRCP) and Oracle Database 10gR2 or 11g Fast... [18 Jul 2008]
Energy-Aware and QoS Routing in 6LoWPAN Mesh Networks
White Paper A routing protocol is needed for the mesh topology approach, which must take into account the very limited features of the network This paper proposes an energy aware QoS routing protocol for 6LoWPAN based on extension of 6LoWPAN Ad Hoc Routing... [18 Jul 2008]
Dynamic Routing in Translucent WDM Optical Networks
White Paper This study follows the current trend in optical networking industry by utilizing extension of IP control protocols. Translucent WDM optical networks use sparse placement of regenerators to overcome the impairments and wavelength contention... [18 Jul 2008]
Autonomous Smart Routing for Network QoS
White Paper The paper also discusses and evaluates an extension of CPN that uses a genetic algorithm to generate and maintain paths from previously discovered information by matching their "Fitness" with respect to the desired QoS. [17 Jul 2008]
Practical QoS Network System With Fault Tolerance
White Paper As an extension of QoS routing, each router is able to compute multiple QoS paths to the same destination. This paper presents an "Emulation environment" for the design and planning of intranets. Intranets must support Quality-of-Service (QoS) for... [17 Jul 2008]
Making the Right Call: Ensuring a Successful IP Telephony Implementation
White Paper Even simple things like being able to transfer your own extension number while visiting a branch office or just being able to have the same phone extension at multiple locations can really add up in terms of cost savings and convenience. [15 Jul 2008]
Bandwidth Extension of Telephone Speech Using Frame-Based Excitation and Robust Features
White Paper This paper develops an innovative solution to bandwidth extension, which is based upon the Linear Source Filter Model that breaks speech up into two parts: the excitation and the spectral envelope. The standards that are still in use for telephone... [11 Jul 2008]
Robust Bandwidth Extension of Noise-Corrupted Narrowband Speech
White Paper This paper presents a new bandwidth extension algorithm for converting narrowband telephone speech into wideband speech using a transformation in the mel cepstral domain. Unlike previous approaches, the proposed method is designed specifically for... [11 Jul 2008]
Efficient High-Frequency Bandwidth Extension of Music and Speech
White Paper The use of perceptually based (lossy) audio codecs, like MPEG 1 - layer 3 ('mp3'), has become very popular in the last few years. However, at very high compression rates the perceptual quality of the signal is degraded, which is mainly exhibited as... [11 Jul 2008]
Architecture and Compiler Optimizations for Data Bandwidth Improvement in Configurable Processors
White Paper While steady progress has been made in the tools and methodologies of automatic instruction set extension for configurable processors, the limited data bandwidth available in the core processor (e.g.the number of simultaneous accesses to the... [11 Jul 2008]
Bandwidth Allocation and Session Scheduling Using SIP
White Paper This paper suggests the extension of SIP functionalities to coordinate QoS mechanisms deployed in IP networks, and especially in DiffServ domain. Session Initiation Protocol (SIP) is a new signaling protocol designed to establish multimedia... [11 Jul 2008]
A Gateway-Based Defense System for Distributed DoS Attacks in High-Speed Networks
White Paper The current network equipments are lack of the countermeasure capacity to such kind of DDoS attack and do not provide the mechanisms to support the extension of the new DDoS attack countermeasures. This paper describes a defense system to contain... [11 Jul 2008]
A Bandwidth Determination Method for IPv6-Based Networks
White Paper This paper presents a method to accurately and efficiently determine the network bandwidth in IPv6 networks through the use of a proposed timestamp option for the IPv6 hop-by-hop extension header. Accurate measurement of bottleneck and available... [11 Jul 2008]
Load Balancing Over Multipaths Using Bandwidth-Aware Source Scheduling
White Paper This paper proposes an extension to SCTP featuring support for bandwidth-aware load balancing over multiple paths. Such extension may be useful to improve the throughput of data transfers when more than one path, spanning heterogeneous wireless... [10 Jul 2008]
IEEE802.3af Power Over Ethernet: A Radical New Technology
White Paper It has just become an international standard, called IEEE802.3af, as an extension to the existing Ethernet standards. Power Over Ethernet technology allows IP telephones, wireless LAN Access Points and other appliances to receive power as well as... [10 Jul 2008]
