Bandwidth Transport, Optimization and Protection for Wireless Backhaul: Meeting 3G & 4G Service Delivery Challenges
The legacy TDM/PDH1 based Network Infrastructure is moving to a packet based model characterized by ubiquitous native Ethernet connectivity to an IMS2 based core for the switching and transport of voice, data, and multimedia traffic. This white paper delves into the issues surrounding the transition of the wireless network to an Ethernet / IP architecture and discusses solutions that will enable equipment OEMs and their Service Provider customers to address the challenges they are facing in today's rapidly changing environment.

UMTS and HSDPA are the preferred services in many markets, but challenges with interference and isolation among the RF cells are reducing bandwidth and coverage in dense areas and inside buildings. This paper proposes a supplemental UMTS/HSDPA network architecture that cost-effectively improves service by increasing isolation to reduce interference while increasing data speed bandwidth and coverage. Therefore improving network efficiency and reducing mobile operator production costs.

For the first time in history, one can now aim to live in "One World", because the 1st century has ushered in a new era in man's ongoing quest for a better life and a better world. Telco industry is passing through a phase of multiservice revolution, with a shift from legacy to next generation networks and the introduction of new and advanced services (e.g. DTV, HDTV, IPTV, VoIP, WiMAX, Mobile TV, etc.). More and more service providers are progressing to triple-play and even quad-play packages in order to provide a one-stop shopping service to customers. IP traffic is growing exponentially and networks evolve to include bandwidth hungry IP-based applications on voice, video and data.

The evolution of Internet content toward social media and Web 2.0-based sites presents new challenges for organizations. Critical applications have become Web-based, and non-browser generated Web traffic - think iTunes and peer-to-peer networking - has exploded. One has a business Internet connection for two things: Web-based applications (Web site admin tools, CRM tools, collaboration sites) and Web browsing (to do critical research). Of course, some of the employees use their time and Internet connections for non-critical ends, such as checking personal e-mail or streaming music or video. The trick is to maximize the company's broadband capacity and contain related costs while also protecting the assets from malware and viruses.

The new Data Center Bridging (DCB) protocols provide important mechanisms for enabling priority and managing bandwidth allocations between different types of traffic. However, given their complexity, it can be difficult to discern from standard network operations whether these mechanisms have been implemented robustly or not. This paper will explore key areas of these protocols which require verification and show developers how to test that network equipment performs as expected. The new Data Center Bridging (DCB) protocols currently being developed to carry Fibre Channel, TCP/IP, and IPC traffic over a single, converged 10 Gigabit Ethernet network.

277 days ago by SAPHybridCast: A Hybrid Probabilistic/Deterministic Approach for Adjustable Broadcast Reliability in Mobile Wireless Ad Hoc Networks
Broadcast is a crucial yet expensive building block for many applications in bandwidth-scarce mobile wireless ad hoc networks. The paper proposes a hybrid deterministic/probabilistic, decentralized broadcast protocol with adjustable broadcast reliability and overhead. The paper first proposes a purely probabilistic, topology-aware broadcast algorithm. The probabilistic broadcast adjusts each node's broadcast forwarding probability locally such that the average broadcast reliability requirement is met. An extension of the probabilistic broadcast to tolerate node mobility and packet loss is then presented. Furthermore, the paper augments the proposed probabilistic broadcast scheme with an existing deterministic broadcast protocol in order to reduce excessive broadcast overhead.

Multi-pathing software provides the intelligence necessary to manage multiple I/O paths between a server and a storage subsystem. When configured for redundancy, a single path is dedicated to I/O transfer, while other paths are in standby mode. The software manages failover between the I/O paths, thus eliminating the potential for a single point of failure. If connectivity along one path to a storage device is interrupted, the multi-pathing software dynamically switches I/Os to a surviving path, allowing application access to continue unimpeded. The other mode of operation allows for all paths to be utilized for I/O transfer. This can improve performance by leveraging the presence of these multiple paths, increasing the available bandwidth for I/O traffic.

LTE is an optimized mobile OFDMA solution that continues 3G's track record of mobility and high spectral efficiency. It leverages new and wider bandwidth spectrum to boost data capacity in dense urban areas. 3G and its evolutions will continue to provide ubiquitous broadband coverage outside LTE areas as well as voice services throughout the network. LTE and 3G evolutions provide similar performance as they both leverage the same enhancements. Designed for seamless interoperability with 3G networks and their evolutions, LTE allows operators to capitalize on existing HSPA/EV-DO and future HSPA+/EV-DO Rev. B investments. LTE/3G multimode devices play a pivotal role in LTE deployments. Qualcomm with its industry's first multimode chipset solutions is in a unique position to support timely LTE deployments.
