This article presents OTN evolution from an operator's point of view, including the history of the transport network, the role of the OTN, and the motivations and requirements for OTN evolution. First, a history of transport networks and the role of the OTN in today's networks is reviewed. Next, the motivation for the OTN evolution, operator requirements, and new OTN capabilities are described. Lastly, the future of the OTN is discussed. © 2006 IEEE. Source

Resource sharing among mobile network operators is a promising way to tackle growing data demand by increasing capacity and reducing costs of network infrastructure deployment and operation. In this work, we evaluate sharing options that range from simple approaches that are feasible in the near-term on traditional infrastructure to complex methods that require specialized/ virtualized infrastructure. We build a simulation testbed supporting two geographically overlapped 4G LTE macro cellular networks and model the sharing architecture/process between the network operators. We compare Capacity Sharing (CS) and Spectrum Sharing (SS) on traditional infrastructure and Virtualized Spectrum Sharing (VSS) and Virtualized PRB Sharing (VPS) on virtualized infrastructure under light, moderate and heavy user loading scenarios in collocated and noncollocated E-UTRAN deployment topologies. We also study these sharing options in conservative and aggressive sharing participation modes. Based on simulation results, we conclude that CS, a generalization of traditional roaming, is the best performing and simplest option, SS is least effective and that VSS and VPS perform better than spectrum sharing with added complexity. © 2013 IEEE.

In this paper, we investigate the problem of finding the layer-2 network topology of large, heterogeneous multisubnet Ethernet networks that may include uncooperative network nodes. We prove that finding a layer-2 network topology for a given incomplete input is an NP-hard problem, even for single subnet networks, and that deciding whether a given input defines a unique network topology is a co-NP-hard problem. We design several heuristic algorithms to find network topology, evaluate their complexity, and provide criteria for instances in which the input guarantees a unique network topology. We have implemented one of our algorithms and conducted extensive experiments on the Kent State University Computer Science network. Our experiments demonstrate that our approach is quite practical and discovers the accurate network topology of multisubnet networks whose input may not necessarily be complete. © 2009 IEEE. Source

The security or other attributes of mobile applications may be assessed and assigned a security score. In one implementation, a device may obtain information relating to the mobile applications, and may determine, for each of the mobile applications, a number of security scores. Each of the security scores may define a level of risk for a security category relating to a mobile application. The device may further combine the security scores, for each of the mobile applications, to obtain, for each of the mobile applications, a final security score.

LG put all the rumors to rest and unveiled its 2016 flagship smartphone, the LG G5, to kick off Mobile World Congress 2016. Verizon, AT&T, T-Mobile and Sprint have all confirmed a release on their networks. The LG G5 has been making headlines for months leading up to its official launch. The smartphone was reported to be a major departure from that of its predecessors and those features included a premium unibody aluminum case and first of its kind modular design. In late January, LG tweeted a jab at rival, Samsung, for not including a removable battery in the Galaxy S6, a feature the company offered in each previous model and often used in advertising against Apple's sealed iPhones. The message from LG appeared to confirm its next-gen flagship smartphone; the LG G5 would not compromise such an important feature for a metal design like Samsung and it delivered on that when it unveiled the LG G5 at its press event to kick off Mobile World Congress 2016. The LG G5 features a 5.3-inch 2560 x 1440 Quad HD display with a pixel density of 554 pixels per inch (ppi) and is powered by a Qualcomm Snapdragon 820 processor, Adreno 530 GPU and has 4 GB of RAM. It includes 32 GB of internal storage and a microSD expansion slot that supports up to 2 TB microSD cards, all housed in a sleek aluminum body. The LG G5's camera capabilities include two cameras on its rear, one with a standard 78-degree lens and the other with a 135-degree lens, which allows users to capture images 1.7 times wider than any other smartphone on the market. It also boasts an 8-megapixel front-facing shooter for video calling and selfies. It runs Android 6.0 Marshmallow and ships with a  2,800 mAh removable battery. LG introduced a new modular type design for the G5 that allows users to swap out its battery and add hardware accessories by simply sliding out the bottom of the smartphone. LG has introduced a digital camera add-on that also adds an extra 1,200 mAh battery and Hi-Fi player that rocks B&O Play for enhanced sound. All four major U.S. carriers have officially announced they will offer their customers the LG G5. Verizon will offer the LG G5 in choice of Silver and Titan and has created a registration page where interested customers can sign up to receive information on the smartphone. The carrier hasn't specified an exact release date and notes the LG G5 will be available this spring with select device modules and accessories. AT&T announced it would offer the LG G5 and its accessories and has created a page where it will provide information on pricing and release date in the coming weeks. The carrier will offer the LG G5 in choice of Silver, Titan, Gold, and Pink. T-Mobile has confirmed it will be bringing the LG G5 to its network but hasn't provided any details on pricing, availability, color options beyond a link to LG's official G5 page. Sprint issued a statement confirming it will offer its customers the LG G5. The carrier has created an LG G5 preview page where it will provide pricing and release date information in the coming weeks. The carrier will offer the LG G5 in choice of Silver, Titan, Gold, and Pink. We'll be sure to update you on any new LG G5 details as they become available.
