ZDNet is available in the following editions:
As the communications industry evolves from a network-centric view of the world to a user-oriented perspective, service providers are transforming their business models to create new revenue opportunities associated with enhanced content and interactive media platforms. This white paper explores the opportunities that exist for service providers as they shift how value is created, managed and monetized in their networks to take advantage of next-generation advertising models.
331 days ago by Alcatel-LucentDenial of Service (DoS) attacks and more particularly the distributed ones (DDoS) are one of the latest threat and pose a grave danger to users, organizations and infrastructures of the Internet. Several schemes have been proposed on how to detect some of these attacks, but they suffer from a range of problems, some of them being impractical and others not being effective against these attacks. This paper reports the design principles and evaluation results of proposed framework that autonomously detects and accurately characterizes a wide range of flooding DDoS attacks in ISP network. Attacks are detected by the constant monitoring of propagation of abrupt traffic changes inside ISP network.

First is the consolidation or elimination of these connections, which could require a new, scalable Internet portal architecture that meets all security and communication needs for any agency. Second, the new traffic patterns may require agencies to optimize their routing architecture, and likely compel agencies to create a TIC backbone for access to these portals. Cisco has proven, deployed solutions available to address the architectural challenges agencies face in complying with OMB's mandate. Cisco is prepared to support federal agencies in the planning, testing, and deployment of a TIC-compliant architecture.
354 days ago by Cisco SystemsThe protection of the applications and data that drive business processes and transactions is critical for ensuring business availability, employee productivity, revenue loss avoidance, and brand and corporate reputation protection. As the miscreant economy spreads across all sectors of the economy and threats increase in sophistication and complexity, the protection of missioncritical business assets, applications, data, and processes has become ever more essential. To help service provider security-portfolio managers address these requirements within their customer base, this paper presents an overview of the current trends in the application security market, important drivers and inhibitors of application security, the evolving market landscape, and service provider delivery models for application security solutions.
385 days ago by Cisco SystemsBSNL has two ISP connections BSNL and AIRTEL, in its headquarters and it had Linux based proxy servers. While the Linux based proxy servers failed to do any sort of web content filtering, the load balancing and failover for both the ISP links, was also a tedious manual process. They were looking for a single box solution to all their problems, something that will act as a panacea. BSNL had an easy familiarity with Cisco as most of the hardware came from it. So their first choice was Cisco ASA. Rather, putting it the other way; Cisco did not meet their requirements. They decided to deploy appliance-based, indigenously designed Unified Threat Management (UTM) solution - Cyberoam.
405 days ago by Elitecore TechnologiesISPs provide pipe services, Internet connectivity. They have set up their business to ensure they can carry packets across their network. That's what they lead with when they are out making a sale. Sometimes they happen to offer other ancillary services that they cannot bill, but these services, like DNS, are not specialties or areas of expertise. They are theoretical value-adds. As a network operator, providing a highly available service such as DNS is not their core competency. Managed services like DNS are different from network engineering. While network services require their own expertise with routers and switching, this expertise rarely translates to expertise in services like DNS.
488 days ago by Dynamic Network ServicesThe internet has grown rapidly from a random collection of mainly academic networks and military control and routing protocols into a global, integrated and sophisticated commercial utility. No longer simply an 'Information Superhighway', it has extended to embrace voice telephony, video and mobile communications as part of a converged network. Connection options and services have expanded, with opportunities for Internet Service Providers (ISPs) to add value beyond simply forwarding bit and bytes. This paper explores the challenges and opportunities these companies face and takes a look at how their industry might evolve.
566 days ago by QuocircaInternet Service Providers (ISPs) must interconnect to provide global Internet connectivity to users. The payment structure of these interconnections are often negotiated and maintained via bilateral agreements. Current differences of opinion in the appropriate revenue model in the Internet have on occasion caused ISPs to de-peer from one another, hindering network connectivity and availability. The previous work demonstrates that the Shapley value has several desirable properties, and that if applied as the revenue model, selfish ISPs would yield globally optimal routing and interconnecting decisions. This paper focuses the investigation of Shapley value in networks with two basic classes of ISP: content and eyeball.
576 days ago by Association for Computing MachineryFor the past several years, incumbent telecommunications Service Providers (SPs1) have faced a decline in core legacy revenues, such as fixed-line voice and legacy packet data services in the enterprise and small- and medium-sized business (SMB) markets, which has forced them to move into adjacent markets primarily through acquisitions. Data and voice mobile services and unmanaged fixed data services fueled revenue growth for integrated SPs, but have left a gap in Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA). As a result, SPs have been retooling themselves to move "up the stack" into adjacent market spaces in the information technology value chain such as data center, unified communications, security, other IT-centric services, and advisory services.
597 days ago by Cisco SystemsThis case study shows how a Non-Line Of Sight (NLOS) broadband wireless Internet access system successfully serves a small town / rural market. Motorola Expedience NLOS system is deployed in six rural Iowa locations, including Pocahontas, LeMars, Kingsley, Sheldon, Holstein and Ida Grove, IA. These rural towns range in population from 1,245 to 9,237 residents. This case study focuses on the Kingsley NLOS deployment. This case study describes the Expedience OFDM system commercially deployed in Kingsley, Iowa. One RF base station with a simple antenna installation provides RF coverage for indoor plug-and-play self-install customers in the town and surrounding rural area. An IP-based network architecture supports scalable wireless ISP deployment, from a stand-alone single base station system up to a regional system serving multiple markets.
