Resilient architecture for optical access networks

Photonic Network Communications, 2020
This work proposes a resilient wheel-based wavelength-division-multiplexed passive optical network optical access network architecture for backhauling network traffic. This proposed resilient architecture can efficiently support not only the fixed users but also the mobile users in the downstream direction under normal and failure operating scenarios ...

Clickable Bambusurils to Access Multivalent Architectures

Organic Letters, 2020
Propargylated bambus[4,6]urils were prepared by an efficient one-step condensation of dipropargylglycoluril with formaldehyde under microwave irradiation. Their functionalization by click chemistry (CuAAC) afforded new multivalent architectures decorated with 8 or 12 ligands.

Broadband fiber access: A fiber-to-the-customer access architecture

Bell Labs Technical Journal, 2002
The proliferation of high-bandwidth applications such as high-speed Internet access and telecommuting has created among network providers a growing interest in upgrading their networks to deliver broadband services to homes and small businesses. This paper describes broadband fiber access (BFA), a fiber-to-the-customer access architecture based on ...

An Access Control Architecture for Context-Risk-Aware Access Control: Architectural Design and Performance Evaluation

2010 Fourth International Conference on Emerging Security Information, Systems and Technologies, 2010
Risk assessment plays a significant role in Decision Support Systems (DSS). Recently, there have been efforts to exploit the potential of linking risk assessment to security provisioning to provide risk-aware security services. One of these efforts is the Context-Risk-Aware Access Control (CRAAC) model that links requesters' access privileges to the ...

Architecture of Future Access Networks

2008
A key issue to reach a highly scalable Passive Optical Network (PON) with very high splitting ratio is the high multiplexing level required to handle all individual signals (individual data flows) that travel along shared fibres. The available fibre bandwidth and current high-speed electronics allow high splitting ratios together with high bandwidth ...

The HFX architecture for local access

2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004
Traditionally telecom copper based loop networks were optimized for voice and cable networks were optimized for broadcast video. As telecom and cable networks evolve both are being upgraded to support voice, video and data services. As the service layer for both networks converge there is an increasing similarity in the physical architecture of both ...

Access control for the services oriented architecture

Proceedings of the 2007 ACM workshop on Secure web services, 2007
Federated Identity Management (FIdM) is being applied to Services Oriented Architecture (SOA) deployments that cross enterprise boundaries. Though federation is essential in order to address the distributed nature of SOA, these FIdM solutions have been found to be inflexible, unscalable, and difficult to use, manage, and upgrade.

An architecture for efficient Lisp list access

ACM SIGARCH Computer Architecture News, 1986
In this paper, we present a Lisp machine architecture that supports efficient list manipulation. This Lisp architecture is organized as two processing units: a List Processor (LP), that performs all list related operations and manages the list memory, and an Evaluation Processor (EP), that maintains the addressing and control environment.

Architecture for Personal Web Accessibility

2006
Universal web accessibility is an inalienable objective to guarantee the civil right of all users to access to the Information Society and to avoid the digital gap. This is a long process based on the promulgation of inclusive laws, specification of accessibility guidelines, and development of adequate design methodologies and tools. To the short term,

Architecture for a Web-accessible simulation environment

Computer, 1997
Despite the dynamic and interactive nature of the language underlying applets, the typical applet still performs a fixed set of operations. Users cannot easily reconfigure such a system to perform "what if" experiments or gather statistical or timing information for an experiment.
