Scalable Resilient Overlay Networks Using Destination-Guided Detouring
White Paper The construction of such routing overlays often does not take into account the physical topology of the network which necessitates that all overlay nodes use aggressive online algorithms for end-to-end... [04 Aug 2008]
Routing and Wavelength Assignment in Optical Networks
White Paper Given the physical network structure and the required connections, the RWA problem is to select a suitable path and wavelength among the many possible choices for each connection so that... [18 Jul 2008]
Network-Wide Load Balancing Routing With Performance Guarantees
White Paper An emerging example is a virtual private network path with Quality of Service (QoS) guarantees, or QVPN. The main technical challenge in offering the QVPN service is how to allocate a... [10 Jul 2008]
Continuous Monitoring of Available Bandwidth Over a Network Path
White Paper This paper presents a new method for real-time monitoring of available bandwidth over a network path. This paper has tested the method with good accuracy and agreement, both in simulation and in a... [10 Jul 2008]
Shortcutting IP Flows over Large ATM Networks
White Paper Short-cutting across such large, logically structured ATM networks is a technique to avoid network layer processing as much as possible by maximizing the switched path across the ATM... [03 Jul 2008]
Resilient Routing Using MPLS and ECMP
White Paper Therefore the paper proposes a new approach combining two protocols readily available in every router: The fast local reaction of the Equal-Cost-Multiple-Path extension of OSPF operating on a network... [25 Jun 2008]
Detailed OFDM Modeling in Network Simulation of Mobile Ad Hoc Networks
White Paper This paper first shows that physical layer variables including path loss, shadowing, multipath, Doppler have significant effects on the predicted overall networking performance. In mobile ad hoc... [10 Apr 2008]
TCP Symbiosis: Congestion Control Mechanisms of TCP Based on Lotka-Volterra Competition Model
White Paper The paper changes the window size of a TCP connection in response to information of the physical and available bandwidths of the end-to-end network path. The bandwidth information is... [21 Dec 2007]
Expose Your Intranet Portal to the Outside World in a Secured Manner (Aka. A Secured Inside/Outside Portal)
White Paper This paper introduces the concept and techniques for implementing a secured "Inside/Outside" topology for OracleAS Portal 10g which allows a users access privileges to be determined not only by their identity but also by the... [09 Jun 2007]
The McCue Interview: BACS' IT chief Nick Masterson-Jones
Comment There are lots of new exciting projects coming down the path. So you'd probably be surprised to find it's actually quite a small physical organisation of around 400 people, based out of an anonymous... [14 Sep 2004]
54 Mbps IEEE 802.11 Wireless LAN at 2.4 GHz: Deploying standards-based Wireless LAN solutions
White Paper Customers will choose standards-based, interoperable solutions that will both protect their existing investment while enabling an upgrade path to high performance WLAN connectivity. These two standards are designed to... [25 Feb 2004]
Using Virtual Ports
White Paper You can configure multiple logical ports over one physical path on the platforms listed in Table 2-1 . To configure multiple ports over one path, you create new logical interfaces called... [25 Feb 2004]
Gigabit Ethernet Auto-Negotiation
White Paper This capability helps ensure a smooth migration path from Ethernet to Fast Ethernet and Gigabit Ethernet. Gigabit transceivers at the physical layer (PHY) of the Open Systems Interconnection (OSI) model... [25 Feb 2004]
Security, security, security - the new business mantra?
Comment As technology continues its inexorable path towards the heart of every business, the phrase 'IT security' should become redundant. This illustrates that physical security is just as important as IT... [29 Aug 2000]
