RSS relayRelay Attacks on Bluetooth Authentication and Solutions
White Paper This paper describes relay attacks on Bluetooth authentication protocol. The attacker does not need to guess or obtain a common secret known to both victims in order to set up these attacks, merely to relay the information it receives from one... [09 Aug 2005]
Observations of IPv6 Traffic on a 6to4 Relay
White Paper FUNET (Finnish University and Research Network) has been operating a public 6to4 relay since November 2001, advertising the anycast prefixes (2002::/16, 192.88.99.0/24) globally. The packets sent and received by the relay have been logged for the... [14 Mar 2005]
Capacity Theorems for Wireless Relay Channels
White Paper An achievable rate region for memoryless relay networks is developed based on an existing region for Additive White Gaussian Noise (AWGN) channels. It is shown that multi-hopping achieves the information-theoretic capacity of wireless relay... [29 Nov 2006]
Subchannel Assignment in OFDM Relay Nodes
White Paper The paper considers a source-relay-destination link in which the relay node is allowed to reassign the input subchannels to different output subchannels. In particular, the authors consider a channel-aware relay node and compute the subchannel... [11 Apr 2007]
Frame Relay Circuit Management - the Next Generation
White Paper Frame Relay is enjoying rapid growth as the preferred technology for sending corporate data over a WAN. However, even wider adoption of this technology is constrained by the lack of cost-effective, accurate tools for Frame Relay circuit management. [24 Feb 2004]
Cooperative Protocols for Multiple-Source Multiple-Relay Wireless Networks
White Paper This paper studies the cooperative communications in wireless systems with ns source nodes, nr relay nodes, and single destination node. The impact of the detection error at the relay node on the system performance is analyzed, and then a relay... [31 Aug 2007]
SNA Over Frame Relay
White Paper This Technology Guide examines the successful transition of SNA traffic from traditional leased line environments to Frame Relay network services. With mature Frame Relay services, SNA traffic can be managed and Frame Relay networks designed in... [24 Feb 2004]
MPLS, Frame Relay, and Ethernet
White Paper The significance of Frame Relay/Ethernet integration must be understood in economic, not technological, terms. Frame Relay (and by this we mean Frame services backed by ATM aggregation) represents the mainstream of modern business data networking... [22 Nov 2007]
Frame Relay Service in Today's Enterprise Network Environment
White Paper Building on the maturity of the Frame Relay technology, this Guide explores those attributes of a carrier that best meet the needs of the customers in supplying Frame Relay service, including full customer service and Frame Relay service network... [24 Feb 2004]
Converging ATM/Frame Relay Over MPLS - Solving Control Plane Interworking
White Paper The emergence of new standards for Layer 2 transport, new Layer 3 applications, and multiservice interworking over MultiProtocol Label Switching (MPLS) have made MPLS a desirable framework for integrating specialized ATM, Frame Relay, and IP... [05 Jul 2008]
Algorithms for the Spatial Single Relay Channel
White Paper The spatial single relay channel consists of a transmitter, a relay and a receiver located in an environment with distance-dependent path loss as well as scattering. This paper demonstrates the effects of proximity gain and multiplexing gain in... [03 Sep 2007]
Voice over Frame Relay Tech Paper
White Paper This article discusses voice over frame relay (VoFR). Keep in mind that there are other voice over data technology options, such as voice over IP and voice over ATM, that can do many of the same functions as VoFR. [24 Feb 2004]
Developing a Real-Time IP-Based G3 Facsimile Relay Solution
White Paper The company wanted to develop and implement a real-time IP-based G3 facsimile relay and voice solution for a satellite network as well as optimize and implement VoIP codecs, Line Echo Canceller, and the T.38 packetization protocol. [14 Jan 2008]
Information-Theoretic Multi-Hopping for Relay Networks
White Paper Recent advances in multi-hopping are extended to relay networks having multiple antennas and multiple sources. As for the single-antenna and single-source case, one can achieve the ergodic capacity of wireless relay networks with phase fading if... [28 Nov 2006]
From Frame Relay to VPN: Why to Migrate, Why to Out-Task to a Service Provider
White Paper This white paper explains considerations for companies that are evaluating migration from Frame Relay to IP-based VPNs. It compares the two services, discusses the business and technical advantages of migration, and explains the benefits of out... [06 Oct 2005]
