we de ne approximate xed point in fuzzy norm spaces and prove the existence theorems, we also consider approximate pair constructive map- ping and show its relation with approximate fuzzy xed point.

In this paper we propose a Ping – Pong transitions on web applications. The numerical values of parameters in real time situations are not exactly predictable; to overcome this we are using a fuzzy criterion through possibilities which are represented as a triangular fuzzy number. We introduce a method to study the long term behavior (steady state) of Ping – Pong transitions using Fuzzy Markov ...

Security of the "ping-pong" quantum communication protocol recently proposed by Boström and Felbinger [Phys. Rev. Lett. 89, 187902 (2002)]] is analyzed in the case of considerable quantum channel losses. The eavesdropping scheme is presented, which reveals that the ping-pong protocol is not secure for transmission efficiencies lower than 60%. Our scheme induces 50% losses, which, however, can b...

One desirable application of Bidirectional Forwarding Detection (BFD) is to detect a Multiprotocol Label Switching (MPLS) Label Switched Path (LSP) data plane failure. LSP Ping is an existing mechanism for detecting MPLS data plane failures and for verifying the MPLS LSP data plane against the control plane. BFD can be used for the former, but not for the latter. However, the control plane proc...

The Paper evaluates the performance of Bi-directional Shared Tree (BST) multicasting network with two sources and four receivers, attacked by five attackers. These attackers attack the source 1 in network by ICMP Ping Flood. Here we execute the simulation and draw network throughput between source 1 and source 2, queuing transmission delay and drop out data packets at source 1 for ping packet o...

In this paper, the convergence behaviour of linear parallel interference cancellation is investigated. Especially the so-called ping-pong effect where the bit error rate performance is found to oscillate between two different convergence patterns is studied in detail. This effect is shown to be a direct consequence of the extreme eigenvalues of the correlation matrix, allowing for an analytical...

In early January 2001, a new web page was launched. It was named Netscan, and the creators had done quite a bit of work prior to launching their Web site. Actually, the work was quite simple, but time-consuming. They had pinged the entire routed IPv4 address space; or to be more exact, they pinged every IP address ending with .0 or .255. For each PING sent, they expected one PING REPLY in retur...
