In early 1997, the Internet Engineering Task Force (IETF) established the Multi-protocol Label Switching (MPLS) working group to produce a unified and interoperable multilayer switching standard as each vendor (Cisco Systems, Lucent, and so on) developed a proprietary multilayer switching solution, maintaining the IP control component and label-swapping components in different ways. The majority of these multilayer switching solutions required an ATM transport because they could not operate over mixed media infrastructures, su ....etc

Abstract”
Here describe a software router capable of flexible service composition through plug and play of specialized Java software modules. These Java modules “ previously developed for network simulation in the J-Sim project “ are leveraged for actual deployment on our router through a JSocket class of objects. Our system provides significant software engineering benefits of simplified code development and safe composition/reuse of various router c ....etc

Content distribution networks (CDNs) balance costs and quality in services related to content delivery. Devising an efficient content outsourcing policy is crucial since, based on such policies, CDN providers can provide client-tailored content, improve performance, and result in significant economical gains. Earlier content outsourcing approaches may often prove ineffective since they drive prefetching decisions by assuming knowledge of content popularity statistics, which are not always available and are extremely volatile. This work addresse ....etc

Introduction

The emergence of optical transport systems has dramatically increased the raw capacity of optical networks and has enabled new sophisticated applications. For example, network-based storage, bandwidth leasing, data mirroring, add/drop multiplexing , dense wavelength division multiplexing , optical cross-connect , photonic cross-connect , and multiservice switching platforms are some of the devices that may make up an optical network and are expected to be the main carriers for the growth in data traffic.

ASTN (Automatic Switched Transport Network) allows traffic paths to be set up through a switched network automatically. The term ASTN replaces the term ASON (Automatically Switched Optical Network) and is often used interchangeably with GMPLS (Generalized MPLS). This is not completely correct as GMPLS is a family of protocols, but ASON/ASTN is an optical/transport network architecture. The requirements of the ASON/ASTN architecture can be satisfied using GMPLS protocols developed by the IETF or by GMPLS protocols that have been modified by the ....etc

Generalized Ring Signatures-IEEE TRANSACTIONS ON DEPENDABLE AND SECURE COMPUTING, VOL. 5, NO. 3, -java

Abstract—
The concept of ring signature was first introduced by Rivest et al. in 2001. In a ring signature, instead of revealing the actual
identity of the message signer, it specifies a set of possible signers. The verifier can be convinced that the signature was indeed
generated by one of the ring members; however, the verifier is unable to tell which member actually produced the signature. In this paper,
we first propose a ....etc

ABSTRACT
In IP routing each packet travels from one router to the next, each router makes an independent forwarding decision for that packet. That is each router analyses packet header, and each router runs a network layer routing algorithm. Each router independently chooses a next hop for the packet, based on its analysis and the results of running the routing algorithm.
In conventional IP forwarding a particular router will typically consider two packets to be in the same FEC(forward equivalence class) if there i ....etc

Abstract
Two major factors that limit the throughput inmulti-hop wireless networks are the unreliability of wirelesstransmissions and co-channel interference. One promising techniquethat combats lossy wireless transmissions is opportunisticrouting (OR). OR involves multiple forwarding candidates torelay packets by taking advantage of the broadcast nature andspacial diversity of the wireless medium. Furthermore, recentadvances in multi-radio multi-channel transmission technologyallows more concurrent transmissions in the network, and sh ....etc
