Such applications require the optimization, close integration, and control of all grid resources, including networks. The EnLIGHTened (ENL) computing project has designed an architectural framework that allows grid applications to dynamically request (in-advance or on-demand) any type of grid resource: computers, storage, instruments, and deterministic, high-bandwidth network paths, including lightpaths. Based on application requirements, the ENL middleware communicates with grid resource managers and, when availability is verified, co-allocates all the necessary resources. ENLpsilas domain network manager controls all network resource allocations to dynamically setup and delete dedicated circuits using generalized multiprotocol label switching (GMPLS) control plane signaling. In order to make optimal brokering decisions, the ENL middleware uses near-real-time performance information about grid resources. A prototype of this architectural framework on a national-scale testbed implementation has been used to demonstrate a small number of applications. Based on this, a set of changes for the middleware have been laid out and are being implemented.","PeriodicalId":441667,"journal":{"name":"2007 International Symposium on High Capacity Optical Networks and Enabling Technologies","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121351455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Distributed computing provides us with the facility of autonomy of sites. Multi-agent system (MAS) are also a branch of distributed computing. In a MAS distributed system, agent is able to work with other agents and to make reasoning about the environment in which it is currently working. Agent works on different platform open network i.e. LAN, WAN, Internet, which increases the malicious behavior in the environment. With this open environment one can not trust with surety as there is no one accountable for this misbehavior. There should be some security measures which enhance the security and trust for agent to defend themselves against attack of other agents and humans activities. To promote interoperability among agents there should be some trust between agents to migrate freely and without risk. Providing security services in the open environment is quite challenging and attractive. Agents mainly trust on two main component of FIPA reference model i.e. directory facilitator (DF) & agent management system (AMS). These two components must be enough trust worthy to gain trust of various agents. This research will be based on authentication of agents with DF to provide the secure environment e.g. if agent A register itself with DF, any other Agent B cannot delete or modify the Agent A services or the agent A itself. In future we will be working with AMS authentication. Authentication between application agent & DF uses simple authentication security layer (SASL) protocol includes a series of steps before agent can be authenticated at DF.","PeriodicalId":441667,"journal":{"name":"2007 International Symposium on High Capacity Optical Networks and Enabling Technologies","volume":"344 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115452209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OBS is a technology that takes the best features of packet switching and circuit switching by providing a flexible infrastructure for carrying IP traffic and at the same time ensuring efficient utilization of the fiber link. In this paper we propose an effective contention resolution scheme to achieve minimum burst loss at core nodes. Algorithm of zero burst loss for bimodal burst switching is extended from single node star network topology to two node star topology. Scheduling at the core node, typically an optical cross connect (OXC), is performed in two modes i.e., Mode 0 & Mode 1. Mode 0 is for burst transmission between all directly connected edge nodes whereas Mode 1 is for burst transmission through remote core node to a particular destination edge node. Synchronization of the reservation request between the core nodes is a critical task in such a topology. In order to achieve minimum burst loss, using a small length of fiber delay line in recirculation mode results in an effective strategy.","PeriodicalId":441667,"journal":{"name":"2007 International Symposium on High Capacity Optical Networks and Enabling Technologies","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124276907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such dasiaoptical-wireless networkpsila architectures have potential to support broadband wireless access over 1 Gbps. Developing a cost-effective bi-directional solution that supports uplink and downlink data transmission between Control Station (CS) and Base Stations (BSs) is one of the research issues in RoF. We present a bi-directional RoF solution, where downlink scheme is based on photonic frequency upconversion. SOA-MZI is used to mix IF and LO signals and all-optically up-convert IF signal. Signals in intermediate frequency (IF) band (2.5 GHz) along with LO (37.5 GHz) are generated in CS. IF signals are up-converted to RF (40 GHz) at remote node (RN). An additional un-modulated carrier at 6.5 GHz is sent along with downlink data and is also up-converted to 44 GHz at RN, this is used as a LO for down conversion of uplink data. Uplink down-converts RF signal (36 GHz) to IF (8 GHz) at BS. As downlink optical carrier at output of SOA-MZI is in double side band format, optical carrier is extracted and re-used for uplink data transmission. Down- and up-link radio signals are DPSK modulated at 155 Mbps. In this paper, we present proposed solution and simulation results for uplink and downlink. Signals at BS and CS, for downlink and uplink respectively are de-modulated with acceptable BER, with BER < 10-9. By deploying the proposed system, a cost-effective RoF architecture can be implemented.","PeriodicalId":441667,"journal":{"name":"2007 International Symposium on High Capacity Optical Networks and Enabling Technologies","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128197706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, different research programs have been aiming at lowering such disruptions. In fact, the problem of designing systems with dependability, reliability, or security characteristics has long been acknowledged as an area for further research, and has received a substantial amount of attentions in the last few years by many different organizations and institutes. However, there are various inconsistent concepts and terminologies that are commonly used to describe the performance of systems (e.g., high-confidence, survivable, trustworthy, and robust). Some of these concepts are quantitative while others are qualitative, and it is a challenge to analyze and evaluate the performance of systems subjectively. Therefore, in this research, we are relating the various subjective concepts to a simple measurable concept which is the reliability concept, and based on analyzing this concept in the high-speed IP-based network environment, the reliability concept is further expressed by the quality of service (QoS). A QoS mapping between the lower and upper layers loss rate performance parameter has been developed. Further, the impact of the lower layer packets loss on the upper layer frames quality has been investigated. This mapping allows better understanding of the technical network parameters from the applicationpsilas perspective of the service level agreement (SLA) and it balances the reservations of the right resources.","PeriodicalId":441667,"journal":{"name":"2007 International Symposium on High Capacity Optical Networks and Enabling Technologies","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124625913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spread ALOHA is currently recognised as a simplified wireless multiple access system which provides a higher bandwidth and may accommodate high number of users. Over the last decade, several models have been developed to predict and estimate the performance of Spread ALOHA. Various combinations of protocols have been employed to enhance performance. This paper investigates the employment of a unique spreading code in conjunction with Spread ALOHA as opposed to the common method of employing distinct spreading codes for all users on the communication channel. In this paper we have modeled and simulated a Single Code Spread ALOHA (SCSA) system together with a conventional CDMA ALOHA system in order to analyse and compare the performance of both systems. Two types of PN codes were used in the simulation models, namely m-sequence and Gold codes. The simulation results showed comparable performance of both systems, and verified the suitability of m-sequence for SCSA and Gold codes for CDMA respectively.","PeriodicalId":441667,"journal":{"name":"2007 International Symposium on High Capacity Optical Networks and Enabling Technologies","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127532999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
