In this study, a \"trusted mail gateway\" aiming at reliable and trusted end-to-end e-mail delivery is presented. The designed trusted mail gateway provides a domain with the basic security services that are message integrity, confidentiality, non-repudiation, origin authentication and availability while the message (e-mail) is being delivered through the Internet. It generates S/MIME digital signatures and performs S/MIME encryption on behalf of the domain using secret key cryptography and public-key techniques and generating cryptographic message syntax (CMS) data to provide origin authenticity, integrity and confidentiality. It applies anti-virus control and protection, spam filtering and content check to both incoming mails to the domain and outgoing mails from the domain to prevent attacks against availability. Trusted mail gateway also provides intra-domain security. It keeps e-mail messages in corresponding mailboxes as encrypted messages. Trusted mail gateway processes all the mails passing through and records processing results in a database as notary information. Moreover, it establishes trust relations with other registered trusted domains and exchanges notary information with them via a secure channel","PeriodicalId":304528,"journal":{"name":"2006 International Symposium on Computer Networks","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129518564","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}

The classification of optical burst switched networks (OBS) which is one of the WDM schemes is proposed. We compare the performance of different traffic models on definite signaling protocols of OBS. These traffic models are IP/burst and multimedia traffic. As multimedia traffic we evaluate the performance of video traffic through all-optical network. We also investigate the affects of other traffics and network characteristics on application performance. The examined signaling protocols are JIT, JET and Horizon. We apply the exponential and hyperexponential distributions on these traffics for producing the inter-arrival times of the packets. We present a communication between a source client node and a destination client node over an ingress and one or more multiple intermediate switches. Our paper also includes burst setup, burst setup ack and keepalive message types. We propose a framework for calculating the dropping rates. As a result, we compare the signaling protocols according to the burst drop rates","PeriodicalId":304528,"journal":{"name":"2006 International Symposium on Computer Networks","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124377955","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}

SINR is employed as the criterion for user admission by comparing the SINR with a threshold value (SINR<sub>th</sub>). A small threshold level is desirable to reduce the blocking rate. However, a lower bound of SINR<sub>th</sub> is essential to keep the outage probability (P<sub>out</sub>) below a maximum value. A lower bound of SINR<sub>th</sub> (SINR<sub>th-lb</sub>) has been derived in M.H. Ahmed and H. Yanikomeroglu, (2005) by finding the relationship between P<sub>out</sub> and SINR<sub>th</sub>. Then, SINR<sub>th-lb</sub> is determined as the lowest SINR<sub>th</sub> that keeps P<sub>out</sub> below a certain P<sub>out_max</sub>. In this paper, we improve the accuracy of SINR<sub>th-lb</sub> by modeling the admitted traffic using a Markov model (instead of the inaccurate Poisson model used in M.H. Ahmed and H. Yanikomeroglu, (2005)). In addition, we improve the accuracy by choosing the transition value of the step function that approximates the conditional outage probability distribution using the minimum mean square error criterion","PeriodicalId":304528,"journal":{"name":"2006 International Symposium on Computer Networks","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131372554","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}

As the downlink bandwidth increases, it becomes critical for these applications to have efficient on-demand scheduling mechanisms to increase the number of users that can be supported for dynamically changing workloads. Meanwhile some emerging applications impose deadlines to complete the broadcast service. In this paper, we consider a time-critical wireless broadcast dissemination approach to meet user specific deadlines. We describe a deadline-aware algorithm, called the multiple attributes integration (MAI), to schedule on-demand requests based on a number of attributes.

This bus is widely used in modern real-time distributed embedded systems. Static scheduling strategy is typically used to build a schedule of data exchanges over this bus. We present heuristic algorithms developed to perform the scheduling with optimization of bus load and number of scheduled exchange commands. During the integration phase of the embedded system development, it is often the case that a correct data exchange schedule cannot be constructed due to excessive requirements to communication through the bus.

The performance analysis considers five resource reservation protocols, just-in-time (JIT), JumpStart, JIT+ , just-enough-time (JET) and Horizon, and focuses on the following topologies: degree-four chordal rings, mesh-torus, and the European optical network (EON). Among those topologies, D4T(1,19,3,9) leads to the best performance, while the worst performance is observed for EON. It is shown that the burst loss probability increases with the increase of the control packet processing time. It is also shown that values of OXC configuration time smaller than 1 ms does not have impact on the network performance, independently of the network topology or the resource reservation protocol. Moreover, the performance of the five protocols is very similar for the topologies under study","PeriodicalId":304528,"journal":{"name":"2006 International Symposium on Computer Networks","volume":"33 1-2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116722838","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 self-organization, however, comes at a cost of additional energy consumption of the sensor nodes with already limited power resources. Energy limitations of sensor nodes in unattended environments require a trade-off between power consumption and topology maintenance. In this paper we present our adaptive online scheduling (AOS) protocol that exploits application based data flow characteristics to reduce power consumption during self-organization. Data flow characteristics is used to govern route selection, and to formulate a collision-free transmission schedule that enables risk-free sleeping time.
