An advantage of transparent network is its independence of the bit rate and modulation format. Hence the transition from 10 to 40 Gb/s in a transparent network can be imagined as a gradual replacement of transponders working at 10 Gb/s with transponders at 40 Gb/s and the co-existence of both bit rates. In this paper we propose a routing method optimizing the exploitation of unused capacity in 40 Gb/s channels and also reducing the number of optoelectronic devices; we name this criterion ‘10/40 Gb/s synergy’. We show that routing 10 Gb/s demands at different bit rates is more performing than a routing at a fixed bit rate; we also show that the synergy minimize the number of required 40 Gb/s transponder as a function of traffic characteristics.","PeriodicalId":442274,"journal":{"name":"Networks 2008 - The 13th International Telecommunications Network Strategy and Planning Symposium","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122493157","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 fact that attackers know the intrusion detection algorithm will not help them if there is a secret key for each implementation that makes it different enough from the others. Implementation of network packet payload anomaly detection IDS that enables application of the idea is presented. Results for various keys confirm excellent detection capabilities.

In order to precisely capture the features of practical network operation and improve the accuracy in the availability evaluation, the dependency of network element failures is characterized by failure states (FS). For this purpose, a method that generating a failure state list for protection is developed and embedded in the proposed survivable routing algorithm such that the pre-defined connection availability can be guaranteed as simple as by protecting a single FS failure. Built on the availability evaluation a novel availability-constrained survivable routing algorithm, called Generalized Dedicated Protection (GDP), is introduced for circuit switched mesh networks. The proposed algorithm inherits the simplicity of dedicated protection mechanisms while offering the connection availability guarantee in presence of the network topological limitation that has been taken as the greatest challenge in the related research effort. Finally, extensive simulation is conducted to verify the advantages gained in the proposed GDP method compared with a number of previously reported counterparts.","PeriodicalId":442274,"journal":{"name":"Networks 2008 - The 13th International Telecommunications Network Strategy and Planning Symposium","volume":"260 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114526538","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}

A correct tariff scheme for these products should be correlated with the cost of production. This paper proposes a model based on TELRIC to calculate and distribute the cost of a network element according to the usage that each user type makes of it, based on the services demanded by the user. The cost model is based on the QoS required by different types of service and three traffic engineering methods: over-engineering, separated virtual tunnels and priority queuing, and studies their influence in costing estimation. The cost model is applied as an example to a connection between a DSLAM and a concentrator in order to estimate the influence of the QoS and the traffic engineering mechanisms in the resulting cost.","PeriodicalId":442274,"journal":{"name":"Networks 2008 - The 13th International Telecommunications Network Strategy and Planning Symposium","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124069759","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}

With reference to techniques that rely on better system configuration, in particular, TCP settings, this paper presents a novel mathematical model for understanding SYN flood DoS attacks considering both statistical properties of incoming legitimate and adversarial SYN traffic and, unlike in existing works, Round Trip Time (RTT) of TCP traffic. The approach relies on stochastic simulations for the general case but provides a closed-form solution for the case of incoming SYN traffic conforming to a Poisson process and backlog queues having an infinite capacity.","PeriodicalId":442274,"journal":{"name":"Networks 2008 - The 13th International Telecommunications Network Strategy and Planning Symposium","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126368096","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}

This work, carried out within the VISION project framework, sets the basis for building an ultra-low latency network for a high-quality videoconference system capable to provide a real feeling of presence, including 3D representation. The need of a full-optical transport network to achieve this aim is justified along the paper. The appropriate evolution of the switching techniques from optical circuit switching to optical packet switching is reasoned and the challenges hindering this evolution are stated. At a lower level, the technologies and materials available to perform optical switching, fulfilling the specific requirements, are reviewed. We present initial scalability simulations of electro-optic switches and future research in this field is posed. Finally, in this paper we propose and explain a design of a large optical packet switch employing optical labels.","PeriodicalId":442274,"journal":{"name":"Networks 2008 - The 13th International Telecommunications Network Strategy and Planning Symposium","volume":"Supplement 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131237565","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}

While mean traffic load is well understood and measurable, the appropriate degree of over-provisioning is a matter of guess and sometimes controversial disputes among experts. We show that traffic fluctuations around the mean value— and in consequence the required over-provisioning— are decisively influenced by the end user access capacity. A theoretical analysis of flow inter-arrival time and flow length probability distributions is used to derive a practical dimensioning rule for packet links in aggregation networks (LAN as well as WAN). The theory has been cross checked by real life experiments with real network equipment.","PeriodicalId":442274,"journal":{"name":"Networks 2008 - The 13th International Telecommunications Network Strategy and Planning Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125797764","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}
