And for traffic engineering over MPLS, the key is to select suitable paths to balance the network load to optimize network resource utilization and traffic performance. And from network carriers' point of view, such optimization should be based on their individual networks, service requirements as well as their own administrative policies. In this paper, we present a method to provide the capability to control traffic engineering so that the carriers can define their own strategies for optimizations and apply them to path selection for both QoS routing and dynamic load balancing.","PeriodicalId":197627,"journal":{"name":"2004 IEEE International Workshop on IP Operations and Management","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125389029","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}

Switching based on cell-by-cell scheduling algorithms (fixed-length switching) have been widely studied for years, while a new idea of transferring IP packet based on a packet-by-packet scheduling algorithm (variable-length switching) has been proposed recently. Fixed-length and variable-length switching can be significantly different in performance and implementation complexity. This paper establishes experiments at the aim of evaluating one design issue: whether it should be fixed-length switching or variable-length switching. We investigate various performance measures of interest: bandwidth utilization, packet loss, segmentation and reassembling overhead, as well as average packet latency. The focus of the paper is on identifying key parameters that influence the outcome of this comparison, and on quantifying the potential benefits of each switching mode.","PeriodicalId":197627,"journal":{"name":"2004 IEEE International Workshop on IP Operations and Management","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124768645","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}

It differs from existing switching techniques over DWDM by its superior QoS mechanisms embedded in and its capability to simplify Internet into a single physical-layer user-data transfer platform architecture (SUPA). This paper proposed the extended deficit weighted round robin (EDWRR) algorithm of output scheduling in a multiple-priority queue environment in PFTS nodes. In such nodes, there are multi-ports in a DWDM-based PFTS node and each port contains multi-lambdas. EDWRR guarantees the delay property of real-time traffic and also efficiently transmits non-real-time traffic. The proposed scheduling algorithm is an improvement and extension of deficit weighted round robin (DWRR) algorithm and guarantees the delay property of real-time traffic by adding a frame transmission procedure based on delay priority. Simulations show that EDWRR has better performance than DWRR in QoS provision of real-time traffic.","PeriodicalId":197627,"journal":{"name":"2004 IEEE International Workshop on IP Operations and Management","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122276351","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 advent of the computer networks has accelerated this development, and has sparked the emergence of the numerous environments that enable Web services. However, the computer network security against the distributed denial of service attacks (DDoS) attacks attracts more attentions. The overwhelming alerts generated by the intrusion detection systems make it hard for the security administrator to analyze and extract the attack strategies, which hampers the performance of the attack detection. One method to resolve the problem is the attack scenarios extraction. In this paper, we propose a novel way to correlate the alerts and extract the attack scenarios. The modified case grammar, principal-subordinate consequence tagging case grammar and the alert semantic network, are used to generate the attack classes. Alerts mutual information is also applied to calculate the alert semantic context window size. Afterwards, based on the alert context, the attack instances are extracted.","PeriodicalId":197627,"journal":{"name":"2004 IEEE International Workshop on IP Operations and Management","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130919275","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}

Thus the lifetime of the node is limited by its residual battery energy. Energy efficiency becomes a key issue to be considered in the network self-operating and self-managing process for MANETs. In order to maximize the node lifetime and further to maximize the network lifetime, the energy consumption of the nodes has not only to be minimized but also to be balanced. This paper proposes a new simple and efficient routing, called energy-aware probability routing (EAPR). EAPR introduces a probability model in the DSR (dynamic source routing) route discovery procedure, implicitly balances the communication traffic and further achieves balanced energy consumption among all the nodes in MANETs. We analyze the coefficient /spl alpha/ in the probability model and illustrate its effect on EAPR through simulations. Also simulations illustrate that EAPR outperforms DSR in terms of the balanced energy consumption distribution among the nodes in the network.","PeriodicalId":197627,"journal":{"name":"2004 IEEE International Workshop on IP Operations and Management","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133289862","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}

Resource guaranteed VPNs are static and require complex service level agreements (SLAs), whereas tunnelled VPNs, such as those in use over the Internet, are more lightweight but do not assure quality of service (QoS). In this paper, we propose a programmable tempest framework for class of service (CoS) based resource allocation (CBRA) in multi protocol label switching (MPLS) tunnelled VPNs. Switchlet based resource partitioning concept is used to create, build and provision multiple VPNs on demand. The proposed approach provides overlay control architecture for both intra-and inter-VPN resource allocations. The intra-VPN resource allocation is based on class of service (CoS) arbitration using derived labels and derived switchlets and inter-VPN resource allocation is through bandwidth brokering (BB). We have evaluated the intra-VPN resource allocation and management by enhancing the MPLS label space with CoS based derived labels and initial results are encouraging.","PeriodicalId":197627,"journal":{"name":"2004 IEEE International Workshop on IP Operations and Management","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122368153","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}

One effective means to defend against such attacks is to locate the attack source(s) and to filter out the attack traffic. To locate the attack source(s), this paper proposes an adaptive packet marking scheme for IP traceback, which supports two types of marking. A participating border router would perform deterministic router id marking when a packet enters the network for the first time, and probabilistic domain id marking when it receives a packet from another domain. After collecting sufficient packets, the victim would reconstruct the attack graph incorporating attack paths and the source router(s) identified, with each node on the paths viewed as a domain. Based on the attack graph traced back we propose to let the filtering agent(s) inspect the markings inscribed in the received packets and filter the packets with a marking matching with the attack signatures. Simulation results show that the proposed marking scheme outperforms other IP traceback methods as it requires fewer packets for attack paths reconstruction, and can handle large number of attack sources effectively with relatively low false positives produced. Meanwhile, with the attack packets filtering mechanism, around 80% attack traffic would be removed and the normal traffic can be efficiently preserved in order to restore the victim's service.","PeriodicalId":197627,"journal":{"name":"2004 IEEE International Workshop on IP Operations and Management","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133765548","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}
