Works are underway inside research community, but their main focuses on Quality of Service, failure recovery, scalability, reliable connectivity, resource utilization and traffic monitoring put security in isolation. As developed initially for a shared link communication, Ethernet lacks security feature. Standardized Media Access Control security (MACsec) provides segment-based security. Its link-constrained feature is constructed mainly for scalability, key-agreement simplicity and traffic analysis, but unsupported multi-segment confidentiality and integrity make the MACsec vulnerable and disqualify it for large Ethernet deployment where switches reside outside of secure premises. In this paper we pinpoint vulnerabilities remained in existing mechanism, and further classify security requirements for unicast and multicast frames. Moreover, we present arguments to support our classification and propose new security approaches using existing Ethernet-based protocols. Finally, we evaluate the performance of our secure data transmission.","PeriodicalId":201451,"journal":{"name":"2010 17th IEEE Workshop on Local & Metropolitan Area Networks (LANMAN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125777742","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 data rates and the processing demands vary over time for many such applications, making the on-demand cloud paradigm a good match for their needs. However, today's cloud platforms need to evolve to meet the storage, communication, and processing demands of data-intensive applications.

This deployment will eventually replace traditional private-line services provided by legacy Time Division Multiplexing (TDM) technologies (such as Digital Cross-Connect Systems and SONET rings) with metro Ethernet services. A critical near-term need is the enabling of rich wireless data applications and, thus, begins a massive upgrade of backhaul links from cellular base stations to their Mobile Telephone Switching Offices (MTSOs), where the various voice and data applications will be provided. These base stations are evolving to 3G/4G technology and require metro Ethernet transport and at significantly higher backhaul technology than the prevalent TDM DS1s (1.5 Mb/s). In this paper, we describe a methodology to enable the rapid introduction of metro Ethernet networks, which includes architecture planning, switch location selection, link placement and sizing, as well as customization for cellular network reliability. Our approach uses a combination of many optimization algorithms and has been integrated into a pragmatic tool used by AT&T network planners. Case studies in very large US metro areas have shown that the tool gives cost-ffective solutions consistent with planner expectations and intuition.","PeriodicalId":201451,"journal":{"name":"2010 17th IEEE Workshop on Local & Metropolitan Area Networks (LANMAN)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114584318","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 paper investigates a protocol that can be efficiently supported across mobile networks and between domains of enterprises. Specifically, we propose a compact presence vocabulary that uses HTTP and SMS protocols to publish to a presence server in the network. The proposed architecture extends the current standardization efforts in OMA PAL working group for non-SIP enabled mobiles.

In contrast to the TCP/IP protocol stack which is based upon the assumption of reliable end-to-end path through the network, the CNF architecture considers varying access link speed/quality and periods of disconnection as inherent properties of the network. Routers in a CNF network are built with large memory space for in-network caching and temporary storage to support transient disconnections due to mobility or link quality variation. Content delivery through the network follows a hop-by-hop transport method in which files move as single entities from one router to the next rather than as end-to-end packet streams. A novel storage aware routing protocol (STAR) is proposed to efficiently support mobile and wireless end-users through the use of a two-dimensional metric that takes into account both short-term and long-term path quality in making forwarding and storage decisions. A reliable link layer provides per hop file transfer reliability. This paper provides an outline of the three basic protocol components of CNF i.e., transport, routing and link layers and describes a proof-of-concept implementation of the protocol stack on the ORBIT testbed. Performance evaluation results in multi-hop wireless scenarios with lossy link conditions show 66% improvement in wireless network throughput compared to TCP and 60% lower packet loss rate when compared to UDP.","PeriodicalId":201451,"journal":{"name":"2010 17th IEEE Workshop on Local & Metropolitan Area Networks (LANMAN)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115868880","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}

An important component of such a network is the interference map, which quantifies the level of interference between pairs of links in the network. Past work in this domain has been relatively sparse, although many protocols and algorithms have been proposed which assume an interference map. In a TDMA network where carrier-sense is disabled, all interference shows up as hidden-terminal cases. Prior work on building interference maps has not focused on the hidden terminal case. Further, most prior evaluation has been in indoor settings. In this work, we present an SIR based interference measurement technique. We start by measuring the average RSS for each link in the network. This is subsequently used to get an estimated average SIR. The average SIR is then used in conjunction with an SIR-versus-PER plot, to estimate the link error rate under interference. We show through measurements on an outdoor 802.11b/g testbed, that the above estimate is accurate for (1) non-interfering links, as well as (2) fully interfering links, but is less accurate for (3) intermediate link pairs. The resultant 3-way classification of inter-link interference will be useful input for subsequent TDMA scheduling algorithms.","PeriodicalId":201451,"journal":{"name":"2010 17th IEEE Workshop on Local & Metropolitan Area Networks (LANMAN)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125682273","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}

In DETS, sending machines monitor and regulate their transmission rates to conform to target rates. The DETS system is implemented in the host system, and there is no need to change or modify any processing or networking hardware. We describe an implementation on a Linux-based cluster, and through experimental performance evaluations, we show that DETS can guarantee the access rate of virtual machines.
