OpenFlow-based switches are a promising technology to achieve isolation in the transport network. However, these lack carrier-grade QoS support. On the contrary, MPLS is a scalable transport network technology with carrier-grade QoS support. It can isolate multiple QoS classes. Still, when accommodating multiple virtual networks with carrier-grade QoS support, we need to now isolate virtual networks in the same QoS class. MPLS lacks programmability to do that. In this paper, we propose a mechanism to isolate virtual networks in the same QoS class, by using OpenFlow in combination with MPLS in order to utilize the merits offered by both technologies. The core of our proposal does not need modification in the architecture from both. In addition, we also present extensions for faster response in the transport network. The evaluation of our proposal on a prototype proves the validity of our scheme as well as its usefulness in future networks.","PeriodicalId":262262,"journal":{"name":"2013 IEEE 2nd International Conference on Cloud Networking (CloudNet)","volume":"268 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122753098","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 promising direction is to exploit multipath communications, yet existing protocols have a so limited scope that performance improvements are often unreachable. Generally, multipathing adds signaling overhead and in certain conditions may in fact decrease throughput due to packet arrival disorder. At the transport layer, the most promising protocol is Multipath TCP (MPTCP), a backward compatible TCP extension allowing to balance the load on several TCP subflows, ideally following different physical paths, to maximize connection throughput. Current implementations create a full mesh between hosts IPs, which can be suboptimal. For situation when at least one end-point network is multihomed, we propose to enhance its subflow creation mechanism so that MPTCP creates an adequate number of subflows considering the underlying path diversity offered by an IP-in-IP mapping protocol, the Location/Identifier Separation Protocol (LISP). We defined and implemented a cross-layer cooperation module between MPTCP and LISP, leading to an improved version of MPTCP we name Augmented MPTCP (A-MPTCP). We evaluated A-MPTCP for a realistic Cloud access use-case scenario involving one multi-homed data-center. Results from a large-scale test bed show us that A-MPTCP can halve the transfer times with the simple addition of one additional LIS-Penabled MPTCP subflow, hence showing promising performance for Cloud communications between multi-homed users and multihomed data-centers.","PeriodicalId":262262,"journal":{"name":"2013 IEEE 2nd International Conference on Cloud Networking (CloudNet)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130790982","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}

Due to the heterogeneity of various jobs, different VMs on the same PM can have different job completion times. Meanwhile, the PMs are also heterogeneous. Therefore, different VM placements have different job completion times. Our objective is to minimize the total job completion time of the input VM requests through a reasonable VM placement schedule. This problem is NP-hard, since it can be reduced to a knapsack problem. We propose an off-line VM placement method through emulated VM migration, while the on-line VM placement is solved by a real VM migration process. The migration algorithm is a heuristic approach, where we place the VM to its best PM directly, as long as it has enough capacity. Otherwise, if the migration constraint is satisfied, we migrate another VM from this PM to accommodate the new VM. Furthermore, we study a hybrid scheme where a batch is employed to accept upcoming VMs for the on-line scenario. Evaluation results prove the high efficiency of our algorithms.","PeriodicalId":262262,"journal":{"name":"2013 IEEE 2nd International Conference on Cloud Networking (CloudNet)","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122934055","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}

By enabling the consolidation of many virtual machines (VMs) in a physical server, virtualization blurs the frontier between networking and system. We have investigated in a previous work the various prices due to virtualization when a packet is moved from one VM to the physical NIC, by focusing on a pure UDP scenario and multiple competing VMs. We estimated how the inter-packet delay moves away from the optimal point as the number of VMs increases. In the present article we report the impact of virtualization over a whole data stream controlled by the TCP protocol. Our findings reveal that the impact of the additional inter-packet delay is negligible on the performance of TCP. Indeed, virtualized systems have similar goodput levels to the ones of natives systems. Moreover, a less expected result show that virtualized systems improve the fairness between flows, even when such flows are streamed from a same VM. The bad consequences of the virtualization concern mainly bugs in the implementation of the networking function, which can potentially introduce spurious retransmissions and information leaks.","PeriodicalId":262262,"journal":{"name":"2013 IEEE 2nd International Conference on Cloud Networking (CloudNet)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122756103","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}
