Data center TCP (DCTCP)
Computer Communication Review - Tập 40 Số 4 - Trang 63-74 - 2010
Mohammad Alizadeh, Albert Greenberg, David A. Maltz, Jitendra Padhye, Parveen Patel, Balaji Prabhakar, Sudipta Sengupta, Murari Sridharan
Cloud data centers host diverse applications, mixing workloads that require small predictable latency with others requiring large sustained throughput. In this environment, today's state-of-the-art TCP protocol falls short. We present measurements of a 6000 server production cluster and reveal impairments that lead to high application latencies, rooted in TCP's demands on the limited buffe...... hiện toàn bộ
Rethinking virtual network embedding
Computer Communication Review - Tập 38 Số 2 - Trang 17-29 - 2008
Minlan Yu, Yung Yi, Jennifer Rexford, Mung Chiang
Network virtualization is a powerful way to run multiple architectures or experiments simultaneously on a shared infrastructure. However, making efficient use of the underlying resources requires effective techniques for virtual network embedding--mapping each virtual network to specific nodes and links in the substrate network. Since the general embedding problem is computationally intrac...... hiện toàn bộ
Virtual network embedding through topology-aware node ranking
Computer Communication Review - Tập 41 Số 2 - Trang 38-47 - 2011
Xiang Cheng, Sen Su, Zhongbao Zhang, Hanchi Wang, Fangchun Yang, Yan Luo, Jie Wang
Virtualizing and sharing networked resources have become a growing trend that reshapes the computing and networking architectures. Embedding multiple virtual networks (VNs) on a shared substrate is a challenging problem on cloud computing platforms and large-scale sliceable network testbeds. In this paper we apply the Markov Random Walk (RW) model to rank a network node based on its resour...... hiện toàn bộ
On-demand time-decaying bloom filters for telemarketer detection
Computer Communication Review - Tập 41 Số 5 - Trang 5-12 - 2011
Giuseppe Bianchi, Nico d’Heureuse, Saverio Niccolini
Several traffic monitoring applications may benefit from the availability of efficient mechanisms for approximately tracking smoothed time averages rather than raw counts. This paper provides two contributions in this direction. First, our analysis of Time-decaying Bloom filters, formerly proposed data structures devised to perform approximate Exponentially Weighted Moving Averages on stre...... hiện toàn bộ
Guidelines for interdomain traffic engineering
Computer Communication Review - Tập 33 Số 5 - Trang 19-30 - 2003
Nick Feamster, Jay Borkenhagen, Jennifer Rexford
Network operators must have control over the flow of traffic into, out of, and across their networks. However, the Border Gateway Protocol (BGP) does not facilitate common traffic engineering tasks, such as balancing load across multiple links to a neighboring AS or directing traffic to a different neighbor. Solving these problems is difficult because the number of possible ch...... hiện toàn bộ
Understanding data center traffic characteristics
Computer Communication Review - Tập 40 Số 1 - Trang 92-99 - 2010
Theophilus Benson, Ashok Anand, Aditya Akella, Ming Zhang
As data centers become more and more central in Internet communications, both research and operations communities have begun to explore how to better design and manage them. In this paper, we present a preliminary empirical study of end-to-end traffic patterns in data center networks that can inform and help evaluate research and operational approaches. We analyze SNMP logs collected at 19...... hiện toàn bộ
Routing in a delay tolerant network
Computer Communication Review - Tập 34 Số 4 - Trang 145-158 - 2004
Sushant Jain, Kevin Fall, Rabin Patra
We formulate the delay-tolerant networking routing problem, where messages are to be moved end-to-end across a connectivity graph that is time-varying but whose dynamics may be known in advance. The problem has the added constraints of finite buffers at each node and the general property that no contemporaneous end-to-end path may ever exist. This situation limits the applicability of trad...... hiện toàn bộ
PAMAS—power aware multi-access protocol with signalling for ad hoc networks
Computer Communication Review - Tập 28 Số 3 - Trang 5-26 - 1998
Suresh Singh, C.S. Raghavendra
In this paper we develop a new multiaccess protocol for ad hoc radio networks. The protocol is based on the original MACA protocol with the adition of a separate signalling channel. The unique feature of our protocol is that it conserves battery power at nodes by intelligently powering off nodes that are not actively transmitting or receiving packets. The manner in which nodes power themse...... hiện toàn bộ
Aggregation and conformance in differentiated service networks
Computer Communication Review - Tập 31 Số 1 - Trang 21-32 - 2001
R. Guérin, Vicent Pla
The Differentiated Service (Diff-Serv) architecture [1] advocates a model based on different “granularity” at network edges and within the network. In particular, core routers are only required to act on a few aggregates that are meant to offer a pre-defined set of service levels. The use of aggregation raises a number of que...... hiện toàn bộ
Towards a Context-Aware Forwarding Plane in Named Data Networking supporting QoS
Computer Communication Review - Tập 47 Số 1 - Trang 4-14 - 2017
Daniel Posch, Benjamin Rainer, Hermann Hellwagner
The emergence of Information-Centric Networking~(ICN) provides considerable opportunities for context-aware data distribution in the network's forwarding plane. While packet forwarding in classical IP-based networks is basically predetermined by routing, ICN foresees an adaptive forwarding plane considering the requirements of network applications. As research in this area is still at an e...... hiện toàn bộ
