Crossbow Sigcomm09 papers are now online

Crossbow Sigcomm09 papers are now online

Here are the details of the two Crossbow ACM Sigcomm09 papers
  • Crossbow: From Hardware Virtualized NICs to Virtualized Networks Abstract: This paper describes a new architecture for achieving network virtualization using virtual NICs (VNICs) as the building blocks. The VNICs can be associated with dedicated and independent hardware lanes that consist of dedicated NIC and kernel resources. Hardware lanes support dynamic polling, which enables the fair sharing of bandwidth with no performance penalty. VNICs ensure full separation of traffic for virtual machines within the host. A collection of VNICs on one or more physical machines can be connected to create a Virtual Wire by assigning them a common attribute such as a VLAN tag. The full paper is available here
  • Crossbow: A vertically integrated QoS stack Abstract: This paper describes a new architecture which addresses Quality of Service (QoS) by creating unique flows for applications, services, or subnets. A flow is a dedicated and independent path from the NIC hardware to the socket layer in which the QoS layer is integrated into the protocol stack instead of being implemented as a separate layer. Each flow has dedicated hardware and software resources allowing applications to meet their specified quality of service within the host.
    The architecture efficiently copes with Distributed Denial of Service (DDoS) attacks by creating zero or limited bandwidth flows for the attacking traffic. The unwanted packets can be dropped by the NIC hardware itself at no cost.
    A collection of flows on more than one host can be assigned the same Differentiated Services Code Point (DSCP) label which forms a path dedicated to a service across the enterprise network and enables end-to-end QoS within the data center. The full paper is available here

Crossbow Research papers in SIGCOMM, Party, Community One/Java One etc

Crossbow Research papers in SIGCOMM, Community One/Java One etc

Last week was a very exciting week. Two of our research papers got accepted in SIGCOMM VISA09 and SIGCOMM WREN09. This year, SIGCOMM will to be held in Barcelona, Spain from August 17-21 and has four focus areas. Two of them are on Virtualization and Enterprise Networking which is where we had submitted a paper on the virtualization and flows respectively. We will make these papers available online very soon once we submit the camera ready copy to the ACM editors.

So comes the next question - where is the party? Well the party is during the Java One and Community One on June 1 and 2. Did I tell you that Community One is FREE and there is a big party in the evening. I think Crossbow gets formally announced as part of Community One itself and we will have a talk on Crossbow titled Open Networking with Crossbow on June 1st at 2.40pm and a BOF on Crossbow on June 2nd at 5.30pm. We will also be hosting a Demo Pod during Java One.

Crossbow is a more visible initiative but the last few months were pretty fruitful since not only we delivered Crossbow, but also several parts of Clearview and Volo amongst others.

So please come by, help if you can or just enjoy the sessions and enrich yourself and just celebrate. Let me know if you are able to help out in demo, manning the booths and answering questions.
