Its not a goodbye...

Leaving Oracle but not Solaris

This is probably one of the most difficult entry I have ever written. I have decided to leave my job at Oracle. Don't have a forward destination yet but I intend to take sometime thinking about it before I take the next step. I am leaving Oracle but I will still be involved with Solaris and OpenSolaris in some form or the other. Having spend 14 years writing million+ lines of code and architecting some of the most complex subsystems, I don't intend to just walk away.

The last 2-3 days have been a very emotional journey for me. I thought I was a very strong willed person but it was amazing how many times I came close to tears when so many people stopped by. All I can say is that I am so grateful that the community feels that I had done something useful (both personally and professionally) for Solaris. The journey has been nothing but wonderful and I will surely miss everyone. But I have learned one thing in last several years - to not say goodbye ever because our paths will cross again!!

Best of luck to everyone in the Solaris community who help it to be the best operating system on the planet and especially to the people who help write it. Keep the flag flying!! With Oracle, Solaris will reach more places ...

I think I will lose access to this site once I leave Sun/Oracle so I will continue writing on my wordpress blog.

Crossbow paper wins best paper award at Usenix LISA09 and BOF schedule

Crossbow paper wins best paper award at Usenix LISA09 and BOF schedule

We had submiited another paper at Usenix LISA 2009 conference at Baltimore, MD which is being held from Nov 3-5, 2009. The paper is title Crossbow Virtual Wire: Network in a Box. Yesterday we were informed that our paper won the Best Paper award for the conference. Woohoo!!

I met many people here at LISA that are already using Crossbow in very interesting ways. I got many requests to hold a BOF while we were here. So I hit our marketing VP for some beer budget (can't have a BOF without drinks) and we are now having a Crossbow and Solaris Networking BOF on Nov 4th, 2009 from 10.30 to 11.30pm in Dover AB conference room. The venue details can be found on usenix LISA site here. So people who are already at the conference on in the general area of Maryland, Virginia, DC, etc, please do come buy. It would be good to attach faces to name and we will have chilled beer. We will also be showing the Virtual Wire Builder kit to build your own virtual network (all available in open source form).

Once again, BOF details are
  • Crossbow & Solaris Networking BOF at Usenix Lisa 2009
  • Place: Marriott Waterfront Hotel, Baltimore. MD.
  • Date: Nov 4th, 2009
  • Time: 10.30-11.30pm
  • Agenda: Virtual Wire Builder kit, Open discussion, Beer

Hope to see you there.

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
Enjoy reading and join us for the talk BOF and party at Community One (see the previous entry) on June 1-2, 2009!!

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.
