  • on the design implementation analysis and prototyping of a 1 μs energy efficient carrier class optical Ethernet Switch router
    Journal of Lightwave Technology, 2014
    Co-Authors: Sarvesh Bidkar, Saurabh Mehta, Rishiraj Singh, Ashwin Gumaste
    Abstract:

    The integration of layer-2 carrier-class packet technologies with optical transport network is termed as packet-optical integration and is being deployed by service providers for migration from legacy SONET/SDH systems. We present a state-of-the-art carrier-class Switch router that facilitates packet-optical integration, thereby achieving best of both the optical and packet worlds. The premise of this Switch router is the use of carrier Ethernet technology as a packet enabler for achieving statistical multiplexing at fine granularities, while maintaining rich operations, administration, maintenance, and provisioning features. To this end, we proposed the omnipresent Ethernet concept that uses binary routing and source routing to support: 1) layer 2 and layer 3 Switching and routing, 2) low latency of the order of 1–5 μs even for layer 3 processing, and 3) low-energy consumption. The omnipresent Ethernet framework leads to a software defined networking solution, whereby a centralized controller admits services and configures nodes based on homogenous networking parameters. In this paper, we report a commercial implementation of a packet-optical network demonstrated by our designed, fabricated, developed carrier Ethernet Switch router (CESR). We discuss the architectural considerations, design, and implementation of both the hardware and the control software. A Switch architecture achieving 1-μs port-to-port delay across layers 1, 2, and 2.5 based on an opportunistic principle of virtual output queuing is showcased. The novelty is a scalable 96-Gbps cross connect fabric implemented in a field programmable gate array using a two-stage buffer system. A multistate software defined control plane is also reported. An exact analysis of the Switch architecture using a combinatorial G/G/1 model is developed. An energy audit of the CESR is showcased. A test bed in the lab replicating a field deployment is presented. An exhaustive set of test cases are developed to test our designed CESR. Results are shown for latency, throughput, service support, frame-size stability, power, and bit error rate, thus validating our design.

  • circuit performance in a packet network demonstrating integrated carrier Ethernet Switch router cesr optical transport network otn
    2013 International Conference on Computing Networking and Communications (ICNC), 2013
    Co-Authors: Sarvesh Bidkar, Saurabh Mehta, Deval Bhamare, Nilesh Bajaj, Abhishek Medhekar, Ashwin Gumaste
    Abstract:

    Circuit Switched systems in the metropolitan and core networks are being steadily replaced by the packet optical integration brought about by the steady advances in Carrier Ethernet, Optical Transport Network (OTN) and Reconfigurable Optical Add-Drop Multiplexer (ROADM). We demonstrate a state-of-the-art Carrier Ethernet Switch Router (CESR) with integrated OTN function as a mechanism to better facilitate packet-optical integration leading to service and layer 2.5 routing support. The design, development of this CESR+OTN platform is described. The test-bed showcases an integrated high-speed optical network configured as an inter-connected ring topology of 16 nodes, multi-degree cross-connects and demonstrates next generation application services used for cloud computing and mobile backhaul. Performance results indicate that the packet optical technology proposed by us and showcased in a live test-bed compare similar to (or in some cases better than) a circuit Switched network.

  • Multiplatform management of a Hard Real-Time Ethernet Switch
    IEEE, 1
    Co-Authors: Pleszko Aleksander, Barraca, João Paulo, Ferreira Joaquim, Gonçalves Pedro
    Abstract:

    The Hard Real-Time Ethernet Switch (HaRTES) allows using the same network to handle multiple traffic flows, without compromising the performance of real-time applications. Furthermore, it also provides flexible and on-line scheduling techniques with admission control capabilities, thus real-time communications flows can be added, removed and updated online with strict temporal isolation. However, HaRTES lacked a standard management interface to configure its parameters and view its status. This paper describes a multiprotocol (SNMP and NETCONF) management interface design, and implementation. It also presents a preliminary validation of the two management technologies

  • a tdma Ethernet Switch for dynamic real time communication
    Field-Programmable Custom Computing Machines, 2010
    Co-Authors: Gonzalo Carvajal, Sebastian Fischmeister
    Abstract:

    A real-time communication medium must provide a special coordination mechanism to guarantee bounded communication delays. Implementing this mechanism in software offers flexibility but reduces reliability and performance. On the other hand, customized hardware solutions deliver high throughput and predictability, but they increase the implementation cost and are unable to adapt to the specific needs of individual applications. In this work, we introduce a Switch that implements a programmable dedicated time-triggered packet Switching mechanism on top of Ethernet. The Switch, called the Network Code Switch bases on the NetFPGA system and executes flexible but verifiable state-based schedules encoded in the Network Code programming language. This permits the user to tailor the communication behavior to the needs of the distributed application with verifiable performance. We discuss our experience starting at the designing to the implementation of the prototype, and describe how we exploited modularity and code reutilization to reduce the implementation costs and increase the flexibility of the architecture. We also validate our design by evaluating the overhead and throughput of the implemented prototype.
