There is currently no public document that explains how international networks can connect to GENI. This document explains US R/E networks providing GENI connectivity and how to connect to them and ultimately to GENI. Important things to know when connecting to -
Pac.C: a Unified Control Architecture for Packet and Circuit Network Convergence
PAC.C: A UNIFIED CONTROL ARCHITECTURE FOR PACKET AND CIRCUIT NETWORK CONVERGENCE A DISSERTATION SUBMITTED TO THE DEPARTMENT OF ELECTRICAL ENGINEERING AND THE COMMITTEE ON GRADUATE STUDIES OF STANFORD UNIVERSITY IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY Saurav Das June 2012 © Copyright by Saurav Das 2012 All Rights Reserved ii To my parents iv Abstract Service providers today face several challenges. By all accounts Internet traffic is growing at 40-50% per year, necessitating costly upgrades to carrier infrastructure. Yet carriers do not see a commensurate increase in revenue, nor do they see relative reductions in capital and operational expenditures (Capex and Opex). Part of the problem is that service providers today separately own and operate two distinct networks: packet-switched IP/MPLS networks and circuit-switched TDM/WDM Transport networks. These networks are typically planned, designed and managed by separate divisions even within the same organization, leading to substantial management overhead, functionality/resource duplication, and increased Capex/Opex. This is clearly an expensive and inefficient way to run networks. There have been other attempts to unify the control and management of circuit and packet switched networks – essentially run one converged network instead of two – but none have taken hold. In this thesis, we propose a simple way to unify both types of network using an emerging concept called Software Defined Networking (SDN). SDN advocates the separation of data and control planes in networks; where the data-plane can be abstracted and represented to external software-controllers running a Network Operating System (NetOS). All network control functions are implemented as applications on top of the NetOS. -
On Providing Fair Circuit/Virtual-Circuit Networking Services
On Providing Fair Circuit/Virtual-Circuit Networking Services A Dissertation Presented to the faculty of the School of Engineering and Applied Science University of Virginia In Partial Fulfillment of the requirements for the Degree Doctor of Philosophy Computer Engineering by Mark E. McGinley May 2012 ⃝c Copyright by Mark E. McGinley All rights reserved May 2012 Abstract It has become clear that widespread collaboration in the scientific community, which can increas- ingly be characterized by geographically distributed and large-scale projects, requires predictable network service [1]. Predictable network service needed by applications such as large file trans- fers, remote visualization, and remote instrumentation can only be offered on connection-oriented networks. Circuit-switched and virtual-circuit networks offer such connection-oriented services. This dissertation addresses four issues that inhibit wider adoption of connection-oriented ser- vice. From a theoretical perspective, we address reservation systems and queueing systems. An important consideration for a reservation system with multiple classes, as are necessary to provide a level of service matched with a specific use, is fairness. First, we present a novel three-step scheduling algorithm that finds the optimal solution to a multi-class, fairness-considering bin pack- ing problem, and demonstrate how it can be used to ensure fairness in a reservation system. Sec- ond, with many types of reservation systems across different disciplines, we recognize a need for a uniform way to describe reservation systems, and so present a novel general reservation system model (GRSM), and analyze several examples of commonly encountered reservation and queue- ing systems to understand why certain systems belonging to the same category of examples use reservation systems while others use queueing systems. -

Next-Generation Internet Architectures and Protocols
This page intentionally left blank Next-Generation Internet With ever-increasing demands on capacity, quality of service, speed, and reliability, current Internet systems are under strain and under review. Combin- ing contributions from experts in the field, this book captures the most recent and innovative designs, architectures, protocols, and mechanisms that will enable researchers to successfully build the next-generation Internet. Abroad perspec- tive is provided, with topics including innovations at the physical/transmission layer in wired and wireless media, as well as the support for new switching and routing paradigms at the device and subsystem layer. The proposed alternatives to TCP and UDP at the data transport layer for emerging environments are also covered, as are the novel models and theoretical foundations proposed for understanding network complexity. Finally, new approaches for pricing and net- work economics are discussed, making this ideal for students, researchers, and practitioners who need to know about designing, constructing, and operating the next-generation Internet.
