Problems with World-Wide Networking
Holly Brackett Pease, Digital Isle
Administering a worldwide network presents unique routing and logistics problems. Routing policies set by some country's Internet exchanges, by Tier-1 ISPs, and by in-country providers can sometimes be arbitrary and impossible to predict. In this talk Holly will discuss these policies and offer suggestions for navigating them. She will also cover some less-than-glamorous logistics problems presented by the nature of a global network such as: government carriers, interface standards, and taxes.
The Little NIC That Could
Christopher J. Wargaski, RMS Business Systems
Usually the creation and operation of a Network Information Center (NIC) is a costly endeavor requiring vast personnel and equipment resources. This can be a difficult task, especially in a large politically charged environment undertaking cost-cutting measures. Using another model, however, a NIC can be created and run in an efficient manner using only a modest amount of new hardware and software resources, and without additional personnel resources.
10:30am - 11:00am
11:00am - 12:30pm
Splitting IP Networks: The 1999 Update
Thomas Limoncelli, Lucent Technologies
Thomas Limoncelli will discuss techniques for renumbering and splitting IP networks. These techniques were perfected when splitting AT&T's Bell Labs networks in Holmdel, NJ during the AT&T/Lucent split. Renumbering isn't fun, but it is more common every day. He will focus on their trials and tribulations but emphasize techniques that can be used anywhere. Find out what has been learned since the original presentation at LISA '97.
Network Management on the Cheap
Rob Wargaski, RMS Business Systems
This presentation discusses the need and utility of a network management system, and recognizes that many organizations are not willing (for a variety of reasons) to invest in one of the "big" systems. Useful tools can be freely obtained, and run on a Linux system. Rob will describe some tactical and strategic tools and show how they can be used to improve the health of a network.
12:30pm - 2:00pm
2:00pm - 3:30pm
Evolution of VLAN/ELAN Architecture at Vanderbilt University
John Brassil, Vanderbilt University
John Brassil will examine the design and implementation of VLAN architecture at Vanderbilt University that began as part of the Backbone Reengineering Project (1995-98) and the subsequent changes to that design. Since the backbone is ATM-based and edge networks are Ethernet LANs, the parallel Emulated LAN (ELAN) architecture and its evolution will also be described.
The talk is intended primarily as a case study of VLAN/ELAN implementation in a large university or corporate environment. It will describe the factors which influence design decisions, and the tradeoffs/pitfalls that accompany a particular choice. Design considerations for an MPOA (Multi-Protocol Over ATM) architecture will also be discussed.
Interoperable Virtual Private Networks (VPNs), Directory Services, and Security
Eric Greenberg, Seine Dynamics
In order to achieve an organization's network application performance and functional objectives, and make for more manageable and effective deployments, an integrated "Network Application Framework" design approach must be taken. Eric Greenberg will address key areas of framework integration: Virtual Private Networks (VPN) including IPSEC, PPTP, and L2TP; Directory Services including LDAP, NDS, and X.500; Single sign-on and network/application security services including Certificates, Kerberos, and SSL/TLS; and integration of disparate networking architectures including TCP/IP, IBM SNA, and NetWare.
3:30pm - 4:00pm
4:00pm - 5:30pm
Evi Nemeth, University of Colorado, Boulder; k. claffy, Cooperative Association for Internet Data Analysis at the San Diego Supercomputer Center, UCSD
MCI and CAIDA (Cooperative Association for Internet Data Analysis) have dedicated passive measurement boxes (OXcMONS's) on the MCI backbone and at key exchange points. This talk will summarize the data seen on these networks including protocol distributions, packet sizes, flow characteristics, network and AS matrices, etc. We will also present data from an active measurement tool, skitter, that has been used to probe the Internet at about 30,000 key server hosts. Attendees will get a feel for the traffic on the Internet and changes in that traffic over the last couple of years.
