100G and Beyond Workshop: Ultra High Performance Networking in California
Calit2 Auditorium • First floor, Atkinson Hall • UC San Diego • La Jolla, CA
Tuesday, February 26, 2013 · Campus and Lab Strategies Panel · 11:00AM – 12:00PM
University network operations centers support multiple,
conflicting missions.
Network Security or Network Performance: which is more
NOCs typically accountable to university business
divisions and contend with legal and public relations
pressures → security wins always.
NOCs not usually accountable to research groups
(often never communicate with faculty).
University enterprise (e.g. general
purpose/financial/personal) computing:
security > performance
Computational and “Big Data” research:
performance > security
What can we do to ensure efficient scientific data
transfer between universities and national labs?
A network optimized for business is not designed or capable
of supporting data intensive science.
Universities will always need to
support security features that
protect organizational financial
and personnel data.
Solution: create separate data
intensive science network,
external to university enterprise
Design formalized by ESnet,
based on traditional network
DMZ paradigm
Science DMZ: (1) dedicated access to high-performance WAN,
(2) high-performance switching infrastructure (large buffer
memory), (3) dedicated data transfer nodes

Facilitate high-performance data transfer for scientific applications using
Globus Online GridFTP
Alcatel-Lucent OmniSwitch 10K (core device)
Two Alcatel-Lucent OmniSwitch 6900s (satellite devices)
Dedicated and independent 10GE (maybe 40GE) uplink to Internet2 and ESnet
Optimized network for high-volume bulk transfer of scientific datasets
Unencumbered, high-speed access to online scientific applications and data
generated at SDSU
External access to science resources not impacted by regular “enterprise” or
business class Internet traffic
Focus on “BigData” Intensive Science: earthquake rupture and wave
propagation, parallel 3D unified curvilinear coastal ocean modeling, geologic
sequestration simulation of supercritical CO2, large-scale proteomic data,
bioinformatics of gene promoter analysis, microbial metagenomics, and
high-order PSIC methods for simulation of pulse detonation engines
Network performance measurement based on the PerfSONAR framework
InCommon Federation global federated system for identity management and
authentication to DMZ connected hosts and services
Extension of the standard, two channel FTP protocol
Control Channel
◦ Command/Response
◦ Used to establish data channels
◦ Basic file system operations (e.g. mkdir, delete, etc.)
Data channel: Pathway over which file is transferred
Scheduled transfers using command line interface:
$ scp xsede#lonestar4:~/GO/bigdatafile xsede#trestles:~/GO/bigdatafile
$ scp xsede#trestles:~/GO/bigdatafile paolini#sdsu:~/GO/bigdatafile
Science DMZ performance monitoring accomplished using
perfSONAR tool suite
Server side tools run on designated hosts attached to key
End-to-end testing with collaborating perfSONAR sites
Determine one way latencies and packet loss between hosts
using One-Way Active Measurement Protocol (OWAMP)
owping -c 10000 -i .01 remotedmz
Periodic throughput tests to remote Science DMZs using
Bandwidth Test Controller (BWCTL)
Resource allocation and scheduling daemon for regularlyscheduled Iperf tests
bwctl -s remotedmz -P 4 -t 30 -f M -w 4M -S 32
U.S. education and research identity federation service
Provides common framework for trusted shared management
of access to on-line resources
Provide users single sign-on convenience and privacy
protection – Shibboleth Service Provider Federating software
Site admins can delegate responsibility for administering
service provider (SP) metadata to another admin

Current and planned DMZ related research:
Development of new transport layer protocols that use compressed sensing
techniques to perform sparse sampling on streaming petabyte sized datasets
originating from remote CO2 sequestration, curvilinear coastal ocean modeling,
and earthquake rupture and wave propagation simulations
Development of a new Alcatel-Lucent SDN/Application Fluent Network based
protocol for the OS10K that bridges Lustre RDMA traffic between 40GE and FDR
