This MorningThis Morning Quick intro and Highlights run-down Open format
Open, informal discussion I have some suggested topics Toss out your own
Open discussion? Show-and-tell Tech-to-tech chatter of stuff that works or doesn’t Open forum
Q&A with me or each other? Demos of web/other stuff? Small group/break-out discussion?
Adjourn to somewhere even less formal?

2009 Changes & Highlights
2009 Changes & Highlights
Fewer AOR slots, more POR slots…for now POR has 6 slots with 256kbps, 5 slots in 2010 AOR has 3 slots with 128kbps, 4 slots in 2010?
Wiki up and running still well FAQs, frequencies, calendar, resources,
maintenance reports, etc. More community input would be better Come get an account if you want one
Training class run at SIO in August Do we need another?
Accelerators tested on 2 ships in 2009, fleet purchase made for 2009/2010 install
Atlantic Explorer online with iSCPC connection

AcceleratorsAccelerators Features include:
Protocol tuning for long-fat pipes Compression and caching of packets (TCP & UDP) Better bandwidth control at higher layers (min/max/etc) Auto fragmentation (better VoIP?)
Why bother? More ongoing effective bandwidth for 1-time cost ~20% shore-to-ship, 65%+ ship-to-shore Great for streaming uncompressed data to shore (Real-
time!) Expand 4830 and 4930 units in use
4830s have no disk, are for C-band ships 4930s have disk for web proxy, are for Ku-band ships
Shipped to home institution, install info on the wiki Rolling install…plug it in, Steve will light it up at some
point Configuration maintained on shore Tuning process is a bit touchy
Requires feedback from the ship Get out what you put in
No acceleration on compressed or encrypted data

Connecting without tunnels
Connecting without tunnels Pros:
No tunnel equipment on shore required No extra hop or failure point on shore No need to get Campus IT involved
during setup or troubleshooting May present like other connection
types Flexibility for MobileIP, VPN to campus,
non-HSN footprint migration Cons:
Performance overhead of tunnel/VPN across satellite
Not part of campus network

More Potential TopicsMore Potential Topics Accelerators
Installation, use, policies, tuning process, etc. Wider coverage areas
GE-23, Med, IOR, Alaska, split Ku into AOR/POR? Wiki demo/discussion Tracking issues and DAC/Comtech cable HSN-wide parent web proxy
Elective, could provide shared caching, antivirus/ad filtering, blacklisting, ToS tagging for various URLs/TLDs
Security/firewalls/DoS – Need support from HiSeasNet?
Routing Tunnel alternatives? MobileIP, VPNs, etc.
Bandwidth Upgrades, shared vs. separate
Training Feedback…did it work in the long term? Do we need
more? Policies
What are they? How to enforce them? Should they be the same? Services offered on ships (IM, web, mail, Skype, streamed
data, etc) Who is running what? How does it work? What does Science expect now?
Random feedback / discussion / experiences

GE-23 SatelliteGE-23 Satellite
Wider beam is weaker and requires larger 1.5m antenna No earth station capabilities right now Strange satellite, needs some hardware changes to
shipboard antennas ($2k?) Availability may be reduced now due to KVH use of satellite Low look angle in port and coastal waters

Used quite successfully on Pt Sur (1m dish) in Gulf of Alaska in 2009
No HiSeasNet earth station capabilities right now, would need additional Ku antenna at earth station

DAC Remote PanelDAC Remote Panel
SeaTel has released DacRemotePanel Runs under Windows
across a serial or IP connection to an antenna controller
Provides extra diagnostic plots, debug data dumps, and visibility into the pedestal control unit.
Officially unsupported, but seems to work well
An upgrade to PCDAC (but it doesn’t have the antenna/ship diagram)
