Any other highly isolated admins here share the struggle of managing limited satellite bandwidth and no chance for fiber? I'm looking at you folks: remote islands, northern Canada territories, desert, polar, big boats, aircraft, etc.
Few questions
- Can anyone here claim the fastest SCPC satellite connection here? Geo sat? O3b MEO? HTS beam? Dish size? Band? Transponder BW? Modulation rates? --- how many users?
- For those that have dedicated SCPC satellite connectivity, are your modems at fixed modulation or ACM to maximize bandwidth? For those with ACM, are you doing QoS on the modem or on your routers and using SNMP to poll the modem for current negotiated speeds?
- For those supporting enterprises - are you using WAN optimization (e.g. Cisco/Exinda/Riverbed) or SDWAN to do TCP acceleration/enterprise SSL decryption?
- How happy are your folks with the user experience of high latency and limited bandwidth? how are you limiting bandwidth use? cafe style several GB/day allocations? throttling per client connections? micro flow policing? On site appliance caches for Apple/Netflix/Streaming/etc?
- Any other tips and tricks to maximize SCPC satellite connectivity and ultimately get the best user experience?
- What is your backup circuit? Another satellite and ground station? Inmarsat? Iridium?
The environment I'm supporting does not have the best QoS policy and it basically lets the 25/12 Mbps SCPC circuit (Geo/10m/Ku band/non HTS/non ACM) for 800+ users become underutilized during off peak hours due to not the best QoS design. Our Riverbed Steelheads can probably be optimized to do more SSL decryption on enterprise content and a holistic analysis of more corporate traffic to decrypt through this. For non work hours - I'm finding that there is too much demand for internet and social media usage for WAN optimization to be useful on personal devices.
I'm waiting for the new constellations from Starlink/OneWeb/O3b mPOWER but it can't come soon enough.
