[cisco-voip] Phone tftp client vs ftp client

[Jason Aarons (US)]

I just did a large deployment where we changed loads with Peer Firmware Sharing. On the phone LCD at fetch start you see the ip address it’s getting it from.  Not sure I could tell it was faster as the original network was GigE and all local LAN with tftp local lan.

I’m aware of that, but it’s not really the same thing. BitTorrent transfers itty bitty pieces of the file amongst all peers simultaneously in a completely ad-hoc fashion, whereas Cisco Peer Firmware Sharing transfers the entire file from one peer to another in a hierarchical fashion.

There’s already something similar called Peer Firmware Sharing: http://www.cisco.com/en/US/prod/collateral/voicesw/ps6882/ps6884/white_paper_c11-583891.html

BitTorrent would be an awesome choice of protocol, methinks. The more phones you have, the faster they’d load.

well, considering Connection does directory updates via SMTP, you never know what might happen.

Anything not released is roadmap and under NDA.  I've not heard any ftp discussions but I have heard other transfer protocols discussed.

I wonder if there are any long term plans to switch from tftp to ftp as phone image files keep growing  larger…..seems a phone across a slow wan shouldn’t take 15-20 minutes to upgrade a 9MB image.  I switched to ftp/http for router upgrades years ago as it was almost twice as fast. Wish the phones would change from tftp to ftp or http, etc.

TFTP benefits
  Small footprint client

TFTP limitations
  ACK every packet
  512 byte packet size maximum

FTP benefits
   1500 byte packets
   Scaling windows TCP, etc
   No real drawbacks except client footprint is larger
