Hi, I also support adding a subsection for P2P proxy use cases. -Ning From: ppsp-bounces@ietf.org [mailto:ppsp-bounces@ietf.org] On Behalf Of Y. Richard Yang Sent: Thursday, July 12, 2012 11:35 PM To: Rui Cruz Cc: ppsp Subject: Re: [ppsp] WG Last Call for draft-ietf-ppsp-problem-statement Hi Yunfei and Rui, The idea of showing a use case of a proxy is good and helpful. One short comment is that I am not sure if it needs two sub sections 5.4/5.5. Maybe a single P2P proxy subsec is enough? Inside the subsec, it can mention multiple instances. Just a short suggestion that you may consider. Thanks!

I also like your Use Case, but I think it deserves to be a new one (5.5 Proxy service for Browser-based HTTP streaming).

I like this use case. I happen to think of one similar one: Plug-ins supporting P2P streaming where plug-ins are often used in browser-based environment and with plug-ins http based streaming can be turned into a de facto P2P streaming( For the users and browsers, it's just http based streaming but the plug-ins are equipped with PPSP can actually accelerate the process from multiple sources/peers. In this case the plug-ins are just like the proxy. Can we merge them together?

The description would be as follows: 5.4. Proxy service supporting P2P streaming For applications where the Peer is not co-located with the Media Player in the same device (e.g. the Peer is located in a Home Media Gateway), we can use a P2P Proxy, as shown in figure 6. As shown in this figure 6, the P2P Proxy terminates the Tracker and Peer protools, allowing the legacy presentation devices to access P2P content. In this figure the DLNA protocol is used to communicate with the presentation devices due to its wide deployement in the industry, but of course other protocols can be used. +----------------------------------------------------------------+ | | | 0:Tracker Protocol +---------+ | | +----------------> | Tracker | | | | +---------+ | | | ^ | | | | | | | 2: | Tracker Protocol | | | | | | | +---------|-------------------------------------| | | | V | | | | +---------+ | | | +----------|---> | P2P |<-------------------+ | | | | | | Proxy | DLNA | | | | |3: Peer | +---------+ Protocol | | | | | Protocol | | | | | | | | | | V V | V | | +-----------+ | Home Domain +------------+ | | | Outward | | | DLNA Pres.| | | | Peer | | | Devices | | | +-----------+ | +------------+ | +----------------------------------------------------------------+ Figure 6 Proxy service Supporting P2P, with DLNA interface, for Home application Regards, Rui Cruz rui.cruz@ieee.org<mailto:rui.cruz@ieee.org> IST/INESC-ID/INOV - Lisbon, Portugal __________________________________________ ppsp mailing list ppsp@ietf.org<mailto:ppsp@ietf.org> https://www.ietf.org/mailman/listinfo/ppsp On 12/07/2012, at 09:46, stefano previdi wrote: All, we're (re)spin the WG last call process for the problem statement and requirements draft.
