shacharzon Route Leak Impacting Cloudflare

Hi Shachar from Peer5 here, we're operating a MultiCDN. Cloudflare is actually one of the best performing CDNs. All CDNs encounter issues small to big - that's why using multiple providers and intelligently routing between them is critical for high resilience.

shacharzon An entrepreneur says 32-hour weeks ‘killed work ethic’ at his startup

I think solving hard problems requires working hard. There are processes that happen while you sleep and dream that I don't know the explanation for, which really help you progress on an extremely difficult problem. In my experience those processes happen only when you're very focused on your problem, it occupies your thought 80% of your waking hours and it's the last thing on your mind before going to sleep.

I remember I saw a video on it from a more credible source than I, but I can't find it.

What really underlines this blog and thread is that as of the moment of writing this comment, there's no official answer from Google, or even a non official one from an employee. The feeling I get as a customer is that they just don't care.

If you're ok with lower resolution then you can lower it, if the service allows it. Obviously remove anything that might use network.

What do you mean exactly by that? You want to replace the contribution side (camera to server) by WebRTC or delivery side (server to screen) or both?

Contribution: there are platforms who already uses WebRTC instead of rtmp to stream the live camera feed. You can use tokbox's apis for example.

Delivery: This is where it gets more tricky, the nice thing about http based streaming like HLS and DASH is that it's cacheable just like any other file served over http - making it extremely scalable and that's how most CDNs operate today. Changing that part into WebRTC has it's benefits like low latency but has a huge degradation in scaling complexity because of the connection state oriented nature of WebRTC, there are companies trying to build that as well e.g: Red5

That's the $1B question. The obvious application is the video conferencing style hangouts, Skype (which are using WebRTC already). The nice thing about having video conf capabilities in the browser is that you can embed it in any web page and start do interesting things with it - like interactive lectures. Improved gaming networking is another vertical. We've built Peer5 (W17) on top of WebRTC to create a P2P CDN for Video streaming

By Web Push you mean http2.0's push feature? If so then yes (http://caniuse.com/#search=http%2F2).

AFAIK Service workers are still under consideration, and nothing was announced.

> I've also seen a bittorrent client that uses WebRTC

Yea, webtorrent[1] is a great project.

We've also created Sharefest[2] a while ago which is basically WeTransfer with no servers.

I think multiplayer web gaming has a nice potential and need for a high performance network stack using WebRTC.

IoT might also be a candidate for direct p2p communication, without the need for all the devices in your home/office to connect directly to the cloud.

shacharzon Launch HN: Peer5 (YC W17) – Serverless CDN

Yes it does, there'll be other parameters but the main goal is to find the nodes that'll help each other the most, and usually that'll be the closest ones. Live streaming is the best use-case, where Peer5 has the most value to give.

Hey, thanks we used three.js for it. We also wrote a blog post about how we built it - https://blog.peer5.com/peer5-live-network/

Indeed Red Swoosh was probably one of the first P2P CDN companies, the main difference from them is the underlying technology - WebRTC enabling a seamless experience for the end user.

CDN is still a very expensive business to bootstrap and most companies in the world rely on Akamai and Akamai like companies.

We provide a few advantages over a traditional CDN: 1. Geographically ubiquitous distribution - wherever there's demand, there's capacity.

2. Improved user experience - since each user can download content both from the existing CDN and multiple other peers it can fetch that content faster and be less exposed to network conditions between it and the CDN's PoP

3. Scale - CDNs as big as they are, even Akamai have a limit, and this pronounces it self the most specifically in live events. Today's biggest live events over the internet has been single digit million concurrent users and they were using several CDNs at the same time. The potential of a P2P CDN is to bring TV scale events to the internet.

Please elaborate how you think it can facilitate a DDoS?

I can't speak to Flickr's use-case specifically, but generally speaking the content delivery market is growing.

shacharzon Launch HN: Peer5 (YC W17) – Serverless CDN

traffic is as localized as possible. As a general rule you can think of, if the peer is more local to you than the nearest CDN PoP you'll receive data from the peer, otherwise you'll receive data from the CDN.

>Cool! Does this mean all peer traffic is local ? Also, how can you detect when traffic is metered ?

We combine both client side and server side methods for that.
