WebRTC is live. Flash, take cover!
Update 2: To the hundreds/thousands of repetitive spam tweets / twits, "Will WebRTC replace / kill Skype", the answer is NO!! It will not. WebRTC is using broken Jingle in the browser, it does not support chat and can only make and receive calls., there is no buddy / contact list to speak of etc etc. NO it will not replace Skype. Stop with the spam tweets already, please!
Update: It seems to me that until all the browsers are on board, native clients will be required to make this go. Which is not outside the realm of possibility, considering Google has open sourced the GIPS audio and video engine along with WebRTC.
Something to remember, WebRTC is not RTCWEB! It may sound silly but it's true. WebRTC is a Google-centric project using Google code etc. RTCWEB is essentially an IETF effort, a working group driving towards open real-time communications on the web. They are not the same, which can be rather confusing.
--- Original Post ---
Google has been busy it would seem, last night WebRTC appeared to the public for the first time. This has some pretty serious implications for Flash, which was the de-facto technology one had to use to get real-time communications in a browser, that has now been circumvented, at least to a certain degree.
The sessions are not run by a signaling protocol per se, not Jingle, no XMPP, not SIP not anything we have seen before. All the session management looks to be coming from libjingle. Which, to me means Jingle is in the browser.
A few early comments:
1. Where does Google stand on websockets? Google have said they will block it if an exploit emerges.
2. Chrome, Opera & Firefox are the supported browsers. Where does Safari and IE land? My guess is that Microsoft will not be in any hurry to implement this considering their recent Skype acquisition.
3. Web-cam captures from HTM5 has not been ratified, although this is likely not as serious as the former points.
So it begins. Skype for Asterisk falls.
It looks like the first victim in the Microsoft acquisition of Skype is Digium and the open source PBX - Asterisk. The following is an email sent to existing Skype for Asterisk users...
Skype for Asterisk will not be available for sale or activation after July 26, 2011. Skype for Asterisk was developed by Digium in cooperation with Skype. It includes proprietary software from Skype that allows Asterisk to join the Skype network as a native client. Skype has decided not to renew the agreement that permits us to package this proprietary software. Therefore Skype for Asterisk sales and activations will cease on July 26, 2011. This change should not affect any existing users of Skype for Asterisk. Representatives of Skype have assured us that they will continue to support and maintain the Skype for Asterisk software for a period of two years thereafter, as specified in the agreement with Digium. We expect that users of Skype for Asterisk will be able to continue using their Asterisk systems on the Skype network until at least July 26, 2013. Skype may extend this at their discretion. Skype for Asterisk remains for sale and activation until July 26, 2011. Please complete any purchases and activations before that date. Thank you for your business. Digium Product ManagementOne has to wonder what will become of Skype Connect, Skype's answer to SIP Trunking. Will Microsoft shut off the Skype Connect vendors (Cisco, Avaya, Grandstream, etc.) as well? Original forum post here.
IETF 80 – RTCWEB BOF
The RTCWEB Bof meeting starts in less than 5 minutes. To some, the most anticipated meeting of IETF 80.
Proposed charter (truncated)...
The WG will perform the following work:
1. Define the communication model in detail, including how session management is to occur within the model.
2. Define a security model that describes the security goals and how the communication model can achieve these goals.
3. Define how NAT and Firewall traversal is to occur.
4. Define which RTP functions and extensions that shall be supported in the client and their usage for real-time media, including media adaptation to ensure congestion safe usage.
5. Define what functionalities in the solution, such as media codecs, security algorithms, etc., that can be extended and how the extensibility mechanisms works.
6. Define a set of media formats that must or should be supported by a client to improve interoperability.
7. Define how non RTP datagram and byte stream data communication between the clients can be done securely and in a congestion safe way.
8. Provide W3C input for the APIs that comes from the communication model and the selected components and protocols that are part of the solution.
