For those who might not know (and are still interested in the topic?) ORTC, Object RTC, is an initiative that was started one year ago by a group of people who were not comfortable with the approach taken for the design of the WebRTC APIs. This group recently published the first official draft of an alternative API including support from very relevant people from Google and Microsoft.
Signaling between client end points has always been an important facet for most interactive web applications. The use cases range from text chatting to multiplayer games to driving a robot remotely. In the world of HTML5, most developers establish signaling through websockets, long polling and server side events. However with the advent of WebRTC, data channels joined the ranks and the question posed by many developers is “Where do data channels fit in the equation?”
Data Channels provide a way to send binary / text data to another peer over the browser. The data channel api is very similar to web sockets when it comes to sending different types of data. It works peer to peer without the need of a centralized server or an additional hop in most cases.
When creating new services and products, organizations always face a challenge whether to buy or build key underlying components and functionality. As WebRTC attracts an increasing degree of interest, we regularly hear from customers that they are considering the trade-off around the decision to buy or build. Many go so far as to try and build their own real time video or audio solution before they turn to a hosted platform like OpenTok. Not surprisingly given the business we are in, we come down pretty strongly on the side of leveraging a hosted service.
