SPDY is a one of a kind internet protocol that has been developed by Google that aims to amplify the effectiveness and momentum of delivering all kinds of web content. The SPDY protocol works by modifying some parts of HyperText Transfer Protocol or HTTP for improving web performance. Although HTTP is a powerful protocol in itself, it is not always sufficiently strong enough to keep up with all the current needs and demands of the responsive and dynamic websites that are mostly in use nowadays. Some of the common limitations of HTTP, such as downloading only a single resource at a given time often make it rather difficult to scale and load large websites which also renders it difficult to serve the ever-increasing user base.
The SPDY is a protocol that is intended to be a key to resolving some of the larger issues that users face with HTTP. SPDY helps to optimize the HTTP traffic when it is sent over web or Internet, thus resulting in about 28% to 64% speed enhancement for many of the top websites of the world. The SPDY protocol works together with HTTP simply by modifying the web traffic while it is sent from the server. As soon as a user gets connected to a website, it gives rise to an HTTP session which helps to control the overall flow of information. The SPDY helps to modify the data as it passes through a session, thereby optimizing the bandwidth usage for giving rise to a faster and superior user experience.
What SPDY Protocol Offers?
There are numerous critical problems associated with HTTP web browsing that are resolved by SPDY. Some of them have been discussed in brief.
- Classically HTTP can only send a single request for every connection. The HTTP protocol can fetch only one resource or request at a time, thus leading to underutilized bandwidth and delays. On the other hand, SPDY makes it possible to carry out multiple concurrent downloads.
- HTTP requires a user to send a request for content from the server in order for it to be delivered. However, with SPDY it is possible for the server to “push” the data to a client without actually having to linger for the request, thus making it easily possible for the web content to be loaded before it is required.
- Redundant headers are often a major problem with the HTTP protocol. HTTP headers usually define the nature and behavior of the HTTP transaction. There are instances in which the same headers get repeated during the course of the session. On the other hand, SPDY removes all unnecessary headers and reduces the overall bandwidth that is required.
- Compression helps to shrink the sizes of the data packs during delivery. However, such compression is purely optional for HTTP. With SPDY, there is forced compression for each and every communication including headers.
Why Is SPDY Preferred?
There are a number of reasons why many businesses prefer to use SPDY. Even if SPDY is required to fix this Chrome problem of err_spdy_protocol_error, SPDY is preferred widely since it offers a substantial range of benefits in exchange for relatively small investment. Here are some of the distinct benefits of using SPDY.
- With SPDY, users can enjoy really quicker or prompt loading times along with lesser bandwidth usage. Moreover, the bandwidth is used more intelligently, thereby letting the users to effectively extend the data caps as they experience improved performance.
- The enterprises can benefit from higher customer satisfaction. The web pages tend to load much faster, thus resulting in better user experience.
The enterprises can also benefit significantly from lower bandwidth costs. The SPDY can optimize the traffic before it is sent from the server, which in turn allows the enterprises to use more of their available network without needing to upgrade to new hardware.
