# httpteleport

Teleports 10Gbps http traffic over 1Gbps networks.

Built on top of [fastrpc](https://github.com/valyala/fastrpc).

# Use cases

`httpteleport` may significantly reduce inter-server network bandwidth overhead

and costs for the following cases:

- RTB servers.

- HTTP-based API servers (aka REST, JSON, JSON-RPC or HTTP-RPC services

  and microservices).

- Reverse proxies.

- Load balancers.

# How does it work?

It just sends batched http requests and responses over a single compressed

connection. This solves the following issues:

- High network bandwidth usage

- High network packets rate

- A lot of open TCP connections

Unlike [http pipelining](https://en.wikipedia.org/wiki/HTTP_pipelining),

`httpteleport` responses may be sent out-of-order.

This resolves [head of line blocking](https://en.wikipedia.org/wiki/Head-of-line_blocking) issue.

# Links

* [Docs](https://godoc.org/github.com/valyala/httpteleport)

* [httptp](https://github.com/valyala/httpteleport/tree/master/cmd/httptp) -

  standalone single-binary reverse proxy and load balancer based

  on `httpteleport`. `httptp` source code may be used as an example

  of `httpteleport` usage.

# FAQ

* Q: Why `httpteleport` doesn't use [HTTP/2.0](https://en.wikipedia.org/wiki/HTTP/2)?

  A: Because `http/2.0` has many features, which aren't used by `httpteleport`.

     More features complicate the code, make it more error-prone and may slow

     it down.

* Q: Why does `httpteleport` provide [fasthttp](https://github.com/valyala/fasthttp)-

     based API instead of standard [net/http](https://golang.org/pkg/net/http/)-

     based API?

  A: Because `httpteleport` is optimized for speed. So it have to use `fasthttp`

     for http-related stuff to be fast.

* Q: Give me performance numbers.

  A: `httpteleport` achieves 200K qps on a single CPU core in end-to-end test,

     where a client sends requests to a local server and the server sends

     responses back to the client:
