httpteleport

Teleports 10Gbps http traffic over 1Gbps networks. Built on top of 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, httpteleport responses may be sent out-of-order. This resolves head of line blocking issue.

  • 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?

    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- based API instead of standard 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:
