Teleports 10Gbps http traffic over 1Gbps networks. Built on top of fastrpc.
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.
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.httptpsource code may be used as an example ofhttpteleportusage.

Q: Why
httpteleportdoesn't use HTTP/2.0?A: Because
http/2.0has many features, which aren't used byhttpteleport. More features complicate the code, make it more error-prone and may slow it down. -
Q: Why does
httpteleportprovide fasthttp- based API instead of standard net/http- based API?A: Because
httpteleportis optimized for speed. So it have to usefasthttpfor http-related stuff to be fast. -
Q: Give me performance numbers.
A:
httpteleportachieves 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:
