Bifrost

Bifrost is a grpc-based P2P network library

(In Norse mythology, Bifröst is a burning rainbow bridge that reaches between Midgard and Asgard, the realm of the gods.)

Getting Started with Bifrost

Installation

go get -u github.com/DE-labtory/bifrost

Usage

Server

import (
  "github.com/DE-labtory/bifrost/pb"
	"github.com/DE-labtory/bifrost/server"
)

// connection control
ConnectionStore := bifrost.NewConnectionStore()

// server listen
s := server.New(bifrost.KeyOpts{PriKey: priKey, PubKey: pubKey})
server.Listen(_gRPCatewayIP_)

Client

import (
  "github.com/DE-labtory/bifrost/client"
)
connection, err := client.Dial(command.Address, clientOpt, grpcOpt) //흔히 cli 에서 이루어짐
connection.send(payload []byte, protocol string, successCallBack func(interface{}), errCallBack func(error)) //connection GrpcConnection

Document

process buffer

bifrost 가 grpc 서비스를 구축하기 위해 stream.proto file 을 작성하였으며, 이는 protoc 에 의해 compile 되어 go 코드로 변환된다. stream.proto file 에 대해 간단히 소개하자면 StreamService 라는 구조체를 기반으로 BifrostStream이라는 함수를 가지며, Envelope 라는 자료형을 추가로 구성한다.

서버측에서 RegisterStreamServiceServer 를 통해 서버를 등록하고 클라이언트 측에서 NewStreamServiceClient 를 통해 streamServiceClient 객체를 생성하고, streamServiceClient.BifrostStream 을 호출하는 방식으로 Envelop 를 송수신 한다.
