+Dubbo-go has supported many RPC protocols, like Triple, Dubbo, JSONRPC, gRPC, HTTP, HTTP2. The Triple, Dubbo and gRPC protocols supported security connections via TLS.
 
 - Triple is the supported protocol of Dubbo3 ecology, and is gRPC extended protocol based on HTTP2, which is compatible with gRPC service.In other words, **on the basis of gRPC's reliable invocation, it adds Dubbo's service governance capability.**
 - Dubbo protocol is tradition Dubbo ecology protocol, which is compatible with Dubbo 2.x, and is a good choice for cross-language invocation between GO and Java legacy service.
-- HTTP support：As you can see in the figure above, you can invoke Triple/Dubbo service using HTTP protocol through [dubbo-go-pixiu](https://github.com/apache/dubbo-go-pixiu) gateway.

+Dubbo-go 生态覆盖多种网络协议：Triple、Dubbo、JSONRPC、gRPC、HTTP、HTTP2 等。Triple、Dubbo 和 gRPC 协议支持基于 TLS 的安全通信。
 
 - Triple 协议是 Dubbo3 生态主推的协议，是基于 gRPC 的扩展协议，底层为HTTP2，可与 gRPC 服务互通。**相当于在 gRPC 可靠的传输基础上，增加了 Dubbo 的服务治理能力。**
 - Dubbo 协议是 Dubbo 生态的传统协议，dubbo-go 支持的 dubbo 协议与dubbo2.x 版本兼容，是 Go 语言和旧版本 Dubbo 服务互通的不错选择。
