Chapter 9. Supported standards and protocols

Application Interconnect supports the following protocols for your service network:

  • TCP - default
  • HTTP1
  • HTTP2

When exposing or creating a service, you can specify the protocol, for example:

$ skupper expose deployment hello-world-backend --port 8080 --protocol <protocol>

where <protocol> can be:

  • tcp
  • http
  • http2

When choosing which protocol to specify, note the following:

  • tcp supports any protocol overlayed on TCP, for example, HTTP1 and HTTP2 work when you specify tcp.
  • If you specify http or http2, the IP address reported by a client may not be accessible.
  • All service network traffic is converted to AMQP messages in order to traverse the service network.

    TCP is implemented as a single streamed message, whereas HTTP1 and HTTP2 are implemented as request/response message routing.
