title: Is there some way to handle SIP, RTP, DIAMETER, M3UA traffic in Kubernetes?
body: <p>From a quick read of the Kubernetes docs, I noticed that the kube-proxy behaves as a Level-4 proxy, and perhaps works well for TCP/IP traffic (s.a. typically HTTP traffic). </p>
  
  <p>However, there are other protocols like SIP (that could be over TCP or UDP), RTP (that is over UDP), and core telecom network signaling protocols like DIAMETER (over TCP or SCTP) or likewise M3UA (over SCTP). Is there a way to handle such traffic in application running in a Kubernetes minion ?</p>
  
  <p>In my reading, I have come across the notion of Ingress API of Kuberntes, but I understood that it is a way to extend the capabilities of the proxy. Is that correct ? </p>
  
  <p>Also, it is true that currently there is no known implementation (open-source or closed-source) of Ingress API, that can allow a Kubernetes cluster to handle the above listed type of traffic ?</p>
  
  <p>Finally, other than usage of the Ingress API, is there no way to deal with the above listed traffic, even if it has performance limitations ? </p>
