Parameters

module Time : Mirage_time.S

module Random : Mirage_random.S

module Netif : Mirage_net.S

module Ethernet : Ethernet.S

module Arpv4 : Arp.S

module Ip : Tcpip.Ip.S with type ipaddr = Ipaddr.t

module Icmpv4 : Icmpv4.S

module Udp : Tcpip.Udp.S with type ipaddr = Ipaddr.t

module Tcp : Tcpip.Tcp.S with type ipaddr = Ipaddr.t

Signature

include Tcpip.Stack.V4V6
  with module IP = Ip
   and module TCP = Tcp
   and module UDP = Udp

type t

The type representing the internal state of the dual IPv4 and IPv6 stack.

val disconnect : t -> unit Lwt.t

Disconnect from the dual IPv4 and IPv6 stack. While this might take some time to complete, it can never result in an error.

module UDP = Udp

module TCP = Tcp

module IP = Ip

val udp : t -> UDP.t

udp t obtains a descriptor for use with the UDP module, usually to transmit traffic.

val tcp : t -> TCP.t

tcp t obtains a descriptor for use with the TCP module, usually to initiate outgoing connections.

val ip : t -> IP.t

ip t obtains a descriptor for use with the IP module, which can handle raw IPv4 and IPv6 frames, or manipulate IP address configuration on the stack interface.

val listen_udp : t -> port:int -> UDP.callback -> unit

listen_udp t ~port cb registers the cb callback on the UDP port and immediately return. If port is invalid (not between 0 and 65535 inclusive), it raises Invalid_argument. Multiple bindings to the same port will overwrite previous bindings, so callbacks will not chain if ports clash.

deprecated use UDP.listen instead (since mirage-protocols 6.0.0).

val listen_tcp : 
  ?keepalive:Tcpip.Tcp.Keepalive.t ->
  t ->
  port:int ->
  (TCP.flow -> unit Lwt.t) ->
  unit

listen_tcp ~keepalive t ~port cb registers the cb callback on the TCP port and immediately return. If port is invalid (not between 0 and 65535 inclusive), it raises Invalid_argument. Multiple bindings to the same port will overwrite previous bindings, so callbacks will not chain if ports clash. If ~keepalive is provided then these keepalive settings will be applied to the accepted connections before the callback is called.

deprecated use TCP.listen instead (since mirage-protocols 6.0.0).

val listen : t -> unit Lwt.t

listen t requests that the stack listen for traffic on the network interface associated with the stack, and demultiplex traffic to the appropriate callbacks.

val connect : 
  Netif.t ->
  Ethernet.t ->
  Arpv4.t ->
  Ip.t ->
  Icmpv4.t ->
  Udp.t ->
  Tcp.t ->
  t Lwt.t

connect assembles the arguments into a network stack, then calls `listen` on the assembled stack before returning it to the caller. The initial `listen` functions to ensure that the lower-level layers are functioning, so that if the user wishes to establish outbound connections, they will be able to do so.
