2.1 Transport

  • Article

Mailslot writes are delivered over the NetBIOS datagram service by using one of the following transports:

  • NetBIOS over UDP datagram service, as specified in [RFC1001] section 5.4. For this transport, the maximum allowed size for the MailslotName and Databytes fields (see section 2.2.1) of a mailslot write message is 443 bytes.

  • NetBIOS over IPX.

  • NetBIOS Extended User Interface, as specified in [NETBEUI].

For NetBIOS Extended User Interface and NetBIOS over IPX, the maximum size is dependent on the frame size of the underlying physical media. When using UDP as the underlying transport, the protocol implementation SHOULD restrict the maximum allowed data in the MailslotName and Databytes fields (see section 2.2.1) of a mailslot write message to no more than 443 bytes.<2>
