  • System for sending messages in a session using a mixture of protocols and preventing usage of a protocol when the message failing to meet a set of criteria
    Patent number: 5675740
    Abstract: A session-oriented local area network (LAN) application and an ISO 8802-2 protocol driver code will cooperate in a new form of connectionless, session-oriented communication called Sideband. At each session start-up time, the LAN Application will communicate with the enhanced ISO 8802-2 based protocol driver on the local system and the LAN Application and the 8802-2 based protocol driver on the remote system to determine if they all support the Sideband. If Sideband is fully supported by both systems, Sideband will be activated for the session. To communicate on a session which has Sideband active, the LAN Application requests that data is to be sent using the Sideband. A check is performed to see if the data meets Sideband criteria. As Sideband is a connectionless medium, the additional code path needed to set up and track timers and to handle the resend attempts are saved in the protocol.
