Abstract

A method and apparatus for an enhanced datagram packet switched computer network is disclosed. The invention processes network datagram packets in network devices as separate flows, based on the source-destination address pair contained in the datagram packet itself. As a result, the network can control and manage each flow of datagrams in a segregated fashion. The processing steps that can be specified for each flow include traffic management, flow control, packet forwarding, access control and other network management functions. The ability to control network traffic on a per flow basis allows for the efficient handling of a wide range and a large variety of network traffic, as is typical in large-scale computer networks, including video and multimedia type traffic. The amount of buffer resources and bandwidth resources assigned to each flow can be individually controlled by network management. In the dynamic operation of the network, these resources can be varied based on actual network traffic loading and congestion encountered. The invention also teaches an enhanced network access control method which can selectively control flows of datagram packets entering the network and traveling between network nodes. This new network access control method also interoperates with existing media access control protocols, such as used in the Ethernet or 802.3 local area network. An important aspect of the invention is that it does not require any changes to existing network protocols or network applications. This is accomplished by specifying the flow control, traffic management and network control functions via network management. Applications or network protocols that require the network to provide a certain level of bandwidth or performance can request such services via the network management function.
