摘要： In a network packet router having one or more ingress and egress ports, a method is implemented at an ingress port for egress pass/drop determination for packets, comprising the steps of (a) noting header combinations and values , and egress port destination for incoming packets ; (b) comparing the header combinations and values with rule sets associated with the header combinations and values including egress port identities, and (c) returning a determination of pass or drop for the packet.

摘要： A line card for a data packet router interfaces to a high-speed standard data link and has a first portion interfacing to the router and having a plurality of slower ports, and a second portion having a framer (47) compatible with and coupled to the data link. The framer (47) is coupled through an ingress and an egress data path (51, 49) between the framer (47) and the slower ports, each with separate ingress buffers and egress buffers for each port. An interface control circuit controls data packet transfers between the slower ports and the framer in both directions. In a preferred embodiment a function is used by the control circuit to map packets from the link to the ports, using keys extracted from the incoming packets. For an IP packet the key is the source address, destination address (SA/DA) pair, which constrains packets for same IP conversations to be routed by the same path.

摘要： A method optimizes performance in a data network including a plurality of ingress ports and output queues. Ingress rates of a plurality of flows are monitored, where each flow includes a sequence of packets passing from an ingress port to an output queue and each flow has a profile related to flow characteristics. Each packet is marked with a marking based on criteria including the ingress flow rate and the flow profile. A drop probability of each packet is adjusted at an output queue according to a value of a drop function taken as a function of a queue size. The drop function is selected according to the marking on the packet. The drop functions are zero for queue sizes less than a lower threshold range and positive for queue sizes greater than the lower threshold range. By selecting drop functions according to ingress flow rate measurements and flow profiles, the data network can be optimized for overall system performance.

摘要： In a communication system having a plurality (11) communication ports, a hierarchical bond communication interface has a logical interface (1100) as a component of the bond at a top level of the hierarchy, and a first subjugate logical interface at a second level of the hierarchy as a component of the top-level logical interface. The communication system has a control mechanism whereby thresholds may be set to determine up or down status of hierarchical bonds for use in communication, according to characteristics of components of the bonds.

摘要： An apparatus and method for monitoring data flow at a node on a network are disclosed. A menory location or 'bucket' is allocated to each of a plurality of links and classes of service at the node. A free-running counter is incremented at a rate determined by the maximum allowable data rates on the various links and classes of service. When a data packet is received at a particular link and class of service, the corresponding memory location or bucket is adjusted or 'leaked' by subtracting the present counter value from the present bucket contents. That difference is then added to the number of units of data, i.e., bytes or groups of bytes of data, contained in the incoming packet. That sum is then compared with a predetermined threshold determined by the allowable dayta rate associated with the link and class of service. If the threshold is exceeded, then the incoming data packet is marked accordingly. The system can include multiple stages or monitoring such that multiple thresholds can be used to assign one of multiple discard eligibility values to the incoming packet.

摘要： A method for managing data traffic in nodes in a fabric network (Fig. 2), each node having internally-coupled ports, follows the steps of establishing a managed queuing system (209) comprising one or more queues associated with each port, for managing incoming data traffic; and accepting or discarding data directed to a queue according to the quantity of data in the queue relative to queue capacity. In one preferred embodiment the managed system accepts all data directed to a queue less than full, and discards all data directed to a queue that is full. In some alternative embodiments the queue manager (209) monitors quantity of data in a queue relative to queue capacity, and begins to discard data at a predetermined rate when the quantity of queued data reaches the threshold. In other cases the queue manager increases the rate of discarding as the quantity of queued data increases above the preset threshold, discarding all data traffic when the queue is full.

摘要： A data structure has a list of event objects (904), one or more producers (906) creating the event objects for the list, and a finite set of consumers (907) accessing the object list. The structure is characterized in that the event objects are each associated with a first reference number indicating the number of consumers currently accessing the event object, and in that, as each consumer completes access the reference number is decremented, and when the reference number for an event object is zero, and the event object is at the head of the list, indicating that all consumers have accessed the object, that event object is removed from the list. A user of the structure for propagating route changes to nodes in a multiple-processor router, and to peer routers in a network is also taught.

摘要： An apparatus and method for efficient hashing uses both an identifying portion of a data packet, e.g., source and destination ID, and an identifying value of the node, e.g., the IP address of the node, to generate a hash result. By inserting a unique value into the hash operation at each node, the invention effectively provides for a different hash implementation at each node. As a result, in situations where multiple paths or multiple links within a path are available to forward packets, traffic can be split over the multiple paths and links. Inefficient utilization of network links found in prior systems which use the same hash operation at each node are eliminated.
