Unordered multi-path routing in a pcie express fabric environment
A method of providing unordered packet routing in a multi-path PCIe switch fabric is provided. Fabric egress port congestion is measured and distributed to all ports within a switch and to neighboring switches. An unordered route choice vector is generated by table lookup. The local congestion mask vector identifies which of these choices has local congestion. A next hop masked choice vector generated by table lookup is gated with the next hop congestion mask vectors, received from neighboring switches, to identify the choices that have next hop congestion. Congested choices are excluded by masking. If multiple choices remain at the conclusion of the masking process, then a selection is made by round-robin among the surviving choices. If no choices remain, the selection is made by round robin among the original choices. The final selection is mapped to an egress port on the switch by table lookup.

Distributed Joint Admission Control And Dynamic Resource Allocation In Stream Processing Networks
InactiveUS20080304516A1Error preventionFrequency-division multiplex detailsLocal congestionDynamic resource
Methods and apparatus operating in a stream processing network perform load shedding and dynamic resource allocation so as to meet a pre-determined utility criterion. Load shedding is envisioned as an admission control problem encompassing source nodes admitting workflows into the stream processing network. A primal-dual approach is used to decompose the admission control and resource allocation problems. The admission control operates as a push-and-pull process with sources pushing workflows into the stream processing network and sinks pulling processed workflows from the network. A virtual queue is maintained at each node to account for both queue backlogs and credits from sinks. Nodes of the stream processing network maintain shadow prices for each of the workflows and share congestion information with neighbor nodes. At each node, resources are devoted to the workflow with the maximum product of downstream pressure and processing rate, where the downstream pressure is defined as the backlog difference between neighbor nodes. The primal-dual controller iteratively adjusts the admission rates and resource allocation using local congestion feedback. The iterative controlling procedure further uses an interior-point method to improve the speed of convergence towards optimal admission and allocation decisions.

Congestion control and QOS in noc by regulating the injection traffic
Systems and methods described herein are directed to solutions for NoC interconnects that provide congestion avoidance and end-to-end uniform and weighted-fair allocation of resource bandwidths among various contenders in a mesh or torus interconnect. The example implementations are fully distributed and involve using explicit congestion notification messages or local congestion identification for congestion detection. Based on the congestion level detected, the injection rates of traffic at various agents are regulated that avoids congestion and also provides end-to-end QoS. Alternative example implementations may also utilize end-to-end credit based flow control between communicating agents for resource and bandwidth allocation of the destination between the contending sources. The resource allocation is performed so that both the weighted and strict bandwidth allocation QoS policies are satisfied.

Domain based congestion management
The Domain-based Congestion Management method and apparatus detects and regulates congestion in a Diff-serv network. It uses an improvRED method for congestion detection at the core routers and token bucket filters for traffic regulation at the ingress nodes. In addition, improvRED also provides feedback control. ImprovRED uses three thresholds for detecting congestion: a minth, a maxth and a FeedbackThreshold, which takes a value between the minth and the maxth thresholds. Whenever the average queue size is greater than minth and less than Feedback-Threshold, all outgoing packets are marked appropriately to indicate a potential onset of a congestion period. When the average queue size is greater than FeedbackThreshold (but less than maxth) packets are dropped probabilistically and all the outgoing packets are marked appropriately to denote the dropping phase. When the average queue size is greater than the maximum threshold, all incoming packets are dropped. Feedback, in the form of a Local Congestion Notification (LCN) message, is used to notify the ingress nodes of a likely onset of congestion. Ingress nodes immediately respond to the congestion notification by appropriately regulating their respective traffic rates (i.e., the amount of packets they inject into the Diff-serv network). The amount of traffic (or data packets) injected into the core of the Diff-serv domain is controlled by a token bucket filter at each of the ingress nodes.
