Method and apparatus for automatic congestion avoidance for differentiated service flows

Mark David Bellows
TLDR
In this paper, a method and apparatus for implementing automatic congestion avoidance for differentiated service flows in a communications network is provided, where a bandwidth control signal representing congestion information is identified and dual transmit probabilities are calculated for each flow.
Abstract: 
A method and apparatus are provided for implementing automatic congestion avoidance for differentiated service flows in a communications network. A bandwidth control signal representing congestion information is identified. Responsive to the identified bandwidth control signal, dual transmit probabilities are calculated for each flow. The dual transmit probabilities include a first transmit probability for a first color and a first transmit probability for a second color. A marked color for a packet is identified. The marked packet color and the calculated dual transmit probabilities are selectively utilized for making a packet discard determination.

Managing routing information for tunnel endpoints in overlay networks

Kit Chiu Chu, +5 more
TL;DR: In this paper, a first tunnel endpoint in an overlay network may receive an encapsulated packet from a second tunnel endpoint, based on another packet originating from a source host that is associated with the source tunnel endpoint.

Recovering from virtual port channel peer failure

Ayaskant Pani, +3 more
TL;DR: In this paper, the first and second vPC peers may be paired to create a vPC having a virtual address, and the first vPC peer can continue to advertise the association between the endpoint host and the virtual address.

System and method for multi-path load balancing in network fabrics

Mohammadreza Alizadeh Attar, +3 more
TL;DR: In this article, a source leaf device receives a packet and identifies a flowlet associated with the packet and a destination leaf device to which the packet is to be transmitted, and then transmits the packet to the destination leaf devices via the uplink.

Policy enforcement proxy

Thomas J. Edsall, +2 more
TL;DR: In this article, the authors describe a system for implementing a policy enforcement proxy in non-transitory computer-readable storage media (NTRM) and demonstrate the use of a policy lookup based on the source and destination groups.

Apparatus and methods for managing packets in a broadband data stream

Glenn Gracon, +3 more
TL;DR: A packet scheduler includes a packet manager interface, a policer, a congestion manager, a scheduler, and a virtual output queue (VOQ) handler as mentioned in this paper, which assigns a priority to each packet.

Retro flow control for arriving traffic in computer networks

James Allen, +7 more
TL;DR: In this paper, the decision within a packet processing device to transmit a newly arriving packet into a queue to await further processing or to discard the same packet is made by a flow control method and system.

Quality of service functions implemented in input interface circuit interface devices in computer network hardware

Kenneth James Barker, +4 more
TL;DR: In this article, the decision to discard or forward a packet is made by a flow control mechanism, upstream from the forwarding engine in the node of a communication network, which includes a switch with mechanism to detect congestion in the switch and return a binary signal B indicating congestion or no congestion.

Router device and priority control method for use in the same

Bun Mizuhara, +1 more
TL;DR: In this article, the authors present a router device capable of using separated queues with arbitrary fineness and flexibly achieving assurance and separation of traffic. But their work is limited to the use of in-device cell header information.
