Combined pipelined classification and address search method and apparatus for switching environments
TL;DR: In this paper, a packet switching node having a pipelined packet processing architecture processing packets received via an input port associated with the packet-switching node is presented, where the method performed by the apparatus includes: determining a packet frame type of the packet received; selectively extracting packet header field values specific to a packetframe type, the extracted packet header fields field value including packet addressing information; ascribing to the packet a preliminary action to be performed in respect of packet; searching packet switching information tracked by the packet, and formulating a preliminary switch response for the packet; class
Patent
Method and apparatus providing rapid end-to-end failover in a packet switched communications network
TL;DR: In this article, a hardware-based failover scheme enabling rapid end-to-end recovery is provided, where the hardware logic periodically generates, transmits, receives, and processes heartbeat packets, sent from one end of the communications network to another, and then returned back.
Patent
Buffer management for support of quality-of-service guarantees and data flow control in data switching
TL;DR: In this article, a method of utilizing shared memory resources in switching Protocol Data Units (PDUs) at a data switching node is presented, which includes reserving: a temporary memory storage portion for storing PDUs prior to queuing for processing thereof, a Class-of-Service memory storage component to provide support QoS guarantees, a shared memory-pool portion and an input port memory storage part enabling non-blocking input port flow control Provisions are made for PDU discard decisions to be delayed until after PDU headers are inspected subsequent to the receipt of each PDU.
Patent
Credit-based pacing scheme for heterogeneous speed frame forwarding
TL;DR: In this article, a credit-based pacing scheme for heterogeneous speed frame forwarding is proposed, where a credit scheme is used to arbitrate among multiple pacing modules per device, each forwarding data at a different rate.
Patent
Fast data path protocol for network switching
TL;DR: A protocol and header format of a network architecture for communication between a plurality of network devices is described in this article. But the protocol is not suitable for the use of data frames in the context of wireless networks.
