摘要： The invention relates to enabling differential forwarding in address-based carrier networks such as Ethernet networks. There is described a method of and connection controller for establishing connections (76, 77) in a frame-based communications network comprising nodes (71-75 and 78) such as Ethernet switches. The connections are established by configuring, in various of the nodes, mappings for forwarding data frames, such as Ethernet frames. The mappings are from a combination of a) a destination (or source) address corresponding to a destination (or source) node (73) of the connection and b) an identifier, such as a VLAN tag. The mappings are to selected output ports of the various nodes. By using the combination of destination (or source) address AND identifier, the mappings enable data frames belonging to different connections (76, 77) to be forwarded differentially (ie forwarded on different output ports) at a node (75) despite the different connections having the same destination node. This enables flexibility in routing connections and the ability to perform traffic engineering.

摘要： A controller for distributing logical control plane data to other controllers is described. The controller includes an interface for receiving user inputs to define logical datapath sets. The controller includes a translator for translating the user inputs to output logical control plane data. The logical control plane data is for subsequent translation into logical forwarding plane data by several other controllers. The controller includes a scheduler for (1) storing the output logical control plane data in a plurality of storage structures, each storage structure corresponding to one of the other controllers and (2) sending the output logical control plane data to the other controllers from the corresponding storage structure.

摘要： A method and network device provides port scheduling for data ports in the network device. The network device may assign data ports of the network device into port groups according to port characteristics of the data ports. The network device may schedule processing time slots for active data ports by determining a selected port group based on group selection parameters. The network device may then determine a selected data port from the selected port group using port selection criteria. The port selection criteria may maintain minimum and maximum packet spacing requirements for the data ports of a port group. The network device may also maintain an active ports list to disqualify inactive data ports from selection.

摘要： A method of detecting physical connections between a root bridge node and layer-2 bridge nodes organised in a layer-2 cloud. The method comprises sending a query message from a sending port of the root bridge node and starting a timer set to a waiting interval. After the timer expired, if a response message to the query message is not received or is received at the sending port then only the sending port is associated with said layer-2 cloud. Alternatively, if a response message is received at a port other than the sending port then the sending port and the receiving port are associated with said layer-2 cloud. A bridge node and a layer-2 communications network are also disclosed.

摘要： Techniques are described for determining latency in a physical network that includes a number of network devices over which packets travel. A virtual network controller receives a plurality of messages from a plurality of network devices in a network, each of the messages including a packet signature comprising a hash of an invariant portion of an original packet that uniquely identifies the original packet, an identifier of one of the plurality of network devices from which the respective message was received, and a timestamp indicating a time an original packet was processed by the network device from which the respective message was received. The virtual network controller determines a latency of a physical network path in the network based on analysis of contents of the identified messages having a common packet signature.

摘要： Systems and methods are presented relating to a three stage crossbar based switching system and a scheduling method for transmission of data packets and associated request and grant tokens. The first stage and third stage portions of the switching system contain TDM crossbars, which are interconnected by a middle stage set of crossbars. In an embodiment, the system switching module is a m×m crossbar switch comprising m inputs and m outputs. The switch has a size m2×m2 formed from m×m crossbar modules. Scheduling of data packet servicing is on a frame by frame basis relating to selection based on port addresses and port address groups. Further, time slot interchange is utilized to address time slot mismatch.

摘要： Aspects of port empty transition scheduling are described herein. In one embodiment, when one or more cells are added to a queue in a network communications device, an enqueue indicator is generated. The enqueue indicator identifies a number of cells added to the queue. With reference to the enqueue indicator, a queue scheduler maintains a count of cells enqueued for communication and issues a port pick credit for a port of the network communications device. A port scheduler schedules a pick for communicating over the port with reference to the port pick credit and forwards the pick to the queue scheduler. In turn, the queue scheduler forwards a queue pick to the queue, and at least one of the cells is forwarded to dequeue logic. According to aspects of the embodiments described herein, empty port scheduling inefficiencies may be avoided and network throughput increased.
