摘要： Embodiments of the present invention provide a system that transfers data between the components in the computer system through a switch. In these embodiments, the switch includes multiple switch chips which are coupled together and are configured to collectively function as a switch. During operation, each switch chip, receives cells from the subset of the set of inputs and selectively transfers each of the cells to at least one output of the subset of the set of outputs coupled to the switch chip or of the subset of the set of outputs coupled to the other switch chips.

摘要： Apparatus and methods for real-time traffic classification based on off-line determined traffic classification rules are provided. Traces of real traffic are obtained and subjected to statistical analysis. The statistical analysis identifies the multidimensional domain space of characteristic traffic parameters. Classification rules associated with the identified domains are derived and provided to traffic classification points for real-time traffic classification. Traffic classification points, typically edge network nodes, sample packets in aggregate streams with a predetermined probability. Statistical information regarding the sampled flows is tracked in a table, the number of time a flow was sampled providing a probabilistic measure of the flow's duration before the flow terminates. The table entries, which predominantly track high bandwidth flows, are subjected to the classification rules for real-time classification of the sampled flows. Optionally, rules include an action to be taken in respect of flows having characteristics matching thereof. Advantages are derived from low overhead on-line real-time classification of high-bandwidth flows at low overheads before flow termination.

摘要： Embodiments of the present invention provide a system that schedules the transfer of cells in a switch. The system starts by receiving a set of cells to be transferred from a set of inputs of the switch to a set of outputs of the switch. The system includes S subschedulers, wherein each subscheduler processes N scheduling waves in sequence to generate a conflict-free transfer schedule for a given time slot for a matrix of transfer elements in the switch. The system then operates the subschedulers in parallel to generate S transfer schedules to transfer the cells from the set of inputs of the switch to the set of outputs of the switch during S time slots.

摘要： The sharing of forwarding states between multiple traffic paths is described. There is a described a method for establishing a data traffic path in a communication network from a first node towards a second node. The method includes searching a set of pre-existing forwarding states for a pre-existing forwarding state associated with the first node for defining the traffic path from the first node towards the second node. If the pre-existing forwarding state for defining the traffic path cannot be found in the set of pre-existing forwarding states, then a new forwarding state for defining the traffic path from the first node towards the second node is generated the new forwarding state is used to establish the traffic path from the first node towards the second node. An apparatus implementing the method is described. The sharing of forwarding states as described may be used in MPLS enabled networks.
