Abstract: In one embodiment, packet memory and resource memory of a memory are independently managed, with regions of packet memory being freed of packets and temporarily made available to resource memory. In one embodiment, packet memory regions are dynamically made available to resource memory so that in-service system upgrade (ISSU) of a packet switching device can be performed without having to statically allocate (as per prior systems) twice the memory space required by resource memory during normal packet processing operations. One embodiment dynamically collects fragments of packet memory stored in packet memory to form a contiguous region of memory that can be used by resource memory in a memory system that is shared between many clients in a routing complex. One embodiment assigns a contiguous region no longer used by packet memory to resource memory, and from resource memory to packet memory, dynamically without packet loss or pause.

Abstract: In one embodiment, a time period is identified in which probe packets are to be sent along a path in a network based on predicted user traffic along the path. The probe packets are then sent during the identified time period along the path. Conditions of the network path are monitored during the time period. The rate at which the packets are sent during the time period is dynamically adjusted based on the monitored conditions. Results of the monitored conditions are collected, to determine an available bandwidth limit along the path.

Abstract: One embodiment of the present invention provides a switch. The switch includes a fabric switch module and a border module. The fabric switch module maintains a membership in a first fabric switch. The fabric switch includes a plurality of switches and operates as a single logical switch. The border module determines that the egress switch identifier in a first encapsulation header of a first packet is associated with a switch outside of the fabric switch. The first packet is forwardable in the first fabric switch based on the first encapsulation header. In response to the determination, the border module changes the ingress switch identifier in the first encapsulation header of the first packet to a first virtual switch identifier associated with a first virtual switch. This first virtual switch externally represents the first fabric switch.
