In one example, a network device includes a network interface that receives a packet, a storage card that stores session data for monitored network sessions, a plurality of service processing cards that process packets of respective subsets of the network sessions, wherein each of the service processing cards comprises a respective memory to store session data for the respective subset of the network sessions processed by the corresponding service processing card, and a switch fabric coupled to the network interface, the storage card, and the plurality of service processing cards. One or more of the plurality of service cards process the received packet based on the session data stored by the storage card. The one or more of the plurality of service cards retrieve the session data for the network session to which the packet corresponds from the storage card and store the retrieved session data in the respective memory.

Storing session information in network devices

A network device receives, from a remote user device, a requested test that includes test Internet protocol (IP) packets, and converts the test IP packets into hardware test commands. The network device also performs, based on the hardware test commands, the requested test on a component of a network device card to produce hardware test results. The network device further converts the hardware test results into test results in an IP packet format, and provides the tests results in the IP packet format to the remote user device.

Remote network device component testing

In general, the invention is directed to techniques for improving memory utilization in a priority queuing system of a network device. More specifically, a priority queue memory management system is described in which memory pages are assigned to the various priority queues in order to implement an efficient first in, first out (FIFO) functionality. The dynamic memory techniques described herein allow the multiple priority queues to share a common memory space. As a result, each priority queue does not require a pre-allocated amount of memory that matches the aggregate size of the packets that must be buffered by the queue.

Memory utilization in a priority queuing system of a network device

A network device includes a receiver component that generates flow control information. The network device also includes a transmitter component that receives a packet for forwarding to the receiver component, receives flow control data for the packet from the receiver component, and provides the packet and the flow control data for the packet to a fabric component. The fabric component performs a congestion management operation for the packet, and forwards the packet to the receiver component based on the flow control data and results of the congestion management operation.

Oversubscribed packet stream-based interconnect protocol

In general, techniques are described for reducing response times to retrieve content in an intermediate network device. In particular, the intermediate network device receives a packet from a client device of a first network that requests content from a remote network device of a second network, inspects the packet to determine whether the requested content has been previously cached to either of a first and a second memory of the device, issues a request to load the requested content from the second memory to the first memory based on the determination and queues the packet within in the queue. After queuing the packet, the intermediate network device then processes the packet to assemble a response that includes the content from the memory.
