Abstract: Systems and methods for increasing the speed with which a network device can process “heartbeat” packets that are transmitted between the network device and its peers to verify that the communication links between them are active, or to detect when the communication links go down (i.e., are inactive). Received heartbeat packets are processed primarily by a switching application specific integrated circuit (ASIC) rather than a CPU of the network device. The switching ASIC identifies heartbeat sessions corresponding to received heartbeat packets and resets aging timers for these sessions if the timers have not already expired. The reduced processing and faster timing mechanism of the switching ASIC enables the network device to accommodate spikes in the received packet rate.

Abstract: A system for efficiently determining a set of next-hop switches from a switch is provided. During operation, the system can determine the plurality of next-hop switches for an Internet Protocol (IP) address prefix. The system can then store, in an entry of a forwarding data structure of the switch, a list of identifying information indicating the plurality of next-hop switches corresponding to the IP address prefix. The identifying information for the plurality of next-hop switches can be stored in the list in an order of preference for forwarding traffic matching the IP address prefix. Upon receiving a packet with a destination IP address matching the IP address prefix, the system can select the entry from the forwarding data structure for determining a next-hop switch for forwarding the packet. The system can then determine the next-hop switch for the packet from the entry based on the order of preference.

Abstract: With ever-increasing capacities and performance demanded in new storage devices, the number of control table data entries are increased to store more updates stemming from the increased number of read and/or write operations. To avoid becoming a bottleneck, devices, such as storage devices, and other similar methods and systems as described herein efficiently manage control table sets to reduce latency. This can be accomplished by designating a specific position for each control table set and storing updates to such control table sets in a designated position. Furthermore, data can be efficiently kept in the volatile memory, such as SRAM, or evicted from the volatile memory to the non-volatile memory, such as NAND. Determinations can occur for when the read/write operations should be performed using volatile memory or non-volatile memory. These determinations can be decided dynamically and based on the storage device state and incoming workload, resulting in lower overall latencies.

Abstract: In one embodiment, associated differential processing of decapsulated packets is performed using Service Function Instances (SFIs) identified by Service Function Values (SFVs) derived from their encapsulating transport packets.
