Abstract: A packet parser has a set of marker elements each comprising a one bit latch and connected to store flag values from the results of the application of parser rules. Some marker elements are connected to provide the stored marker values as input to the parser rule logic to be taken into account in the processing of subsequent parser rules and some are connected to control external hardware. Some markers are reset at the end of each packet. A special toggle marker element toggles its value when its address is selected and other marker elements are connected to store, when its own address is selected, the value of the toggle element. Other markers toggle their own value when selected.

Abstract: A microburst monitoring system includes a port and a memory system with an egress queue and a shadow queue that are associated with the port. A networking engine is coupled to the port and the memory system and configured to receive and process packets to provide egress frames for forwarding through the port.

Abstract: An example method for distributed service chaining is provided and includes receiving a packet belonging to a service chain in a distributed virtual switch (DVS) network environment, the packet includes a network service header (NSH) indicating a service path identifier identifying the service chain. The packet is provided to a virtual Ethernet module (VEM) connected to an agentless service node (SN) providing an edge service such as a server load balancer (SLB). The VEM associates a service path identifier corresponding to the service chain with a local identifier such as a virtual local area network (VLAN). The agentless SN returns the packet to the VEM for forwarding on the VLAN. Because the VLAN corresponds exactly to the service path and service chain, the packet is forwarded directly to the next node in the service chain. This can enable agentless SNs to efficiently provide a service chain for network traffic.
