摘要： A tag mask generation method comprises receiving a section_selector flag indicating whether a tag mask for a section of a network packet is to be generated; receiving from a parser a parse information for the network packet, wherein the parse information includes a section_pointer that indicates a location of the section in the network packet; generating a pointer based on the section_pointer when the section_selector indicates that the tag mask for the section is to be generated; receiving a base mask for the section; and generating the tag mask via a shifter by shifting the base mask by the amount indicated by the pointer. The parse information may further include a section_pointer_valid flag indicating whether the section is included in the network packet, and the method may further comprise including the tag mask in a combined tag mask when the section_pointer_valid flag indicates that the section is included in the network packet.

摘要： A new approach is proposed that contemplates systems and methods to support flexible reconfiguration of a network chip by an external entity, such as a baseboard management controller (BMC), while maintaining a secured environment for the chip so that it can booted securely. Specifically, the network chip is configured to designate one or more of its networking ports to the BMC and allow the BMC to configure the designated networking ports without violating the secure areas of the network chip. To this end, the network chip is configured to allow the BMC to access a plurality of registers of the network chip via an Network Controller Sideband Interface (NC-SI) block of the network chip by issuing a plurality NC-SI compliant commands. By configuring the designated networking ports, the BMC is configured to establish a data path to a management software of a platform that includes the network chip though the designated networking ports.

摘要： A method for parsing network packets via one or more clusters configured to parse network packets comprises receiving one or more packets to be parsed; determining a candidate cluster of the one or more clusters for parsing the one or more packets; transmitting the one or more packets to the candidate cluster; launching the candidate cluster to parse the one or more packets when a launch condition is met; and receiving parse results for the one or more packets from the candidate cluster. The launch condition may be met after transmitting the one or more packets meets a fraction of a parsing capacity of the candidate cluster. The fraction may be one such that the transmitting the one or more packets meets a parsing capacity of the candidate cluster. The launch condition may also be met when a time elapsed since a previous cluster was launched reaches a delay limit.
