Abstract: Technologies for protocol-agnostic network packet segmentation includes determining whether a size of a payload of a network packet to be transmitted by the compute device exceeds a maximum size threshold and segmenting the payload into a plurality of segmented payloads if the size of the payload exceeds the maximum size of threshold. The payload may be segmented based on segmentation metadata associated with the network packet.

Abstract: Processing circuitry extracts, from multiple types of data frames, a specific data frame having a data length that can be shortened based on data frame type. The processing circuitry reconstructs the specific data frame as a new data frame having a shorter data length by updating the data length code included in the specific data frame to indicate the shorter data length.

Abstract: A network device includes multiple interconnected network chips where the packet processing functionality is distributed between ingress and egress pipelines. TCP MSS clamping can be implemented in the egress pipeline. Processing in the egress pipeline can identify the presence of a TCP MSS value in the packet. The egress pipeline can compare the packet TCP MSS value with a user configured TCP MSS value. The egress pipeline can replace the packet TCP MSS value with the user configured TCP MSS value if the former is greater than the latter, and recompute a checksum. The packet with the replaced TCP MSS value and replaced checksum is then forwarded from the switch toward its eventual destination.

Abstract: Devices and techniques for packet arbitration for buffered packets in a network device are described herein. A packet can be received at an input of the network device. The packet can be placed in a buffer for the input and a characteristic of the packet can be obtained. A record for the packet, that includes the characteristic, is written into a data structure that is independent of the buffer. Arbitration, based on the characteristic of the packet in the record, can then be performed among multiple packets to select a next packet from the buffer for delivery to an output.

Abstract: Disclosed herein are system, method, and computer program product embodiments for providing traffic visibility in a network. An embodiment operates by a third-party component receiving a copy of a first data packet during a first period of time. The third-party component extracts a first network parameter associated with the first period of time from the copy of the first data packet. The third-party component then predicts a baseline of normalcy for the first network parameter during a second period of time after the first period of time based on data associated with a copy of a second data packet and the first network parameter. Thereafter, the third-party component receives a copy of a third data packet during the second period of time, and extracts a second network parameter from the copy of the third data packet. The third-party component then determines that the second network parameter of the copy of the second data packet is an anomaly based on the baseline of normalcy for the first network parameter.

Abstract: Disclosed herein are system, method, and computer program product embodiments for providing traffic visibility in a network. An embodiment operates by a third-party component in communication with a network component—each located at a network's edge—maintaining a rule table including a first rule comprising first identifiers and a first action for deriving a first packet characteristic. The third-party component receives a first packet copy including second identifiers from the network component. Upon the second identifiers matching the first identifiers, the third-party component determines the rule table's second rule includes a second action for deriving a second packet characteristic. Thereafter, the third-party component receives a second packet copy comprising third identifiers from the network component. Upon the third identifiers matching the first identifiers, the third-party component identifies the rule table's second rule and performs the second rule to derive the second packet characteristic based on the second packet's data.

Abstract: Disclosed herein are related to communication systems and methods for converting between lossy communication protocol packets and lossless communication protocol packets. In one aspect, the communication system includes a server, a set top box, and an intermediate node. In some embodiments, the intermediate node is configured to receive a lossy communication protocol packet from the server, convert the lossy communication protocol packet to a lossless communication protocol packet, and transmit the converted lossless communication protocol packet to the set top box.

Abstract: A method of generating a network topology map in a datacenter comprising a network manager server and a set of host machines is provided. Each host machine hosts a set of data compute nodes (DCNs). The method receives information regarding the configuration of each of a set of logical networks from the network manager server. Each logical network is connected to several DCNs. The method identifies logical connections configured between the DCNs using the configuration of the overlay networks. The method generates a network topology map based on the identified logical configuration. The network topology identifies the DCNs that are connected to each overlay network. The method displays the network topology map on a graphical user interface.

Abstract: The embodiments of the present disclosure provide a packet forwarding method, a packet forwarding apparatus, and an electronic device. In the embodiments of the present disclosure, by setting up a corresponding outbound-interface-direction-queue scheduling period for the outbound interface on the network device, a number of time slices in the outbound-interface-direction-queue scheduling period, and a length of one time slice, and allocating corresponding time slices in the outbound-interface-direction-queue scheduling period to the outbound-interface-direction queues corresponding to the outbound interface, such that the network device can schedule, on each time slice in the outbound-interface-direction-queue scheduling period, packets in the outbound-interface-direction queue corresponding to the time slice. This can realize that the delay of waiting for scheduling outbound-interface-direction queues is maintained between the worst delay and the best delay as discussed above, realize deterministic delay of waiting for scheduling outbound-interface-direction queues, and thus realize deterministic delay of packet forwarding.
