Abstract: A packet network comprises packet engines (50) that perform packet handling. Cipher engines (60) are provided separately from the packet engines (50) for encryption and/or authentication operations. To preserve relative timing and ordering of data packets, a packet engine (50) performs pre-shaping of data traffic, wherein the packet engine (50) inserts dummy packets (59) into a data flow. The packet engine (50) provides the pre-shaped data traffic to a cipher engine (60).

Abstract: The invention relates to a method for an improved traffic shaping and/or management of IP traffic in a packet processing system, especially as part of a telecommunications network,
wherein the packet processing system comprises a programmable packet switching processor and a traffic shaping processor,
wherein data packets - received by the packet processing system - are ingressed to the packet switching processor, and wherein data packets - transmitted by the packet processing system - are egressed by the traffic shaping processor,
wherein for an improved traffic shaping and/or management of IP traffic, the method comprises the following steps:
-- in a first step, a number of considered data packets, after or while being received by the packet processing system, are received by or ingressed to the packet switching processor,
-- in a second step, subsequent to the first step, the packet switching processor processes the number of considered data packets, appends a queue identification information to each one of the considered data packets, and transmits the considered data packets to the traffic shaping processor,
-- in a third step, subsequent to the second step, the traffic shaping processor applies traffic shaping to the considered data packets by means of using the respective queue identification information of each one of the considered data packets to select a queue for each one of the considered data packets, respectively, and by means of:
-- using a number of queues exceeding 10.000 queues, wherein each one of said queues has a depth or a storing capacity of more than 10 MB,
-- applying a hierarchical scheduling of the considered data packets.

Abstract: Embodiments of the subject disclosure concern a method implemented using network interface controller circuitry for use in association with host computer circuitry. The host computer circuitry is to execute, when the host computer circuitry is in operation, a Linux operating system and a user space application, the Linux operating system, when executed, having a kernel space. The method comprises: providing at least one call associated with the kernel space, the at least one call being usable to set packet filter rules, the packet filter rules corresponding to packet filter rule data, the packet filter rule data being for use in programming packet processing hardware offload circuitry of the network interface controller circuitry to determine, based upon header data of at least one incoming packet and the packet filter rule data, at least one action of the packet filter rules to apply to the at least one incoming packet. The at least one action is configurable to include: at least one network address translation-related operation associated with the header data; dropping the at least one incoming packet; and/or forwarding the at least one incoming packet. When the host computer is in the operation, after registration of at least one device driver of the network interface controller circuitry: the packet filter rule data is to be associated with the network interface controller circuitry via at least one callback function call; and the programming, of the packet processing hardware offload circuitry of the network interface controller circuitry is to be implemented by the at least one device driver associated with the network interface controller circuitry via code references to be associated with the at least one device driver associated with the network interface controller circuitry.

Abstract: Embodiments of this application provide an aggregate rate control method, a device, and a system. The method includes: receiving, by a gateway switch, a flow entry and a link table from a software-defined networking SDN controller, where the flow entry includes at least a match field and a flow-entry instruction, and the link table includes at least a packet processing operation; parsing to obtain header information of a received target data packet, and matching the header information with the match field in the flow entry; when the header information matches the match field in the flow entry, executing a link instruction in the flow-entry instruction in the flow entry, where the link instruction is used to point to the link table; and performing the packet processing operation in the link table, where the packet processing operation is used to discard or buffer the target data packet when a bit rate of an aggregate service flow is greater than a specified maximum aggregate rate. According to the foregoing method, the AMBR can be controlled in an OpenFlow-based network architecture.
