摘要： Described herein is a method and system for distributing whole and fragmented requests and responses across a multi-core system. Each core executes a packet engine that further processes data packets and data packet fragments allocated to that core. A flow distributor executing within the multi-core system forwards client requests to a packet engine on a core that is selected based on a value generated when a hash is applied to a tuple comprising a client IP address, a client port, a server IP address and a server port identified in the request. The packet engine maintains each element of the tuple and forwards the request to the selected core. The packet engine can also process data packet fragments by assembling the fragments prior to transmitting them to the selected core, or by transmitting the data packet fragments to the selected core.

摘要： Described herein is a method and system for directing outgoing data packets from packet engines to a transmit queue of a NIC in a multi-core system, and a method and system for directing incoming data packets from a receive queue of the NIC to the packet engines. Packet engines store outgoing traffic in logical transmit queues in the packet engines. An interface module obtains the outgoing traffic and stores it in a transmit queue of the NIC, after which the NIC transmits the traffic from the multi-core system over a network. The NIC receives incoming traffic and stores it in a NIC receive queue. The interface module obtains the incoming traffic and applies a hash to a tuple of each obtained data packet. The interface module then stores each data packet in the logical receive queue of a packet engine on the core identified by the result of the hash.

摘要： The present disclosure presents systems and methods for controlling network traffic traversing an intermediary device based on a license or a permit granted for the intermediary device. The systems and methods control a rate of a traffic of a device in accordance with a rate limit identified by a rate limiting license. A rate limiting manager of an intermediary device that processes network traffic between a plurality of clients and a plurality of servers, may identify presence of a rate limiting license that further identifies a performance level. The rate limiting manager may establish a rate limit based on the performance level of the rate limiting license. A throttler of the intermediary may control a rate of receiving network packets in accordance with the rate limit.
