摘要： The present disclosure describes systems and methods for load balancing multiple application delivery controllers (ADCs) in multiple tiers. An upper layer of the tier comprises ADCs that load balance the plurality of ADCs of a lower layer of the tier. In order to appropriately share and maintain client IPs for transparent cache redirection scenarios, the transport layer (Transport Control Protocol (TCP)) port range is split among the ADCs of the lower tier. The lower tier ADCs would then create a connection only using a source port assigned to them. The response from the origin will then be sent to the upper level ADC which looks at the destination port and forward the packet to the correct lower tier ADC. Hence, the ADCs at two levels will work in conjunction to provide transparent cache direction.

摘要： Systems and methods for consolidating metrics and statistics used for load balancing by a plurality of cores of a multi-core intermediary are disclosed. A timer operating on each packet engine of each core in a multi-core system may expire. A consolidator may store, responsive to expiration of the timer, a set of counter values from each of the packet engines to a first storage location. The consolidator may send to each packet engine a message to update the set of counter values. The consolidator may, upon completion of updating the set of counter values by the packet engines, send a second message to the packet engines that includes a consolidated set of counter values determined based on the updated set of values from each packet engine. Each packet engine may establish settings and parameters for load balancing based on the consolidated set of counter values.

摘要： The present solution is directed to providing, transparently and seamlessly to any client or server, layer 2 redirection of client requests to any services of a device deployed in parallel to an intermediary device An intermediary device deployed between the client and the server may intercept a client request and check if the request is to be processed by a service provided by one of the devices deployed in parallel with the intermediary device. The service may be any type and form of service or feature for processing, checking or modifying the request, including a firewall, a cache server, a encryption/decryption engine, a security device, an authentication device, an authorization device or any other type and form of service or device described herein. The intermediary device may select the machine to process the request and use layer 2 redirection to the machine. The intermediary device may change a Media Access Control (MAC) address of a destination of the request to a MAC address of the selected machine. Once the selected machine processes the request, the intermediary device may receive from this machine a response to processing the request. The intermediary device may then continue processing the request of the client responsive to the response from the machine or in response to identifying that the response to the request is from that particular selected machine. The forwarding to and processing by the parallel deployed machine may be performed seamlessly and transparently to the server and/or client.

摘要： The present invention is directed towards systems and methods for aggregating and providing statistics from cores of a multi-core system intermediary between one or more clients and servers. The system may maintain in shared memory a global device number for each core of the multi-core system. The system may provide a thread for each core of the multi-core system to gather data from the corresponding core. A first thread may generate aggregated statistics from a corresponding core by parsing the gathered data from the corresponding core. The first thread may transfer the generated statistics to a statistics log according to a schedule. The system may adaptively reschedule the transfer by monitoring the operation of each computing thread. Responsive to a request from a client, an agent of the client may obtain statistics from the statistics log.

摘要： The present disclosure presents systems and methods for maintaining original source and destination IP addresses of a request while performing intermediary cache redirection. An intermediary receives a request from a client destined to a server identifying a client IP address as a source IP address and a server IP address as a destination IP address. The intermediary transmits the request to a cache server, the request maintaining original IP addresses and identifying a MAC address of the cache server as the destination MAC address. The intermediary receives the request from the cache server responsive to a cache miss, the received request maintaining the original source and destination IP addresses. The intermediary identifying that the third request is coming from the cache server via one or more data link layer properties of the third transport layer connection. The intermediary transmits to the server the request identifying the client IP address as the source IP address and the server IP address as the destination IP address.
