Abstract: The present solution is related to a method for distributing flows of network traffic across a plurality of packet processing engines executing on a corresponding core of a multi-core device. The method includes receiving, by a multi-core device intermediary to clients and servers, a packet of a first flow of network traffic between a client and server. The method also includes assigning, by a flow distributor of the multi-core device, the first flow of network traffic to a first core executing a packet processing engine and distributing the packet to this core. The flow distributor may distribute packets of another or second flow of traffic between another client and server to a second core executing a second packet processing engine. When a packet for the flow of traffic assigned to the first core is received, such as a third packet, the flow distributor distributes this packet to the first core.

Abstract: An apparatus, method and computer program product for efficiently pooling network client-server connections. The apparatus is implemented within an interface unit connecting a plurality of servers to the Internet, which is in turn connected to a plurality of clients. The method includes the steps of opening a connection between a first client and the interface unit; determining whether a connection between the interface unit and a server is finished being utilized by the first client; opening a connection between a second client and the interface unit; if no free connection is open between the interface unit and the server, then allowing the second client to access information on the server via the same connection utilized by the first client without waiting for the first client to initiate closing the connection; and delinking the connections between the first and second clients and the interface unit while keeping open the connection between the interface unit and the server.

Abstract: The present application is directed towards invalidating (also referred to as poisoning) ASDR table entries that are determined to be inaccurate because of changes to a multi-node system. For example, when a node leaves or enters a multi-node system, the ownership of the entries in the ASDR table can change thus invalidating cached and replica entries. More specifically, the system and methods disclosed herein include searching an ASDR table for cached entries responsive to the system determining the multi-node system has changed. After finding a cached entry, the system may determine if the entry should be poisoned. The decision to poison the entry may be responsive to the creation time of the entry, the time when the change to the multi-node system occurred, and in the case of a replica, the owner of the replica's position in a replication chain relative to source of the replica.

Abstract: 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.

Abstract: The present invention is directed towards systems and methods for using a distributed hash table to maintain the same configuration and resource persistency across a plurality of cores in a multi-core system. The distributed hash table includes a plurality of partitions, each partition being owned by a respective core of the multi-core system. A core may establish resources in the partition it owns. A core may request other cores to establish resources in the partitions they own and send resource information to the core. The core may locally cache the resource information.
