Abstract: The present invention is directed towards systems and methods for monitoring services in a multi-core system. The systems and methods distribute the monitors for a service and the ownership of a service across the cores of the multi-core device. The greater resources of the multi-core device process the workload of the monitors for the services and the workload for monitoring the states of the services more efficiently than a single packet engine on a core.

Abstract: Described herein are systems and methods for improving networked communication systems by transforming IP addresses. In particular, an intermediary device disposed in a network between a plurality of clients and a plurality of servers can receive a request for a service offered at a specified domain name. The appliance can also receive a DNS-resolved primary address for a server associated with the domain name, and transform the primary address to a secondary address for the server. The address transformation can be done by the intermediary to prevent service interruption between a client and server due, for example, to server maintenance.

Abstract: The present solution provides a spillover management technique for virtual servers of an appliance based on health. Using a health based spillover technique, a network appliance may direct requests to a backup or second virtual server upon determining that a predetermined percentage of services being load balanced are down. In this manner, the spillover will occur based on a user controlled determination of a level of services being down to the number of services enabled. Instead of waiting for a last service of a virtual server to be marked down to spillover to another virtual server, the spillover may occur based on a user specified percentage. For example, the appliance may spillover from one virtual server to another virtual server when the number of services marked down relative to the number of enabled services falls below a specified percentage.
