In an approach to managing a load balancer cluster, one or more computer processors receive a packet comprising a source IP address of the packet. The one or more computer processors determine whether there is a record comprising the source IP address of the packet either in the load balancer or in the assistant. The one or more computer processors, responsive to determining there is no such record in the load balancer and there is the record in the assistant, obtain the record from the assistant, the record also comprising information of a first server in a server cluster and the first server being referred to as a destination server for any packet from the source IP address. The one or more computer processors send the packet to the first server.

Management for a load balancer cluster

A load balancer system having multiple load balancer machines working in parallel. At any given time, one of the load balancer machines is assigned to act as the current distributor that distributes web client communications and/or requests to the other load balancer machines in the load balancer system. However, these web client communications and/or requests are directed to a distributor module on all of the active, parallel load balancer machines in the system (for example, by the expedient of a common virtual IP address for layer 3/4 communications) in case the currently active distributor fails and one of the other active load balancer machines suddenly needs to take on the distributor role. In this way, web client communications are not lost when the current distributor machine fails.

Dynamic distributor selection for network load balancing

An approach is provided in which an information handling system receives, at a network virtualization edge (NVE), a set of Diffserv parameters comprising at least one classifier parameter, at least one meter parameter, at least one marker parameter, and at least one shaper/dropper parameter. The NVE performs a deep inspection on a plurality of data packets to classify the plurality of data packets at one or more classification levels. In turn, the NVE passes the set of Diffserv parameters and the one or more classification levels to underlay switch hardware.

Differentiated services for protocol suitable network virtualization overlays

An approach is provided in which an information handling system matches packet properties of an egress data packet to a classification rule corresponding to differentiated services (DiffServ) parameters. The information handling system encapsulates the egress data packet with a network virtualization overlay header that includes a DiffServ classification identifier corresponding to the DiffServ classification rule. In turn, the information handling system sends the encapsulated egress data packet to a downstream network component.
