The present disclosure identifies topologies of a computer network where one network appliance may be configured as a master network appliance and where that master network appliance may communicate over a network communication interface with one or more slave network appliances. Computer networks of the present disclosure may include a switch and a firewall where the switch may be coupled to several network appliances via different network communication interfaces.

Routing of communications to one or more processors performing one or more services according to a load balancing function

Systems and methods for routing communications to a platform service are provided. A message including payload data is received. The information in the payload data of the message is examined in order to determine the type of message. The message is then relayed to an appropriate platform service based on the type of message. Some embodiments assign numbers to the packets that make up the message.

Routing of communications to a platform service

A network appliance is described that can provide a variety of software services, including both platform services, such as access method services, and a load balancing service. A network may include a network appliance that both provides one or more platform services and acts as a load balancer. When two or more such appliances are used together, they can replace a substantial portion of a conventional network. For example, when a network appliance receives a client communication, its load balancer service can determine whether one of its own platform services will process the communication or forward the communication to another network appliance for processing. Moreover, if the load balancing service of a network appliance fails, another network appliance can provide load balancing. Similarly, if another service of a network appliance fails, then the network appliance may continue to provide load balancing but forward communications requiring the failed service to another network appliance for processing.
