Computing devices in a network offer network services by transmitting and receiving network service packets. In one embodiment, the packet includes a network service rank and a network service code. Each computing device within the network receives a transmitted packet and validates the accompanying service code. If the service code is validated, the packet's accompanying offered network service's rank is evaluated against an existing network service's rank. If the offered network service's rank is greater than the existing network service's rank, then an existing network service is disabled, and the network service identified by the received packet is installed. Further, each computing device periodically transmits to the remaining computing devices a packet identifying the transmitting computing device's offered network service's rank and the transmitting computing device's service code.
