ABSTRACT:
The ad-hoc router enables a decentralized IP routing network (mobile of fixed) amongst a set of network devices, and can offer quality of services for voice, video and data applications. The ad-hoc router is divided into a receiving, control/management processing, IP datapath/routing, randomizer, scheduler and transmission blocks. The IP datapath/routing block provides, in addition to the standard datapath routing functionality, per packet labels that uniquely identify the source device of the packet in the network. The scheduler maintains a plurality of QoS queues, which are then dequeued with a WFQ scheduler, which can be based on standard technology or a simplified low-cost implementation. The randomizer uses the labels to route the packets to a queue such that all packets from the source device, indicated by the label, enter the same queue. For greater security, the randomizer uses a random mapping function that is re-computed periodically.
