Abstract
An embodiment of the present invention includes a fax communication system for communicating fax information between a first fax machine having error correction capability and a second fax machine. The first and second fax machines are coupled to communicate with one another across a packet switching network. A network device is coupled to received fax information from the first fax machine and accumulates a portion of the fax information and stalls the second fax machine while accumulating the fax information portion until the latter is transmitted to the second fax machine free of errors across the packet switching network. Accordingly, information traffic across the packet switching network is decreased thereby avoiding a network avalanche effect.
