Abstract: A method for enabling autonegotiation over an interface for which no autonegotiation standard exists comprises establishing network communication between a first network device and a second network device over a communication link. The first network device includes a first media access controller (MAC) associated with a communication port coupled to the communication link and a second MAC positioned between the first MAC and the communication port, and the second MAC operates as a proxy MAC for the first MAC. The first MAC outputs an outbound data communication to the communication port at a first communication rate. The proxy MAC intercepts the outbound data communication. The proxy MAC then outputs the outbound data communication to the communication port at a second communication rate different from the first communication rate.

Abstract: In general, techniques are described in which a plurality of network switches automatically configure themselves to operate as a single virtual network switch. A virtual switch is a collection of individual switch devices that operate like as single network switch. As described herein, network switches in a network that are capable of participating in a virtual switch may automatically discover one another. The participating network switches may then elect one of the participating switches as a master switch. The master switch may generate forwarding information and store the forwarding information in the participating switches, including the master switch. The forwarding information causes the participating switches to act like a single network switch.

Abstract: A method of communicating in a communication system and the communication system are provided. The communication system comprises at least one imaging station with multiple network interfaces. Each network interface of the imaging station is identified with a network address. The method comprises steps of selecting a first network interface available for communication in an imaging station and configuring the imaging station to communicate via the first network interface. The method further comprises a step of communicating at least one imaging data from the imaging station via the first network interface.

Abstract: A method is provided to reduce multicast traffic by snooping IGMP control packets on a packet-forwarding device. A multicast traffic reducer includes an IGMP proxy, which operates in conjunction with an IGMP snooper to intercept selected IGMP control packets and generate proxy IGMP control packets in their place. The IGMP proxy may include an IGMP query batcher to consolidate IGMP queries to multicast host groups, an IGMP query responder to consolidate host responses to the IGMP queries to multicast host groups, and/or an IGMP leave forwarder to manage host IGMP leave packets. The IGMP proxy consolidates or discards host-generated IGMP control packets and timely generates IGMP proxy control packets in their place. The IGMP proxy further includes an IGMP layer-2 query generator to initiate IGMP queries for a layer-2 router multicast application.
