Virtual LAN system

TL;DR: In this paper, an electronic device for emulating other electronic devices comprising an interface (6) for enabling communication within a network (11), an embedded emulation system (10) comprising transmission emulation means (9) for creating messages to be sent via the interface, said messages having as sender address the address of the second electronic device (12).

TL;DR: In this article, a system and method for extending a communication protocol by constructing a top level message, constructing a first level extension message, and embedding the first-level extension message in a data component of the top-level message is presented.

TL;DR: In this paper, a video server consists of an interface unit, memory units, a line concentrator, and decoders to decode a packetized data file transmitted from the line concentrators and output video data.

TL;DR: In this article, the information processing apparatus includes a storing unit and a transferring unit, where the storing unit stores the first association information, in which address information on a VM connected to a port is associated with information indicating a logical network, and second association information in which information indicating the port was associated with the logical network to which the VM connected with the port belongs.

TL;DR: In this paper, a configuration policy maintenance circuit is provided for storing policies related to reconfiguring the at least one switching device upon the modification of the topology, and a policy evaluation circuit was provided for determining which end-station and ports should be grouped together in a first manner.

TL;DR: In this paper, the authors present a method for establishing restricted broadcast groups in a switched network, which assigns different virtual LAN identifiers (VLAN-IDs) to different subsets of associated end systems or access ports.

TL;DR: In this paper, a method for establishing and maintaining virtual network domains in a segmented computer network having a first domain and a second domain is presented, where a packet having the first endstation as a source is received by the first port of the first switching fabric circuit, and a destination for the packet is determined.

TL;DR: In this article, a broadband intelligent network (50) employs an ATM switch or other fast-packet switch in a fiber optic, fastpacket communication system, which is directly coupled through one of its ports to a network service control point (61) for the implementation of requested services without the use of an intermediate common channel signaling system.
