Abstract: An overview of the characteristics and challenges of optical packet switching is given, illustrating its potential advantages within future nodes and networks, describing basic system functionalities. The opportunities introduced by the ACTS KEOPS project on all-optical packet-switching networks are highlighted, based partially on the outcome of the RACE ATMOS project, which is also considered in this article.

TL;DR: The author shows how the bandwidth available through the use of multiwavelength optical-fiber technology can be used to achieve novel large-capacity switching systems to address anticipated switching bottlenecks.
Abstract: The author shows how the bandwidth available through the use of multiwavelength optical-fiber technology can be used to achieve novel large-capacity switching systems to address anticipated switching bottlenecks. He does so by describing the features and network applications of a specific multiwavelength network, the Bellcore LAMBDANET packet switch. The discussion is then extended to a number of recent proposals for switching fabrics based on this new multiwavelength technology. The particular technologies he discusses are: the photonic knockout switch, a proposal similar to the concept of the LAMBDANET, but not requiring N receivers at each node; the FOX (fast optical cross-connect), an active wavelength routing approach; the ShuffleNet architecture; the HYPASS and BHYPASS switches; the coherent wavelength division lambda switch; and the Bellcore Star-Track multicast switch. >

TL;DR: Results show that the video quality can be substantially improved by utilizing the frame error information at UDP and application layer, and several maximal distance separable (MDS) code-based packet level error control coding schemes are proposed.
Abstract: Packet video will become a significant portion of emerging and future wireless/Internet traffic. However, network congestion and wireless channel error yields tremendous packet loss and degraded video quality. In this paper, we propose a new complete user datagram protocol (CUDP), which utilizes channel error information obtained from the physical and link layers to assist error recovery at the packet level. We propose several maximal distance separable (MDS) code-based packet level error control coding schemes and derive analytical formulas to estimate the equivalent video frame loss for different versions of user datagram protocol (UDP). We validate the proposed packet coding and CUDP protocol using MPEG-coded video under various Internet packet loss and wireless channel profiles. Theoretic and simulation results show that the video quality can be substantially improved by utilizing the frame error information at UDP and application layer.

TL;DR: In this paper, a switch that facilitates remote port mirroring is described, which can include an encapsulation mechanism and a forwarding mechanism, and can be configured to encapsulate a copy of a first packet in a second packet, thereby preserving header information.
Abstract: A switch that facilitates remote port mirroring is described. The switch can include an encapsulation mechanism and a forwarding mechanism. The encapsulation mechanism can be configured to encapsulate a copy of a first packet in a second packet, thereby preserving header information (e.g., a VLAN identifier and/or a TRILL header) of the first packet. The forwarding mechanism can be configured to forward the first packet using header information of the first packet, and forward the second packet using header information of the second packet. The second packet can be received at a destination switch which extracts the first packet from the second packet, and sends the first packet on a port which is coupled to a network analyzer.
