Abstract: In some embodiments, a system includes a set of servers, a set of switches within a switch fabric, and an optical device. The optical device is operatively coupled to the set of servers via a first set of optical fibers. Each server from the set of servers is associated with at least one wavelength from a set of wavelengths upon connection to the optical device. The optical device is operatively coupled to each switch from a set of switches via an optical fiber from a second set of optical fibers. The optical device, when operative, wavelength demultiplexes optical signals received from each switch from the set of switches, and sends, for each wavelength from the set of wavelengths, optical signals for that wavelength to the server from the set of servers.

Abstract: A mesh network of wired and/or wireless nodes is described in which a centralized controller provides seamless end-to-end service from the edge of the mesh network to mesh nodes located proximate to subscriber devices. The controller operates to provide a central configuration point for configuring forwarding planes of the mesh nodes of the mesh network, so as to set up transport data channels to transport traffic from the edge nodes via the mesh nodes to the subscriber devices.

Abstract: Dynamic control channel establishment for an access network is described in which a centralized controller provides seamless end-to-end service from a core-facing edge of a network to access nodes. For example, a method includes receiving, by the centralized controller, a discover message originating from a network node, which includes an intermediate node list that specifies a plurality of network nodes the discover message traversed from the network node to an edge node, determining, based on the plurality of nodes specified by the discover message, a path from the edge node to the network node, allocating each of a plurality of Multi-protocol Label Switching (MPLS) labels to a respective outgoing interface of each of the plurality of network nodes, and outputting one or more control messages for configuring the network node, wherein the control messages are encapsulated within a label stack comprising the allocated plurality of labels.

Abstract: A high-performance, scalable and drop-free data center switch fabric and infrastructure is described. The data center switch fabric may leverage low cost, off-the-shelf packet-based switching components (e.g., IP over Ethernet (IPoE)) and overlay forwarding technologies rather than proprietary switch fabric. In one example, host network accelerators (HNAs) are positioned between servers (e.g., virtual machines or dedicated servers) of the data center and an IPoE core network that provides point-to-point connectivity between the servers. The HNAs are hardware devices that embed virtual routers on one or more integrated circuits, where the virtual router are configured to extend the one or more virtual networks to the virtual machines and to seamlessly transport packets over the switch fabric using an overlay network. In other words, the HNAs provide hardware-based, seamless access interfaces to overlay technologies used for communicating packet flows through the core switching network of the data center.

Abstract: A first network client requests initiation of a data transfer with a second network client. An admission control facility (ACF) responds to the initiation request by performing admission analysis to determine whether to initiate the data transfer. The ACF sends one or more packets to the second network client. In response, the second network client sends acknowledgment packets back to the ACF. The ACF performs admission analysis based on the packets sent and the acknowledgment packets, and determines whether the data transfer should be initiated based on the analysis. The admission analysis may be based on a variety of factors, such as the average time to receive an acknowledgment for each packet, the variance of the time to receive an acknowledgment for each packet, a combination of these factors, or a combination of these and other factors.
