Abstract: Systems and methods of network packet switching use a table representation of a trie data structure to identify a timestamp (TS) range (or time range) for a received packet based on the packet timestamp (TS). The trie data structure is programmed with a plurality of predetermined time ranges. Each node in the trie data structure corresponds to a TS prefix and is associated with a corresponding predetermined time range. A search engine in the network switch can use the packet TS as a key to traverse the trie data structure and thereby matching the packet TS to a predetermined time range according to a Longest Prefix Match (LPM) process. Provided with the TS ranges of the incoming packets, various applications and logic engines in the network switch can accordingly process the packets, such as determining a new destination IP address and performing channel switch accordingly.

Abstract: A packet forwarding network may include spine and leaf switches that forward network traffic between end hosts. The packet forwarding network may be implemented on multiple network racks in a rack-based system. A controller may control the underlying spine and leaf switches to form on-premise virtual private cloud (VPC) resources. In particular, the controller may form enterprise VPC (EVPC) tenants, each having a virtual router that performs routing between different segments within the corresponding EVPC tenant. The different segments may separately include web, application, and database servers, as end hosts. The controller may form a system VPC tenant having a virtual system router that performs routing between different EVPC tenants. A segment in an internal VPC tenant formed by the controller and/or an external VPC tenant formed by the controller may provide external network access for one or more of the EVPC tenants.

Abstract: A method of and network devices arranged for inquiring node device address information after commissioning of a network of communicatively interconnected node devices. A gateway device (2) broadcasts an inquiry message (MINQ) in the network, requesting each of the node devices (3, 4, 5) to transmit its node device address announce message (MANN), after a time delay (?t1; ?t.2) from receiving the inquiry message (MINQ). The gateway device (2) transmits an acknowledgement message (MACK) to the node device addressed in a received node device address announce message (MANN), indicating that the respective node device address announce message (MANN) is received by the gateway device (2). A node device (4) may retransmit its node device address announce message (MANN) until receipt of an acknowledgement message (MACK). Received address information is stored by the gateway device (2) for control and communication purposes of the nodes in the network.

Abstract: Methods and apparatus for providing quasi-licensed intra-cell spectrum reassignment. In one embodiment, the quasi-licensed spectrum utilizes 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum, and a “seamless” reassignment of wireless spectrum without disruption or loss of continuity to existing data sessions of the CBSD is provided via a pool of temporary RF carriers which act as substitutes for the currently allocated (granted) carriers. The served user devices (e.g., UEs) are instructed by the CBSD to migrate to a new “final” carrier via the substitutes, either directly or via one or more intermediary hops. In one variant, existing 3GPP signaling mechanisms between the UE and CBSD/eNodeB obviates any changes to extant UEs. Communications between the CBSD and its cognizant SAS/DP include new information objects which direct the CBSD to implement the handover functionality. In a further variant, inter-CBSD sector and frequency handovers are provided for using CBRS-plane and 3GPP signaling.

Abstract: Disclosed embodiments utilize a layer three and/or layer four protocol to collect physical layer properties along a multi-hop network path between a source node and a destination node. The use of a layer three or layer four protocol provides an ability to span multiple links or networks between the source node and destination node, while also collecting the physical layer properties. Once physical layer properties along a network path can be understood, decisions relating to the configuration of the network path and/or whether to communicate via the network path are improved.
