Abstract: Some embodiments of the invention provide a novel method of tunneling data packets. The method establishes a tunnel between a first forwarding element and a second forwarding element. For each data packet directed to the second forwarding element from the first forwarding element, the method encapsulates the data packet with a header that includes a tunnel option. The method then sends the data packet from the first forwarding element to the second forwarding element through the established tunnel. In some embodiments, the data packet is encapsulated using a protocol that is adapted to change with different control plane implementations and the implementations' varying needs for metadata.

Abstract: A communication apparatus with a directional antenna, determines, for each of receivers, transmitter antenna directivities with each of which it is possible to transmit a test signal to the receiver as a partner receiver with a main lobe; determines, as a monitor receiver, for each of the determined directivities, if the test signal is transmitted with the directivity, a receiver capable of receiving the test signal by a side lobe appended to the main lobe; decides, based on reception quality in the partner receiver by the main lobe and reception quality in the monitor receiver by the side lobe, a transmitter antenna directivity, and a partner receiver and monitor receiver as reception targets of the data out of the receivers; and transmits the data to the decided partner receiver and monitor receiver with the decided directivity.

Abstract: A system transports a plurality of UDP datagrams from a sending application to a receiving application by creating a TCP tunnel between a TCP sending-end and a TCP receiving-end, encapsulating the datagrams in TCP packets at the TCP transmitting-end, transmitting the TCP packets via the TCP tunnel to the TCP receiving-end over a network using a TCP/IP protocol, and extracting the datagrams from the TCP packet and forwarding the extracted datagrams to the receiving application. The TCP tunnel may provide the same delay and responsiveness as UDP protocol. The TCP receiving-end may detect when a packet is missing and request retransmission when a packet is missing, so that the TCP sending-end retransmits the missing packets. The transmitting of TCP packets to the TCP receiving-end continues when the receiving-end detects a missing packet, so that there is no lag in the forwarding of the extracted datagrams. Retransmitted packets may be discarded.

Abstract: Disclosed herein are systems and methods for automatically grouping, authenticating, and provisioning access points using cloud-based management of wireless-local-area-network (WLAN) infrastructure. In an embodiment, a given site has a master access point that is manually configured with an organization-and-site-specific master-access-point configuration for providing service in a WLAN. Additional access points installed for operation transmit self-identifying messages to neighboring access points. Each access point compiles information about its neighbor access points in access-point neighbor lists. The access-point neighbor lists are received and used by a cloud-based WLAN-management service to identify the associated master access point and to provision unauthenticated access points using the correct organization-and-site-specific master-access-point configuration.
