Abstract: Some embodiments provide a method for a software-defined wide area network (SD-WAN) connecting first and second sites, with the first site including an edge node and the second site including multiple forwarding hub nodes. At the edge node of the first site, the method receives a packet of a particular flow including a flow attribute. The method uses the flow attribute to identify a hub-selection rule from multiple hub-selection rules, each hub-selection rule identifying at least one forwarding hub node at the second site for receiving one or more flows from the first site, and at least one hub-selection rule identifying at least one forwarding hub node that is not identified by another hub-selection rule. The method uses the identified hub-selection rule to identify a forwarding hub node for the particular flow. The method then sends the packet from the edge node at the first site to the identified forwarding hub node at the second site.

Abstract: Various example embodiments for controlling reordering of packets in packet switched networks are presented herein. Various example embodiments for controlling reordering of packets in packet switched networks may be configured to control reordering of packets in packet switched networks based on control of reorderability of packets in packet switched networks. Various example embodiments for controlling reordering of packets in packet switched networks may be configured to control reorderability of packets in packet switched networks, and, thus, reordering of packets in packet switched networks, based on use of a reorderability indicator (RI). The RI for a packet is included in the packet to indicate reorderability of the packet, where the reorderability of the packet is indicative as to whether or not reordering of the packet is permitted. The RI may be included in a packet for controlling reorderability and, thus, reordering, of the packet as the packet traverses a network.

Abstract: A set of remote Virtual Extensible LAN (VxLAN) tunnel endpoints (VTEPs) and an ingress VTEP associated different Ethernet Segments (ESs) elect amongst themselves designated forwarder (DF) for forwarding broadcast, unknown-unicast, and multicast traffic (BUM) traffic by triggering an RFC 7432 election mechanism on each of the VTEPs. In embodiments, DF election involves exchanging configuration information, such as Type-4 routes for ESs via Border Gateway Protocol (BGP), without being confined to a particular ES that is local to all VTEPs, i.e., irrespective of local ES and internet identifiers. This allows performing targeted forwarding of BUM traffic to intended VTEPs which avoiding unnecessary ingress replication of BUM traffic in the ingress VTEP, thereby, saving hardware buffer resources and avoiding unnecessary flooding of frames to a set of non-forwarding egress VTEPs, ultimately, reducing the load on the egress VTEP and freeing up packet processing resources.

Abstract: In some embodiments, a method comprises: transmitting first data units from a source node to a destination node over a first path; receiving information about the availability of one or more second paths between the source and destination nodes; determining a cost associated with each of the one or more second paths; allocating a first number of second data units to the first path and a second number of second data units to the one or more second paths based on the determined costs; and transmitting the second data units from the source node to the destination node over the first path and/or the one or more second paths according to the allocation, wherein the first data units, the second data units, or both the first and second data units comprise network coded data.

Abstract: Instead of users (e.g., independent owners/operators of different satellites) having to calculate orbit determination for each satellite themselves, an orbit determination service automatically calculates the orbit determination (OD) based on a user request. The calculated OD can then be used by a satellite ground station service to determine appropriate orientations for a ground station antenna in order to communicate with the satellite. In some embodiments, the OD service uses information from the calculations of ODs for multiple satellites and users to update a model used in the OD calculation, for example, to provide a more accurate model for Earth's atmosphere to be applied in subsequent OD calculations. In some embodiments, the OD service uses a user-provided computer-aided drawing (CAD) file of the satellite to produce or tune models specific to the satellite, for example, to generate more accurate models for solar radiation pressure and ballistic drag.

Abstract: Techniques are presented herein for load-balancing a sequence of packets over multiple network paths on a per-packet basis. In one example, a first network node assigns sequence numbers to a sequence of packets and load-balances the sequence of packets on a per-packet basis over multiple network paths of a network to a second network node. The second network node buffers received packets that are received over the multiple network paths of the network from the first network node and re-orders the received packets according to sequence numbers of the received packets.

Abstract: A communication device assists location services by receiving a virtual boundary condition from the operating system. The virtual boundary condition is received by a wireless communication chipset (e.g., a Wi-Fi chipset) of the communication device. The Wi-Fi chipset measures one or more distances between the communication device and one or more wireless communication devices (e.g., Wi-Fi access points) using a wireless communication distance measuring protocol (e.g., Wi-Fi Fine timing measurement or FTM), determines that the virtual boundary condition has been satisfied by the one or more measured distances, and notifies the operating system that the virtual boundary condition has been satisfied by the one or more measured distances.

Abstract: A network device receives multi-destination packets from a first node and forwards at least a first of the multi-destination packets to another network device using a first multi-destination tree with respect to the network device. The network device detects that a link associated with the first multi-destination tree satisfies one or more criteria and, in response to detecting that the link satisfies the one or more criteria, selects a second multi-destination tree with respect to the network device. The network device forwards at least a second of the multi-destination packets to the other network device using the second multi-destination tree.

Abstract: Techniques for a scalable wireless network feature for maintaining communications between wireless devices accessing a facility are described herein. A virtual partition for each wireless virtual local area network (VLAN) of a plurality of VLANs may be maintained. A virtual partition is configured to process mapping requests from one or more wireless devices of a particular VLAN of the VLANs. A threshold may be maintained that is associated with roaming per second events by the one or more wireless devices of the facility. A new virtual partition for a new VLAN may be instantiated based on information from the one or more wireless devices indicating that the roaming per second events exceed the threshold. One or more components of an intermediate distribution frame may be updated with mapping data to utilize with new wireless devices accessing the facility and for communicating with the new virtual partition for the new VLAN.

The core identity may be stored in the header or payload of the packets. In an example embodiment, the second network determines the core for processing packet belonging to the same session.

Abstract: Example methods and computer systems for packet handling for active-active stateful service insertion are disclosed. One example may involve in response to detecting a first packet from a first active logical service router (SR), a computer system generating and storing state information that associates (a) the first active logical SR and (b) first tuple information specified by the first packet. The first active logical SR and a second active logical SR may be both associated with the service endpoint address and configured to operate in an active-active mode. In response to detecting the second packet from a destination responsive to the first packet, the computer system may select the first active logical SR over the second active logical SR based on the state information and second tuple information specified by the second packet; and send the second packet towards the first active logical SR for processing according to a stateful service.
