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: A networking environment includes a first node and a second node configured as Ethernet Virtual Private Networking (EVPN) peers on an EVPN subnet that is coupled to a Layer 3 VPN over a core network. The first node receives a first multicast join request from a third node in the core network, the first multicast join request including a source address and multicast group address of a source of a multicast stream. The first node determines that the source address and the multicast group address for the source are behind the EVPN subnet at the second node. The first node sends to the second node, a control plane join request message that includes a receiver identifier that identifies the third node as a receiver of the multicast stream, the receiver identifier enabling the second node to forward the multicast stream directly into the core network to the third node.

Abstract: Some embodiments provide a method for forwarding data messages between edge nodes that perform stateful processing on flows between a logical network and an external network. At a particular edge node, the method receives a data message belonging to a flow. The edge nodes use a deterministic algorithm to select one of the edge nodes to perform processing for each flow. The method identifies a first edge node to perform processing for the flow in a previous configuration and a second edge node to perform processing for the flow in a new configuration according to the algorithm. When the first and second edge nodes are different, the method uses a probabilistic filter and a stateful connection tracker to determine whether the flow existed prior to a particular time. When the flow did not exist prior to that time, the method selects the second edge node for the received data message.

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: In one embodiment, associated differential processing of decapsulated packets is performed using Service Function Instances (SFIs) identified by Service Function Values (SFVs) derived from their encapsulating transport packets. By using different SFVs associated with different processing policies within a same processing context, one embodiment performs differential processing of streams of packets (arriving in transport packets) as identified by the particular SFV obtained from each particular transport packet. In other words, the processing policy identifies processing performed on the corresponding decapsulated original packet, not processing of the transport packet. Thus, if the original packet is an Internet Protocol (IP) packet, the SFI identifies Layer 3 processing that is performed on the original IP packet. Additionally, one embodiment uses a route advertising protocol (e.g., Border Gateway Protocol) to distribute associations between different SFVs and different addresses in a processing context (e.
