Abstract: I/O board of a VXLAN switch removes VXLAN encapsulation from a packet, determines to perform layer 3 forwarding for the packet and sends the packet to a fabric board of the VXLAN switch. The fabric board determines to perform layer 3 forwarding for the packet, searches out a layer 3 entry matching a destination IP address of the packet from a local layer 3 table, modifies a source MAC address of the packet into a gateway MAC address of the VXLAN switch, modifies a destination MAC address of the packet into a destination MAC address in the layer 3 entry, and when an egress port in the layer 3 entry is a VLAN port, sends the modified packet to an I/O board associated with the egress port. The I/O board associated with the egress port forwards the packet to a VLAN via the egress port in the layer 3 entry.

Abstract: Satellite communication methods and payloads are described. An imbalance in uplink and downlink availability may be mitigated through digitizing uplink spectrum, extracting guard band channels, and grouping the guard band channels to create a composite channel. The composite channel is converted to analog and RF up-converted, amplified, and multiplexed with other downlink analog channels before being transmitted to Earth. The guard bands may be from the same band of spectrum or different bands of spectrum, such as C band, Ka band, Ku band, etc. A satellite payload is described with dual output multiplexers having partially overlapping channels and a dual feed configuration. In one downlink implementation, unused regional band spectrum may be dynamically allocated to a spot beam. In one uplink implementation, regional band spectrum may be shared by a spot beam using spatial separation of the regional uplink location from the spot beam coverage area and digital cancellation techniques.
