2.3 Bandwidth Allocation
The SkyPilot system implements a synchronization of the 802.11 protocol. This
synchronization allows for the establishment of individual links between nodes utilizing a
unique timing and antenna combination. In addition, highly accurate traffic rate and jitter
control is enabled.
The initial release of the SkyPilot system provides rate control for subscriber traffic both
in the downstream (Gateway to CPE) and in the upstream (CPE to Gateway) direction.
The maximum rate downstream and upstream rate can be specified for each subscriber. In
conditions of over-subscription when the overall bandwidth demand is higher than the
system capacity, the individual subscriber data rates will be reduced proportionately. i.e.
a configured 2Mbps is reduced to 1.5Mbps while a configured 1Mbps rate is reduced to
750kbps.
See Section 4.2.4 for details of the subscriber rate configuration.
2.4 Networking
The SkyPilot system operates as a Layer 2 network. The GW1000 and SD1000 have an
Ethernet bridge. All upstream subscriber traffic is direct out the GW1000 Ethernet port
and to external switch or router.
The GW1000 and SD1000 implement a SNMPv2c agent. In addition, there is also a CLI
that may be access locally via a serial port or remotely via Telnet. In order to support
these interfaces, an IP address must be allocated. This allocation can be done dynamically
via DHCP or may be statically configured. See Section 4 for details.
