LookupLocalGridRoute
LookupLocalGridRoute — Click element;
LookupLocalGridRoute(ETH, IP, GenericGridRouteTable, KEYWORDS)
Ports: 2 inputs, 4 outputs
Processing: push
Forward packets according to the tables accumulated by the GenericGridRouteTable element. MAC-ADDRESS and IP-ADDRESS are the local machine's addresses.
Input 0 is from the device, output 0 is to the device. Both should be GRID_NBR_ENCAP packets with MAC headers. Output packets have their paint annotation set to the output interface number, e.g. for use with PaintSwitch.
Input 1 is down from higher level protocols, output 1 is is up to higher level protocols. The format of both is IP packets.
Output 2 pushes out packets that LookupLocalGridRoute doesn't know what to do with (we don't know have a route with a next hop), but are still valid. e.g. to be sent to geographic forwarding. These packets are GRID_NBR_ENCAP packets with MAC headers.
Output 3 is the error output; it pushes out packets that are bad: e.g., Grid protocol packets with an unknown type.
Keywords are:
- GWI — GridGatewayInfo element. If provided, and indicates this node is a gateway, send incoming packets for the generic gateway address to output 1.
- LOG — GridGenericLogger element. Object to log events to.
- LT — LinkTracker element. If provided, used to obtain link stats for route callbacks. Confused? Me too!
