Routers

Routers mainly forwards data packages between computer networks. The router tables decide which paths to forward current packages. Typically routers do not involved in CCA.

Control

How to manage router tables:

• Static and dynamic routes are stored in Routing Information Base
• Build a router table
• Update a router table
• Classical algorithms: Bellmen-ford, Dijkstra, etc

Forwarding

• The router forwards data packets between incoming and outgoing interface connections by reading header in packets.
• How to deal with the situation when packets arrive at a rate higher than the router can process.

Note

Same question as with Links, where/what is the receive buffer and how are packets dropped/taken out of the buffer?
