What is the function of the input buffer in Ethernet decentralized switching?
Queueing datagrams if they arrive faster than the forwarding rate into the switch fabric
What does the destination-based forwarding in Ethernet decentralized switching rely on?
Forwarding based only on the destination IP address
What technique is used to determine the forwarding table entry for a given destination address in Ethernet decentralized switching?
Longest prefix matching
What is the main purpose of the switching fabric in Ethernet decentralized switching?
Transferring packets from input buffer to appropriate output buffer
How is the switching rate defined in the context of Ethernet decentralized switching?
The rate at which packets can be transferred from inputs to outputs, often measured as a multiple of input/output line rate
When using Ethernet decentralized switching, what is the purpose of longest address prefix matching?
To find the forwarding table entry that matches the destination address
In generalized forwarding, what header field values are used to determine the output port?
Any set of header field values
What does the input port memory contain in Ethernet decentralized switching?
Forwarding table for determining output port using header field values
What happens when destination address ranges don't divide up nicely in Ethernet decentralized switching?
Longest prefix matching is used to find an appropriate range for the destination address
What does the forwarding table entry prioritize when using longest prefix matching in Ethernet decentralized switching?
The most specific matching range for the destination address
What is the function of the control plane in a network router?
Interacting with local control plane control agents remotely
What is the main function of the forwarding plane in a network router?
Moving packets from router’s input to appropriate router output using data plan
