End-to-end delay is the time it takes a packet to travel across the network from source to destination. Delay jitter is the fluctuation of end-to-end delay from packet to the next packet.

End-to-end delay refers to the total time taken for a packet to travel from the source to the destination. Packet jitter, on the other hand, is the variation in delay between packets caused by network congestion, routing changes, or varying traffic patterns. In essence, end-to-end delay is the total time taken, while packet jitter measures the variability in that delay.
Packet Filtering:permits or denies traffic based onsource/destination IP addresses, or TCP/UDP port numbers usingAccess Control Lists (ACLs)Stateful Packet Inspection:Tracks TCP and UDP sessions in a flowtable, using the Adaptive Security Algorithm.
A network hub absconds with any stateful packet inspection (SPI), so it won't act as a firewall.
