1 The bandwidth actually required in the LAN, for example, may be considerably higher. Here are some relevant factors:
– Data Link Layer used: Ethernet (with or without VLAN), PPP, Frame Relay ...
– Protocols with/without compression: RTP, UDP, IP
– Security: VPN tunnel ...
– Redundancy: For example T.38
– Packaging: the number of samples that are transported per package.
