| 12. | The ZigBee network layer natively supports both routers to extend communication at the network level.
|
| 13. | My question is how can this be if they are both at the network layer?
|
| 14. | Vulnerabilities exist at network layers, however, that are not visible to a stateful firewall.
|
| 15. | The first commercial network layer encryption device was the Motorola Network Encryption System ( NES ).
|
| 16. | Hence some remedial measures should be taken by the network layer to avoid these kind of situations.
|
| 17. | It is typically measured at a reference point below the network layer and above the physical layer.
|
| 18. | Additionally, as with all IP-based protocols, IPsec can operate at the network layer.
|
| 19. | Convergence layer takes care of service dependent functionality between DLC and Network layer ( OSI 3 ).
|
| 20. | IGMP operates on the network layer, just the same as other network management protocols like ICMP.
