Converged Network features: |
- Call Control - Voice Messaging - Mobility - Automated attendant |
|
|
Advantages of Converged Network |
- One Physical network to install/manage. - Cheaper, easier Management Interface - Integrates voice and video call functions |
|
|
Three Tier hierarchical design layers: |
- Core - Distribution - Access |
|
|
Two Tier hierarchical design layers: |
- Core/Distribution (collapsed into one) - Access - Good for smaller areas - aka. Collapsed Core Network Design |
|
|
Switched LAN additional features over Layer 2 |
- QoS - Security - Wireless network support - Support for new tech (eg. IP Telephony) |
|
|
Modular vs. Fixed config switches |
Fixed switches only support the features and ports it came with. Modulars come in different Chassis that support other modular line cards (that contain ports) |
|
|
Stackable Config Switches |
- Switches interconnected via cable. The entire group of switches act as one large Switch. Provides fault-tolerance for Fixed config switches. - Cheaper than Modular switch |
|
|
Ethernet frames are forwarded based on destination MAC address (T/F)? |
True |
|
|
CAM table |
Content Addressable Memory table. Basically MAC address table. |
|
|
Populating MAC table |
Populated dynamically when a frame is received and successfully sent to a destination device. The source and destination MAC is recorded. |
|
|
Store and Forward Switching |
Frame forwarding method, where Switch receives entire frame and checks for errors before forwarding frame ahead. |
|
|
Cut-Through Forward Switching |
Frame forwarding method, Switch reads destination MAC and egress port and immediately forwards frame. |
|
|
Fragment Free Switching |
Modified Cut-Through method, where first 64 bytes (up to Collision header) of frame are analysed to ensure no fragmentation occurred before forwarding the frame. |
