Bog'liq Chapter 4 Network TopologiesHierarchical rings Hierarchical stars - Star topologies, can be implemented in hierarchical arrangements of multiple stars
- Hierarchical stars can be implemented as a single collision domain or segmented into multiple collision domains using switches, routers or bridges
Hierarchical stars Hierarchical combinations - Overall network performance can be enhanced by not force-fitting all the functional requirements of the LAN into a single solution
- Today’s high-end switching hubs enable you to mix multiple technologies
Hierarchical combinations WAN Topologies WAN Topologies - Peer-to-peer WANs
- Ring WANs
- Star WANs
- Full-mesh WANs
- Partial-mesh WANs
- Two-tiered
- Three-tiered
- Hybrids
Peer-to-peer topology - A peer-to-peer WAN can be developed using leased private lines or any other transmission facility
- This WAN topology is a relatively simple way of interconnecting a small number of sites
- Represents the least-cost solution for WANs that contain a small number of internetworked locations
Peer-to-peer - Advantage:
- It is inexpensive relative to other options
- Disadvantages:
- They don’t scale very well. As additional locations are introduced to the WAN, the number of hops between any given pair of locations remains highly inconsistent and has an upward trend
- An equipment or facility failure anywhere in a peer-to-peer WAN can split the WAN
