Study Notes
Selecting Switches for Hierarchical Networks
- Scalability is crucial; a switch must accommodate growing network needs without requiring frequent replacements.
- Switch performance including speed, throughput, and latency are vital to ensuring efficient data flow in a hierarchical structure.
- Management features such as VLAN support, traffic prioritization, and monitoring are important considerations when choosing a switch.
Evolving Network Requirements
- Companies require adaptable networks to support new technologies, applications, and fluctuating user demands.
- Agility in network design allows for timely upgrades and integration of emerging technologies, enhancing overall business resilience.
Considerations for Hierarchical Network Switches
- Layer 2 and Layer 3 features must be evaluated; switches could operate at different OSI layers depending on the architecture.
- Power over Ethernet (PoE) capabilities may be needed for supporting devices like IP cameras and VoIP phones.
- Reliability and redundancy features such as stacking and failover mechanisms are essential for maintaining service continuity.
Devices Added During Business Growth
- Routers may be introduced to improve connectivity between different network segments.
- Access points can help expand wireless coverage as the workforce increases.
- Network security appliances like firewalls and intrusion detection systems may become necessary for protecting sensitive data.
VoIP Impact on Network
- Transitioning to converged VoIP phone systems can significantly increase traffic, requiring enhanced bandwidth and quality of service considerations.
- VoIP allows multiple channels of communication, leading to a potential rise in call volume and data usage over the network.
Features in Switch Hardware Selection
- Support for advanced security features such as port security and network access control lists (ACLs) is increasingly important.
- Energy efficiency can also be a consideration in selecting switches to minimize operational costs and environmental impact.
Phone Systems and Network Traffic
- VoIP phone systems may add additional traffic to a network while replacing traditional analog telephone systems.
- Unified communications applications can further increase data throughput, necessitating higher performance in network switches.
Cisco Switch Platforms
- Cisco switch platforms cater to a variety of business sizes, from small to large enterprises, providing flexibility as business needs evolve.
- Their scalability and feature sets make them applicable for numerous industries, adapting to both small startups and established organizations.
