Description
Management of Network Bandwidth
The CISCO1721 Cisco 10/100BaseT Modular Router can be managed to control the bandwidth usage on a network through the use of Quality of Service (QoS) policies, access control lists (ACLs), traffic shaping and policing.
QoS policies allow you to set specific bandwidth limits for different types of network traffic, such as video or voice. This ensures that critical traffic has enough bandwidth, while also preventing bandwidth-intensive applications from consuming too much bandwidth and causing delays for other users.
ACLs can be used to limit the amount of traffic that can enter or leave a specific interface, which can help to control bandwidth usage. Traffic shaping and policing can also be used to control the rate at which traffic is sent or received, which can help to prevent network congestion.
Additionally, Cisco IOS commands can be used to monitor the router’s performance and usage of bandwidth, which can help to identify any issues or bottlenecks that may be affecting network performance. It is also recommended to keep the router’s firmware updated to fix any bugs that might be causing issues with bandwidth management.
Features and Benefits
The CISCO1721 Cisco 10/100BaseT Modular Router is a device that is designed to provide routing capabilities for small to medium-sized networks. It has a number of features and benefits that make it a popular choice for network administrators. Some of these include:
- 10/100BaseT Ethernet connectivity: The CISCO1721 has 10/100BaseT Ethernet ports, which allows it to support fast data transfer speeds and handle heavy network traffic.
- Integrated VPN support: The router has built-in support for Virtual Private Network (VPN) connections, which allows remote users to securely connect to the network.
- Quality of Service (QoS) support: The router includes features that allow you to prioritize different types of network traffic and ensure that critical traffic, such as voice and video, is given priority over less important traffic.
- Advanced security features: The router includes a number of security features, such as firewalls and access controls, that help to protect the network from unauthorized access and attacks.
- Easy to manage: The router is easy to set up and manage using a web-based interface or Cisco IOS commands.
- Modularity: The router has modular design that allows for easy upgrade and expansion of interfaces.
- Cost-effective: The CISCO1721 is a cost-effective solution for small to medium-sized networks.
Quality of Service (QoS) Features
The CISCO1721 Cisco 10/100BaseT Modular Router includes several Quality of Service (QoS) features that allow network administrators to prioritize different types of network traffic and ensure that critical traffic, such as voice and video, is given priority over less important traffic. Some of the QoS features of the CISCO1721 include:
- Traffic classification: The router can classify traffic based on various criteria, such as IP address, port number, and protocol.
- Priority queuing: The router can use priority queuing to ensure that high-priority traffic is sent before lower-priority traffic.
- Weighted Fair Queuing: This is a type of queuing technique that helps to prevent network congestion by allocating bandwidth based on the priority of each type of traffic.
- Class-based Weighted Fair Queuing (CBWFQ): This is an advanced type of queuing technique that allows for more granular control over bandwidth allocation by classifying traffic into different classes and assigning different weights to each class.
- Low Latency Queuing (LLQ): This is a technique that provides low-latency and prioritized treatment to specific types of traffic, such as voice and video, to ensure that they are delivered with minimal delay.
- Bandwidth Limiting: The router can be configured to limit the amount of bandwidth that can be used by specific types of traffic, which can help to prevent network congestion.
These QoS features can help to ensure that critical traffic, such as voice and video, is given priority over less important traffic, and that network resources are used efficiently and effectively. This can improve the overall performance and reliability of the network for users.
