Advanced features such as Quality of Service (QoS)
The Cisco Secure Hardened Router C819H-K9 has advanced Quality of Service (QoS) features that allow for efficient and effective management of network bandwidth. These features include:
- Class-Based Weighted Fair Queuing (CBWFQ) – This feature allows for the allocation of bandwidth to different traffic classes based on their priority level. This ensures that critical traffic, such as voice and video, is given priority over less critical traffic, such as email and web browsing.
- Low Latency Queuing (LLQ) – This feature allows for the prioritization of real-time traffic, such as voice and video, to reduce delays and jitter.
- Policing and shaping – These features allow for the control and management of traffic bandwidth by specifying a maximum rate for certain traffic classes. This ensures that bandwidth is not exceeded and prevents congestion on the network.
- Multi-Field Classifier – This feature allows for the classification of traffic based on multiple fields, such as IP address, protocol, and port number, providing more granular control over traffic management.
- Hierarchical Quality of Service (HQoS) – This feature allows for the creation of a hierarchical QoS structure, with different levels of priority and bandwidth allocation, providing more efficient and effective management of network resources.
