Videoconferencing Performance Enhancement for Branch Users

C.

The company is experiencing issues with videoconferencing, which suggests that the network is not providing sufficient bandwidth for real-time traffic. To improve the performance of these applications, the company needs to ensure that there is adequate bandwidth available and that traffic is prioritized to avoid delays, jitter, and dropped frames.

Out of the given options, the best choice for improving performance for videoconferencing is Quality of Service (QoS). QoS is a set of networking technologies and protocols that prioritize certain types of network traffic over others. With QoS, the network can be configured to prioritize real-time traffic like videoconferencing, VoIP, and streaming media over less critical traffic like file transfers and email.

QoS can be implemented using different mechanisms, including traffic classification, traffic shaping, and traffic policing. Traffic classification is the process of identifying different types of traffic on the network, such as voice, video, and data, and assigning them different priority levels. Traffic shaping is the process of regulating the flow of traffic to prevent congestion and ensure that high-priority traffic gets the necessary bandwidth. Traffic policing is the process of enforcing traffic policies to ensure that network traffic conforms to predefined rules and limits.

Link Aggregation Control Protocol (LACP) is a protocol used to bundle multiple physical links into a single logical link for higher bandwidth and redundancy. While LACP can improve performance and availability, it is not directly related to the issue of videoconferencing performance.

Dynamic routing is a routing protocol that enables routers to exchange routing information and dynamically adjust their routes in response to network changes. While dynamic routing can improve network efficiency and availability, it is not directly related to the issue of videoconferencing performance.

Network load balancing is a technique used to distribute network traffic across multiple servers or network devices for higher availability and performance. While load balancing can improve performance, it is not directly related to the issue of videoconferencing performance.

Static IP addresses are fixed IP addresses assigned to devices on the network, rather than dynamically assigned by a DHCP server. While static IP addresses can be useful for managing and securing network devices, they are not directly related to the issue of videoconferencing performance.

In summary, the most likely solution to improve performance for videoconferencing is to configure Quality of Service (QoS) to prioritize real-time traffic over other types of network traffic.
