Class topic

Post 1. BRAS feature

BRAS is short for broadband remote access server, and it's used as an access gateway that functions as a bridge between a broadband access network and a backbone network, providing basic access and management functions...More

Post 2. Clock Synchronization

On a digital communication network, a sender places a pulse signal in a specific timeslot for transmission. A receiver needs to extract this pulse signal from this specific timeslot to ensure that the sender and receiver communicate properly. The clocks on the sender and receiver must also be synchronized to ensure smooth communication. Clock synchronization enables the clocks on the sender and receiver to be synchronized...More

Post 3. HoVPN and H-VPN

Currently, hierarchical architectures are used in most networking designs. To deploy VPN functions in a hierarchical architecture, a BGP/MPLS IP VPN must use a hierarchical model instead of a plane model. As a result, the concept of HVPN is introduced...More

Post 4. PBR and Route Policies

Policy-based routing (PBR) selects routes based on a User-

defined policy. Route policies filter routes and modify route attributes, which change the paths through which network traffic Passes...More

Post 5. TWAMP

The Two-Way Active Measurement Protocol (TWAMP) is a technology that measures the round-trip performance of an IP network.TWAMP uses UDP packets to collect statistics about the delay, jitter, and packet loss rate. In addition, TWAMP intelligently separates session control and traffic measurement to provide high security...More
