application etc can be used for traffic classification. Generally the classification
standards are encapsulated in the header of the packets. The packet content is seldom
used as the classification standard.
2.1.3 Packet Filter
Packet filter is to filter traffic. For example, the operation “deny” discards the traffic that
is matched with a traffic classification rule, while allowing other traffic to pass through.
With the complex traffic classification rules, Ethernet Switches enable the filtering of
various information carried in Layer 2 traffic to discards the useless, unreliable or
doubtful traffic, thereby enhancing the network security.
The two key steps of realizing the frame filtering are as follows.
Step 1: Classify the ingress traffic according to the classification rule;
Step 2: Filter the classified traffic, i.e. the “deny” operation.
2.1.4 Traffic Policing
In order to deliver better service with the limited network resources, QoS monitors the
traffic of the specific user on the ingress, so that it can make a better use of the
assigned resource.
2.1.5 Bandwidth Assurance
Through the traffic reservation, a minimum bandwidth is reserved for the specified
traffic flow. Even when the network congestion occurs, the QoS requirements such as
packet dropping ratio, delay and jitter can also be satisfied at a certain degree.
2.1.6 Port traffic limit
The port traffic limit is the port-based traffic limit used for limiting the general speed of
packet output on the port.
2.1.7 Redirection
You can specify a new port to forward the packets according to your requirements on
the QoS policy.
