Series Industrial Switch Routers

Product Description

NOTE

The AR500 series support only CPCAR.

PKI

3 Product Characteristics

The public key infrastructure (PKI) is a system that generates public keys and digital certificates, and verifies identities of certificate subjects to ensure information security. PKI issues digital certificates that bind public keys to respective user identities by means of a certificate authority (CA).

NOTE

The AR500 series (except , AR502CG-L and AR502EGW-L) does not support PKI function.

AAA

The AR500&AR510&AR530&AR550&AR2500 supports Authentication, Authorization, and

Accounting (AAA).

l Authentication

Verifies users' identities.

l Authorization

Grants different rights for different users to restrict the services that can be used by users.

l Accounting

Records information about network service usage of users, including service type, start time, and traffic volume.

For details about security features, see Security Configuration Guide.

3.2.4 QoS

Traffic Policing

Traffic policing discards excess traffic to limit the traffic within a specified range and to protect network resources as well as the carriers' interests.

The AR500&AR510&AR530&AR550&AR2500 uses committed access rate (CAR) to perform traffic policing. They support dual-rate-three-color markers and precise bandwidth management.

Traffic Shaping

When the rate of an interface on a downstream device is slower than that of an interface on an upstream device or burst traffic occurs, traffic congestion may occur on the downstream device interface. Traffic shaping can be configured on the interface of an upstream device so that outgoing traffic is sent at even rates and congestion is avoided.

The AR500&AR510&AR530&AR550&AR2500 supports traffic shaping adaptation and level-3 traffic shaping. Three-level shapers include the flow queue shaper, subscriber queue shaper, and port queue shaper.
