Anti-IP-defraud: Check whether the source address of MS
packets is the IP address that is assigned when the PDSN9660
activates the user. If not, the PDSN9660 discards the packets.
Anti-DDoS: TCP-SYN flood is a major DDoS attack. The
PDSN9660 can restrict the number of TCP SYN packets in a
specific period to prevent this DDoS attack.
Multiple security verification modes are provided for major
routing protocols such as OSPF, IS-IS, and RIP.
Multiple-level authorities management mode for operator
Pi interface redirection: The traffic between MSs in the same
PDSN9660 is redirected to a firewall.IPSec: It provides security measures such as high-quality
encryption and verification.

The packet control function (PCF)
chooses activated users in the PDSN pool
based on the round-robin algorithm. The PCF can detect the status of the
PDSN and switch over the user activation
paths in one to three seconds by running
ICMP ping and Trace route.
In the PDSN pool, the PDSNs works in
active/standby or load-sharing mode.
In the PDSN pool, the static and dynamic
routing protocols are used between the
PDSN and external routers to ensure the
connectivity of the user downstream link.
In the PDSN pool, the PDSNs can
provide the same service features.

Upgrading the client automatically
The client can be upgradedautomatically based on the serverversion, which is convenient for dailymaintenance.
Step 1: Upgrade the M2000 server.
Step 2: After detecting the versionchange of the M2000 server, the
M2000 clients automatically download
the new version from the M2000
server for automatic upgrade.
Upgrading the software of NEs
Download the software of the networkelements (NEs) and then upgrade theNEs.
The M2000 can upgrade the software ofmultiple NEs at the same time.
You can remotely control the upgrade.
The upgrade cannot affect the onlineservices.
