What is Virtual Private Network (VPN)?

An Internet Protocol Virtual Private Network (IP VPN) is a routed link between two or more points across a shared network infrastructure with various degrees of security. IP VPN offers an enterprise-class scalability and reachability across multiple IP-based infrastructures, along with the performance and security characteristics that traditionally found only in dedicated private environments.


Grow and continuously connect geographically dispersed branch offices, teleworkers, business partners, and customers to corporate network resources over secure, reliable, and economical flexible connections.
Increase the network traffic resulting from increase business use of networked applications.
Adapt new network applications, such as IP telephony and e-collaboration, that can reduce cost, improve productivity, and enable new levels of communication efficiency with various service performance requirement.



  Customer Access Port
  The Access Port is used to connect the corresponding last mile from customer site to the access router of local POP. For each type of access port, it can be Premium or Standard Port.
    Premium Access Port
    Allocate dedicated bandwidth for connection from PE to CE router through the last mile.
    Standard Access Port
    Presume shared bandwidth access from PE to CE router.
    Leased Line Premium Access Port: Nx64k, T1, E1, DS3
    SDH Premium Access Port: Nx2M, STM-1, 4, 16
    ATM Premium Access Port: ATM
    Ethernet Premium Access Port: Ethernet, Fast Ethernet, Gigabit Ethernet
    XDSL Access Port: Symmetric, Asymmetric
  For each Customer Access Port, the customer can subscribe different combination of Service Class options catering for different priority and performance of its application use.
    5 Service Classes
    Diamond: Real-Time Voice
    Platinum:Real-Time applications

  Online Network Report   

It is a network reporting tool to show the utilization and performance of the network.

With the network statistics, the customer can manage and plan for network upgrade easily.


MRTG report: monitor the bandwidth utilization per port with 5 min interval and represent the performance in different time frame



Latency reportmonitor the POP-to-POP roundtrip delay with 5 min interval and represent the performance in different time frame



Packet Loss report: monitor the packet delivery performance from POP-to-POP with 5 min interval and represent the performance in different time frame



Jitter reportmonitor the variation in latency between POPs with 5 min interval and represent the performance in different time frame
