What is IP 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.

"In today’s economy, IP VPN have become the cornerstone of a new age in network communications. IP VPN solutions overcome the challenges to support the increasingly complex enterprise network and the need to integrate multiple data, voice and video applications on a single network. Through IP VPN solutions, the modern enterprise network can:

• 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.

Benefits

• Quality of Service (QoS) - allocates different bandwidth for different applications based on individual branch offices.
• Cost Effectiveness - links branch offices together without the hassle of building additional point to point leased lines.
• Guaranteed Bandwidth - assures performance and reliability by providing committed information rate, based on the needs to support mission critical applications.
• Secure Environment - builds permanent virtual circuit (PVC) between branches,protecting the entire environment against outside intrusion.
• World Class Support - provide 24 hours a day , 7 days a weeks monitoring and unsurprassed technical support.

    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

    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 report: monitor 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 report: monitor the variation in latency between POPs with 5 min interval and represent the performance in different time frame
