Virtual Private
Network
Service
(IPVPN/EVPN)

Product Details

Based on broadband IP network, the private line service of Telstra PBS virtual private network (VPN) uses MPLS (Multi-Protocol Label Switching) technology to build enterprise IP private network on private IP networks and realize multi-service broadband connection of data, audio and image. Combining differential services, traffic engineering and other related technologies, Telstra PBS can provide users with high quality services.

Virtual Private Network Applications

Audio telephone system

Through the establishment of audio gateway and telephone system, corporate headquarters and branches can use internal audio communication to minimise telephone bills.

ERP system

Ensure network quality and data privacy, and assist company’s internal service system to run efficiently.

Data application

Data transfer between private networks strengthens the communication between offices and enables more secure communications.

Video conference

Effectively utilising company’s existing business broadband resources and use multi-point video conferences to reduce communication costs.

Mail system

Build company’s internal mail system, so receiving and sending mails become more convenient and efficient.

Telstra PBS adopts flexible QoS (Quality of Service) to make sure services with high priority (audio and video) are transmitted first. When services with higher priority are not being utilised, the idle bandwidth can then be released for those services with lower priority.

Product Category

Virtual Private Network (Layer 3) (IPVPN)

Telstra PBS’s IPVPN license covers the whole of Mainland China (excluding Sinkiang and Tibet) and has the following advanced technical features:

  • Support 5 CoS (Class of Service)
  • Internet + IPSec access/backup
  • VRF-Lite
  • IP multicast
  • SSL VPN access

Value-added services: 

SRA (Secure Remote Access) 

IPSec VPN technology is independent of applications. It encrypt original IP information with its own packets, thus can hide all application protocol information. Through the establishment of IPSec encrypted tunnel, all kinds of connections can be achieved, such as Web, E-mail, file transfer and VoIP etc., and each transfer directly corresponds to relevant server behind the VPN gateway. As the biggest advantage of IPSec VPN, its customer supports all IP layer protocols and is completely transparent to application layer protocols.

  • Cost-effectively utilise customers’ existing Internet lines to build IPSec tunnels and is suitable for small branches;
  • Short installation period, thus can be used as an alternative for emergency opening;
  • Multiple access platform (Shenzhen/Beijing/Shanghai) support to achieve the best access effect

SRB (Secure Remote Backup)

  • Highly secure double-line backup mechanism: use different operator lines or different access nodes as backup;
  • IPSec VPN backup mechanism: use customers’ own Internet bandwidth and adopt IPSec VPN access, which is safe, reliable and inexpensive
