With the high integrated global economy and digitalized commercial development, high upload and download speeds over a reliable and secured connection are now a basic prerequisite in organizations of any size. By using dedicated Internet connectivity services, we provide high-speed and reliable internet access designed exclusively for the corporation to cater to their internet communication needs and respond quickly to ever-changing markets.
GOIP AULA LTD’s connectivity service offers a premium class of local and international access service with high-speed connection needed for critical business functions.
GOIP AULA LTD provides high-speed internet access with a committed rate and flexible internet access connected with multiple Tier-1 providers in Hong Kong and China to suit for your business needs.
Ethernet has become the reigning standard in Local Area Networks (LAN). Our Ethernet WAN offers un-contended Internet bandwidth that no other business will share.
Systems and platform such as Enterprise Resource Planning (ERP), Supply-Chain Management (SCM) and Customer Relationship Management (CRM) are driving the need to connect various offices across China and Worldwide. Enterprises require high quality, high performance bandwidth solutions from a trusted and reliable ICT service provider.

Are MPLS-VPNs secure?
Since MPLS-VPNs do not require encryption, there is often a concern over the security implications of using MPLS to tunnel non-encrypted traffic over a public IP network.
There are a couple of points to consider in this debate:
- MPLS-VPN traffic is isolated by the use of tags, much in the same way ATM and Frame Relay PVCs are kept isolated in a public ATM/Frame Relay network.
- MPLS-VPNs do not prohibit security. If security is an issue, traffic can be encrypted before it is encapsulated into MPLS by using a protocol such as IPSec or SSL.
Customers comfortable with carrying their traffic over public ATM or Frame Relay services should have the same level of comfort with MPLS-VPN services.

SD - Wan
SD-WAN is good for these scenarios
- Mission critical data real-time transferring
- Real-time video/audio contents delivery
- DC to SaaS, SaaS to SaaS, Office to SaaS
- Accelerates international branches connections
- Accelerates international SaaS connections
- Accelerates international real-time content delivery
- Security, Stable, and Fast international WAN solution
Managed SD-WAN allows WAN traffic to be securely distributed over most carrier service offerings, including IP Virtual Private Networks (VPNs) or IEPL. With transport independence you can route your traffic through the most efficient channel while maintaining optimal performance of your applications.
Intelligent Path Control
Ensure critical applications are sent via the best possible path with Managed SD-WAN dynamically forwarding data packets based on the application type, performance, policies and path status. Managed SD-WAN monitors network performance for jitter, packet loss and delay, and load balances traffic to maximize available WAN bandwidth.
SD-WAN technology enables the hybrid WAN to react to changing network conditions automatically. That, by itself, means the WAN is flexible in a way that it likely wasn’t before. But in addition to that flexibility, an organization gains back time for its IT staff, as well as budget in the form of reduced capex for new circuits and opex for the WAN infrastructure.
With a software-defined WAN, an enterprise should be able to rely more on broadband and less on private links. Broadband won’t provide quality guarantees, so the SD-WAN will take active measurements between endpoints to know whether the broadband link is capable of carrying, say, voice or video traffic reliably. As Skype users know, it’s entirely possible to run voice and video over the public Internet.
That said, SD-WAN can handle those occasions where broadband quality is inferior and shunt traffic over the private link with guaranteed quality only as needed. As a result, organizations should be able invest in larger, cheaper broadband links and minimize the size of their expensive private links.
Configuring a hybrid WAN by hand is a challenge. Routing protocols, unless influenced by an outside source, choose a single best path to get between two sites and stick with it. Routing protocols don’t react to changing network circumstances such as packet loss, excessive jitter, or congested links; routing protocol metrics simply don’t include that sort of information in their best path calculations. Measurement techniques like IP SLA or PfR can artificially change metrics or otherwise override the normal behavior of a routing protocol, but these are tricky tools to configure.
SD-WAN handles this work for an organization in an automated way, routing and rerouting traffic dynamically based on the current state of the network. The IT team tells the SD-WAN application how certain traffic should be treated, and the solution takes care of the rest. To be more precise, the complexity doesn’t actually go away — it’s simply hidden by the SD-WAN application doing all of the heavy lifting.
Software-defined WAN caveats
Perhaps the greatest challenge when evaluating SD-WAN technologies is the ROI calculation. The capex and opex of the SD-WAN solution will need to be compared to the overall cost of the WAN itself. The idea is that a hybrid WAN that makes heavier use of cheap broadband should allow for smaller private links; some offices might not require private links at all.
As a result, this ROI calculation could reveal that an SD-WAN purchase will pay for itself or even save money. The catch in downsizing or eliminating private circuits is that most carriers lock their enterprise customers in with a multi-year contract. Thus, penalties for early termination or service-level changes could further impact ROI.
Another consideration when evaluating SD-WAN technology is that of vendor lock-in. There are several SD-WAN products, and they are all different and incompatible. Some layer on to a WAN; some replace WAN hardware with their own. An evaluation process should carefully consider the long-term commitment to the vendor.
Closely tied to this is the notion that an SD-WAN solution must be integrated into an organization’s WAN. If the product requires hardware replacement, has that hardware already been depreciated? This could be a hidden cost that needs to be considered, beyond the practical operational costs of implementing a new IT solution.
