Information from network operators said that before the APG undersea cable route had problems on the S3 branch on July 26, another international undersea cable, AAG, was also faulty, causing service interruptions on the route.

Asia Pacific Gateway (APG) and Asia America Gateway (AAG) are 2 of 5 international undersea fiber optic cable routes that account for most of the Internet connection capacity from Vietnam to international destinations, along with 3 other routes including SMW3 (also known as SMW3 (also known as SMW3). SEA – ME – WE3), Pan Asia (IA – Intra Asia) and AAE-1 (Asia – Africa – Euro 1).

The fact that both AAG and APG have experienced problems in the past time has put a lot of pressure on Internet service providers (ISPs) in Vietnam to maintain the quality of international Internet services provided to users.

Specifically, information from a representative of an ISP said that in the middle of February and the end of June, respectively, the AAG cable route continuously encountered problems on connecting directions to Singapore and Hong Kong (China). In particular, with the Singapore cable direction, AAG had problems on branches S1B, S1D and power failure at TungKu landing station (Brunei). With the Hong Kong (China) connection direction, AAG has a “shunt fault” error on the S1H branch. The ISP representative also added that the problems on the AAG route have not yet had time to handle and fix.

Up to now, operators have not received notice of repair and troubleshooting plans on 2 cable lines AAG and APG (Artwork: Internet)

As for the APG cable, as reported by ICTnews, on the afternoon of July 26, this undersea cable system had a problem on segment S3, about 416km from Chongming (China) docking station. Because the source from Chongming station of the APG undersea cable is feeding the main shaft to S1.7, when a fault occurs on segment S3, there is no more power to S1.7. As a result, all traffic from Vietnam running through the main axis on the APG cable to Hong Kong (China), Singapore, Malaysia, and Japan is affected.

Immediately after the submarine cable problem, the network operators quickly planned to reroute capacity. At the same time, coordinate with the APG system to work with the contractor to study the source reconfiguration plan to restore traffic on the main axis as soon as possible.

As a result, on July 28, the system agreed with NEC’s proposal on the power reconfiguration plan. After the source was reconfigured, all connection traffic from Vietnam to Hong Kong (China) and Singapore via the main APG cable route was restored. Meanwhile, the connection traffic to Japan and Malaysia of this undersea cable route is still affected.

At present, network operators in Vietnam have not yet received notice of plans to repair and overcome problems on two submarine cable lines AAG and APG.

AAG is an undersea cable line that was put into operation more than 12 years ago, with a total length of 20,000 km and a design capacity of up to 2 Terabit/s, directly connecting Southeast Asia with the US. The cable route starts from Malaysia and ends in the US, the cable branch turns into Vietnam in section S1 with a length of 314 km.

Since being put into operation until now, AAG has encountered many problems. However, in fact, according to experts, AAG traffic is still used by many domestic carriers at a large rate. The reason is explained that, in economic terms, AAG is still the most affordable cable route. Therefore, in the usage structure of carriers, AAG is still an important element, especially for large carriers with many mobile Internet users.

Put into operation later, from mid-December 2016, APG has the participation of investment from Vietnamese carriers and is considered as an undersea cable route that contributes to bringing a stable transmission line with a larger capacity for customers. Internet users in Vietnam.

APG cable has a length of about 10,400 km, this cable is located under the Pacific Ocean, with the ability to provide a maximum bandwidth of up to 54 Tbps. This cable route has connection points in China, Hong Kong (China), Taiwan (China), Japan, Korea, Malaysia, Singapore, Thailand and Vietnam.
