In-depth Analysis Report On The Coverage Area And Interconnection Quality Of The Three Networks In Malaysia (CN2)

Question 1: Three Networks CN2 In Coverage area in Malaysia So, how exactly does it work?

In summary, Three Networks CN2 Through China Telecom’s CN2 backbone network, connections are established with overseas partners and submarine cable nodes, allowing traffic to be routed to major Malaysian cities such as Kuala Lumpur and Penang, as well as to large data centers. The actual coverage depends on the supplier’s local POP deployment and interconnection partners. Currently, most international operators have direct or near-end access points in Kuala Lumpur, which results in relatively good coverage in urban areas. However, in rural and remote areas, coverage still relies on local last-mile connectivity solutions.

Technical Key Points

The route from CN2 to Malaysia typically utilizes multiple submarine fiber optic cables and edge switching nodes, enabling optimal routing for international exports. The key factor in this regard is whether the supplier provides local POPs and whether it has established peering connections with major Malaysian IXPs or large telecom operators.

Factors affecting coverage

This includes the number of locations where submarine cables are landed, local data center partnerships, interconnection strategies (direct connections or relays), and whether commercial solutions such as MPLS/SD-WAN are supported.

Tip

When selecting a service, it is important to inquire about the specific POP locations and the list of peer partners. Actual measured latency and routing paths are more reliable than what is promised in written materials.

Question 2: Malaysian region Quality of Interconnection among the Three Networks How does it usually perform?

Overall, the quality of Malaysia's external connectivity is significantly influenced by the health of undersea cables, regional routing strategies, and the attitudes of local operators towards interconnection. Paths that use direct connections over CN2 generally offer better stability, lower latency, and lower packet loss rates compared to traditional public network routes. However, their performance can still be affected by nighttime congestion, submarine cable maintenance activities, or link failures.

Common quality indicators

Key metrics include Round-Trip Time (RTT), packet loss rate, jitter, and routing stability. CN2 It can generally be done Delay Reducing the latency by 10-30 milliseconds and lowering the packet loss rate to even lower levels does not necessarily result in a consistent advantage across all nodes.

Observation channels

It is recommended to collect data at different times using multiple monitoring tools (Ping/Traceroute/MTR/RIPE/Looking Glass) to observe any differences in performance during peak periods compared to cable maintenance windows.

Attention

Don’t just look at the speed test results once; long-term stability is what truly matters when evaluating the quality of an internet connection.

Question 3: What are the differences between CN2 and regular multi-line connections in terms of latency and packet loss?

CN2 The value lies in high-quality routing strategies and a controlled backbone network, which typically result in fewer hops and less unpredictable routing delays. This directly translates into lower latency and more stable packet loss performance. Regular multi-line connections (international links that have not been specifically optimized) may go through more routing points and are therefore more prone to fluctuations in performance when encountering congestion or changes in routing policies.

Numerical reference (typical range)

From China to Malaysia: The round-trip latency for CN2 routes is generally within… 40–70 milliseconds Ranges; traditional routes may fall within these ranges 60–120 milliseconds … In terms of packet loss, CN2 is able to maintain levels close to zero during normal operating hours <0.1%级别，普通链路峰值丢包可能上升到0.5%甚至更高。

Why are there differences?

The differences stem from the choice of submarine cables, the strategies employed between ASs, whether there is a direct connection to the target network, and the level of investment suppliers make in QoS and traffic engineering.

How to verify it?

Use long-term MTR records, multi-time period measurements, and BGP route analysis to confirm the actual differences.

Question 4: What are the actual impacts of CN2 on enterprises and applications such as gaming and video?

For enterprise applications such as VPNs, financial transactions, and cross-border operations, CN2 It offers lower latency and better SLA guarantees, reducing transaction/synchronization delays as well as the risk of packet loss. For real-time interactive applications such as online games and real-time voice/video communications, low latency and stable pathways can significantly enhance the user experience by reducing lag caused by packet loss, as well as the need for retransmissions.

The different focuses of various applications

Enterprises place greater emphasis on measurable SLAs and controllable routing ； In games and live broadcasts, latency jitter and performance during peak hours are of greater importance. Combining CDN/edge caching with CN2 can achieve better playback stability.

Recommendations for commercial deployment

By combining a multi-line strategy (CN2 + local CDN + backup links) with the deployment of SD-WAN for path selection and failover, it is possible to achieve a balance between cost and performance.

User-side operations

It is recommended to conduct a gray-box testing before launching the product, and request that the supplier provide a trial period or performance documentation to assess the actual experience.

Question 5: How to evaluate and select a suitable CN2 service provider for multiple networks?

The evaluation should take into account four aspects: coverage and connectivity, technical capabilities, SLA and monitoring capabilities, as well as pricing and support. First, verify whether there is a local POP available, whether a direct connection or peering relationship has been established with a major Malaysian operator, and check the historical records of any outages or maintenance announcements.

Key Verification Checklist

① POP and Peer List ； ② Diversity of submarine cables and backup pathways ； ③ SLA terms (packet loss/delay/recovery time) ； ④ Visual monitoring and reporting interface ； ⑤ Frequency of customer service responses and fault simulation exercises.

Testing methods

Require suppliers to provide test accounts or conduct live traffic trials. Use tools such as Ping/MTR, two-way speed testing, and service simulations (for games/video) to compare data during peak and off-peak hours.

Purchasing recommendations

Give priority to suppliers that offer localization support, provide trial versions of their services, and make their routing strategies publicly available ； When signing the contract, include the key performance indicators in the agreement and establish a mechanism for regular retesting and optimization.
