What is BGP Peering?
- BGP peering is an Internet protocol used among network operators that manage how packets are routed across the Internet through the exchange of routing and reachability information between edge routers. It provides the best routing decisions for networks interconnected in the BGP peering mode. BGP peering neighbors, called peers, are established by manual configuration between routers to create a TCP session on port 179. A BGP speaker sends 19-byte keep-alive messages every 60 seconds to maintain the connection.
- An Internet service provider must obtain an AS (Autonomous System) number from regulatory authorities to be able to take advantage of direct BGP peering.
- CDS has been operating BGP networks since 1998 and currently holds two numbers: APNIC AS38353 and ARIN AS 63199.
CDS offers two options for BGP Peering – Global BGP and 4-Line BGP
Global BGP is recommended for:
Any office in China that needs fast, reliable Internet access from China to the world. Global BGP peering is designed for use by international enterprises using CDS’ Beijing Data Center as their IT hub to provide Internet access from China to anywhere in the world with significantly lower latency and higher availability. A CDS Global BGP peer enabled server can provide reliable access to services such as Google, Facebook, and Wikipedia*.
When Global BGP is assigned to a Virtual Data Center, the host’s IP address is “broadcast” to all AS networks worldwide with direct peering to CDS. All routing requests to the host’s IP addresses are then directly routed to CDS’ network without any searching, forwarding, and transmitting – significantly lowering latency.

*Use of Global BGP feature is subject to regulatory approval
4-Line BGP is recommended for:
Businesses with a presence in China for whom mobile users, or users in educational settings are critical.
CDS’ 4 Line BGP peering provides carrier-neutral services to mobile users and Education Net users, who suffer significant delays due to congestion at the internetworking gateway. Currently, there are four major carriers: China Telecom, China Unicom, China Mobile and CERNET. All four ISPs provide nationwide coverage which overlaps, but because they target different markets and a history of division, each ISP has its own segment of customers. For example, China Telecom has the largest user base in southern China, China Unicom dominates local access in northern China, and the educational institutions are almost exclusively serviced by the Education Net, CERNET.
Unlike the majority of the world, these four networks are connected to each other by only ten access points. Seven of which were added in 2015.
Without multi-line BGP, provided by a third party like CDS, even local Internet traffic between ISPs would have to go through an access point which might be thousands of miles away.
