Peering Challenges (1)
(cid:2)
Intra-Asia traffic can route out of region when
peering with Asia region ASes of global partners
– Big Asian ISPs tend to interconnect on the
US west coast, not Asia, with transit providers
(i.e. regional AS for US)
– Additional AS hop increases latency
(cid:2)
Careful traffic engineering when peering in
multiple world regions with global partners under
single ASes
– Exchange significant US/Europe-bound traffic
(from Asia) in the US/Europe, not in Asia
(cid:2)
Domestic/regional provider refuse to peer to
maintain hold on local content and customers

Peering Challenges (2)
(cid:2)
Peering partner POP not in countries where T-
Systems is present
– Expensive IPL to connect to partner location
(cid:2)
Minimize high network infrastructure costs
– Peer at major Internet exchanges
– Optimize with few and/or cheaper port
interface types
– Sea cable paths to high value content
– Avoid domestic peering via local loop
