SK Telink extends Acme Packet deployment for debut of IP international calling

Net-Net session border controllers secure IP borders and ease interoperability for South Korean service provider migrating from TDM to IP

BEDFORD, MA, APRIL 5, 2011 — Acme Packet® (NASDAQ: APKT), the leader in session delivery networks, today announced that South Korean competitive service provider SK Telink has deployed Acme Packet’s Net-Net 4500 session border controllers (SBCs) for use in their SK 00700 international calling and SK Speed 070 IP telephony services. The Net-Net 4500s are located at SK Telink’s access and interconnect borders and supplement existing Acme Packet SBCs that support SK Telink’s IP Centrex service.

SK Telink, a subsidiary of SK Telecom, is one of the leading operators in South Korea offering international calling services. They also offer retail VoIP services to South Korean companies and outsourced data center services for smaller IP telephony service providers. SK Telink currently services hundreds of thousands subscribers who generate hundreds of thousands calls per day from corporate VoIP endpoints.

With the Net-Net 4500 deployment, SK Telink is replacing its TDM-based interconnects with an end-to-end IP architecture, which it intends to leverage into additional and more diverse peering relationships. SK Telink’s initial IP peering arrangement is with a major global service provider. SK Telink selected Acme Packet for its powerful Net-SAFE security framework, as well as the ability for the Net-Net 4500 solution to address complex SIP interoperability challenges.

“In evaluating alternative solutions, Acme Packet delivered the most comprehensive features and superior performance,” said Joong Seon Ji, team leader of SK Telink’s network planning team. “With the Net-Net 4500, we can peer with up to 100 international service providers, which will help us expand revenues beyond what is possible with the current approach.”

Acme Packet’s SBCs deliver rich functionality that SK Telink applies to extend service reach and secure its network and service infrastructure. SIP and SDP header manipulation applied at IP interconnect points normalizes signaling interactions between SK Telink and other service providers. The Acme Packet SBCs hide SK Telink’s internal topology from outsiders and prevent bad or malformed packets from infiltrating the service core. They also protect SK Telink’s access network and services by rate-limiting SIP signaling traffic and performing overload protection and protocol conformance verification to prevent service outages from DoS/DDoS attacks. Dynamic and static access controls are also configured to prevent fraudulent use or theft of SK Telink services.

“Our session border controllers open the door for service providers to offer new services and ways of extending services via IP peering relationships,” said Dino Di Palma, Acme Packet’s senior vice president of sales and business development. “SK Telink is leveraging the benefits of switching to IP as its transport for global communications.”
