SK Telecom Deploys 10 Gbps Caspian Backbone for Flow-State QoS

South Korea's SK Telecom is deploying a 10 Gbps MPLS mesh backbone designed exclusively with Caspian's Media Controllers, core routers that perform both basic routing and Caspian's unique Flow-State QoS traffic management. Caspian also announced the availability of its Flow-State QoS technology on 10 Gbps Ethernet interfaces and (10) x 1-port GE interfaces. Caspian already offers OC192c/STM64 line cards and (4) x OC48c/STM16c cards.

Caspian said its Media Controllers' flow-state traffic management capabilities enable SK Telecom to deliver exceptional quality of service to its subscribers at broadband data rates without the cost and complexity involved in over-engineering the network. The Flow-State QoS technology identifies all unique IP traffic flows, without requiring invasive deep packet inspection. It then applies the fair use policies that dynamically deliver the QoS, bandwidth and priority required by each traffic flow. Caspian's custom-designed ASICs enable each 10-Gbps interface to process and retain state information for up to six million separate flows and thousands of policies simultaneously. Congestion is also mitigated proactively using Call Admission Control for VoIP and video traffic.

SK Telecom will use the network to provision e-Gov services, including high-quality VoIP, videoconferencing and other real-time multimedia applications, along with mission-critical virtual private networks and Internet access for government agencies and citizens alike.

Caspian said its Media Controllers deployed in the aggregation, backbone or peering points of existing IP or MPLS networks are able to provide deterministic QoS, zero-packet loss and a 2-3 times improvement in overall bandwidth utilization.

  • In June 2006, Caspian announced the second phase of its joint technology development partnership with Korea's Electronics and Telecommunications Research Institute (ETRI) to deliver new IPv6 services. Caspian and ETRI announced Phase I of their joint technology agreement in February 2005 to develop multimedia quality of service (QoS) solutions for South Korea's Broadband convergence Network (BcN) initiative. Phase II of the joint development agreement between Caspian and ETRI will focus on new IPv6 services that are part of a comprehensive IPv4-to-IPv6 migration strategy. Through its Phase I collaboration with ETRI, Caspian has successfully deployed its Media Controllers in South Korean's Electronic Government (e-Gov) network with Korea Telecom and SK Telecom. The e-Gov networks are one of many BcN initiatives that represent an ambitious countrywide network infrastructure to deliver dedicated bandwidth in support of integrated multimedia services including VoIP, streaming audio and video, and real-time health and welfare response services to 20 million Korean subscribers.

Use Networking: Leveraging Quality To Create Profitability
is “fair use�? of a service provider's network? Ideally, service
providers should be able to allocate capacity and be paid according to
what they carry over the network. While Internet access providers are
able to raise prices for customers who require more bandwidth, long-haul
backbone service providers pay the freight for growing volumes of
traffic from which they generate no revenue, and worse, rob capacity at
the expense of premium services

Today there seem to be two approaches to the problem of balancing
network traffic and revenue considerations. The first approach is to
simply let any customer transport any kind of traffic—and as much as
they want—over the long-haul backbone network. The second approach
available to service providers for managing bandwidth is to filter out
certain types of traffic or lock out traffic from certain content
