System Architecture Services

The PurePacket™ System which includes the PurePacketNode, PurePacketOUTburst ® IADs and PurePacketOMS™ (Operations Management System), provides Carrier Class support for legacy and emerging services. Converged voice and data on a single access line provides Internet access, VoIP/VoMPLS, voice/POTS LAN extension (leased line) and IP VPN (Virtual Private Networks).

Dynamic bandwidth allocation provides considerable cost savings for carriers and customers alike, by ensuring that access bandwidth is fully utilized at all times. Committed and Peak Information Rate (CIR/PIR) thresholds can be provisioned for supporting differentiated classes of service as well as billing services within the PurePacketOMS™.

A broad range of Interworking Functions leverage existing technologies including Frame Relay, SONET and GR-303/V5.2 based voice switches, while seamlessly integrating with IP/MPLS optical transport. Voice services can be built on Class 5 or SoftSwitch architectures. PurePacket is unique in supporting both SoftSwitch and Class 5 interworking simultaneously. In this way a service provider can leverage the existing investment in Class 5 switches while expanding services on a SoftSwitch based system.

Compatibility and Integration

The PurePacket System has all the required interfaces and communications protocols to connect existing and emerging infrastructure. These include analog and digital voice, ISDN, serial and Ethernet data ports as well as PPP and Frame Relay.

Redundancy

The PurePacket NEBS-3 compliant platform provides common element 1+1 protection, as well as 1:N trunk and access protection. Redundant LSPs can be provisioned for automated fail over protection ensuring a truly "hitless" system delivering "five nines" reliability. Interface cards comprised of Communication Function Modules (CFMs) that contain the active components, and InterFace Adapter Modules (IFAMs) that contain the physical interface and passive components, further ensure Carrier Class operation.

PurePacketNode Architecture
All services are packetized at the ingress to PurePacket and mapped to Label Switched Paths (LSPs) which provide intelligent virtual connections. Each LSP is individually managed and engineered to meet QoS/CoS requirements for each service type. Policy enforcing SLAs ensure customer requirements are met, and enable Service Providers to create a virtually unlimited portfolio of differentiated IP-based services. By classifying traffic and establishing LSPs at the customer premises, the PurePacket solution is able to ensure end-to-end QoS without the overhead or complexity of overlay networks.

Advanced Traffic Management and Class of Service (CoS)
To ensure that critical service levels are met, PurePacket employs MPLS-like traffic engineering and intelligent traffic management (queuing, buffering, marking, etc.). Traffic, depending upon mission criticality and time sensitivity, is classified at the customer premise and mapped to a Class of Service (CoS) / Quality of Service (QoS), which correlates to a class-specific, customer-specific LSP. PurePacket enables the creation and delivery of multiple service classes—including Real-Time, Committed Information Rate (CIR), and Best Effort (BE)—each with an unlimited range of traffic contract options.

Bandwidth Management
Label Switching and VoMPLS provide high performance, secure forwarding of traffic with minimal added overhead, ensuring maximum throughput of user voice and data. Silence suppression and dynamic bandwidth allocation,
Call Admission Control and differentiated services levels allow bandwidth optimization to deliver more services over the bandwidth contrained local loop.

SoftSwitch Call Control
SoftSwitch architectures enable carriers to incrementally build-out voice-switching solutions while leveraging the scalability, efficiencies, and openness inherent to IP client-server architectures. This results in significant time-to-market advantages and fulfills the promise of converged communications. PurePacket serves as a Media Access Gateway in this architecture and operates under SoftSwitch call control to establish and terminate packet-based voice and emerging, multi-media communication services. In combination with a SoftSwitch, PurePacket can augment or replace a Class 5 voice switch for a fraction of the cost. Our commitment to open standards such as MGCP (Media Gateway Control Protocol), SIP (Session Initiated Protocol) and H.248 ensure a clear migration path.

Label Switching
Label Switching delivers deterministic behavior to connectionless, IP-based networks enabling end-to-end QoS/CoS without the cost of an overlay network. As a link independent protocol, Label Switching also provides a common control plane and smooth hand-off to ATM backbones where necessary. Designed to address scaling issues with the routed IP Internet core, Label Switching delivers the speed and efficiencies of a layer 2 network while leveraging the intelligence and scalability of layer 3 networks. By implementing Label Switching and advanced traffic management PurePacket extends the value of IP from the customer premises to the core.
