Further news about the integration of IP and ATM for VoIP and other applications, this time from CSCO. ===== CISCO LAUNCHES IP+ATM SOLUTION FOR SERVICE PROVIDER INFRASTRUCTURES June 19, 1998 EUROPEAN BROADBAND NETWORKING NEWS via NewsEdge Corporation -- Cisco has launched new products for carrier-class, IP-based services through the integration of IP and ATM technologies. Benefits The platforms are designed to integrate ATM and advanced IP capabilities immediately and also to enable high growth services of the future. Cisco's IP+ATM brings IOS software to carrier-class ATM networks, to facilitate IP QoS, scalability, security, and management tools, without adding proprietary protocols internal to the IP+ATM network. Service providers will be able to provide seamless interoperability with enterprise customers' networks that are currently running Cisco IOS software. Tag switching Cisco integrates its IP and ATM technologies through the implementation of the emerging Multiprotocol Label Switching (MPLS) standard. Cisco offered Tag Switching to the Internet Engineering Task Force (IETF) as the basis for the emerging MPLS standard. Tag Switching integrates IP and ATM technologies, so that service providers have the privacy characteristics and quality of service (QoS) benefits of ATM along with the universal connectivity of IP. Tag Switching integrates IP and ATM within the same networking environment, such that service providers can maximise their return on investment by leveraging multiple revenue streams from a single platform. Service providers also can deploy next-generation, IP-based services by introducing MPLS-capable switches to their existing ATM infrastructures. Cost savings Integrated edge and core products offer savings in network infrastructure costs because they enable service providers to combine separate networking capabilities onto one network. The products * BPX 8650 IP+ATM switch (now shipping) * MGX 8800 wide-area edge switch * BPX 8680 universal service node * TGX 8750 optical core switch The switches use Cisco IOS software for end-to-end network interoperability within carrier-class ATM networks. With the introduction of these platforms, Cisco is providing the industry's widest range of building blocks for service providers to construct integrated IP+ATM network infrastructures. Cisco's IP+ATM integrated edge products - the BPX 8650 IP+ATM switch, the MGX 8800 wide-area edge switch and the BPX 8680 universal service node - meet service providers' customers at the edge of the WAN, where they link seamlessly to enterprise networking environments. BPX 8650 IP+ATM switch : This incorporates MPLS for dynamic IP switching over the ATM fabric. Using Cisco's upgrade package, service providers can upgrade their existing installed base of BPX 8600 series switches to incorporate MPLS for IP+ATM capabilities. MGX 8800 wide-area edge switch: This meets the needs of small to large points of presence (PoPs) or central offices (COs), where service providers need to scale to 1,400 DS1 interfaces. For very large sites that need to handle up to 16,000 DS1 interfaces, Cisco designed the BPX 8680 universal service node. The Cisco MGX 8800 wide-area edge switch represents the next generation in high-capacity edge switches. Featuring the industry's widest breadth of service interfaces, the MGX 8800 wide-area edge switch enables service providers to deliver a complete portfolio of differentiated service offerings while scaling from DS0 to OC-48c/STM- 16 speeds. The MGX 8800 platform provides the lowest-cost edge infrastructure for volume services such as frame relay by reducing the entry cost and surpassing the port densities of competitive switches. US WEST !NTERPRISE plans to test the MGX 8800 wide-area switch later this summer and is interested because of the high speed architecture and variety of interfaces supported. TGX 8750 optical core switch: To meet the needs of today's WAN core, service providers require a standards-based IP+ATM solution that provides resilient edge-to-edge connectivity for integrated IP+ATM network edges. With the emergence of Dense Wave Division Multiplexing (DWDM) technologies, service providers also require the next generation of core switches to have the flexibility for connecting to an all-optical core using an OC-48c interface. The Cisco TGX 8750 optical core switch meets these requirements, with integrated MPLS/Tag Switching capabilities and both OC-48 and OC- 48c interfaces. The Cisco TGX 8750 optical core switch is the first product in its class to offer hierarchical Private Network-Network Interface (PNNI), which enables massive scalability for ATM networks. Service management Cisco's service management tools provide management capabilities for the planning, provisioning, operating and billing of IP+ATM revenue-generating services. This could mean a cost-effective migration path for service providers who operate a multivendor network and want to integrate the new switches while protecting investments in existing systems. Integrating IP and ATM With an integrated IP+ATM infrastructure, service providers can still deliver high-revenue services (Frame Relay, SNA, leased-line and Internet dial access while futureproofing service providers' networks by enabling advanced IP services. These services include: * virtual private networks (VPNs) * managed intranet and extranet solutions * voice over IP (VoIP) * intranet content hosting * electronic commerce applications
