SAN JOSE, Calif.--(BUSINESS WIRE)--March 4, 2002
Cisco Systems, Inc. (Nasdaq:CSCO CSCO Cisco Systems Incorporated (stock symbol)
CSCO Chief Supply Chain Officer ), the worldwide leader in networking for the Internet announces its Unified VPN (Virtual Private Network) A private network that is configured within a public network (a carrier's network or the Internet) in order to take advantage of the economies of scale and management facilities of large networks. Suite, the industry's most complete set of Layer 2 and Layer 3 VPN technologies, integrated across Cisco's core and access platform portfolio, supporting the largest common set of IP services, and provisioning capabilities. Cisco's Unified VPN Suite delivers new VPN technology for IP and MPLS (1) (MultiProtocol Lambda Switching) The earlier name for GMPLS. See GMPLS.
(2) (MultiProtocol Label Switching) A standard from the IETF for including routing information in the packets of an IP network. backbone networks, increasing service providers' reach and revenues and enterprises' choices and flexibility. This comprehensive delivery includes new protocols such as Any Transport over MPLS (AToM) and Layer 2 Tunneling Protocol See L2TP. version 3 (L2TPv3), new deployment capabilities via Cisco Easy VPN and enhancements for integrating IPSec with MPLS. Complementing this are new VPN provisioning tools for both service provider and enterprises environments.
"Cisco's Unified VPN suite enables service providers to support both Layer 2 and Layer 3 VPN services across their IP or MPLS core," said Dave Passmore, Research Director, The Burton Group. "This will enable them to leverage their investment in an IP-based multi-service infrastructure."
"With Sprint's IP over DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM.
DWDM - wavelength division multiplexing backbone, L2TPv3 appears to offer a promising path to efficiently deliver Layer 2 services," said Barry Tishgart, Director -- Data Product Management. "Sprint is evaluating L2TPv3 technology and service attributes, and the demand for the services L2TPv3 enables."
Through support for a common suite of Cisco IOS(R) Software services, Cisco Unified VPN Suite allows service providers to offer customers a consistent set of advanced network services across their VPN networks including security, Quality-of-Service (QoS), NetFlow, SLAs via Cisco's Service Assurance Agent, and MPLS-based traffic engineering.
"Service providers want to take advantage of their IP or MPLS backbones while expanding their Layer 2 access revenues," said Sangeeta Anand, senior director of Product Marketing for Cisco's Internet Technologies Division. "Cisco's Unified VPN Suite enables them to expand their reach, introduce new IP service offerings, and cost effectively transport existing access traffic over their packet backbones."
Unified VPN Suite -- Protocols
Any Transport over MPLS (AToM)
Cisco's Any Transport over MPLS (AToM) solution allows transport of Layer 2 services across a MPLS core network. Cisco's AToM, based on the IETF See Internet Engineering Task Force.
IETF - Internet Engineering Task Force `martini draft' (draft-martini-l2circuit-trans-mpls-08.txt)), allows the service provider to take full advantage of the inherent benefits of an MPLS backbone such as traffic engineering and bandwidth guarantees. Cisco's AToM delivery includes support for Layer 2 technology for Ethernet over MPLS (EoMPLS), ATM AAL (ATM Adaption Layer) The part of the ATM protocol that breaks up application packets into 48-byte payloads which become ATM cells when the 5-byte headers are attached. The AAL resides between the higher layer transport protocols and the ATM layer. 5, ATM Cell Relay, Frame Relay, PPP (Point-to-Point Protocol) The most popular method for transporting IP packets over a serial link between the user and the ISP. Developed in 1994 by the IETF and superseding the SLIP protocol, PPP establishes the session between the user's computer and the ISP using , and HDLC (High-level Data Link Control) A data link protocol from ISO for point-to-point communications over serial links. Derived from IBM's SDLC protocol, HDLC has been the basis for numerous protocols including X.25, ISDN, T1, SS7, GSM, CDPD, PPP and others. over MPLS. Packet over SONET A metropolitan area network (MAN) or wide area network (WAN) transport technology that carries IP packets directly over SONET transmission without any data link facility such as ATM in between. (PoS) will be available later.
Layer 2Tunneling Protocol, version 3 (L2TPv3)
To transport Layer 2 access over native IP backbones, Cisco has pioneered the new L2TPv3 protocol. It is based on optimized extensions to the underlying L2TP (Layer 2 Tunneling Protocol) A protocol from the IETF that allows a PPP session to travel over multiple links and networks. L2TP is used to allow remote users access to the corporate network. standard and includes signaling enhancements, a new encapsulation header, and a protocol identifier to support the end-to-end transportation of multiple Layer 2 protocols. Currently, an IETF draft (draft-ietf-l2tpext-l2tp-base-01), it incorporates support for Frame Relay, ATM, HDLC, PPP, and Ethernet. L2TPv3 can also provision transit tunnels across multiple MPLS and IP packet core networks.
IPSec VPNs continue expansion in the enterprises for remote and peer-to-peer access. With this delivery, Cisco is adding IPSec to MPLS integration, which enables enterprise-sourced IPSec VPNs to be combined with an MPLS backbone.
Unified VPN Suite -- Provisioning
Cisco's VPN Solution Center (VPNSC) makes use of both Cisco products and third party solutions, such as WANDL WANDL Wide Area Network Design Laboratory , Concord NHM NHM Natural History Museum
NHM Naturhistorisches Museum (Natural History Museum, Vienna, Austria)
NHM Neurally Mediated Hypotension
NHM New Horizon Media (Chennai, India publisher) , and Visual Networks to provide service activation, monitoring, reporting, intrusion detection and policy management, for Frame Relay, ATM, PoS, PPP, HDLC, IPSec, and Ethernet VPNs. For Enterprises, the VPN Management System (VMS (1) (Virtual Memory System) A multiuser, multitasking, virtual memory operating system for the VAX series from Digital. VMS applications run on any VAX from the MicroVAX to the largest unit. See OpenVMS. ) will create Monitoring and Reporting, Intrusion Detection and Policy Management, for IPSec, but also for other Cisco IOS VPN technologies.
Cisco Easy VPN, a software enhancement based on Cisco's Unified Client Framework, provides a consistent connection and policy and key management method across Cisco's routers, security appliances and VPN clients. This feature allows users to deploy any Cisco Easy VPN-enabled device within a common VPN framework. For remote connections, Cisco Easy VPN enables Cisco routers and security appliances to automatically establish and maintain a VPN tunnel to a Cisco Easy VPN-enabled head-end device without complex remote configuration. For head-end applications, Cisco Easy VPN accepts incoming calls from remote Cisco Easy VPN-enabled devices and verifies that those connections have up-to-date policies in place before the connection is established. In addition, Cisco IOS-based head-ends can now terminate VPN connections from Cisco VPN software clients.
Unified VPN Suite -- Platform Availability
Cisco's Unified VPN Suite is available in Cisco IOS Software releases 12.0S and 12.2T for the appropriate platforms ranging from the Cisco 800 access routers to the Cisco 12000 Internet routers.
