Cisco Extends Enterprise WAN Solutions; High-End Router Enhancements will Improve Bandwidth Utilization, Security and Access.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--Oct. 29, 1996--Cisco Systems, Inc. today announced significant enhancements to its high-end routers that will enable network managers to improve bandwidth utilization, security and access in enterprise wide area networks (WANs), while reducing costs. These enhancements extend the company's comprehensive, Cisco IOS Cisco IOS (originally Internetwork Operating System) is the software used on the vast majority of Cisco Systems routers and all current Cisco network switches. IOS is a package of routing, switching, internetworking and telecommunications functions tightly integrated with a software-based solution set for enterprise WAN environments, which span from home and remote offices to headquarters data centers. "With the combination of enhanced Cisco IOS network services and new, higher density interfaces, we can offer cost-effective, integrated solutions across the entire enterprise WAN," said Richard Palmer, director of marketing for Cisco's high-end routing products. Improving Bandwidth Utilization As enterprises become more distributed, new mission-critical applications tax bandwidth availability. Network managers can solve these bandwidth constraints by adding new WAN links, but they are being pressured to reduce networking costs. Data compression technology maximizes bandwidth and increases WAN link efficiency by enabling more data to be sent in every packet. Consequently, network managers can cost-effectively increase application performance and service availability for end users without costly infrastructure upgrades. Cisco IOS compression services operate on both high-end, central site routers and on remote site routers to provide an integrated wide area networking solution. Cisco's new Compression Service Adapter (CSA (1) (Canadian Standards Association, Toronto, Ontario, www.csa.ca) A standards-defining organization founded in 1919. It is involved in many industries, including electronics, communications and information technology. ) enables central site routers to aggregate the compressed data streams from multiple remote site routers, which improves performance without impacting system resources. The CSA offloads Cisco IOS software compression algorithms from the main Route/Switch Processor (RSP RSP right sacroposterior (position of the fetus). ). The RSP remains dedicated to routing tasks, while the CSA optimizes compression performance. A single CSA can increase the compression capabilities of Cisco 7500 series routers from 10 to 20 times. And a Cisco 7513 router can support as many as 11 such adapters. Improving Security The rapidly growing use of the Internet and other WAN connections increases concern about securing corporate information assets from unauthorized access. To date, encryption services have been implemented on a limited basis. Either the additional network processing power required impacts router performance or the use of external link encryptors are too costly and difficult to manage. Cisco today announced the capability to distribute Cisco IOS encryption services to the Versatile Interface Processor Model 2-40 (VIP2-40). This enables large-scale deployment of encryption at central sites with high encryption requirements. The VIP2-40 offloads processor-intensive encryption tasks normally performed by the RSP to the processing capabilities of the VIP. Because the RSP is relieved of encryption tasks, it can dedicate its resources to ensuring high packet routing and switching performance. Network managers can use NetFlow Switching, a new Cisco IOS software switching mechanism, with Cisco IOS encryption services to selectively apply encryption to only the users, applications or sessions which require it. This improves overall network performance and is less expensive than encrypting all traffic on each link. Cisco IOS encryption features include Diffie-Hellman public key encryption See public key cryptography. (PKE PKE - public-key encryption ), Digital Signature Standard (DSS (1) (Digital Signature Standard) A National Security Administration standard for authenticating an electronic message. See RSA and digital signature. (2) (Digital Satellite S ) and Data Encryption Standard See DES. Data Encryption Standard - (DES) The NBS's popular, standard encryption algorithm. It is a product cipher that operates on 64-bit blocks of data, using a 56-bit key. It is defined in FIPS 46-1 (1988) (which supersedes FIPS 46 (1977)). (DES) algorithms. Both DSS and DES depend upon "crypto-maps" that use extended IP access lists to define network, subnet (SUBNETwork) A logical division of a local area network, which is created to improve performance and provide security. To enhance performance, subnets limit the number of nodes that compete for available bandwidth. , host or protocol pairs for encryption between routers. Improving Access to Enterprise WANs Today's enterprise WANs must be flexible and extendible to use an ever-changing mix of carrier services. New port adapter modules and interface processors for Cisco 7200, 7500 and 7000 series routers (with RSPs) will allow network managers to support more users and locations, over a wider variety of WAN access technologies, than ever before. These include: -- An eight-port serial port adapter module for high-density serial connections. With this port adapter, network administrators can provision eight T-1 (1.55 Mbps) or E-1 (2.048 Mbps) ports; four ports delivering speeds up to 4 Mbps, or two ports delivering speeds up to 8 Mbps (E-2). -- Channelized Refers to an architecture that transmits data in channels. It often refers to the 64 Kbps channels in T1 lines, which were originally developed to handle digitized voice streams (TDM). See TDM. T-3 interfaces for Cisco 7500 series routers that can aggregate traffic from 28 T-1 links and provide 45 Mbps of bandwidth on a single card. This solution delivers dedicated T-1 access at less than half the cost of any competing solution. -- A high-speed serial interface The High-Speed Serial Interface (HSSI) is a differential ECL serial interface standard developed by Cisco Systems and T3plus Networking primarily for use in WAN router connections. It is capable of speeds up to 52 Mbit/s with cables up to 50 feet in length. (HSSI (High-Speed Serial Interface) A serial interface with transmission rates up to 52 Mbps. It is often used to connect one or more LAN routers and network devices to a T3 line, which provides 44.736 Mbps. ) port adapter, which offers one to two full-duplex, 52 Mbps HSSI interfaces for use in distributed switching environments requiring large numbers of connections. -0-
