IP S e rv ic e s

The migrat ion to IP a s the mechanism for

interconnecting computers, netwo rks, and

solutions requires a strong fo undation t hat

delivers a breadth o f feat ures and provides the

flexibil ity to enable the foundation to be adapted

to todays network requirements and evolvea s thenetwo rk grow s to meet future demands.

Cisco IO S softwa re contains a w ide array of

critical netw ork services designed fo r flexibility,

scalability, and reliability to help solve the most

difficult problems facing enterprises and service

providers. Customers can select the appropriate

Cisco IO S softw are feature sets to meet their

evolving network requirements. Features such as

Netw ork Address Translation (NAT), Dynamic

Host Configuration Protocol (DHCP), and Hot

Standby R outer Protocol (HSRP) can be easily

deployed individually or in combination w ith

each other across a widerangeof Cisco platforms

(from the low-end Cisco 800 series to a Cisco

7500 or Layer 3 switch).

Cisco IP Services comprises many basic and

adva nced building blocks that enable customers

to :

Deploy a n IP network w ith basic end-to-end IP

connectivity

Manage their IP addressing requirementsfrom a

central locat ion

Co ntrol the IP addressing scheme usedthroughout their network

Provide redundancy at major netw ork

connection points

Cisco IO S Sof tware IP Serv ices :

DHCP for Greater Network Serviceability

D H CP is a set of Internet stand ards (RFC 2131, 2132,

1534) that enable workstat ions and devices to request an

IP address for connection to an IP network. DH CP defines

three components: client, relay agent, and server. Cisco

IOS soft w are implements all three components, and

customers use these components to simplify and manage

thedeployment of their network to both new and exist ing

locations.

NAT for Increased Scalability

NAT is an Internet standard (RFC 1631) for translatingor changing IP a ddressing information a s it passes

through an IP network. Cisco has an implementation of a

super-set of the standard, and provides customers the

ability to dynamically translate or stat ically change an IP

add ress, as w ell as multiplex ma ny users to one or a few

IP addresses.

NAT DHCP HSRP

Enables a privately addressed network

to access registered networks, such as

the Internet, without requiring registered

IP addresses on end hosts

Enables connectivity between networks

with overlapping (duplicate) private

addresses

Eliminates theneedforhostrenumbering

Enables many-to-one IP address mapping

Automates client and device IP address

requirement for manual configuration

Enables centralized network

Eliminates single point of failure at the

first hop

Provides transparent fail-over without

requiring hosts to run special routing

software

Increases network availability

HSRP for High Availability

Mission-critical applications are vital to business.

Network downtime can cost mill ions of dollars per hour

in lost revenue. A reliable netw ork starts w ith a good

design that includes redundant systems and links. Cisco

IOS software reliability services include HSRP, which

provides network redundancy for IP networks in a way

tha t ensures that user traffi c w ill immediately and

transparently recover from fi rst-hop fa ilures in netw ork

edge deviceso r access circuits. HSRP is particularly useful

when users on one subnet require continuous access to

resources in the network.Cisco End-to-End Solutions

C isco internetwo rking devices interconnect more media

types than any other networking vendor. C isco IOS

softw are provides an end-to-end founda tion tha t

centralizes mana gement a nd confi guration, enab les

fault-tolerant reliability, a nd a llows netw orks to scale to

meet the demands of netwo rk grow th and emerging

services and solutions.
