This module introduces students to Extensible Markup Language (XML) Web
services and how students can use them to process purchase orders from
business-to-business (B2B) trading partners. Students will learn how to choose
XML Web services and how to integrate them in their order processing
workflow. Students will also explore the requirements for hosting their own
XML Web services and providing them to trading partners.

This publication provides internetworking design and implementation information and helps you
identify and implement practical internetworking strategies that are both flexible and scalable.
This publication was developed to assist professionals preparing for Cisco Certified Internetwork
Expert (CCIE) candidacy, though it is a valuable resource for all internetworking professionals. It is
designed for use in conjunction with other Cisco manuals or as a standalone reference. You may find
it helpful to refer to the Cisco CCIE Fundamentals: Case Studies, which provides case studies and
examples of the network design strategies described in this book....

T
he new Cisco certifications reach beyond the popular certifications,
such as the MCSE and CNE, to provide you with an indispensable factor in
understanding today’s network—insight into the Cisco world of internetworking.
This book is intended to help you continue on your exciting new
path toward obtaining CCNP and CCIE certification. Before reading this
book, you should have at least read the
CCNA: Cisco Certified Network
Associate Study Guide
(Sybex, 2000). While you can take the CCNP tests in
any order, you should pass the CCNA exam before pursuing your CCNP.
Many questions in the 640-505 exam are built upon the CCNA material.
However, we have done everything possible to make...

Routing is an essential element of all but the smallest data communications networks. At one level,
routing and the configuration of routers are quite simple. But as internetworks grow in size and
complexity, routing issues can become at once both large and subtle. Perversely, perhaps, I am
grateful for the difficult problems large-scale routing can present—as a network systems consultant,
these problems are my bread and butter. Without them, the phrase You want fries with that? could
be an unfortunate part of my daily vocabulary....

As the Internet continues to grow exponentially, the need for network engineers to build, maintain,
and troubleshoot the growing number of component networks also has increased significantly.
Because network troubleshooting is a practical skill that requires on-the-job experience, it has
become critical that the learning curve necessary to gain expertise in internetworking technologies be
reduced to quickly fill the void of skilled network engineers needed to support the fast-growing
Internet. IP routing is at the core of Internet technology, and expedient troubleshooting of IP routing
failures is key to reducing network downtime. Reducing network downtime is crucial as the level of
mission-critical applications carried over the Internet...

Routing protocols make routers work together. Routers keep track of the networks they are
directly connected to, as well as other routers on the networks in order to forward packets to
foreign networks. A router maintains this info in its routing table and periodically shares
information from that table to other routers on the network. This info is used to determine the
best route for an incoming packet to take its destination.

VLAN Basics
如何在 1 个交换性的网络里,分割广播域呢?答案是创建 VLAN.VLAN 是连接到定义好了的
switch 的端口的网络用户和资源的逻辑分组.给不同的子网分配不同的端口,就可以创建更小
的广播域.默认情况下,在某个 VLAN 中的主机是不可以与其他 VLAN 通信的,除非你使用
router来创建 VLAN 间的通信

The Cisco Certified Internetwork Expert (CCIE) certification program has been available since
the early ’90s. This long-standing certification has maintained a high degree of credibility and
is recognized as a certification that lives up to the name “expert.” The CCIE certification process
requires passing a computer based test and then a two-day hands-on lab. Recertification is
required every two years to ensure that the individual has kept skills up-to-date.

Routers provide seperate collision domains.
B Switches create seperate collision domains and seperate broadcast
domains, Routers provide seperate collision domains and seperate
broadcast domain as well.

ATM is a packet-switched technology based on a 53-byte packet called a cell. Each
cell is divided into a 5-byte header and a 48-byte payload. The short, fixed length
cell reduces delay and jitter, allowing time sensitive information such as voice and
video to be transported along with data. There are various transmission media and
rates available with bandwidth measured in megabits to gigabits.
