1. 0:04hi
2. 0:04hello there welcome to apply methodology
3. 0:08to a design
4. 0:12this video introduces a network design
5. 0:15methodology
6. 0:16and presents guidelines for building an
7. 0:19effective network design solution
8. 0:21it includes the following sections the
9. 0:25cisco service oriented network
10. 0:26architecture
11. 0:28network design methodology identifying
12. 0:32customer requirements
13. 0:34characterizing the existing network and
14. 0:36sites
15. 0:37and using the top-down approach
16. 0:41to network design
17. 0:46the cisco service oriented network
18. 0:48architecture or sona
19. 0:50so this video lecture begins with an
20. 0:53introduction to the cisco vision of
21. 0:55intelligent networks
22. 0:56and the service oriented network
23. 0:59architecture
24. 1:00sona architectural framework so this
25. 1:03video lecture is not only intended for
26. 1:05cisco environment
27. 1:07okay so we will be just using this
28. 1:10architectural framework
29. 1:12on our network design so the life cycle
30. 1:15of the network
31. 1:16and a network design methodology based
32. 1:19on the lifecycle are presented
33. 1:22each phase of the network design process
34. 1:25is explored
35. 1:26in detail starting with how to identify
36. 1:30customer requirements including
37. 1:32organizational and technical goals and
38. 1:35constraints
39. 1:37because many customers build on existing
40. 1:39network
41. 1:40and at existing sites this video lecture
42. 1:43also presents
43. 1:44methods of characterizing that
44. 1:47existing network and those sites so a
45. 1:50top-down approach
46. 1:52to design and structure design
47. 1:54principles
48. 1:55is presented the design process includes
49. 1:59a discussion about
50. 2:00building a prototype or pilot
51. 2:03and appropriate content of a design
52. 2:06specification
53. 2:08so the video lecture concludes with a
54. 2:11discussion
55. 2:12of the design implementation process
56. 2:18the cisco service oriented network
57. 2:20architecture the extremely rich
58. 2:23variety of application level business
59. 2:25solutions available today
60. 2:27and the need to integrate these
61. 2:30applications
62. 2:31drives the need for a new network
63. 2:33architecture
64. 2:34this section introduces the cisco vision
65. 2:37and framework
66. 2:38that enable customers to build a more
67. 2:41intelligent
68. 2:42network infrastructure the cisco zone
69. 2:45architectural framework shifts
70. 2:47the view of the network from a pure
71. 2:50traffic transport-oriented view
72. 2:52towards a service and application
73. 2:54oriented view
74. 2:59cross-off applications so business
75. 3:02drivers
76. 3:03for a new network architecture new
77. 3:06business requirements
78. 3:07which are basically the growth of
79. 3:10applications
80. 3:11and the evolution of it combined to
81. 3:14drive the need
82. 3:14for a new network architecture in
83. 3:18today's business environment
84. 3:19intense competition and time to market
85. 3:22pressures are prompting enterprises to
86. 3:25look for new i.t solutions
87. 3:27that can help them better respond to
88. 3:29market and customers demand
89. 3:32so consumers are asking for new products
90. 3:35and service offerings
91. 3:36and they want them fast
92. 3:39so they are also demanding improved
93. 3:41customer service enhanced customization
94. 3:43flexibility
95. 3:45the greater security all of course at a
96. 3:48lower cost
97. 3:51i.t evolution from connectivity to
98. 3:54intelligent systems
99. 3:56so motor network connect multiple
100. 3:58resources and
101. 4:00information assets within the
102. 4:02organization
103. 4:03as well as provide access to external
104. 4:05resources
105. 4:07in this environment the iot model has
106. 4:10evolved
107. 4:11from mainframe to client server models
108. 4:15to internet applications as illustrated
109. 4:17here in the figure
110. 4:19so the cisco vision of the next space of
111. 4:22it evolution
112. 4:23is a real-time infrastructure that
113. 4:25integrates the network
114. 4:27and the applications as one system
115. 4:31so we've started with
116. 4:35terminal to mainframe connectivity and
117. 4:38then when the client server architecture
118. 4:40were introduced
119. 4:42you've got pocket networks you've got
120. 4:44the demand for networks to connect
121. 4:47multi-vendor devices and then
122. 4:51the evolution of the internet okay so
123. 4:54you've got pervasive
124. 4:55open networks enable client server to
125. 4:58extend beyond corporate boundaries
126. 5:01and there the tcp ip was introduced
127. 5:05until such time that we have this
128. 5:07real-time infrastructure
129. 5:09the network applications they work
130. 5:12together
131. 5:12as integrated systems via of course
132. 5:16the exchange of messages so
133. 5:19organizations are finding
134. 5:22that networking is no longer just about
135. 5:25connectivity
136. 5:26rather network intelligence is starting
137. 5:29to play a role
138. 5:30in improving business performance and
139. 5:32processes
140. 5:34intelligence enhances the network's role
141. 5:36as a foundation for enabling
142. 5:38communication
143. 5:39collaboration and business success
144. 5:44with increased awareness of the
145. 5:45applications that operate on the network
146. 5:47foundation
147. 5:49the network becomes an active
148. 5:50participant in applications
149. 5:52network management business systems and
150. 5:56services to enable them to work better
151. 6:00so the network is the common single
152. 6:02element that connects and enables
153. 6:04all components of the id infrastructure
154. 6:07so organizations need their networks
155. 6:11to evolve to intelligent systems that
156. 6:13participate actively in the delivery of
157. 6:16applications
158. 6:18to effectively reach the goal of
159. 6:20improving
160. 6:21productivity reducing time to market
161. 6:26greater revenue lower expenses
162. 6:29and stronger customer relationships so
163. 6:32an effective network provides the
164. 6:34foundation
165. 6:35for transforming business practices
166. 6:43new business requirement so the network
167. 6:46touches everything
168. 6:48evolving from connectivity to
169. 6:51intelligent systems
170. 6:53participate actively in the delivery of
171. 6:56applications and network services
172. 6:58and provide the foundation for
173. 7:01transforming business processes
174. 7:06traffic conditions in a converged
175. 7:07network
176. 7:09so modern network must support various
177. 7:11types of traffic
178. 7:13specifically you've got voice and video
179. 7:16traffic
180. 7:18voice application traffic the mission
181. 7:21critical traffic
182. 7:23transactional traffic network management
183. 7:26traffic
184. 7:28and routing protocol traffic so
185. 7:31this mix of traffic greatly impacts the
186. 7:34network requirements
187. 7:36such as security and performance so
188. 7:38security and performance
189. 7:41is a challenge to the network
190. 7:43administrator
191. 7:44systems administrators or network
192. 7:47managers
193. 7:48basically you have to balance security
194. 7:52and performance
195. 7:54so to help the enterprises cisco has
196. 7:57developed an intelligent
197. 7:59information network or the iim
198. 8:06cisco intelligent information network so
199. 8:09that is intelligence in the network
200. 8:11so integrating intelligence into the
201. 8:13network involves aligning
202. 8:15network and business requirements so to
203. 8:18accommodate today's and tomorrow's
204. 8:19network requirements
205. 8:21the model vision of the future includes
206. 8:24the intelligent information network
207. 8:26or iin so that is as a strategy
208. 8:30that addresses how the network is
209. 8:32integrated
210. 8:33with businesses and business priorities
211. 8:37so this vision encompasses the following
212. 8:39features
213. 8:41okay integration of network resources
214. 8:44and information assets that have been
215. 8:46largely unlinked
216. 8:49the modern converged network with
217. 8:51integrated voice
218. 8:52video and data required that it
219. 8:55departments
220. 8:56and other departments traditionally
221. 8:58responsible for other technologies
222. 9:00more closely link the ik infrastructure
223. 9:04with the network so also
224. 9:07intelligence across multiple products
225. 9:09and infrastructure layers
226. 9:11so the intelligence built to each
227. 9:14component on the network is extended
228. 9:18okay network wide and applies end-to-end
229. 9:22lastly active participation of the
230. 9:24network in the delivery of services and
231. 9:26applications
232. 9:29with added intelligence it is possible
233. 9:32for the network to actively manage
234. 9:35monitor and optimize services
235. 9:38and applications delivery across the
236. 9:40entire id environment
237. 9:43so basically the ii and technology
238. 9:45vision consists
239. 9:46of three paces you've got integrated
240. 9:49transport
241. 9:50integrated services and integrated
242. 9:53application
243. 9:55so the key point for intelligence in the
244. 9:57network would be
245. 9:59the intelligent network offers much more
246. 10:02than basic connectivity
247. 10:04so bandwidth for users and access to
248. 10:07applications
249. 10:09it offers an end-to-end functionality
250. 10:11and centralized
251. 10:13unified control that promotes true
252. 10:16business
253. 10:16transparency and agility
254. 10:20so as mentioned earlier the intelligence
255. 10:23or the iin
256. 10:24comprises of three paces
257. 10:28so pace one is integrated transport
258. 10:32so everything data voice
259. 10:36and video consolidates onto an ip
260. 10:39network for secure
261. 10:40network convergence so by integrating
262. 10:43data voice and video transport into a
263. 10:46single standard
264. 10:47based modular network organizations can
265. 10:50simply
266. 10:51network management and generate
267. 10:54an enterprise-wide efficiencies
268. 10:58phase two integrated services when the
269. 11:02network infrastructure is converged
270. 11:04id resources can be pulled and shared or
271. 11:08virtualized to flexibly address
272. 11:12the changing needs of the organization
273. 11:14so by extending this virtualization
274. 11:16concept
275. 11:17to encompass server storage
276. 11:21and network elements an organization
277. 11:24can transparently use all of its
278. 11:26resources efficiently
279. 11:29so business continuity is also enhanced
280. 11:32because in the event of local systems
281. 11:34failure
282. 11:35shared resources across the intelligent
283. 11:38network
284. 11:38can provide needed services
285. 11:42and phase 3 integrated applications
286. 11:47so this phase focuses on making the
287. 11:50network application aware
288. 11:52so that it can optimize application
289. 11:54performance and
290. 11:55more efficiently deliver network
291. 11:58applications to users
292. 12:00so in addition to capabilities such as
293. 12:02content caching
294. 12:04load balancing and application level
295. 12:06security
296. 12:08application network services make it
297. 12:10possible for the network
298. 12:12to simplify the application and
299. 12:14infrastructure
300. 12:16by integrating intelligent application
301. 12:18message handling
302. 12:20optimization and security into the
303. 12:23existing
304. 12:24network
305. 12:29the cisco sona is an architectural
306. 12:31framework
307. 12:32that illustrates how to build integrated
308. 12:35systems
309. 12:36and guides the evolution of enterprises
310. 12:38towards
311. 12:39more intelligent networks so using sona
312. 12:43framework
313. 12:44enterprises can improve flexibility
314. 12:47and increase efficiency by optimizing
315. 12:50applications
316. 12:52business processes and resources
317. 12:56to enable it to have a greater effect
318. 12:59on business so the sauna framework
319. 13:02leverages
320. 13:03the extensive product line services
321. 13:06proven architectures
322. 13:07and experience of cisco and its
323. 13:11partners to help enterprises achieve
324. 13:14their
325. 13:14business goals so that's what i have
326. 13:16mentioned earlier
327. 13:17this is not just applicable for
328. 13:20cisco equipment and cisco products we
329. 13:23can apply
330. 13:24the framework even though we are using
331. 13:27enan cisco devices
332. 13:33cisco sona framework layers
333. 13:36the sona framework as shown here in the
334. 13:37figure shows how integrated systems can
335. 13:40allow a dynamic
336. 13:42flexible architecture and provide for
337. 13:44operational efficiency
338. 13:46through standardization and
339. 13:48virtualization
340. 13:50so the key point for the sauna framework
341. 13:53layer would be
342. 13:54in the sonar framework the network is
343. 13:57the common element that connects
344. 13:59and enables all components of the id
345. 14:02infrastructure
346. 14:03so the sonar framework defines the
347. 14:05following three layers here
348. 14:07okay you've got the network
349. 14:09infrastructure layer
350. 14:11interactive services layer and
351. 14:13application layer
352. 14:17network infrastructure layer
353. 14:20so this layer provides connectivity
354. 14:24anywhere and anytime
355. 14:27so where all the id resources are
356. 14:29interconnected across a converged
357. 14:31network foundation so the id resources
358. 14:35includes
359. 14:36servers storage and clients
360. 14:40so the network infrastructure layer
361. 14:42represents
362. 14:43how these resources exist in different
363. 14:46places in the network
364. 14:47including the campus branch data center
365. 14:51enterprise edge one metropolitan area
366. 14:55network or man and with the
367. 14:58consideration of having
368. 15:00a teleworker and organization so the
369. 15:03objective of this layer is to provide
370. 15:05connectivity
371. 15:06anytime anywhere so the network
372. 15:10infrastructure layer includes the
373. 15:12network devices and links
374. 15:14to connect servers storage and
375. 15:17clients in different places in the
376. 15:20network
377. 15:23so the next layer would be the
378. 15:24interactive services layer
379. 15:27so this includes both application
380. 15:30and networking services together with
381. 15:33infrastructure services
382. 15:36so this layer enables efficient
383. 15:38allocation of resources to applications
384. 15:40and business processes
385. 15:42delivered through the network
386. 15:44infrastructure
387. 15:46so this layer includes the following
388. 15:48services here
389. 15:49you've got voice and collaboration
390. 15:51services
391. 15:53okay mobility services wireless services
392. 15:57security and identity services storage
393. 16:00services
394. 16:02computing services application
395. 16:06networking services content networking
396. 16:09services
397. 16:10okay uh network infrastructure
398. 16:13virtualization
399. 16:15adaptive network management services
400. 16:18the quality of service is an important
401. 16:20thing here qos
402. 16:22and of course the high availability
403. 16:28last one would be the application layer
404. 16:30so this
405. 16:31layer includes business applications and
406. 16:34collaboration applications
407. 16:36so the objective of this layer is to
408. 16:39meet business requirements
409. 16:41and achieve efficiencies by leveraging
410. 16:44the
411. 16:45interactive services layer so this
412. 16:48layer includes the following
413. 16:50collaborative applications
414. 16:52so you've got commercial applications
415. 16:55internally developed applications
416. 16:59software as a service or the sas and
417. 17:02the composite apps
418. 17:08so what are the benefits of sauna
419. 17:11including
420. 17:13this in the organization's planning so
421. 17:16basically sona provides
422. 17:19functionality okay supports
423. 17:22the organizational requirements another
424. 17:25is scalability
425. 17:27supports growth and expansion of the
426. 17:30organizational task
427. 17:32by separating functions and products
428. 17:34into layers
429. 17:35so this separation makes it easier to
430. 17:38grow the network
431. 17:40you also have availability
432. 17:43so provides the necessary services
433. 17:46reliably
434. 17:47anywhere anytime performance
435. 17:51provides the desired responsiveness
436. 17:54throughput
437. 17:55and utilization on a per application
438. 17:59basis
439. 18:00through the network infrastructure and
440. 18:02services
441. 18:03next would be manageability so provides
442. 18:07control performance monitoring and fault
443. 18:10detection
444. 18:12efficiency is also a factor provides the
445. 18:15required network services
446. 18:17and infrastructure with reasonable
447. 18:19operational costs
448. 18:21and appropriate capital investment on a
449. 18:23migration path
450. 18:25to a more intelligent network that is
451. 18:28via step-by-step network services
452. 18:31growth and another one
453. 18:34is not listed here which is security
454. 18:37provides for an effective balance
455. 18:39between usability and security while
456. 18:42protecting information assets and
457. 18:44infrastructure from inside and outside
458. 18:47threats
459. 18:52so let us summarize the cisco service
460. 18:55oriented network architecture
461. 18:58so drivers for a new network
462. 18:59architecture includes
463. 19:01just factors so basically we covered
464. 19:04growth of applications the id evolution
465. 19:08from connectivity to intelligent systems
466. 19:11and the increased business expectation
467. 19:13for
468. 19:14networks so cisco's vision of
469. 19:17intelligence in the network aligns
470. 19:19network and business requirements in
471. 19:22three places
472. 19:24so you've got integrated transport
473. 19:26integrated services
474. 19:28and integrated applications
475. 19:31the cisco sona is the enterprise
476. 19:34framework for building intelligence in
477. 19:36the network so we covered
478. 19:39layer 1.3 so layer 1 is the integrated
479. 19:42infrastructure layer
480. 19:44layer 2 is the interactive services
481. 19:46layer
482. 19:47and layer 3 is the application layer
