為持續擴大與神腦國際股份有限公司(2450)業務合作及雙方策略聯盟關係,中華電信(2412)98年3月27董事會決議參與認購神腦國際股份有限公司私募普通股48,000千股。在參與認購上述私募普通股後,中華電信對神腦國際的持股比例將增加為40.8%

中華電信ADSL費用比日本便宜

有關消基會發佈「以日本YAHOO!BBADSL費用來說,只需要165日幣的電路費予NTT東日本,換算台幣僅需56元」乙節,中華電信表示經查日本YAHOO!BBNTT租用部分銅絞線用戶迴路之租金為165日幣,而非ADSL電路費。以日本YAHOO!BBADSL 8M為例,日本用戶必須繳交的ADSL費用為ADSL電路月租費(1039日幣)、數據機月租費(724日幣)及用戶迴路租金(165日幣),合計1928日幣,折合台幣656元;另以日本NTTADSL8M為例,電路月租費3297日元,折合台幣1141元,顯示中華電信ADSL8M電路月租費僅500元,實較日本便宜。此外,除ADSL電路月租費較日本便宜外,如以相同速率8M比較,中華電信電路及上網月租費合計999元,低於日本YAHOO!BB費用3366日幣(折合台幣1144

中華電信表示為提昇寬頻普及率,降低寬頻入門門檻,提256K/64K服務,入門費率全球最低,每月電路加計上網租費僅為309元。若NCC通過本年度中華電信ADSL資費調降及免費升速案,將嘉惠參百多萬客戶,資費將更為便宜。

中華電信入股台灣碩網 打造寬頻新世紀

發布日期:98318

中華電信入股台灣碩網,打造寬頻新世紀!

- 共同推展高畫質影音娛樂內容與光纖寬頻服務 -

中華電信股份有限公司與日本Sony集團旗下之網際網路服務事業So-net Entertainment Taiwan (台灣碩網網路娛樂股份有限公司)今日簽署投資協議,中華電信參與So-net現金增資,取得百分之三十的股權,未來,雙方將共同致力於推展高畫質影音娛樂內容與快速增長的光纖寬頻服務。

高畫質影音內容的普及已是全球化趨勢,在日本普及率約60%,中華電信與So-net藉由雙方集團資源的結合,致力於拓展台灣高畫質影音娛樂市場,提供人人皆可輕鬆享受的高畫質影音娛樂。

拓展高畫質影音娛樂市場

近年來,全球影音娛樂需求快速增加,HDTV的市場滲透率亦日漸普及,中華電信則以MOD服務積極拓展台灣的高畫質影音娛樂市場,目前,已有近七十萬MOD用戶可以欣賞高品質的影音服務。

中華電信在入股之後,將於四月份起於中華電信服務中心設置MOD體驗區(HD Square) ,藉由結合Sony BRAVIA高畫質電視與So-net FTTB光纖服務,展示高畫質影音的精采內容。

推廣光纖寬頻服務

目前,台灣的光纖用戶數已超越百萬戶,光纖市場正急速成長中,預計在99年,光纖用戶數可望佔有寬頻市場的過半數。中華電信與So-net將透過行銷與服務的密切合作共同推動及掌握光纖寬頻服務商機。

合作提供數位內容與加值服務

中華電信總經理張曉東指出,除了光纖寬頻服務的合作外,So-net Japan 在數位內容與加值服務的經營極為出色,而此一部份正是中華電信目前較缺乏的一環,未來,透過雙方的合作架構,可望引進So-net Japan的數位內容與加值服務,提供中華電信消費者更優質、更多元化的服務,創造多贏的合作效益

So-net台灣執行長石井隆一指出:So-net經營台灣市場近八年,向來以提供優質寬頻服務與獨特的娛樂內容自許,如近年來推出的電郵寵物PostPet服務等,相信與中華電信的合作將帶給So-net寬頻服務會員更完善的服務品質。

中華電信引進Femto cell微型家用3G基地台一案

對於中華電信引進Femto cell微型家用3G基地台一案,主管國內基地台認證、管理的NCC表示同意先讓中華電信先以小規模方式實驗。

由於Femto cell在全球電信市場還是新興通訊技術,包括規格、基地台干擾性都還不確定,因此NCC傾向讓有意引進該技術的中華電信,先以小規模方式實驗。待實驗確定不會對其他3G業者訊號產生干擾後,再決定是否准予中華電信大量導入Femto cell。

Femto cell可將家中ADSL網路轉換為室內3G訊號,以改善原本用戶家中3G訊號不良問題,讓3G用戶不論室內、室外均能無縫使用3G上網。與一般手機基地台發射功率從數瓦到數百瓦相比,Femto cell因功率只有100毫瓦以內(低於0.1瓦),因此體積比基地台小,大小與書本相當,不僅功率適合小範圍的住家使用,因體積小也易於安裝在住家中。

在NCC立場較明確後,中華電信已開始著手引進Femto cell的計劃。據瞭解,目前中華電信已確定採用Alcatel-Lucent的方案,採購包括Femto Gateway、Access Point、服務路由器及所需管理系統。

在中華電信準備著手實驗後,也將成為全球繼Verizon、SoftBank後第三家導入Femto cell的電信業者,並成為國內其他電信業者注目的焦點。不過,也許是進入重要的實驗導入階段,以及擔心競爭對手瞭解其導入策略。相較於過去中華電信高談闊論,中華電信目前對引進Femto cell顯得低調且小心翼翼。

中華電信行通公司協理石木標表示,中華電信對Femto cell的引進相當看好,但目前無法對引進規模、何時開始服務用戶作說明。

不過,若年底至明年初開始實驗後,預期明年會是決定Femto cell大量引進的時機,若中華電信率先其他電信業者導入,將可協助其3G用戶解決家中訊號涵蓋不足問題,使其以固網資源彌補行動資源之不足,對其降低3G網路基礎建設成本也有助益。今年底中華電信3G用戶數將達到約320萬用戶,約佔其行動用戶總數的三分之一強。

相較之下,目前國內其他行動電信業者仍對Femto cell持觀望的態度,其中和中華電信引進Femto cell技術,準備利用旗下龐大的ADSL、光纖等寬頻固網資源提昇3G行動網路涵蓋率相反,遠傳則利用戶外3.5G訊號接取到用戶家中轉換為固網頻寬,用以取代ADSL市場,電信市場競爭開始進入固網、行動資源整合FMC另一新戰場。

Hot Standby Router Protocol (HSRP): Frequently Asked Questions

                                                                 
Introduction
This document addresses the most frequently asked questions related to Hot Standby Router Protocol (HSRP).
 
 
 
Q. Will the standby router take over if the active router LAN interface state is "interface up line protocol down"?
A. Yes, the standby router takes over once the holdtime expires. By default, this equals to three hello packets from the active router having been missed. The actual convergence time depends on the HSRP timers configured for the group and possibly on routing protocol convergence. The HSRP hellotime timer defaults to 3 and the holdtime timer defaults to 10.
 
 
 
Q. Can I configure more than one standby group with the same group number?
A. Yes. However, Cisco does not recommend it on lower-end platforms such as the 4x00 series and earlier. If the same group number is assigned to multiple standby groups, it creates a non-unique MAC address. This is seen as the router's own MAC address and it is filtered out if more than one router in a LAN becomes active. This behavior may change in future releases of Cisco IOSR.
 
Note: 4x00 series and earlier do not have the hardware required to support more than one MAC address at a time on Ethernet interfaces. However, the Cisco 2600 and Cisco 3600 do support multiple MAC addresses on all Ethernet and Fast Ethernet interfaces.
 
 
 
Q. When an active router tracks serial 0 and the serial line goes down, how does the standby router know to become active?
A. When a tracked interface's state changes to down, the active router decrements its priority.
 
The standby router reads this value from the hello packet priority field, and becomes active if this value is lower than its own priority and the standby preempt is configured. You can configure by how much the router should decrement the priority. By default, it decrements its priority by 10.
 
 
 
Q. If there is no priority configured for a standby group, what determines which router is active?
A. The priority field is used to elect the active router and the standby router for the specific group. In the case of an equal priority, the router with the highest IP address for the respective group is elected as active. Furthermore, if there are more than two routers in the group, the second highest IP address determines the standby router and the other router/routers are in the listen state.
 
Note: If no priority is configured it uses the default of 100.
 
 
 
Q. What are the limiting factors that determine how many standby groups can be assigned to a router?
A. Ethernet: 256 per router. FDDI: 256 per router. Token Ring: 3 per router (uses reserved functional address).
 
Note:4x00 series and earlier do not have the hardware required to support more than one MAC address at a time on Ethernet interfaces. However, the Cisco 2600 and Cisco 3600 do support multiple MAC addresses on all Ethernet and Fast Ethernet interfaces.
 
 
 

Q. Which HSRP router requires that I configure preempt?
A. An HSRP-enabled router with preempt configured attempts to assume control as the active router when its Hot Standby priority is higher than the current active router. The standby preempt command is needed in situations when you want an occurring state change of a tracked interface to cause a standby router to take over from the active router. For example, an active router tracks another interface and decrements its priority when that interface goes down. The standby router priority is now higher and it sees the state change in the hello packet priority field. If preempt is not configured, it cannot take over and failover does not occur.
 
 
 
Q. From reading the documentation it looks like I can use HSRP to achieve load-balancing across two serial links. Is this true?
A. Yes, refer to Load Sharing with HSRP for more information.
 
 
 

Q. Does HSRP support DDR, and if so, how will it know to dial?
A. No, HSRP does not support Dial-on-Demand Routing (DDR) directly. However, you can configure it to track a serial interface and swap from the active to the standby router in case of a WAN link failure. The command used to track the state of an interface is standby track
 
 
 
Q. I am using HSRP and all hosts are using the active router to forward traffic to the rest of my network. I have noticed that the return traffic comes back through the standby router. Will this cause problems with HSRP or my applications?
A. No, normally this is transparent to all hosts and/or servers on the LAN and can be desirable if a router experiences high traffic. You can change this by configuring a more desirable cost for the link you would like the distant router/routers to use.
 
 
 

Q. How does DECnet traffic fit into the HSRP scenario?
A. DECnet and XNS are compatible with HSRP and multiple HSRP (MHSRP) over Ethernet, FDDI, and Token Ring on the Cisco 7000 and Cisco 7500 routers only. For more information, refer to Using HSRP for Fault-Tolerant IP Routing.
 
 
 
Q. Can a Cisco 2500 and Cisco 7500 router on the same LAN segment use HSRP, or do I have to replace one of the routers so the platforms are identical?
A. You can mix the platforms with HSRP, but you are not able to support multiple HSRP (MHSRP) due to the hardware limitations of the lower-end platform.
 
 
 
Q. If I use a switch, what do I see on the CAM tables for the HSRP?
A. The content-addressable memory (CAM) tables provide a map for the HSRP MAC address to the port on which the active router is located. In this way, you can determine what the switch perceives the HSRP status to be.
 
 
 
Q. What is the standby use-bia command and how does it work?
A. By default, HSRP uses the preassigned HSRP virtual MAC address on Ethernet and FDDI, or the functional address on Token Ring. To configure HSRP to use the interface's burnt-in address as its virtual MAC address, instead of the default, use the standby use-bia command.
 
For example, on Token Ring, if Source Route Bridging is in use, a Routing Information Field (RIF) is stored with the virtual MAC address in the host's RIF cache. The RIF indicates the path and final ring used to reach the MAC address. As routers transition to the active state, they send gratuitous Address Resolution Protocols (ARPs) in order to update the host's ARP table. However, this does not affect the RIF cache of the hosts that are on the bridged ring.
 
This situation can lead to packets being bridged to the ring for the previous active router. To avoid this situation, use the standby use-bia command. The router now uses its burnt-in MAC address as the virtual MAC address.
 
Note: Using the standby use-bia command has these disadvantages:
 
 
 
When a router becomes active the virtual IP address is moved to a different MAC address. The newly active router sends a gratuitous ARP response, but not all host implementations handle the gratuitous ARP correctly.
 
Proxy ARP breaks when use-bia is configured. A standby router cannot cover for the lost proxy ARP database of the failed router.
Q. Can I run NAT and HSRP together?
A. You can configure network address translation (NAT) and HSRP on the same router. However, a router that runs NAT holds state information for traffic that is translated through it. If this is the active HSRP router and the HSRP standby takes over, the state information is lost.
 
Note: Stateful NAT (SNAT) can make use of HSRP to fail over. For more information, refer to NAT Stateful Failover of Network Address Translation. Static NAT Mapping Support with HSRP for High Availability is another feature which makes NAT and HSRP interact. For more information refer to NATStatic Mapping Support with HSRP for High Availability.
 
 
 
Q. What are the IP source address and destination address of HSRP hello packets?
A. The destination address of HSRP hello packets is the all routers multicast address (224.0.0.2). The source address is the router's primary IP address assigned to the interface.
 
 
 
Q. Are HSRP messages TCP or UDP?
A. UDP, since HSRP runs on UDP port 1985.
 
 
 
Q. HSRP stops working when an Access Control List (ACL) is applied. How can I permit HSRP through an ACL?
A. HSRP hello packets are sent to multicast address 224.0.0.2 using UDP port 1985. Whenever an ACL is applied to an HSRP interface, ensure that packets destined to 224.0.0.2 on UDP port 1985 are permitted.

HSRP(Hot Standby Routing Protocol)

 
 
 
一、HSRP(Hot Standby Routing Protocol)
(一)原理:
兩台或多台ROUTER配置成cluster,創造出單一虛擬路由器virtual router,客戶端將gateway指向virtual router,最後由HSRP再決定那個router為real default gateway。

HSRP每隔3秒發送hello包,依據優先級最高的路由器是active router,如果優先級相同,在IP地址高的成為active router。


HSRP組中,只允許同時存在一個active router,其他路由器都處於standby狀態,standby router不轉發數據包。

當standby router一直收到active router發來的hello包,就會一直處於standby狀態。一旦備用路由器在規定的時間內(Hold Time,預設10)沒有收到hello包,則認為active router失效,優先級最高的備用路由器就接替活動路由器的角色,開始轉發數據包。

(二)技術
1.preempt
active router失效後,優先級最高的備用路由器會變成活動狀態,如果沒有使用preempt技術,則當active router恢復後,只能處於備用狀態,先前的備用服務器代替其角色處於活動狀態,直到下一次選舉發生。

2.track
一般使用HSRP時,兩顆router其中一棵router掛掉,才會切換成standby的router運作。track的好處是,可以同時track多個介面,當有一介面DOWN時(或當對內switch接口斷掉時),則切換成standby router接手。

(三)配置
routerA#conf t
routerA(config)#int e0
routerA(config)#standby ip 172.16.1.254
routerA(config)#standby preempt
routerA(config)#standby track serial 0
routerA(config)#exit
routerA#


HSRP與GLBP兩種皆有備援機制,但是GLBP算是比較新的應用,兩顆router可以同時運作active,做load-sharing。HSRP則是兩顆rorter其中一顆當active,另外一顆當standby,當然其中一顆loading值會較高。

其實目前應用來說GLBP在C/P值當中還是比較高,應用限制呢就還需要再觀察囉。

中華電信表示採單一話價應在市話資費合理化下進行

對於消基會於226表示台灣應取消長途電話費率,實施台澎金馬單一話價乙案,中華電信公司表示,單一話價應在市話資費合理化下進行,另有關該會所稱國際電話費率低於長途電話費乙節,係因該公司春節期間對部分地區的短期促銷費率,並非全面適用。

中華電信公司網路建設遍及全國,大部分電信設施逾齡均汰舊換新,因此,該公司表示為提供良好的通信品質及客戶更好的服務,每年均持續對固網機線設備進行投資建設及維護,每年折舊費用高達數百億元,投資相當龐大。而市內電話在早期政府普及政策的考量下,採取低於成本的低月租費及低通信費,目前面臨行動電話的替代效應,市內電話已處於虧損狀態,如資費無法合理化,實無實施單一話價之空間。

消基會所稱比利時為例,土地面積與台灣接近,未區分市話及長途兩種話費,然其話費每分鐘高達1.62.24元,收費高於我國市內及長途電話費。

中華電信公司表示,消基會提出的美、日、大陸三國,美國以分計價,大陸以每6秒計價,日本比較複雜,有以分、以90秒等單位計價,而該公司以秒計價,是「實講實收」,不像他國即使講不到1分鐘也得以分計價,計價上十分合理,因此對於消基會統一以「每分鐘」比較,有失公平。
