标题: 华为三层交换机s5516应该做哪些优化可以提高带宽?
公司做的校园网,采用华为的设备构建起基网,在基网的基础上各个教室安装了终端设备,教室采用竞业达的终端设备进行一些视频点播,前面用的是VCD的影片多个教室点播时网络还能承受,但昨天在服务器上上传了一些DVD影片,在点播时发现有些教室画面有停滞的现象,我想优化一下网络,可不知道该优化哪些方面,请各位高手指点一二!

对，用qos，把vod的优先级放在前面。

本例中才用LLQ来实现Video的QoS 中心点 : Router 1(7507) In between router : Router 2(3640) Remote side : Router 3(2620) 中心点: Router 1 class-map match-all OFIS_TO_MCU match access-group 100 class-map match-all MCU_TO_OFIS match access-group 101 ! policy-map TO_MCU //定义LLQ策略 class OFIS_TO_MCU priority 1518 //定义为Video预留的带宽，注意要在视频带宽基础上加上25%的开销 set ip precedence 5 class class-default fair-queue policy-map TO_OFIS class MCU_TO_OFIS priority 1518 set ip precedence 5 class class-default fair-queue ! interface FastEthernet1/0/0 no ip address no ip route-cache distributed full-duplex ! interface FastEthernet1/0/0.1 description HQ1 LAN encapsulation dot1Q 1 ip address 129.2.80.21 255.255.0.0 service-policy output TO_MCU //在接口下应用策略 ! interface Serial1/0/0 description Router 1 to ROUTER 2 ip address 206.141.24.1 255.255.255.0 ip route-cache policy no ip route-cache distributed service-policy output TO_OFIS ! access-list 100 permit ip host 141.2.20.20 host 129.2.20.34 precedence critical//通过ACL匹配来激活策略 access-list 101 permit ip host 129.2.20.34 host 141.2.20.20 precedence critical ! ------------------------------------------------------------------------------------------------- In between router : Router 2 class-map OFIS_TO_MCU match access-group 100 class-map MCU_TO_OFIS match access-group 101 ! ! policy-map TO_MCU class OFIS_TO_MCU priority 1518 class class-default fair-queue policy-map TO_OFIS class MCU_TO_OFIS priority 1518 class class-default fair-queue ! interface Serial2/0 description Router 2 to Router 1 bandwidth 2048 ip address 206.141.24.2 255.255.255.0 no ip directed-broadcast ip route-cache policy no ip mroute-cache service-policy output TO_MCU ! interface Serial2/1 description Router 2 to Router 3 bandwidth 2048 ip address 218.141.2.1 255.255.255.0 no ip directed-broadcast ip route-cache policy service-policy output TO_OFIS ! access-list 100 permit ip host 141.2.20.20 host 129.2.20.34 precedence critical access-list 101 permit ip host 129.2.20.34 host 141.2.20.20 precedence critical ---------------------------------------------------------------------------------------------------- Remote side : Router 3 class-map OFIS_TO_MCU match access-group 100 class-map MCU_TO_OFIS match access-group 101 ! ! policy-map TO_MCU class OFIS_TO_MCU priority 1518 class class-default fair-queue policy-map TO_OFIS class MCU_TO_OFIS priority 1518 class class-default fair-queue ! interface FastEthernet0/0 ip address 141.2.81.20 255.255.0.0 no ip directed-broadcast ip route-cache policy speed 100 full-duplex ! interface Serial0/0 description Router 3 To Router 2 bandwidth 2048 ip address 218.141.2.2 255.255.255.0 no ip directed-broadcast ip route-cache policy no ip mroute-cache service-policy output TO_MCU ! access-list 100 permit ip host 141.2.20.20 host 129.2.20.34 precedence critical access-list 101 permit ip host 129.2.20.34 host 141.2.20.20 precedence critical
