标题: 网络延时和丢包问题
我们单位接入的是10M光纤,内部大概有差不多1000个用户,网络结构是电信进来接cisco3845路由器,再接cisco pix525防火墙(做内网的NAT和服务器的DMZ),再接cisco 4507交换机做核心,下接cisco2590做接入,内网用户划分了3个vlan,现在感觉网络特别慢.延时都在200多ms,而且丢包也很严重,有10%左右.查看了一下路由器的接口情况,如下:\r\nGigabitEthernet0/0 is up, line protocol is up(内网口)\r\n Hardware is BCM1125 Internal MAC, address is 0015.2bd6.f3c0 (bia 0015.2bd6.f3c\r\n0)\r\n Internet address is *.*.*.*/26\r\n MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,\r\n reliability 255/255, txload 1/255, rxload 2/255\r\n Encapsulation ARPA, loopback not set\r\n Keepalive set (10 sec)\r\n Full-duplex, 1000Mb/s, link type is autonegotiation, media type is RJ45\r\n output flow-control is XON, input flow-control is XON\r\n ARP type: ARPA, ARP Timeout 04:00:00\r\n Last input 00:00:00, output 00:00:00, output hang never\r\n Last clearing of \"show interface\" counters never\r\n Input queue: 0/75/23/0 (size/max/drops/flushes); Total output drops: 0\r\n Queueing strategy: fifo\r\n Output queue: 0/40 (size/max)\r\n 5 minute input rate 10330000 bits/sec, 1525 packets/sec\r\n 5 minute output rate 3636000 bits/sec, 1334 packets/sec\r\n 1209953066 packets input, 882173012 bytes, 0 no buffer\r\n Received 0 broadcasts, 1 runts, 0 giants, 0 throttles\r\n 0 input errors, 24 CRC, 0 frame, 0 overrun, 0 ignored\r\n 0 watchdog, 449323 multicast, 0 pause input\r\n 0 input packets with dribble condition detected\r\n 1027355111 packets output, 1344887171 bytes, 0 underruns\r\n 7 output errors, 0 collisions, 2 interface resets\r\n 0 babbles, 0 late collision, 0 deferred\r\n 7 lost carrier, 0 no carrier, 0 pause output\r\n 0 output buffer failures, 0 output buffers swapped out\r\nGigabitEthernet0/1 is up, line protocol is up(外网口)\r\n Hardware is BCM1125 Internal MAC, address is 0015.2bd6.f3c1 (bia 0015.2bd6.f3c\r\n1)\r\n Internet address is *.*.*.*/30\r\n MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec,\r\n reliability 255/255, txload 248/255, rxload 92/255\r\n Encapsulation ARPA, loopback not set\r\n Keepalive set (10 sec)\r\n Full-duplex, 10Mb/s, link type is autonegotiation, media type is RJ45\r\n output flow-control is XON, input flow-control is XON\r\n ARP type: ARPA, ARP Timeout 04:00:00\r\n Last input 00:00:03, output 00:00:00, output hang never\r\n Last clearing of \"show interface\" counters never\r\n Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 49276528\r\n Queueing strategy: fifo\r\n Output queue: 40/40 (size/max)\r\n 5 minute input rate 3647000 bits/sec, 1335 packets/sec\r\n 5 minute output rate 9731000 bits/sec, 1369 packets/sec\r\n 1027370252 packets input, 3182616081 bytes, 0 no buffer\r\n Received 0 broadcasts, 0 runts, 0 giants, 0 throttles\r\n 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored\r\n 0 watchdog, 507422 multicast, 0 pause input\r\n 0 input packets with dribble condition detected\r\n 1160623596 packets output, 3541149476 bytes, 0 underruns\r\n 3 output errors, 0 collisions, 3 interface resets\r\n 0 babbles, 0 late collision, 0 deferred\r\n 3 lost carrier, 0 no carrier, 0 pause output\r\n 0 output buffer failures, 0 output buffers swapped out\r\n\r\n其中内口reliability 255/255, txload 1/255, rxload 2/255\r\n而外网口reliability 255/255, txload 248/255, rxload 92/255\r\n这是怎么回事?\r\n大家帮忙分析一下.除了这个还会有什么问题吗?

你的10M已经满了,所以慢
