1 A WWW Server Benchmark System in IPv6 Environment Takao Nakayama Graduate School of Information Science Nara Institute of Science and Technology
2 Background(/2) With the spread of IPv6 technology, we can use various services in IPv6 Many ISPs are beginning to offer IPv6 services WWW, Mail, IRC Measurement in IPv6 is needed Network administrator have accumulated much know-how Whether the know-how can be applied for IPv6? 2
3 Background(2/2) We focus WWW server Most important service in the Internet Measurement system of WWW server Kernel monitoring system Packet monitoring system Benchmark system Can these systems be applied in IPv6? 3
4 Kernel monitoring system Collect information in the kernel Virtual memory statistics CPU activity Kernel I/O statistics Common UNIX systems have program that reports above parameters These parameters are independent of network This method can be applied in IPv6 4
5 Packet monitoring system (/2) Monitoring the packets that go the WWW server in and out This method does not cause the performance degradation The server scale and OS are independent This method can measure the server in operation 5
6 Packet monitoring system (2/2) Packet monitoring tool for WWW Tcpdump General packet monitoring tool Many log analysis tools ENMA Specialized in WWW developed by our research group Packet capture library can capture an IPv6 packet This method can be applied in IPv6 6
7 Benchmark system(/2) Benchmark system can make clear performance indices of WWW server Connection continuation time Throughput Connection establishment time Typical benchmark system Httperf SPECweb Webstone 7
8 Benchmark system(2/2) Typical benchmark systems are not support IPv6 We develop a new benchmark system We named our benchmark system ANMA (Active Network Measurement Agent) 8
9 Requirements of benchmark system in IPv6 Requests of both IPv6 and IPv4 can be sent Request rate of IPv6 and IPv4 can be specified Statistics data are outputted about both of IPv6 and IPv4 9
10 How to create requests NIC has two or more addresses ANMA reads address list file Get address family by getaddrinfo() ANMA sends requests Read address is IPv6 IPv6 request is send Read address is IPv4 IPv4 request is send Address list 3ffe:50:808:403:: ffe:50:808:403:: ffe:50:808:403::3 3ffe:50:808:403:: Read address list Read address list Source address Source address ANMA IPv6 IPv4 request request IPv6 request WWW Server 0
11 How to control the ratio of requests The ratio of IPv6 and IPv4 in address list The ratio of requests Address list 3ffe:50:808:403:: 3ffe:50:808:403::2 3ffe:50:808:403::3 3ffe:50:808:403::4 3ffe:50:808:403::5 3ffe:50:808:403:: IPv6 requests : IPv4 requests = 3 : Address list ffe:50:808:403:: 3ffe:50:808:4032::2 IPv6 requests : IPv4 requests = : 3
12 Time to record Performance indices about a period of time Connection establishment time Connection continuation time Connection Continuation Time connection establishment time client server SYN ACK GET SYN +ACK FIN ACK FIN ACK Each time is measured with gettimeofday() 2
13 Connection data Types of connection closed status NORMAL closed Demanded file is received normally RESET closed Connection is reset from server TIMEOUT closed Connection continues for 5 seconds When the load of WWW server is high, the number of RESET and TIMEOUT is increased 3
14 Implementation of ANMA Platform FreeBSD Parameters IP address of target WWW server Target file name The number of total requests The number of concurrent connections ANMA reports Avg. of connection continuation time Avg. of connection establishment time Statistics of connection data 4
15 Experiment Machine spec Pentium-III 800MHz 256MB memory FreeBSD-4.7 Experiment network client client2 client3 ANMA requests router Target WWW Apache IPv6 unofficial patch 5
16 Experiment Configuration parameter Target file size : 4kbytes Total requests : 0,000 Concurrent connections :,000 The ratio of IPv6 and IPv4 : 5 patterns (A) IPv6 : IPv4 = : (B) IPv6 : IPv4 = 4 : (C) IPv6 : IPv4 = : 4 (D) IPv6 : IPv4 = : 0 (E) IPv6 : IPv4 = 0 : 6
17 Result (connection data) A B C D E Ratio of IPv6 : IPv Sent request IPv6 5,000 8,00 2,00 0,000 0 IPv4 5,000,999 7, ,000 # of NORMAL IPv6 4,536 7,276,85 9,064 0 IPv4 4,537,822 7, ,993 # of RESET IPv Request is sent at the specified ratio Rate of RESET is about 0% WWW server is in normal state by our precedence research Takao Nakayama, Yutaka Nakamura, and Hideki Sunahara. `The Real-Time State Observation System for WWW Server.'. In INET2002, (2002-Jun). 0 IPv ,007 7
18 Result (time data) A B C D E Ratio of IPv6 : IPv Avg. connection establishment (us) IPv IPv Avg. connection continuation (ms) IPv IPv Each result is independent of the ratio of IPv6 and IPv4 Connection continuation time IPv6 2.7msec, IPv4.8msec Connection establishment time IPv6 0usec, IPv4 usec 8
19 Future work Requests transmission by SSL Control of a request transmission rate processing rate is one of the performance indices Consideration of Dynamic contents Consideration of network delay To construct an experimental network near to the actual environment dummynet is often used for implementation of network delay, but can t handle IPv6 9
20 Summary Measurement in IPv6 is needed with the spread of IPv6 Principal benchmark systems are not support IPv6 We developed a new benchmark ANMA can specify request ratio of IPv6 and IPv4 We confirmed our benchmark Requests are sent at specified ratio IPv6 has some overheads compared with IPv4 20
