TCP Profile WAN Optimized
Problem this snippet solves: This is a custom TCP profile which optimizes TCP traffic for a Wide Area Network environment by tuning the TCP stack. Enabling selective ACKs produces faster recovery from transmission errors. Nagle's Algorithm reduces the number of short segments on the network. (Enabling this setting for interactive protocols such as telnet may cause degradation on high-latency networks.) The buffer and window sizes are increased to maximize throughput for high-latency conditions. (This profile is included as a standard profile in LTM 9.4.) Code : profile tcp tcp-wan-optimized { defaults from tcp selective acks enable nagle enable proxy buffer low 131072 proxy buffer high 131072 send buffer 65535 recv window 65535 }TCP Profile LAN Optimized
Problem this snippet solves: This is a custom TCP profile which optimizes TCP traffic for a Local Area Network environment by tuning the TCP stack. Disabling bandwidth delay prevents LTM from attempting to calculate the optimal bandwidth to use to the client, based on throughput and round-trip time, without exceeding the available bandwidth. Nagle's Algorithm is useful for reducing the number of short segments on the network. (Neither is necessary for low-latency LAN traffic, and can introduce latency and overhead due to the required calculations.) The buffer and window sizes are optimized to maximize throughput/minimize latency. (This profile is included as a standard profile in LTM 9.4.) Code : profile tcp tcp-lan-optimized { bandwidth delay disable nagle disable slow start disable ack on push enable proxy buffer low 98304 proxy buffer high 131072 send buffer 65535 recv window 65535 }HTTP Profile WAN Optimized Compression Caching
Problem this snippet solves: This is a custom HTTP profile which optimizes HTTP traffic for a Wide Area Network environment with KeepAlives, Caching and Compression). It enables a 50Mb cache that operates on files < 2Mb in size, caching them for up to 24 hours. It enables compression buffer with settings to enable fast compression of all data, and inclusion of some data that typically would not be compressed. With OneConnect transformations enabled, LTM transforms "Connection: Close" headers in client-side requests to "X-Cnection: Close" headers on the server side, allowing the BIG-IP LTM to make eligible for connection reuse any client requests containing the "Connection: Close" header (i.e. HTTP/1.0 requests). (This profile is included as a standard profile in LTM 9.4.) Code : profile http http-wan-optimized-compression-caching { defaults from http oneconnect transformations enable compress enable compress buffer size 131072 compress vary header enable compress http 1.0 enable compress gzip memory level 16k compress gzip window size 64k compress gzip level 1 response unchunk ramcache enable ramcache size 50mb ramcache max age 86400 ramcache min object size 0 ramcache max object size 2000000 }HTTP Profile WAN Optimized Compression
