39 WAAS & Akamai Cache Integration Model

40 WAAS and Cache Engine Integration CE

41 WAAS and Cache Engine Integration

42 CE Process Model CE uses an asynchronous thread execution model that relies on WAAS for thread creation, management, and dynamic resource allocation and access. n threads per core m threads per disk ~10 threads CE Processes: appme - configuration and management gatekpd AMG communication, authentication, and configuration traffic_server cache processing Asynchronous event processor Asynchronous event processor... Asynchronous event processor Disk I/O thread Disk I/O thread... Disk I/O thread Shared Resources Accept threads (per port) Logging threads Various "admin" threads apprep reporting RAM cache Disk cache Reloadable Configs Stats, logs etc. applog logging component

43 Data Path Single-sided Optimization Dual-sided Optimization

44 Cache-Control HTTP Response Header Refresher max-age: number of seconds (Time-To-Live, TTL) that an object is considered to be fresh must-revalidate: indicates the freshness directive must be obeyed and stale object cannot be served from an intermediate source no-cache: that the object must be returned directly from the origin server to the client and cannot be cached by an intermediary no-store: that the object cannot be stored in a cache at any time private: directs that the content can only be stored by the cache associated with the client that makes the request, typically the browser s cache proxy-revalidate: is identical to the must-revalidate header, but applied to proxy caches public: indicates that this is an authenticated response and that it can be cached s-maxage: the number of seconds that shared content used by proxies can be considered to be fresh

45 Transparent Object Caching (OC) TCP address headers don t change Connection headers can change Mode Settings (Conservative (default), Standard, Aggressive, No-cache)

46 Transparent, Connected & Dynamic URL Object Caching Cache & deliver content in-branch Intranet Web apps/content Akamai Platform Web apps/content Generic Internet apps/content Four caching policies supported Basic only caches objects marked explicitly as cacheable Standard also caches objects with no explicit cache marker that include a last modified date Advanced caches objects more aggressively for longer & GZIPs text files e.g. JS, CSS, etc. Bypass turns off caching

67 SC Architecture A Comprehensive View

68 A Day In The Life Of A Flow To Branches SC receives a TCP SYN packet, called green flow, from one of the branches containing a WAAS device. The SE classifies green flow and a pending entry is made into the flow database selecting SN-1. SN1 SC-1 SC-2 To servers SN-1 SN-2

69 A Day In The Life Of A Flow To Branches SC receives a TCP SYN packet, called green flow, from one of the branches containing a WAAS device. SN1 The SE classifies green flow and a pending entry is made into the flow database selecting SN-1. The frame is encapsulated and is transmitted to SN-1. SN-1 processes the frame and returns an indication the green flow should continue to be intercepted. SC-1 SC-2 To servers SN-1 SN-2

70 A Day In The Life Of A Flow To Branches SC receives a TCP SYN packet, called green flow, from one of the branches containing a WAAS device. SN1 SC-1 SC-2 SN1 The SE classifies green flow and a pending entry is made into the flow database selecting SN-1. The frame is encapsulated and is transmitted to SN-1. SN-1 processes the frame and returns an indication the green flow should continue to be intercepted. The other SC(s) are updated with the flow information and the frame is transmitted to destination. To servers SN-1 SN-2

SN1 SC-1 SC-2 SN1 The SE classifies green flow and a pending entry is made into the flow database selecting SN-1. The frame is encapsulated and is transmitted to SN-1. SN-1 processes the frame and returns an indication the green flow should continue to be intercepted. The other SC(s) are updated with the flow information and the frame is transmitted to destination. A TCP SYN-ACK frame is returned from the destination device and in this example goes to SC-1. SC-1 checks database, finds flow and sends the response frame to SN-1. To servers SN-1 SN-2
