WAAS & Akamai Cache Integration Model


WAAS and Cache Engine Integration

CE


WAAS and Cache Engine Integration


CE Process Model

• CE uses an asynchronous thread execution model that relies on WAAS for thread creation, management, and dynamic resource allocation and access.

• CE Processes:

• appme - configuration and management

• gatekpd –AMG communication,

• authentication, and configurationtraffic_server –cache processing

• apprep –reporting

• applog –logging component

Single-sided Optimization Dual-sided Optimization


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


• TCP address headers don’t change

• Connection headers can change

• Mode Settings (Conservative (default),

Standard, Aggressive, No-cache)

Transparent Object Caching (OC)


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

SC Architecture – Data Plane

Ingress Flows are checked against flow table. Active flows are passed to owner SN .

New flows are assigned an SN based on dynamic policy information and recorded in flow table.

Flows not requiring processing by an SN are passed through directly saving load on the SN

SC learns and syncs flow table with other SC(s).

To servers

SC-1 SC-2

SN-1 SN-2

• 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.



To servers

SC-1 SC-2

SN-1 SN-2

• 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.

3-tuple of source IP, destination IP, and destination port.

– Policy maps: Define actions for classified flows: Specify a primary SNG.

Specify a backup SNG.

Monitor the load of associated SN.

Specify a nested policy map

1. On the Cache Settings page change

the options you desire:

Select a transparent caching mode, turn the CC

or OTT on/off, and/or define host rules

If enabling the CC then Akamai API client

credentials check is done

2. Click on the Submit button to apply your cache

Site Specific Caching Policy Rules

CE turns on with transparent caching in Standard mode enabled as default

Over-the-Top caching is site specific; only YouTube.com is supported today

To enable transparent caching fora single site only:

Change Default Cache Policy to Bypass; then create a hostname rule with the caching type you want

Enabling Connected Cache will enable itfor all suitable Akamaized content


Cache Statistics

Hits

Bar graph is absolute cache hit count for the

specified interval

Line graph represents % of total objects

requested that resulted in a cache hit for the

Bandwidth Savings

Bar graph is absolute byte count for data served

out of cache for the specified interval

Line graph represents % of total bytes requested

Throughput Summary

The Throughput Summary displays throughput of

the Web traffic on the WAAS device

There is a link to toggle between LAN to WAN

(upload) direction, and WAN to LAN (download)

direction

Each chart shows the original throughput (actual

throughput observed by the endpoints – LAN

side), as contrasted to the optimized throughput

(after Akamai Connect optimization –WAN side)
