ОБЗОР ПРОДУКТА

JUNIPER MEDIA FLOW BACKGROUND

Origin: Technology acquired from Ankeena Networks – April 2010. Roughly three
years in development.
Ankeena Founders: - Rajan Raghavan – RealChip, Xambala
- Prabakar Sunderrajan – Exodus, Netscaler
Today: Ankeena integrated in Juniper as the ‘Content and Media Business Unit’
Juniper Media Flow:
 Delivers media and rich content at a massive scale with smooth viewing
experience (50,000 transactions per second, 40,000 sessions per server) –
differentiated Smooth Streaming and Multi-tiered Caching
 Purpose-built software appliance that runs on generic x86 servers and
variety of storage devices (SATA/SAS/SSD/NFS).
Strategic Rationale for the Acquisition:
 Web 2.0 content becoming larger and more rich, benefiting from acceleration
and network awareness
 Performance Density in software
 SPs are designing CDNs to solve their video traffic explosion problems –
improve economics and enhance experience of video delivery
 Complimentary technology, mission and architecture

THE EVOLVING CONTENT DISTRIBUTION MODEL
Service providers own the Content providers partner
subscribers with CDNs
Service providers
can take different
paths for converged
delivery
Service providers
 IPTV / VoD Service providers own the distribute VOD, IPTV
subscribers within their own networks
 Internet only

Regardless, end
game is the same
 Converged media Mixed IPTV, VOD and Internet
video content on a converged
distribution - any content, architecture
any device, one delivery

PARTNER VS. BUILD

Partner examples
 EdgeCast
 DT uses Edgecast on it’s nodes to expand the global reach for
CDN solutions (http://www.edgecast.com/solutions/wholesale-cdn/)

 Bitgravity (example TATA Comunications)
 (…)Tata Communications’ CDN service powered by BitGravity.
With more than 300 points of presence worldwide(…)

Build examples
 Level 3
The company operates one of the largest communications and Internet
backbones in the world. Level 3 is a Tier 1 network and the current owner
of AS1. (http://www.level3.com/index.cfm?pageID=129)

TRANSPARENT PROXY CACHING
Transparent Caching: intercepts HTTP requests and redirects them to Web cache
servers or cache clusters. Router-based transparent proxy caching uses policy-based
routing to direct requests to the appropriate cache(s). For example, requests from
certain clients can be associated with a particular cache.
Transparent caches are also the simplest way to use a cache internally on a network (at
peering-hand off points between an ISP and a larger network, for example), because
they don't require explicit coordination with other caches.

REVERSE PROXY CACHING
Reverse Proxy Caching: Reverse proxy cache, also known as Web Server Acceleration, is a
method of reducing the load on a busy web server by using a web cache between the server
and the internet.
A reverse proxy cache differs from standard and transparent caches, in that it reduces load on
the origin web server, rather than reducing upstream network bandwidth on the client side.

Reverse Proxy Caches offload client requests for static content from the web server,
preventing unforeseen traffic surges from overloading the origin server.
