Scalable, Reliable & RedundantMirrored System WorkflowScalable, Reliable & RedundantMirrored System Workflow

1. Active server receives client requests

2. Mirrored server acts as hot standby receiving hot data

3. If active server fails, mirrored server takes status as active server using standard Linux failover

4. Active Server

Mirrored Architecture


Scalable, Reliable & RedundantClustered SystemScalable, Reliable & RedundantClustered System

• High available components throughout

– LivingRoom application servers clustered in n+1 architecture

– n+1 database servers– Highly available database storage– Highly available L4 switch

configuration

• Scalability & Reliability Workflow1. Clustered servers receive requests

from client (through L4 switch)2. L4 switch routes to server in cluster3. Servers all accessing highly available

DB4. Additional servers added for scalability5. Centralized database6. LivingRoom server fails, L4 switch

removes from cluster7. Requests routed through other servers

Benefits– Technology is “tried and true”– Scaleable – supports a very large

number of subscribers– Servers can also be maintained without

impacting entire IPTV service– Uses cost effective off-the-shelf

components

Reliability & Quality of ServiceKasenna Cluster ManagerReliability & Quality of ServiceKasenna Cluster Manager

1. Multiple servers clustered together to act as server system

2. Storage configuration includes content group + cache group

3. Content is distributed across servers

4. Playouts are spread across servers

5. If usage on track to exceed capacity of a server, content is automatically replicated to another server.

6. Cache is reclaimed once usage drops.

7. Load will be balanced across the server using standard protocols.

• Tiered or distributed networks are necessary if it is not practical to serve all users from one central point due to:– Bandwidth limitations – Speed of light limitations

– Scalability needs – Redundancy needs

• Typical tiers– Tier-1 (Super headend)

• Central Site – main ingest, library & distribution point

– Tier-2 (Regional headend) • Regional content, redundant feeds, distribution/propagation point

– Tier-3 (Edge site/POP, etc.)• Caching & streaming for popular content, reduced core bandwidth usage
