Cloud Enabling Platform: Load Balancing

• Load balancing criteria can be subscribers, application types,

application characteristics (delay or loss sensitive etc.) and so on that eventually determine the application server load

22

Cloud Enabling Platform: Congestion Control

• Local Congestion Control

–

Enforce traffic shaping on misbehaved subscribers / applications

–

Route traffic to least congested paths

• Global Congestion Control

–

Share local bandwidth and congestion information with all TPM peers

–

Enforce traffic shaping on misbehaved subscribers / applications at upstream

Load Balancer: Cloud vSBC Enabler

Key Notes

• Wrap all member SBCs as a single virtual SBC (vSBC)
• Support both Geo-centralized/distributed Load Balancing
• Guarantee Session Handling Continuity and Coherency
• Support Multiple Realms / Overlapping IP Address Spaces as a real SBC

26

Load Balancer: A Very Generic View

Key Notes

• Member SBCs can be in different network segments

–

meaning that they can be in different address spaces

–

allows load balancing amongst geo and network distributed SBCs

27

Load Balancer: As an L2 Transparent Element

Key Notes

• To the Access Node (IPa): SBC Load Balancer represents all member SBCs

–

exposes all member SBC addresses (IP1, IP2, IPn) to the access node as the destinations

• To the Member SBCs (IP1, IP2, IPn): SBC Load Balancer represents the access node

–

exposes the access node address (IPa) as the initiating source address

• Incoming traffic targeting a member SBC (e.g. IP1) may be served by a different

SBC (e.g. SBC2)

28

Load Balancer: As an L3 Proxy

Key Notes

• To the Access Node (IPa): SBC Load Balancer proxies all member SBCs

–

Hides all member SBC addresses (IP1, IP2, IPn) and proxies them using a proxy address (IPs) to the access node as the destinations

• To the Member SBCs (IP1, IP2, IPn): SBC Load Balancer represents the

access node

–

exposes the access node address (IPa) as the initiating source address
