1-4 T-Series Traffic Director Installation, Configuration and Administration Guide
Chapter 1 Introduction
Each T1000 provides from 2 Gbps to 100 Gbps of non-blocking throughput (depending on
hardware model). The end-to-end throughput of a T1000 deployment with T3100 will be
limited by the maximum capacity of a single application blade (ASM), which ranges from
400 Mbps when used to perform lossy media optimization, up to 1 Gbps if only lossless
media and web-only optimizations are applied.
The throughput measurement for a T3100 cluster includes calculations for both ingress and
egress traffic passing through the LIMs. In other words, data moving from the Internet to the
subscriber must enter and exit the T3100, traversing the T1000 twice. Therefore, if the
T3100 replaces a router handling 10Gbps of throughput, the T1000 should be sized to
handle 20Gbps of throughput.
A second sizing factor to consider is the number and type of data ports. The T3100 data
plane may employ port trunking to increase throughput; a two-port trunk configuration
doubles the required number of T1000 ports on the subscriber and Internet sides. Support
for the optional T2100 Content Accelerator (video cache) may also require additional ports.
See
“T1000 Hardware Specifications and Options” on page 1-6 for the available port
configurations.
Product Capabilities
The T1000 combines a rich feature set with industrial-strength reliability, making it an
optimal choice for mobile network load-balancing requirements.
Load Sensitive Traffic Distribution
An intelligent health check mechanism accurately determines when applications blades
(such as Unison OSNs) are reaching specified thresholds. This innovative mechanism
avoids the latency inherent in existing health check algorithms which predict server load or
CPU utilization. As a result, the T1000 ensures subscriber traffic is directed to the right
Unison OSN or T3100 application module, preventing packet loss and ensuring maximum
availability of Smart Capacity applications.
Note: This feature is available in ByteMobile T3100 Release 7.0 and higher.
Intelligent Overload Protection
The T1000 determines which application blades are at or beyond a specified load threshold.
It then limits traffic to these blades while maintaining active subscriber sessions on them.
This capability enables the T1000 to manage traffic spikes effectively.
Carrier-Grade Redundancy
The T1000 can be configured redundantly, with state synchronization between two units to
ensure that applications are always available. The platform is NEBS Level 3-compliant,
with redundant fans and AC or DC power supplies.
