FR-1000 Internet Traffic ManagerTM (ITM)
The Saisei Networks Anagran FR-1000 is an advanced Internet traffic manager (ITM) that allows service providers of all types to reduce the cost of network capacity while improving throughput and reducing delay for all users. In addition to creating a more efficient, deterministic environment, the FR-1000 can be used to mitigate the bandwidth consumed by aggressive peer-to-peer file sharing applications, thereby minimizing their impact on other users. It can also be used to ensure that “quality sensitive” applications such as over-the-top (OTT) video, on-line gaming, and voice over IP (VoIP) receive sufficient bandwidth to deliver the quality that broadband subscribers expect.
The Saisei Networks Anagran FR-1000 product is easy to install, configure, manage and maintain, seamlessly integrating into any multi-vendor network infrastructure.
System Description
Saisei Networks Anagran FR-1000 is a one rack unit (RU) modular system with four slots per unit for Interface Modules (IMs).
Quality of Service (QoS) Features
The FR-1000 continuously monitors the rate of all TCP flows and dynamically adjusts their rates based on network policies. Flows can be treated as:
- Available Rate (AR) – for applications that work well over a wide range of network speeds, the FR-1000 will adjust the speed of AR flows to match the configured policies.
- Fixed Rate (FR) – for applications that require a minimum rate to operate correctly and are sensitive to packet loss, such as OTT video, on-line gaming, and VOIP.
Class Based Policies
The FR-1000 groups flows into classes based on:
- Flow Access Control Lists (FACLs).
- Behavioral rules based on packet size, bandwidth, duration.
- Hosts/subscribers/users including behavior based on total host bandwidth and number of active flows.
Policies are then applied based on class membership. Policy actions include:
- Fair bandwidth per flow.
- Fair bandwidth per host/subscriber/user – flow rates adjusted to utilize all bandwidth in the class.
- Capped bandwidth per flow or per host/subscriber/user.
- Proportional weighting of flows or hosts for tiered services, e.g. gold/silver/bronze hosts/subscribers/users.
- Assured rate guarantees that a class of flows of hosts/subscribers/users will get a minimum bandwidth.
- Redirection, DSCP remarking.
Classes can be grouped into hierarchies for more complex policies.
Summary
The Saisei Networks Anagran FR-1000 ITM is a critical network element designed to dramatically improve network efficiency and utilization, enable tiered subscriber/user services, and fundamentally improve the user’s network experience.
