Sandvine made yesterday its MWC announcement - ".. the Policy Traffic Switch 22000 (PTS 22000) platform .. This latest generation of Policy Traffic Switch is ideal for service edge and aggregation layer deployments, including LTE networks, with up to 20 Gbps performance in a cost-effective two-rack-unit (2RU) form factor. Sandvine's innovative virtual switch cluster capability enables deploy-as-you-grow network build-out"
See "Sandvine to Unveil New LTE-Ready Policy Traffic Switch Platform at Mobile World Congress" - here. It is interesting to compare this to Allot's MWC/LTE announcement made last week (see - "Allot Boosts the Service Gateway to LTE - 160Gbps Throughput" - here). While Allot's focus was higher performance, Sandvine CTO, Don Bowman (picture), says "Whether the provider is operating in an emerging market where sustainable growth is the primary issue, or fighting in a competitive landscape where rapid innovation is the key to success, the PTS 22000 platform meets operators' flexibility and scalability requirements".
Sandvine also published very detailed information on the performance of its new device (see chart) and says that the product supports mobile data intersection for 3GPP Gn, Gi, Gp, IuPS, S5, S8, S1 interfaces (see chart for illustration of the LTE interfaces).

Thanks Azi, good catch.
ReplyDeleteSo it looks like Sandvine equipment has more deployment flexibilities than devices without those interfaces visibilities. What are the use cases for the deployment flexibility enabled by this?
The synchronous Ethernet implies the ability to deploy in the Iu (radio network) of 3G.
ReplyDeleteGenerally speaking the S1-U implies a lot more boxes with more visibility (since its closer to the radio).
This appears to be sized (price, performance) as ideal for deployment deep into an LTE network.
The ability to deploy near the edge of mobile networks provides several benefits for service providers including:
ReplyDelete- Increased access to control and data plane information available 'on the wire' in lower network segments streamlining the ease of integrating the solution significantly and enabling access to superior subscriber, device, location and application awareness.
- Dramatic reduction on the signaling message rate amongst the different systems involved in providing fine grained network policy control particularly for charging related use cases. The solution makes the implementation of such use cases viable through a balanced strategy in terms of time to market, standards compliance (3GPP/PCC/LTE) and Total Cost of ownership.
- Support to all network deployment sizes from small 20Gbps POPs to large 480Gbps installations at different port densities (multiple 1GE and 10GE interfaces). Through Sandvine carrier grade clustering technology, service providers can add capacity to the network according to the specific requirements of each POP.
I salute to the admin of this diary. i actually like and that i can sure as shooting advocate this diary to my friends.
