Service aware switch engines tracks mobile and cloud access
According to IEEE, communications networks will need to support an average of 58% compound annual growth rates in bandwidth. Operators are moving quickly to packet-based networks to meet opex/capex goals as they try to address this traffic explosion and control network build-out costs. Operators that provide new revenue generating services over private or public cloud networks require new Carrier Ethernet features, including multi-operator OAM and Service Activation Testing to support maintenance and billing. Operators must also deliver these services in a ubiquitous, reliable and secure manner over these new 4G LTE and cloud-based networks.
"Serval-2 revolutionizes the way in which carriers can deliver services over Ethernet for high bandwidth mobile backhaul, video distribution, cloud access and more," said Uday Mudoi, product marketing director at Vitesse. "Vitesse Service Aware Architecture enables efficient delivery of these services. Serval-2 represents Vitesse’s continued focus on delivering solutions for a new generation of network access equipment for mobile/IP Edge and cloud."
Adding to the company’s widely adopted Serval-1™ and Serval-Lite™ switch engines, the Serval-2 family is MEF CE 2.0 ready with per connection feature control and resource allocation. Each Ethernet Virtual Connection (EVC) can utilize dedicated policers and shapers, statistics, queues, and tagging/marking schemes. Further, each connection may use built-in service activation testing when first provisioned; dedicated OAM functions ensure fault-free and SLA-compliant operation;
Serval-2 also delivers calable support of multiple 1 Gigabit Ethernet (GE) and 10 GE ports without the need for additional external components. Current solutions, which typically involve external FPGAs or NPUs to enable Carrier Ethernet features, suffer major performance hits when scaling to the higher bandwidth needs of today’s demanding consumers. In contrast, Serval-2 executes performance-critical functions including OAM and protection switching, and maintains wirespeed performance for even the most demanding service delivery functions;
Other features include VeriTime™ nanosecond-accurate IEEE1588v2 timing technology that meets LTE and LTE-Advanced network requirements, including those of variable-rate and asymmetric millimeter wave and microwave links; support of multi-operator OAM&P and Service Level Agreements for Ethernet management, enabling RAN sharing and third-party backhaul ownership; and hierarchical QoS (H-QoS) support for high bandwidth, media rich traffic delivery over 4G networks.
When combined with Vitesse Intellisec™-enabled PHYs, the Serval family enables a secure network for Layer 2 VPN services at a price point that is 50% lower than alternative solutions. Samples of Serval-2 will be available in calendar Q3 2013.
