Vitesse’s access switch chip enhances Ethernet service support

Vitesse Semiconductor has detailed its latest Carrier Ethernet access switch for mobile backhaul, cloud and enterprise services.

 

The Serval-2 chip boosts Vitesse’s existing access switch offerings by adding 10 Gigabit Ethernet (GbE) ports and near-tripling the switching capacity to 32Gbps; the Serval-2 has 2x10GbE and 12x1GbE ports.

The device features Vitesse’s service aware architecture (ViSAA) that supports Carrier Ethernet 2.0 (CE 2.0). “We have built a hardware layer into the Ethernet itself which understands and can provision services,” said Uday Mudoi, product marketing director at Vitesse.

CE 2.0, developed by the Metro Ethernet Forum, is designed to meet new service requirements. The first equipment supporting the technology was certified in January 2013.

What CE 2.0 does not do is describe how services are implemented, explains Mudoi. Such implementations are the work of the ITU, IETF and IEEE standard bodies with protocols such as MPLS and Q-in-Q. “There is a full set of CE networking protocols which comes on top of CE 2.0,” said Mudoi.

Such protocols, and certain non-standard features, are supported by ViSAA. One example non-standard feature is how the Ethernet access device separates the network link to the service provider from the customer one. “You have, within the switch, to isolate those two domains,” said Mudoi.

Other features supported by ViSAA include multi-operator operations, administration and maintenance (OAM), hierarchical quality of serice (QoS) and service activation testing. “Before you provision a service, you need to run a test to make sure that once your service is provisioned, [and] the user gets the required service level agreement,” said Mudoi. Serval-2 supports the latest ITU-T Y.1564 service activation standard.

First samples of Serval-2 will be available in the third quarter of 2013. Vitesse expects it will be a further six months for system qualification; Ethernet access devices carrying live traffic can be expected from the first half of 2014.
