Accommodating voice and video in campus networks dating carib directory

For the deployment of Vo IP, a network infrastructure should support key Po E and Qo S features.

This ensures high-quality Vo IP service with low jitter and latency.

Today’s Vo IP solutions also require enhanced security and storage features to comply with CALEA (Communications assistance for law Enforcement Act)requirements, to enforce phone policies, and to collect Vo IP streams for billing and accounting.

This Paper concentrates on the architecture and requirements for campus enterprise customers.

Voice has traditionally been carried on circuit switched networks with resources dedicated for each call.

An example of emerging value-added services is Hosted Vo IP, which provides voice service with full PBX-like functionality with no onsite hardware requirements.

The In-Stat market research firm projects strong growth for Hosted Vo IP over the next few years, driven mainly by cost savings as well as additional benefits for companies with a distributed workforce.Brocade’s Fast Iron Po E switches such as ICX/FSX/FCX provide enhanced Vo IP, Qo S and security features required for a successful Vo IP deployment.The technological innovations in IP telephony and wide availability of cost-effective IP infrastructure networks have given rise to new business models.Campus Distribution The distribution layers (Also known as the aggregation layer), aggregates multiple access layer switches and connects them to the campus core.This layer deals with complex security, Access Control List (ACL), scalability, Qo S, STP, and MCT and so on.Collaboration services, such as voice and video conferencing equipment and video surveillance cameras, are also connected at this layer.
