vBRAS — CP Solution
应用文章
With the booming development of the Internet, the Mobile Internet, and the related services (like Broadband-—a much faster and resilient transport network) have become the need of the hour. The traditional Broadband Remote Access Server or BRAS is facing some serious challenges such as uneven resource usage, long service provisioning cycle, and dispersed management to name a few. To overcome these disadvantages, an advanced version of BRAS is being proposed by network device vendors called virtualized BRAS or vBRAS. vBRAS with its decoupled control and user plane architecture not only mitigates the existing challenges faced by BRAS but also brings in more capabilities to make the carrier network faster and resilient.
Some of the capabilities are:
- Better service reliability
- Shorter service provisioning cycle
- Less amount of IP addresses (using Carrier Grade NAT, that is CNG)
- Centralized configuration management using NETCONF
- Much simplified OAM
