What's New in Release 6.6 (available summer 2013)Key features for streaming traffic and for setting up dynamic VPN connections
The Brocade Vyatta 54xx vRouters pick up where the Vyatta Network OS left off, adding enhancements to Vyatta's routing technology that offer network architects new ways to design and optimize their networks. The 6.6 release includes:
Dynamic Multipoint Virtual Private Networks (DMVPN)
Dynamic Multipoint Virtual Private Networks (DMVPN) allows branch locations to communicate directly with each other over the public WAN or Internet, without requiring a permanent VPN connection between sites. DMVPN improves network performance while eliminating the need to configure multiple tunnel interfaces for each branch.
DMVPN uses the multipoint Generic Routing Encapsulation protocol (mGRE) with the Next Hop Resolution Protocol (NHRP), secured with IP Security (IPsec) to simplify complex network topologies, especially hub-and-spoke topologies, by allowing spokes to communicate directly without the need to manually configure secure tunnels.
- Lowers capital and operational expenses -- Reduces costs in integrating voice, video with VPN security
- Simplifies branch communications -- Enables direct branch-to-branch connectivity for business applications like voice
- Reduces deployment complexity -- Offers a zero-touch configuration, dramatically reducing the deployment complexity in VPNs
- Improves business resiliency -- Prevents disruption of business-critical applications and services by incorporating routing with standards-based IPsec technology
IP Multicast Routing allows one sender to efficiently send data to multiple recipients. In addition to basic multicast route management, the Brocade Vyatta vRouter support includes Protocol Independent Multicast (PIM) for IPv4 and IPv6, and Internet Group Management Protocol (IGMP) with Multicast Listener Discovery (MLD). PIM support includes PIM Sparse Mode (PIM-SM), PIM Dense Mode (PIM-DM) and PIM source-specific multicast (PIM-SSM).
IP multicast routing provides an efficient method for forwarding traffic to multiple hosts, because multicast-enabled routers transmit multicast traffic only to hosts that want to receive the traffic. Hosts must signal their interest in receiving multicast data and they must join a multicast group in order to receive the data. Multicast-enabled routers forward multicast traffic only to receivers interested in receiving the traffic. Multicast is used primarily for streaming voice and video and for financial applications.
