Why TRILL won't work for data center network architecture
There has been lots of hype around using the Transparent Interconnection of Lots of Links (TRILL) protocol for bridging and multi-pathing in data center networks, but a data center architecture with TRILL as the foundation ignores important emerging trends, including the need for varying types of virtual LANs (VLANs) for segmentation in cloud networks.
VLANs in data center network architecture
Virtual LANs (VLANs) have many applications and benefits but are most commonly used in the enterprise data center as a segmentation mechanism. They can be used to segment tiers of a single application or different applications and business units to provide failure isolation. They can enable administrative separation, secure the infrastructure and also comply with regulations. Today VLANs are also being adopted in the cloud to separate users. It is becoming increasingly clear that over the next decade, any architecture used for private and public clouds will need to allow for seamless and controlled communication within and across VLANs.
Because of their importance in the data center, it’s a good idea to look at the key scale properties of VLANs. Here are a VLAN’s three orthogonal scaling properties:
1. Size of a VLAN : This relates to the number of VLAN members. A large VLAN is useful to build a Layer 2 cluster for single applications, such as HPC or search, where the application is owned by a single entity (single-tier trusted application).
2. Number of VLANs : Standard Ethernet provides for 4K VLANs. If VLANs are also used to separate individuals, the number of VLANs required will far exceed 4K.
3. Stretch of a VLAN : This governs the locality (or lack) of the logical interfaces that are part of a VLAN. With virtualization, when an application has been separated from a physical device, it can be instantiated anywhere. However, the application still needs to retain its IP address and the associated policies (VLANs are an effective container for specifying policies).

The DHCP service in Windows Server 2003 allows you to assign multicast addresses Class D (IP address range: 224.0.0.0 to 239.255.255.255).
The addresses of this type are used by applications like video conferencing. Indeed,
the aim is to disseminate information to different customers while sending a single message.
The data flow operate in point to multipoint data streams as opposed to unicast which operates point to point.
Customers using multicast addresses must be configured to use the API MADCAP (Multicast Address Dynamic Client Allocation Protocol).
The API is usually used by MADCAP applications that work with multicast.
Also clients of multicast applications can be either be configured as DHCP clients for the unicast address.
In the DHCP console, right click on the name of your server and click New Scope Multicast . Enter a name and description after clicking Next . Click again on Next , then enter the IP address range for the multicast, then click Next . Now set the addresses to exclude from the beach, and then click Next . Then specify the duration of the lease and continue by clicking Next . To the question: ” Do you want to activate this scope multicast now? “, answer Yes and click Next , then Finish .
Notes : In the multicast range of private addresses defined in RFC 2365 and corresponds to addresses 239.192.0.0/14.
