The Impact of Virtualization on Application Delivery Over the WAN

Although virtualization has received a lot of attention in the trade publications over the last couple of years, it is not a new concept. IT organizations have been implementing virtualized technologies such as Virtual LANs VLANs and Virtual Private Networks VPNs for at least twenty years. Most of the recent...

Securing Physical and Virtual IT Assets Without Hardware Firewalls or VLANs - A New Approach: An Identity-Aware Network Inside the Perimeter

For security administrators at large corporations, the growing management complexity of internal firewalls and Virtual LANs VLANs presents significant security challenges. The growing reliance on Virtual Machines VMs also introduces significant security vulnerabilities. Communication between VMs is fully undetected by traditional hardware firewalls. In addition, when VMs move, they usually...

Session Initiated Protocol (SIP) and Message-Based Load Balancing (MBLB)

At the service provider level, the number of VLAN, TCP or UDP port, and IP triplet combinations is affecting the Session Initiated Protocol SIP. Between servers, where the VLAN, TCP port, and IP variations are limited, the ephemeral ports are constantly being pushed and overrun. Because of active SIP subscriber...

Globally Distributed Ethernet Switching

With IT staffs laying out plans for implementing virtual servers, massive storage arrays, and disaster recovery sites, it is extremely important and useful to link these sites to a truly reliable, active-active multiple redundant, high-speed Layer 2 Ethernet network. In addition, a truly "Distributed switching" system that can act and...

Inference of Network-Wide VLAN Usage in Small Enterprise Networks

Virtual Local Area Networks VLANs are heavily utilized in enterprise networks to group hosts with common requirements together as if they were on the same LAN although they may be in separate physical locations. The key benefit of VLANs is its flexibility to allow any logical LAN to be implemented...

Network Warrior: VLANs

Virtual LANs, or VLANs, are virtual separations within a switch that provide distinct logical LANs that each behaves as if they were configured on a separate physical switch. Before the introduction of VLANs, one switch could serve only one LAN. VLANs enabled a single switch to serve multiple LANs. Assuming...

Scalable Ethernet Using VLAN Stacking

Thanks to the recent standardisation of long-range, high-bandwidth Ethernet interfaces, Ethernet can now be used in metropolitan networks. It can be said that Ethernet now offers the same bandwidth and range as traditional WAN technologies. However, adapted interfaces alone do not turn Ethernet into a WAN technology. A carrier-class network...

A VLAN Ethernet Backplane for Distributed Network Systems

In a network system, such as a router or a switch, it is difficult to achieve flexibility and performance at the same time. This paper proposes an architecture that consists of network processors for packet processing and a VLAN-based Ethernet backplane for switching. This allows to use flexible network processors...

Understanding and Configuring VLAN Trunk Protocol (VTP)

VLAN Trunk Protocol VTP reduces administration in a switched network. When a user configures a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. VTP is a Cisco-proprietary protocol that is available on...
