Link Layer Discovery Protocol (LLDP)
LLDP is an open standards L2 protocol that allows your network devices to advertise their identities and capabilities on the local network. You can use
LLDP in many important ways, including to discover IP phone connections, and to generate network maps from network devices.
Policy-based Routing (PBR)
PBR provides multiple different cost paths to the same destination. Your network manager sets policies or rules that define which paths packets will
follow. PBR provides equal access, protocol-sensitive routing, and can control where different sets of traffic are forwarded in instances where network
amalgamation has resulted in overlapping address spaces.
IGMP Query Solicitation
Query Solicitation minimizes loss of multicast data after a network topology change. It is important in multicast networks when used in combination
with STP or EPSR to provide fast recovery of multicast traffic from network failures.
VCStack Resiliency Link
The VCStack Resiliency Link prevents unnecessary stack failures, and minimises network disruption.
Key Solution - Network Access Control (NAC)
One of the major security issues facing enterprise networks is how to prevent internal breaches and malicious software infiltration. Internal
defence requires significant involvement with individual network devices, which is costly and time consuming. NAC lowers this overhead and
provides an effective solution to internal network security.
NAC automates network security policy management, allowing you to easily control network access and manage network security. NAC uses
802.1x port-based authentication in partnership with standards-compliant dynamic VLAN assignment, to assess a user’s adherence to network
security policies and either grant authentication or offer remediation. Allied Telesis NAC also supports alternatives to 802.1x port-based
authentication, such as web authentication to enable guest access, and MAC authentication for end points that do not have an 802.1x supplicant.
This ‘Tri-Authentication’, shown in Diagram 1 below, provides a way for the network to successfully manage authentication of all devices.
Allied Telesis is also a partner with Microsoft, supporting Microsoft Network Access Protection (NAP) technology. Allied Telesis is committed
to providing secure networks, and interoperability with Microsoft's network access control solution is an important component of an already
comprehensive security set. The Allied Telesis NAC solution also interoperates with many other third party NAC solutions
