Netgear S3300-28X-PoE+ (GS728TXP) - ProSAFE S3300 Smart Switch Series 管理者ガイド

The Multiple Registration Protocol (MRP) feature is only supported on 
a standalone S3300 switch. Standalone here means that all four stack 
ports are running in Ethernet mode.

Multiple Registration Protocol (MRP) is a base registration protocol that enables devices 
running an MRP application to register attributes to other devices in a network. MRP provides 
an application to register attributes such as bandwidth requirement for a given AV stream and 
MAC address information. It is used by various applications to propagate the registration. The 
switch supports the following MRP applications:

Multiple MAC Reservation Protocol (MMRP)

Multiple Stream Reservation Protocol (MSRP)

Multiple VLAN Registration Protocol (MVRP)

MMRP allows for the propagation MAC address information in the network, and allows for the 
registration and deregistration of both individual MAC address information and group MAC 
address membership. End stations may request to join or leave a multicast group, or to 
register an individual MAC address with a specific VLAN. MAC address entries can be 
dynamically registered and deregistered if MMRP is administratively enabled on the switch.

MSRP reserves necessary resources in the network to facilitate time sensitive traffic to flow 
end to end. In a typical network, there are multiple Talkers (those who transmit streams) and 
multiple Listeners (those who receive streams from one or many Talkers). Each flow has 
specific bandwidth, frame rate, and time sync requirements. With the use of MSRP these 
resources are guaranteed through all intermediate devices that are between any talker and 
listener. 

MVRP registers VLANs in the network, enabling automatic VLAN configuration on the switch. 
In a typical network, VLAN tagging is common. Many nodes require ingress traffic to be 
tagged with specific VLAN ID, and other nodes require egress traffic to be transmitted with a 
specific VLAN ID. With the use of MVRP on both ingress and egress, no manual VLAN 
configuration is required to pass tagged traffic through the network.

MRP framework must be available and enabled in all intermediate 
devices to ensure that the propagation of the attributes occurs 
throughout the network.

With MRP, network attributes are declared, registered, withdrawn, and removed completely 
dynamically without any user intervention. This dynamic nature is especially useful in 
networks where:
