Provide the network turning on service for the local area network main engine and the remote subscriber the router.
CEF Cisco express repeater
On the Cisco route's one kind of exchange pattern, it uses a repeater database FIB retrieval table, this table contains all existences in the routing list known route.
(data) compresses
Reduces with some algorithm processing data set stores up the space which this data set needs or transmits the band width which this data set needs.
Core level router
On network branch by quickest speed exchange data packet router.
May have custom-made the formation
Through gives each kind of protocol distribution formation space to guarantee the data stream band width one formation way.
The DDR on demand pulls out the number route
When the transmission data stream's terminal stand needs, the router can dynamic initiate with the closure circuit switching conversation connection one kind of technology.
Market days level router
Through will establish the route and the security policy will turn on the router which the level and the core level will differentiate.
And so on expenses load uniform graduated arms
Shares the data stream load in many same expenses or on the measure value link.
Stands fast trades
On the Cisco router's one kind of exchange pattern, it will use the high speed route buffer from now on the initial routing list retrieval.
FIFO advanced leaves the formation first
Is going to transmit the data packet carries on sorting according to the order which they arrive one kind of simple formation strategy.
Entire interconnection
Each router maintains mutually the direct connection the network
The increase route renews
One route update mode, the route renewed contains with already changed the route related information.
(data) package of exchange
On the router, receives the data packet on a connection, then it the process which retransmits from another connection.
Strategy
Processes certain types the data stream, renews, the route induction, the VLAN data stream and the address polymerization one method including the route.
Priority formation
The data frame acts according to the connection Output queue its each kind of characteristic, for instance the data packet size and the agreement type, differentiate the superior insignia one kind of formation strategy.
Advancement exchange
Involves to issues router CPU the entire data packet the advancement, in there, the data diaper packs take issues the output interface, the router makes the routing as each data packet. The advancement exchange is the CPU execution most resources intensity exchange operation.
Formation
The router uses in the jam time to process the data packet transmission scheduling problem the advancement.
