What is TCP multiplexing in load balancer?
The TCP multiplexing option enables Layer 7 load balancing virtual servers to “reuse” existing TCP connections between FortiADC and backend real servers. Using this connection pool can reduce TCP overhead and improve web server and application performance.
How do I monitor traffic on NetScaler?
Here is how you do that:
- SSH into the Netscaler using Putty.
- Type: sh lb vserver lb_vsvr_name. You will immediately see a lot of stats on how this VIP is configured like it’s IP, it’s status, connection method, persistency, bound service groups, etc.
- Now type: sh servicegroup svcgrp_name.
- Type:
What is TCP in Citrix?
TCP configurations for a Citrix ADC appliance can be specified in an entity called a TCP profile, which is a collection of TCP settings. The TCP profile can then be associated with services or virtual servers that want to use these TCP configurations.
Is NetScaler and ADC the same?
Citrix NetScaler Rebranded It is the defunct name for a line of networking solutions from Citrix. The NetScaler brand was changed in 2018, just a few days after Citrix’s annual Synergy conference. It consisted of the following products: NetScaler ADC: An application delivery controller is now called Citrix ADC.
How does TCP multiplexing work?
TCP provides multiplexing facilities by using source and destination port numbers. These port numbers allow TCP to set up a number of virtual connections over a physical connnection and multiplex the data stream through that connection.
How does TCP multiplexes conversations on to the same network?
How long does a TCP session last?
TCP connections will generally last about two hours without any traffic. Either end can send keep-alive packets, which are, I think, just an ACK on the last received packet. This can usually be set per socket or by default on every TCP connection.
What is connection multiplexing in NetScaler?
If the same client sends another request and this server side connection is not in the reuse pool, the NetScaler appliance opens a new connection to the same or some other server on the backend. The connection multiplexing takes place only on the HTTP virtual IP address and not on the TCP virtual IP address.
How does Citrix NetScaler TCP connection management work?
This article contains information about Citrix NetScaler TCP connection management. The client first opens a TCP connection to the NetScaler appliance, after which it sends the first HTTP request, the appliance creates a TCP connection with the backend server.
What is TCP connection multiplexing?
Connection multiplexing is a method of reusing the connections and avoiding the overhead of establishing the TCP connections for the data transfer after the connection established is no longer in use. Connection multiplexing has a positive impact on the performance of the server as well as the client-side, as explained in the following sections.
How does the NetScaler appliance work?
Then the NetScaler appliance forwards the request to the existing TCP connection to the target server. The request from the clients are sequentially forwarded through a small number of persistent connections to the server. You can use two modes of connectivity to accomplish connection multiplexing, Connection Proxy or Gateway.
