Zevenet API v3 Reference

ZAPI (Zevenet Application Programming Interface) is the tool for system administrator to controler Zevenet load balancer conduct.

It is necessary active the zapi user from the web interface before use it, System/Users.

Once the zapi user has been created, it is possible send request to the URL, https://zevenet_server:444/zapi/v3/zapi.cgi/URI_path.

zevenet_server is the IP where HTTP service is listening.

URI_path defines the object or action to act. Its behavior and its parameters will be defined within each one doctumentation section.

The verbs used in this API will be GET, POST, PUT or DELETE. A PUT or POST request always need almost a parameter although this doesn’t need any required parameter.

HTTP Farms

HTTP profile is an advanced layer 7 load balancing (or Application Delivery Controller) with proxy special properties. This profile offers some features like HTTPS layer 7 load balancing combinated with SSL offload acceleration. This profile is adecuated for web services (web application servers included) and all application protocols based on HTTP and HTTPS protocols like WebDav, RDP over HTTP, ICA over HTTP, etc. In order to configure this farm profile, a virtual IP address and a virtual TCP port will be required.

HTTP - Services

The services within a HTTP profile farm provides a content switching method to deliver several web services with different properties, backends or even persistence methods, through some deterministic conditions used by the farm core in order to match the correct service for every client request. This service definition will be used by the farm in order to determine the backends servers that could deliver the response to the client.

Inside service object there are two kinds of values: service related and farmguardian related.

Farmguardian is used for advanced monitoring state of backends and totally personalized for your own scripts for the current service. When a problem is detected by farmguardian automatically disables the real server and will be marked as blacklisted.

For a complete description of Service object in a HTTP farm refer to HTTP Farms > Retrieve farm by name > Table Services object for HTTP farms

L4xNAT Farms

The L4xNAT profile farm allows to create a L4 farm with a very high performance and much more concurrent connections than load balancer cores in layer 7 like HTTP farm profiles. That layer 4 performance improvement counteracts the advanced content handling that the layer 7 profiles could manage.

Additionally, L4xNAT farms could bind a range of ports, not only one virtual port as is used with other layer 7 profiles. In order to be able to select a range of virtual ports or a specific virtual port in L4xNAT farms, it’s mandatory to select a protocol type. In other case, the farm will be listening on all ports from the virtual IP ( indicated with a character ‘’ ). Once a TCP or UDP protocol is selected, it will be available to specify a port, several ports between ‘,’ , ports range between ‘:’ or all ports with ‘’. A combination of all of them will be valid as well.

GSLB - Services

A GSLB service represents a group of real servers and an associated algorithm to be used for them. In order to create a new service, you’ve to set a valid identification name and the desired algorithm to use.

The available services are:

Round Robin: equal sharing. An equal balance of traffic to all active real servers. For every incoming connection the balancer assigns the next round robin real server to deliver the request.

Priority: connections always to the most prio available. Balance all connections to the same highest priority server. If this server is down, the connections switch to the next highest server. With this algorithm you can build an Active-Pasive cluster service with several real servers.

GSLB - Zones - Resources

Resources defined as the DNS service resolves requests. The possible DNS resources in Zevenet load balances are:

  1. NS. Name Server type record, it delegates a DNS zone to use the given authoritative name servers.
  2. A. Address type record, it returns an IPv4 address of a host.
  3. CNAME. Canonical name type record, it represents an alias of a given name.
  4. DYNA. Dynamic address type record, it returns a dynamic address specified by a GSLB service already created within the farm configuration according to the algorithm selected for such service.
  5. AAAA. Address type record, it returns an IPv6 address of a host.
  6. MX. Mail exchange type record, maps a domain name to a list of message transfer agents for that domain.
  7. SRV. Service locator type record, Generalized service location record, used for newer protocols instead of creating protocol-specific records such as MX.
  8. TXT. Text type record, it is used to store any text-based information that can be grabbed when necessary. We most commonly see TXT records used to hold SPF data and verify domain ownership.
  9. PTR. Pointer record, pointer to a canonical name. Unlike a CNAME, DNS processing stops and just the name is returned. The most common use is for implementing reverse DNS lookups.
  10. NAPTR. Naming Authority Pointer, Allows regular-expression-based rewriting of domain names which can then be used as URIs, further domain names to lookups, etc.

Network

Zevenet can work with different types of network interfaces.

In this section you can list, create, configure, delete and set an action in NIC, VLAN, virtual and bonding interfaces.

nic: or network interface card, it is a computer hardware component and tis kind of interface is the base for the following kind of interfaces that can be defined and managed in Zevenet.

vlan: or virtual lan card is kind or network interface that provide network segmentation services. More than one vlan can be created through a nic interface. bonding: Also called by another vendors as trunk interfaces, this kind of nic can be created with more than one nic interface. Zevenet supports 7 different types of bonding interfaces.

virtual: This kind of interface can be created over any kind of interface describew above. This kind of interface should be used for Farms and it is required that the virtual interface is defined in the same subnet than the parent.

Network - Bonding interfaces

The Linux bonding interface or also called by another vendors as Trunk provides a method for aggregating multiple network interfaces into a single logical “bonded” interface. The behavior of the bonded interfaces depends upon the mode, Zevenet Load Balancer supports the following methods:

Round-robin policy: Transmit packets in sequential order from the first available slave through the last. This mode provides load balancing and fault tolerance.

Active-backup policy: Only one slave in the bond is active. A different slave becomes active if, and only if, the active slave fails. The bond’s MAC address is externally visible on only one port (network adapter) to avoid confusing the switch. This mode provides fault tolerance. The primary option affects the behavior of this mode.

XOR policy: Transmit based on source MAC address XOR’d with destination MAC address. This selects the same slave for each destination MAC address. This mode provides load balancing and fault tolerance.

Broadcast policy: Transmits everything on all slave interfaces. This mode provides fault tolerance.

IEEE 802.3ad LACP: Creates aggregation groups that share the same speed and duplex settings. Utilizes all slaves in the active aggregator according to the 802.3ad specification.

Pre-requisites:

  1. Network interface support in the base drivers for retrieving the speed and duplex of each slave.

  2. A switch that supports IEEE 802.3ad Dynamic link aggregation. Most switches will require some type of configuration to enable 802.3ad mode.

Adaptive transmit load balancing: Channel bonding that does not require any special switch support. The outgoing traffic is distributed according to the current load (computed relative to the speed) on each slave. Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed receiving slave.

Pre-requisite:

Base driver support for retrieving the speed of each slave.

Adaptive load balancing: Includes Adaptive transmit load balancing plus receive load balancing for IPV4 traffic, and does not require any special switch support. The receive load balancing is achieved by ARP negotiation. The bonding driver intercepts the ARP Replies sent by the local system on their way out and overwrites the source hardware address with the unique hardware address of one of the slaves in the bonding such that different peers use different hardware addresses for the server.

IPDS

This module is the implementation of a IPS (Intrusion Prevention System) and IDS (Intrusion Detection System) system for offering to the user a security layer. IPDS module inspects the traffic just before to reach the Load Balancing modules LSLB or GSLB, if the traffic is detected as malicious then it will be rejected.

It works applying security rules to the system which will be defined as object of different nature. Each one offers a solution for external malicious or suspicious action. This tool helps to the system administrators controlling threats and attacks.

The available rules to apply to Zevenet can be blacklists and DoS.

IPDS - Blacklists

Blacklists lets users to use lists to filter or allow traffic according to source IPs (Incomming traffic).

There are two types of lists:

  1. Remotes: Lists are obtained from a URL, those lists are not modificable and can be sheduled to be downloaded.
  2. Local: Users can create their own lists with a given policy, deny if the incomming IP matches then the traffic will be rejected or allow if the incomming IP matches then the traffic will be allowed.

This module includes preloaded lists provided by Zevenet team, the list are ready to be applied to farms. Aditionally, users can create their own personalized lists.

Several lists can be applied to the same farm, if the source IP matches in some of the list the traffic will be allowed or denied depending of the blacklist policy. At the moment the IP matches then no more black list checks are done to the source IP.

If a source IP is in two different lists deny and allow, then always the allow policy is evalluated first.

IPDS - DoS

DoS protection has different type of rules, depend of the protection rule, it is applied to a different part of balancer. So there are system rules that it applies all balancer. Connection oriented rules, specific for farm working with TCP protocol. Before applying a rule to a farm, create an object with the configuration wished. Next, applied it to all farms that you need it. The system rules have the object created already and only have one possible configuration. Once configurated, enable it.

System - Cluster

The cluster is the element done by a master node, that it manages the connections fordward the backends, and a backup node checking the master, it is prepared to swich to master node if it goes to down status.

When there is a status switched, the backup node will restore all connection status in itself. So, client does not detected an interruption in the service.

This let put the load balancer in high availability. So if there are any issue in a Zevenet, the service will continue working with the uploaded configuration.
