Mojo Multiservice Platform
Move to the Mojo cloud without impacting your underlying network

Overview

The Mojo Multiservice Platform extends client VLANs all the way to Mojo access points across routing domains using Layer-2 EoGRE tunnels. Enterprise deployments using the legacy controller architecture usually tunnel all client VLAN traffic from the access points to the controller because the client VLANs are not available on the wired ports of the access points. The Mojo Multiservice Platform allows Mojo access points to seamlessly integrate in such deployments.

A Mojo AP creates a tunnel between itself and the Mojo Multiservice Platform and ensures that the edge and core switches are transparent to the VLAN configurations. A tunnel supports multiple VLANs behind the AP. Defined tunnel interfaces can be combined using link aggregation to increase overall throughput. The Mojo Multiservice Platform transparently switches the traffic among tunnels and trunk ports, through dynamic learning and forwarding. Trunk port connectivity is on to the wired side of upstream, where traffic would flow transparently without a tunnel. Mojo Multiservice Platform has the intelligence to learn the EoGRE tunnel information originating from an AP and dynamically establishes the GRE tunnel with the AP. The AP injects Ethernet traffic of multiple VLANs into the same tunnel and the Ethernet frames carry VLAN tag (802.1q) and aggregator then switches packets to the correct VLAN (downstream to other tunnels and to the upstream switch).

Mojo Multiservice Platform includes Dynamic Host Configuration Protocol (DHCP) server designed to automatically assign IP addresses based upon a configured range. Mojo Multiservice Platform has several traffic optimizations like broadcast/ multicast control to prevent unnecessary flooding of packets across the network and IGMP snooping to allow IGMP only when there is a client which needs that multicast stream. The Mojo Multiservice Platform is QoS aware. For manageability of the platform, configurations can be easily saved and restored in addition to a High Availability (HA) mode of deployment.

High-Level Architecture
Mojo Multiservice Platform creates an alternative data plane. Data can be locally branched out or it can be tunneled to the traffic aggregator. The choice depends on the deployment use case

Communication Topologies Supported
Communication is possible between wireless clients belonging to the same VLAN, wired and wireless clients on the same VLAN or clients belonging to different VLANs.

Intra-VLAN
A sample configuration and traffic flow within the same VLAN between two wireless clients and that between a wireless client and wired client using the Mojo Multiservice Platform is shown in the figure. The Mojo Multiservice Platform bridges traffic belonging to the same VLAN.

Inter-VLAN
A sample configuration and traffic flow between wireless clients on different VLANs using the Mojo Multiservice Platform, a distributed switch and an enterprise router is shown in the figure. An upstream Layer 3 device routes the inter-VLAN traffic across VLANs.
