ROHITA is an experienced project management and network design consultancy using PRINCE2 methodology. We have a strong track record of successfully delivering complex and difficult technical projects. Our strengths include clear thinking, strong customer focus, excellent communication, good documentation, the ability to simplify and a consultative approach.
MPLS Core for Managed Service Provider
We developed and implemented a strategic network architecture to enable our customer to streamline their Managed Services delivery. The architecture is MPLS VPN’s overlaid on a standard Cisco 3-Tier Campus design. This provides scalability and standardisation in order to accelerate our customer’s take-on of new Managed Services clients, and gives our customer the flexibility to provide value-added services such as monitoring and backup to their clients wherever they are within the data centre estates. Virtual firewalling allows our customer to centralise and simplify firewall deployment, and to move away from managing individual dedicated firewalls per customer. Technologies included: Cisco Cat6500’s, MPLS, FWSM, OSPF, BGP, Optical Fibre
Firewall Consolidation
The goal of this project was to simplify our customer’s network by eliminating as many dedicated firewalls as possible. These had been literally strewn around the network, and each contained anomalous rule bases and quirks. The solution was to implement centralised, virtual firewalling using the Cisco Firewall Services Module, and then eliminate the dedicated physical firewalls by porting their rule base onto virtual firewalls on the central blades. The result was to radically simplify the network making it much easier to support, and reduce the cost of firewall maintenance.
ISP Network for 4,000 schools
Our customer was the ISP for 4,000 schools in the East of England. Which had bought managed WAN, LAN, firewalling and hosting services from an upstream ISP based on a high level design. Retained by the upstream ISP as the solutions consultancy, ROHITA was responsible for producing a detailed technical design and for managing every phase of the implementation and migration until the network was fully operational and handed over to support. A key challenge was establishing cordial relationships with the rival ISP that had lost the contract, in order to ensure a seamless transfer of services. Technologies included: Cisco Cat3750’s, 7301’s, GRE, OSPF, EIGRP, BGP, Checkpoint, BT Megastream Ethernet
Global MPLS WAN:
An MPLS Service Provider had sold a global MPLS WAN to a US corporation with sites in the UK, US, and throughout Europe. ROHITA was retained to create the detailed network design, manage a team of engineers, and oversee the complete implementation of the new WAN. Because the MPLS WAN was replacing two existing Frame Relay networks a key challenge was to devise a suitable migration plan that maintained consistent routing and ensured no loss of service during the migration. Technologies included: MPLS, Frame Relay, Cisco ISR routers, QOS, HSRP, BGP, EIGRP, RIPv2.
Campus LAN for Hospital Trust
Our client was one of the largest hospital trusts in the UK comprising 3 city hospitals. ROHITA was contracted to design a new multi-campus Cisco MAN. One of the key challenges was integrating the new network with BT N3. We liaised closely with BT N3 to ensure a MAN design which would fulfil the Trust’s requirements and would also be compliant with NpfIT. It was essential that the MAN should be able to handle sensitive and bandwidth intensive applications such as IP Telephony and medical imaging, and security was a key consideration at all times. We were heavily involved in the Trust’s ambitious plans for pervasive wireless networking throughout their estate, capable of supporting next-generation applications such as RFID for asset tracking and IPT. Technologies included: Cisco Cat6500’s, QoS, Cisco wireless.
National MPLS WAN
Our role was to design an MPLS WAN to connect a commercial estate agency with 10 UK sites to our customer’s data centres, as part of a Managed Services transition. Key aspects of the solution included the ability to route multiple virtual networks (VRF’s) across the circuits into the data centres, in order to accelerate the future take-on of additional customers. Other aspects of the solution including routing manipulation to enable simultaneous use of both primary and secondary access circuits at the customer sites. Centralised firewalling and resilient Internet provision was also built into the solution. Technologies included: MPLS, FWSM, QOS, HSRP.
Metropolitan Area Network
Formed from the merger of two universities, this London Metropolitan University is the third largest in the UK with 35,000 students. I provided them with a strategic design to: a) integrate and unify their two separate networks by building a MAN across the city; b) improve availability and performance utilising two purpose-built data centres; and c) enable the adoption of new technologies such as IPT, wireless and e-learning. Technologies included: Cisco Cat6500’s, CWDM, optical fibre, GSS.
Insurance
Our client was a FTSE 100 company specialising in insurance and pensions. Rohita Ltd. was responsible for managing LAN upgrades in a number of the company’s offices around the country, liaising closely with IT and business executives to ensure minimal disruption, and co-ordinating with 3rd parties such as telecoms suppliers.
Pensions Company
Our client was a pensions company based in London. Our role was to co-ordinate a LAN upgrade with an office reorganisation. A key challenge was to minimise risk and to ensure business continuity on a per-departmental basis throughout the project lifecycle.
Firewall Upgrade Project
Our client was a software and services company with offices in the UK and the USA. Our role was to project manage the upgrade of their Nokia/Checkpoint firewall and VPN infrastructure in order simplify the architecture and provide additional functionality to VPN users.
Data Centre Consolidation
Our client was a London Borough council which was embarking on an ambitious data centre consolidation and infrastructure refreshment project. The WAN and LAN networks were absolutely central to this, and Rohita’s role was to manage the network upgrade programme. Key challenges involved forecasting network usage for specific applications, and monitoring network performance before and after migration.
Migration to IP Telephony from Centrex
Our client is a college with 500 users spread across 4 campuses. Rohita Ltd.’s role was to project manage the college’s migration to Mitel IPT from a legacy Centrex system. A key challenge was the simultaneous migration to a new telecoms carrier, involving the installation of new circuits and a complicated number portability exercise.
Migration to IP Telephony from PABX
Our client is a software and services company with 400 users spread over two central and 3 branch offices in the UK. ROHITA’s role was to project manage their migration to a Cisco IPT system from an existing Nortel Meridian PBX system. Challenges included simultaneous LAN upgrade and recabling work.
