In this presentation, Nikhil Sharma, a technical marketing engineer at Cisco, discusses new features aimed at simplifying network troubleshooting on the Catalyst 4500 series switches. Sharma, who previously faced network troubleshooting challenges as a Cisco customer, introduces innovations designed to address these issues. He highlights that network administrators spend a significant portion of their time troubleshooting, often dealing with next-generation technologies like telepresence and video. The presentation focuses on three main features: Media Trace, IPSLA video operation, and the integration of Wireshark directly onto the switch.

Sharma explains that the new iOS XE release for the Catalyst 4500 includes the ability to perform Wireshark captures directly on the switch. This feature leverages the T-Shark binary, allowing administrators to capture and analyze network traffic without needing external span equipment. The Wireshark process is isolated in its own memory and CPU space, ensuring it does not interfere with other critical processes like spanning tree protocol or OSPF. This integration supports both data plane and control plane traffic, providing comprehensive packet analysis capabilities. The captured packets can be stored locally on the switch or transferred to a network management station for further analysis.

The presentation also covers Media Trace, a tool that traces the path of media streams across the network and identifies any changes or issues along the way. Media Trace uses RSVP as its underlying protocol, providing detailed statistics and alerts if there are changes in the path or if DSCP values are reset. Additionally, the performance monitor feature allows administrators to define and apply policies across multiple hops, automating the collection of RTP statistics and other relevant data. This combination of tools enables network administrators to quickly diagnose and resolve issues, ensuring their networks are ready for video and other high-bandwidth applications.

Dr. K. V. S. Ramarao’s presentation at Tech Field Day on March 29, 2012, delved into the evolution of data deduplication solutions and introduced Infineta’s unique approach to the problem. He began by explaining the basic concept of data deduplication, which involves maintaining a dynamic dictionary of previously seen data to avoid redundant transmissions. He traced the history of deduplication algorithms back to the Rabin algorithm from 1981, which addressed the string matching problem by using rolling hashes to efficiently find substrings within larger strings. This method reduced computational complexity but introduced the challenge of false positives, which Rabin mitigated using random irreducible polynomials to minimize the probability of hash collisions.

Ramarao then discussed subsequent advancements in deduplication algorithms, including Manber’s work in 1993 on file similarity and Broder’s application of these ideas to web page similarity in 1997. By 1999, Ross Williams had patented a method that applied these principles to deduplication, focusing on identifying identical parts between similar strings. Traditional deduplication methods, as Ramarao explained, involve partitioning data into chunks and using rolling hashes to find breakpoints, which are then used to identify and eliminate redundant data. However, these methods face significant scalability issues, particularly when dealing with large volumes of data at high speeds, due to the heavy computational and memory demands.

Infineta’s “secret sauce,” as Ramarao described, lies in its innovative approach to deduplication, which avoids the pitfalls of traditional methods. Instead of relying on large, variable-length chunks and sequential processing, Infineta uses a massively parallelizable algorithm that processes fixed-length data segments. This method involves selecting random positions within data packets and comparing small, fixed-size segments to a dictionary, allowing for partial matches and reducing the need for extensive memory and CPU resources. By implementing this in hardware, specifically FPGAs, Infineta achieves high throughput with minimal latency, making it suitable for high-speed data transfer scenarios. This approach not only improves deduplication efficiency but also ensures scalability, addressing the limitations of traditional deduplication solutions.

In a Tech Field Day presentation recorded on March 29, 2012, Arista co-founder Andy Bechtolsheim discussed the current challenges in networking and his approach to solving them. Bechtolsheim emphasized the importance of the EOS model of stateless agents, which keeps all the state in one database, making it easier to update other nodes from the primary node. This model is particularly useful for redundant supervisor switches and can be extended to multi-node systems. He also touched on the topic of OpenFlow, noting that while centralized management of a collection of switches is a common customer use case, replacing traditional routing with centralized routing agents is less practical due to the need for distributed routing to survive failures.

Bechtolsheim provided a critical perspective on the adoption of new networking standards and technologies. He pointed out that despite the initial excitement around OpenFlow, there have been no significant production deployments. He compared this to other standards like TRILL and FCOE, which have seen slow adoption despite being introduced years ago. The main challenge, according to Bechtolsheim, is that most customers have existing networks and are reluctant to adopt new architectures that do not interoperate with their current systems. He argued that the most popular and scalable deployment model today is ECMP (Equal-Cost Multi-Path), which is mature, reliable, and does not require the adoption of new, unproven technologies.

Bechtolsheim also highlighted the importance of centralized management and the role of silicon advancements in networking. He explained that Arista’s approach to centralized management, such as zero-touch provisioning, helps reduce operational expenses by minimizing the need for network engineers. He also discussed the use of various silicon chips from different vendors, emphasizing that Arista’s software stack allows them to choose the best chips available at any given time. This flexibility enables Arista to support new features and higher performance levels without reinventing the network. Bechtolsheim concluded by noting that while software-defined networking (SDN) and programmable network gear are important, the focus should be on solving real customer problems with robust, scalable solutions.
